Would it be possible to use clean uranium, and clean coal for power. It just seems that whenever we try to use depleted uranium, that when we mine and oxidize the uranium, it makes it more toxic to us. This is why I still think we need more research. Some question we could trap the uranium reactors, miles under the Earth. Some say that we now

# Demand for clean energy inspires new generation to innovate nuclear power

January 4, 2017

MILES O’BRIEN: Physicist Edwin Lyman is with the Union of Concerned Scientists. He says the promise of this new generation of nukes should be tempered by the uncertainties.
EDWIN LYMAN: Some non-water-cooled systems have a lower risk of certain types of accident, but they have greater risks of other kinds of accidents, or they introduce other security or safety issues, so there’s really no free lunch here.
MILES O’BRIEN: But the private sector is apparently not dissuaded. A D.C.-based think tank, Third Way, found more than 40 startups across the U.S. developing advanced nuclear power designs.
These atomic business plans have lured more than a billion dollars in investment.
LESLIE DEWAN, Transatomic Power: I think a lot of it might just be the changing demographics of nuclear engineers, that now there are a large number of young nuclear engineers who think, I have a really good idea. I’m going to raise some funding. I’m going to see if I can do this on my own.
How much do you have to worry about free fluorine?
MILES O’BRIEN: Leslie Dewan is one of the young entrepreneurs leading this revolution. She became enamored with some nuclear technology first developed 50 years ago at the Oak Ridge National Laboratory. It’s called a molten salt reactor, not table salt, liquid fluoride salts.
LESLIE DEWAN: A molten salt reactor uses liquid fuel, rather than solid fuel.
MILES O’BRIEN: Having uranium dissolved in liquid offers some safety advantages. If the fuel gets too hot, the liquid expands, and the uranium atoms become too dispersed to maintain a nuclear chain reaction. It shuts itself down.
And in the case of a station blackout, like Fukushima, the liquid fuel drains into a larger tank, where it cools down passively, no electricity needed. At Oak Ridge, they successfully ran and tested a molten salt reactor for four years, and it worked.
But building a reactor that can withstand something as corrosive as a very hot bath of salt is a huge engineering challenge. At Oak Ridge, the funding ended before they could work on that. So, the corrosion problem is the focus of early testing for Leslie Dewan’s startup company, Transatomic.
LESLIE DEWAN: We can make something that works for five years, that works for 10 years. Like, that, we certainly know. What we are trying to figure out now is whether we can use newer materials or new methods of corrosion control to extend the lifetime of the facility, because, ultimately, we care about making this low-cost.
If you have to replace your key components every 10 years, it’s not going to be cheaper than coal. And if it’s not cheaper than coal, then it’s not worth doing.
MILES O’BRIEN: Without a tax, or a cap, on carbon emissions, matching the cost of fossil fuels will likely be an impossible order for these new nuclear designs.
EDWIN LYMAN: We don’t put a lot of stock in seeing an alternative to a water-cooled reactor being developed anytime soon, certainly not quickly enough to make a dent in the greenhouse gas problem.
MILES O’BRIEN: But, in Idaho, they are pressing forward with urgency. In the U.S., there are currently about 100 nuclear reactors in operation. The majority of them are slated for retirement in the 2030s. What will replace them? Wind and solar? Not without a breakthrough in battery technology to store power on the grid.
NATHAN MYHRVOLD: The fate of the whole planet depends on us renewing our energy system with renewables and with nuclear. And if we step back from that, we are going to create a tremendous problem for future generations.
MILES O’BRIEN: Worries about waste, weapons proliferation and safety nearly derailed nuclear energy in the past. But the quest to meet rising demand for energy, without wrecking the planet, has put new nuclear technology back on the agenda.

Improving the selective extraction of spent uranium in nuclear waste clean-up

June 16, 2015

Driven by the need to find ways of separating, recycling and reducing nuclear waste, chemists at The University of Nottingham are developing our understanding of how uranium interacts with elements from around the periodic table to potentially help improve the selective extraction of spent uranium in nuclear waste clean-up.

# Recycling nuclear waste via advanced reactor design

May 28th, 2015

An advanced nuclear reactor under development by Hitachi could help solve the nuclear waste problem, and University of Michigan researchers were involved in verifying its safe performance through computer simulations.

The U-M team worked with colleagues at the Massachusetts Institute of Technology and the University of California, Berkeley. After more safety analysis, Hitachi plans to move forward with a prototype of the "resource-renewable boiling water reactor" in the next few years.

One of the major technological hurdles for nuclear energy is developing systems to dispose of the waste produced by typical reactors. It must be sealed away for hundreds of millennia while the radioactivity naturally decreases.

Hitachi's new design would burn off the longest-lived radioactive materials, called transuranics, shortening that isolation period to a few centuries. This would recycle the nuclear waste to produce yet more energy and reduce the amount that must be stowed away.

# Graphene, the finest filter

##### January 5, 2016

http://phys.org/news/2016-01-graphene-finest-filter.html#nRlv

Graphene can simplify production of heavy water and help clean nuclear waste by filtering different isotopes of hydrogen, University of Manchester research indicates.

Writing in Science, a team led by Sir Andre Geim demonstrated that using membranes made from graphene can act as a sieve, separating protons – nuclei of hydrogen – from heavier nuclei of hydrogen isotope deuterium.

The process could mean producing heavy water for nuclear power plants could be ten times less energy intensive, simpler and cheaper using graphene.

One of the hydrogen isotopes, deuterium, is widely used in analytical and chemical tracing technologies and, also, as heavy water required in thousands of tons for operation of nuclear power stations.

The heaviest isotope, tritium, is radioactive and needs to be safely removed as a byproduct of electricity generation at nuclear fission plants. Future nuclear technology is based on fusion of the two heavy isotopes.

The current separation technologies for production of heavy water are extremely energy intensive, and have presented a major scientific and industrial problem. Now graphene promises do so efficiently.

Researchers tested whether deuterons – nuclei of deuterium – can pass through graphene and its sister material boron nitride. They fully expected deuterons to easily pass through, as existing theory did not predict any difference in permeation for both isotopes.

The researchers were surprised to find that deuterons were not only effectively sieved out by their one atom thick membranes, but were sieved with a high separation efficiency.

The discovery makes monolayers of graphene and boron nitride attractive as separation membranes to enrich mixtures of deuterium and tritium.

Furthermore, the researchers showed that the separation is fully scalable. Using chemical-vapor-deposited (CVD) graphene, they built centimetre-sized devices to effectively pump out hydrogen from a mixture of deuterium and hydrogen.

Dr Marcelo Lozada-Hidalgo, University of Manchester postdoctoral researcher and first author of the paper, said: "This is really the first membrane shown to distinguish between subatomic particles, all at room temperature.

"Now that we showed that it is a fully scalable technology, we hope it will quickly find its way to real applications."

Professor Irina Grigorieva, who co-authored the research, said: "We were stunned to see that a membrane can be used to separate subatomic particles.

"It is a really simple set up. We hope to see applications of these filters not only in analytical and chemical tracing technologies but also in helping to clean nuclear waste from radioactive tritium."

Many have even mentioned about using genetically modified archaea (bacteria), that could eat and digest uranium, including other toxic waste. The bacteria could turn the toxic waste, into a different chemical structure, that may not be as toxic, or could biodegrade properly. However, some question if this type of bacteria, could pose a threat to the environment.

------------------------------------

# For uranium cleanup ... bacteria?

http://news.stanford.edu/news/2006/may24/criddle-052406.html

Bacteria are back
Bioremediation was used in the 1980s to clean up toxic organics, mainly spills of fuels and solvents. Bacteria basically ate the fuels—chomping down long-chain hydrocarbons—or they "breathed" the solvents and created nontoxic forms.
"Microorganisms also 'breathe' metals like uranium, converting it into a form that is immobile because it does not appreciably dissolve in water," said Nyman, a doctoral student whose laboratory studies helped to guide operations in the field. After microbes convert the uranium, it's "just sitting there, like a rock," Criddle said. "In future studies, we hope to see how stable we can make that 'rock.' Ideally, it will remain in that form for thousands of years."

# Scientists develop material to remove radioactive contaminants from drinking water

##### April 13, 2011
A combination of forest byproducts and crustacean shells may be the key to removing radioactive materials from drinking water, researchers from North Carolina State University have found."As we're currently seeing in Japan, one of the major health risks posed by nuclear accidents is radioactive iodide that dissolves into drinking water. Because it is chemically identical to non-radioactive iodide, the human body cannot distinguish it – which is what allows it to accumulate in the thyroid and eventually lead to cancer," says Dr. Joel Pawlak, associate professor of forest biomaterials. "The material that we've developed binds iodide in water and traps it, which can then be properly disposed of without risk to humans or the environment."

# Technique could set new course for extracting uranium from seawater

##### December 17, 2015
An ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors.

http://phys.org/news/2015-12-technique-uranium-seawater.html

Some people think that this technology could be useful, to cleanup excess uranium, from ocean water. Many people still believe, that there are still better sources of energy, than using uranium for energy.

# Metal foams could provide lightweight radiation shielding

• July 22, 2015

Radiation generally comes under the heading of "things you want to stay away from," so it's no surprise that radiation shielding is a high priority in many industries. However, current shielding is bulky and heavy, so a North Carolina State University team is developing a new lightweight shielding based on foam metals that can block X-rays, gamma rays, and neutron radiation, as well as withstanding high-energy impact collisions.

Researchers awarded patent for tokamak device, would turn nuclear waste into fuel

September 13, 2012

University of Texas at Austin physicists have been awarded a U.S. patent for an invention that could someday be used to turn nuclear waste into fuel, thus removing the most dangerous forms of waste from the fuel cycle.

The researchers—Mike Kotschenreuther, Prashant Valanju and Swadesh Mahajan of the College of Natural Sciences—have patented the concept for a novel fusion-fission hybrid nuclear reactor that would use nuclear fusion and fission together to incinerate nuclear waste. Fusion produces energy by fusing atomic nuclei, and fission produces energy by splitting atomic nuclei.

The process of burning the waste would also produce energy. The researchers' goal is to eliminate 99 percent of the most toxic transuranic waste from nuclear fission reactors.

"The potential for this kind of technology is enormous," said Mahajan, professor of physics. "Now that we have the patent, we hope this will open up opportunities to engage with the research and development community to further this potentially world-changing technology."

The researchers' patent covers a tokamak device, which uses magnetic fields to produce fusion reactions. The patented tokamak is surrounded by an area that would house a nuclear waste fuel source and waste by-products of the nuclear fuel cycle. The device is driven by a transformational technology called the Super X Divertor.

The Super X Divertor is a crucial technology that has the capacity to safely divert the enormous amounts of heat out of the reactor core to keep the reactor producing energy.

Toxic nuclear waste is stored at sites around the U.S., and the need to store nuclear waste is widely considered to be a major disadvantage associated with nuclear energy.

The physicists' invention could someday drastically decrease the need for any additional or expanded geological repositories, making nuclear power cleaner and more viable.

The patented hybrid reactor is currently in a conceptual phase.

The Super X Divertor, however, is being installed as the centerpiece of a $40 million upgrade of the MAST tokamak in the United Kingdom. This installation is a critical step forward in testing the Super X Divertor experimentally. It is not covered by the U.S. patent but is the technology invented by the University of Texas at Austin physicists. http://phys.org/news/2012-09-awarded-patent-tokamak-device-nuclear.html#nRlv --------------------- # Fuel comparison With a complete combustion or fission, approx. 8 kWh of heat can be generated from 1 kg of coal, approx. 12 kWh from 1 kg of mineral oil and around 24,000,000 kWh from 1 kg of uranium-235. Related to one kilogram, uranium-235 contains two to three million times the energy equivalent of oil or coal. The illustration shows how much coal, oil or natural uranium is required for a certain quantity of electricity. Thus, 1 kg natural uranium - following a corresponding enrichment and used for power generation in light water reactors - corresponds to nearly 10,000 kg of mineral oil or 14,000 kg of coal and enables the generation of 45,000 kWh of electricity. https://www.euronuclear.org/info/encyclopedia/f/fuelcomparison.htm ------- Honestly, we need more studies on the subjects of clean uranium energy, inducing clean coal. There are mixed articles, on both of these subjects. However, some question if trapping excess carbon, is still the best way to produce energy. We still believe that many other sources of energy are being suppressed. Such as hydrogen energy, energy from Nikola Tesla, and fusion technology. ------ Renewables Aren’t Enough. Clean Coal Is the Future https://www.wired.com/2014/03/clean-coal/ ----------- Some articles are for clean coal. Other articles are against clean coal. ----- # The Myth of Clean Coal: Analysis ## Jul 14, 2011 ## Will coal become the clean, green fuel of the future? Not so fast. http://www.popularmechanics.com/science/energy/a4947/4339171/ ------ ## Can Coal Ever Be Clean? ### April 2014 ### It’s the dirtiest of fossil fuels. We burn eight billion tonsof it a year, with growing consequences.The world must face the question. American Electric Power’s Mountaineer Plant, on the Ohio River in New Haven, West Virginia, inhales a million pounds of Appalachian coal every hour. The coal arrives fresh from the ground, on barges or on a conveyor belt from a mine across the road. Once inside the plant, the golf-ball-size lumps are ground into dust as fine as face powder, then blown into the firebox of one of the largest boilers in the world—a steel box that could easily swallow the Statue of Liberty. The plant’s three steam-powered turbines, painted blue with white stars, supply electricity round the clock to 1.3 million customers in seven states. Those customers pay about a dime per kilowatt-hour, or roughly$113 a month, to power the refrigerators, washers, dryers, flat screens, and smartphones, to say nothing of the lights, of an average household. And as Charlie Powell, Mountaineer’s plant manager, often said, even environmentalists like to keep the lights on.
The customers pay not a cent, however, nor does American Electric Power (AEP), for the privilege of spewing six to seven million metric tons of carbon dioxide into the atmosphere every year from Mountaineer’s thousand-foot-high stack. And that’s the problem. Carbon is dumped without limit because in most places it costs nothing to do so and because there is, as yet, no law against it in the U.S. But in 2009 it looked as if there might soon be a law; the House of Representatives had already passed a bill that summer. AEP, to its credit, decided to get ahead of it.
That October, Mountaineer began a pioneering experiment in carbon capture. Powell oversaw it. His father had worked for three decades at a coal-fired power plant in Virginia; Powell himself had spent his career at Mountaineer. The job was simple, he said: “We burn coal, make steam, and run turbines.” During the experiment, though, it got a bit more complicated. AEP attached a chemical plant to the back of its power plant. It chilled about 1.5 percent of Mountaineer’s smoke and diverted it through a solution of ammonium carbonate, which absorbed the CO₂. The CO₂ was then drastically compressed and injected into a porous sandstone formation more than a mile below the banks of the Ohio.

The system worked. Over the next two years AEP captured and stored more than 37,000 metric tons of pure carbon dioxide. The CO₂ is still underground, not in the atmosphere. It was only a quarter of one percent of the gas coming out the stack, but that was supposed to be just the beginning. AEP planned to scale up the project to capture a quarter of the plant’s emissions, or 1.5 million tons of CO₂ a year. The company had agreed to invest $334 million, and the U.S. Department of Energy (DOE) had agreed to match that. But the deal depended on AEP being able to recoup its investment. And after climate change legislation collapsed in the Senate, state utility regulators told the company that it could not charge its customers for a technology not yet required by law. In the spring of 2011 AEP ended the project. The maze of pipes and pumps and tanks was dismantled. Though small, the Mountaineer system had been the world’s first to capture and store carbon dioxide directly from a coal-fired electric plant, and it had attracted hundreds of curious visitors from around the world, including China and India. “The process did work, and we educated a lot of people,” said Powell. “But geez-oh-whiz—it’s going to take another breakthrough to make it worth our while.” A regulatory breakthrough above all—such as the one Obama promised last summer—but technical ones would help too. Capturing carbon dioxide and storing or “sequestering” it underground in porous rock formations sounds to its critics like a techno-fix fantasy. But DOE has spent some$6.5 billion over the past three decades researching and testing the technology. And for more than four decades the oil industry has been injecting compressed carbon dioxide into depleted oil fields, using it to coax trapped oil to the surface. On the Canadian Great Plains this practice has been turned into one of the world’s largest underground carbon-storage operations.
Since 2000 more than 20 million metric tons of carbon dioxide have been captured from a North Dakota plant that turns coal into synthetic natural gas, then piped 200 miles north into Saskatchewan. There the Canadian petroleum company Cenovus Energy pushes the CO₂ deep into the Weyburn and Midale fields, a sprawling oil patch that had its heyday in the 1960s. Two to three barrels of oil are dissolved out of the reservoir rock by each ton of CO₂, which is then reinjected into the reservoir for storage. There it sits, nearly a mile underground, trapped under impermeable layers of shale and salt.
For how long? Some natural deposits of carbon dioxide have been in place for millions of years—in fact the CO₂ in some has been mined and sold to oil companies. But large and sudden releases of CO₂ can be lethal to people and animals, particularly when the gas collects and concentrates in a confined space. So far no major leaks have been documented at Weyburn, which is being monitored by the International Energy Agency, or at any of the handful of other large storage sites around the world. Scientists consider the risk of a catastrophic leak to be extremely low.
They worry more about smaller, chronic leaks that would defeat the purpose of the enterprise. Geophysicists Mark Zoback and Steven Gorelick of Stanford University argue that at sites where the rock is brittle and faulted—most sites, in their view—the injection of carbon dioxide might trigger small earthquakes that, even if otherwise harmless, might crack the overlying shale and allow CO₂ to leak. Zoback and Gorelick consider carbon storage “an extremely expensive and risky strategy.” But even they agree that carbon can be stored effectively at some sites—such as the Sleipner gas field in the North Sea, where for the past 17 years the Norwegian oil company Statoil has been injecting about a million tons of CO₂ a year into a brine-saturated sandstone layer half a mile below the seabed. That formation has so much room that all that CO₂ hasn’t increased its internal pressure, and there’s been no sign of quakes or leaks.

Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices.

Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors. The prototype generators work by harnessing the movement of a sheet of rubber coated on one side with spores. The sheet bends when it dries out, much as a pine cone opens as it dries or a freshly fallen leaf curls, and then straightens when humidity rises. Such bending back and forth means that spore-coated sheets or tiny planks can act as actuators that drive movement, and that movement can be harvested to generate electricity. http://wyss.harvard.edu/viewpressrelease/137/getting-a-charge-from-changes-in-humidity --------------------- # A new clean nuclear fusion reactor has been designed ##### January 14, 2013 http://phys.org/news/2013-01-nuclear-fusion-reactor.html#nRlv A researcher at the Universidad politécnica de Madrid (UPM, Spain) has patented a nuclear fusion reactor by inertial confinement that, apart from be used to generate electric power in plants, can be applied to propel ships. This invention is the result of a work carried out by the Professor José Luis González Díez from the Higher Technical School of Naval Engineering of the UPM, who has contributed to solve the problem of contamination risk associated with the generation of nuclear fission power. It is a design of a fusion nuclear reactor by laser ignition of 1000 MWe that uses as fuel hydrogen isotopes that can be extracted from water allowing us a significant saving in fuel. The nuclear fission is generally considered as a dangerous energy due to its contaminant risks of radioactive waste resulting from the electricity generation process. The past events occurred in Japan after the tsunami of 2011 increased the risk perception of this type of energy generation what has provoked that research on alternative ways to obtain energy have gained more importance than ever. For years, nuclear fusion was studied as an alternative to nuclear fission because of its remarkable advantages for security and financial issues. However, today, there is not working any fusion reactor to produce continuous electrical energy of high voltage. -------------- # Electrostatic nuclear accelerator #### An electrostatic nuclear accelerator is one of the two main types of particle accelerators, where charged particles can be accelerated by subjection to a static high voltage potential. The static high voltage method is contrasted with the dynamic fields used in oscillating field particle accelerators. Owing to their simpler design, historically these accelerators were developed earlier. These machines are operated at lower energy than some larger oscillating field accelerators, and to the extent that the energy regime scales with the cost of these machines, in broad terms these machines are less expensive than higher energy machines, and as such they are much more common. Many universities world wide have electrostatic accelerators for research purposes. #### http://en.wikipedia.org/wiki/Electrostatic_nuclear_accelerator --------------------- May 25, 2001 # TESLA project goes public http://cerncourier.com/cws/article/cern/28450 At a major event held at the DESY laboratory in March (see News May 2000), the international TESLA collaboration, together with the members of various study groups, released the TESLA Technical Design Report. This five-volume opus presented the final facts and figures concerning a grand plan for the future: the "TeV-Energy Superconducting Linear Accelerator", a 33 km electron-positron linear collider with an integrated X-ray laser laboratory. To be built near the DESY laboratory in Hamburg, the facility would not only provide particle collision energies of 500 GeV - which could be increased to 800 GeV - but also include powerful X-ray lasers that would open up new research opportunities in a variety of fields, ranging from condensed matter physics through chemistry and material science to structural biology. It is widely acknowledged among particle physicists that a linear accelerator colliding electrons and positrons is the ideal machine to complement CERN's Large Hadron Collider, which is due to start operation in 2006. As well as the TESLA collaboration, plans for similar next-generation linear electron-positron colliders are being worked on by other teams. SLAC in the US and KEK in Japan are jointly developing two similar designs - known respectively as the Next Linear Collider and the Japan Linear Collider - which could be ready for construction at around the same time as TESLA. CERN is also working on a next-generation collider, CLIC. However, the TESLA proposal is the first to be fully costed and made public. It is also the only project to include an X-ray laser laboratory and thus to address a large interdisciplinary research community. ------------------------ ---------------- ---------------- Chapter 2: CERN ---------------- ---------------- --------------------- Doing experiments with the interaction of antimatter, including chemicals such as uranium, have many people and scientists concerned. As we know, smashing certain chemicals, such as uranium at very high speeds, could create a giant catastrophic explosion on the planet. ---------------------------- Gravitational interaction of antimatter https://en.wikipedia.org/wiki/Gravitational_interaction_of_antimatter The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. While the overwhelming consensus among physicists is that antimatter will attract both matter and antimatter at the same rate that matter attracts matter, there is a strong desire to confirm this experimentally. Antimatter's rarity and tendency to annihilate when brought into contact with matter makes its study a technically demanding task. Most methods for the creation of antimatter (specifically antihydrogen) result in high-energy particles and atoms of high kinetic energy, which are unsuitable for gravity-related study. In recent years, first ALPHA [1][2] and then ATRAP [3] have trapped antihydrogen atoms at CERN; in 2013 ALPHA used such atoms to set the first free-fall loose bounds on the gravitational interaction of antimatter with matter, with a relative precision of the measurement of ±100%, not enough for a clear scientific statement about the sign of gravity acting on antimatter. Future experiments need to be performed with higher precision, either with beams of antihydrogen (AEGIS or GBAR) or with trapped antihydrogen (ALPHA). ------------------ # CERN researchers confirm existence of the Force ##### April, 2015 Researchers at the Large Hadron Collider just recently started testing the accelerator for running at the higher energy of 13 TeV, and already they have found new insights into the fundamental structure of the universe. Though four fundamental forces – the strong force, the weak force, the electromagnetic force and gravity – have been well documented and confirmed in experiments over the years, CERN announced today the first unequivocal evidence for the Force. "Very impressive, this result is," said a diminutive green spokesperson for the laboratory. http://phys.org/news/2015-04-cern.html#jCp -------------- # Meson f0(1710) could be so-called “glueball” particle made purely of nuclear force Terms to describe the strange world of quantum physics have come to be quite common in our lexicon. Who, for instance, hasn't at least heard of a quark, or a gluon or even Schrodinger's cat? Now there's a new name to remember: "Glueball." A long sought-after exotic particle, and recently claimed to have been detected by researchers at TU Wien, the glueball's strangest characteristic is that it is composed entirely of gluons. In other words, it is a particle created from pure force. First mooted as a particle in 1972 when physicists Murray Gell-Mann and Harald Fritsch wondered about possible bound states of recently-discovered gluons, scientists have sought the particle in the intervening decades. Originally dubbed "gluonium," but now called glueballs, these strange particles of pure force are exceptionally unstable and can only be indirectly detected by monitoring their decay as they disassemble into lesser particles. More recently, physics Professor Anton Rebhan and his PhD student Frederic Brünner from TU Wien have theorized that a strong nuclear decay resonance, called f0(1710), observed in the data from a number of particle accelerator experiments is strong evidence for the elusive glueball particle... http://www.gizmag.com/meson-f01710-glueball-particle/39866/?li_source=LI&li_medium=default-widget ------------------ # Stephen Hawking Says 'God Particle' Could Wipe Out the Universe September 08, 2014 ( Simulated data from the Large Hadron Collider particle detector shows the Higgs boson produced after two protons collide. ) Stephen Hawking bet Gordon Kane$100 that physicists would not discover the Higgs boson.

# Big Chill Sets in as RHIC Physics Heats Up

## Run 14 promises highest collision rates enabling exploration of detailed properties of early-universe matter

Monday, February 03, 2014

UPTON, NY—If you think it's been cold outside this winter, that's nothing compared to the deep freeze setting in at the Relativistic Heavy Ion Collider (RHIC), the early-universe-recreating "atom smasher" at the U.S. Department of Energy's Brookhaven National Laboratory. Brookhaven's accelerator physicists have begun pumping liquid helium into RHIC's 1,740 superconducting magnets to chill them to near absolute zero (-273 degrees Celsius—the coldest anything can get) in preparation for the collider's next physics run.

Once that extreme subzero temperature is reached, enabling the magnets to operate with zero energy loss, the physicists will begin injecting beams of gold ions and steering them into head-on collisions at nearly the speed of light. Those collisions create temperatures at the opposite extreme of the temperature scale—4 trillion degrees Celsius, or 250,000 times hotter than the center of the sun—to produce RHIC's signature "perfect" liquid quark-gluon plasma, a stand in for what the universe was like an instant after the Big Bang. During this experimental run, the 14th at this nuclear physics scientific user facility, scientists will conduct detailed studies of the primordial plasma's properties and fill in some missing data points to plot its transition to the matter we see in the universe today

# The puzzle of the origin of elements in the universe

##### December 17, 2015
A rare nuclear reaction that occurs in red giants has been observed for the first time at the Gran Sasso National Laboratory in Italy. This result was achieved by the LUNA experiment, the world's only accelerator facility running deep underground.

The LUNA experiment at the INFN Gran Sasso National Laboratory in Italy has observed a rare nuclear reaction that occurs in giant red stars, a type of star in which our sun will also evolve. This is the first direct observation of sodium production in these stars, one of the nuclear reactions that is fundamental for the formation of the elements that make up the universe. The study has been published in Physical Review Letters.

LUNA (Laboratory for Underground Nuclear Astrophysics) is a compact linear accelerator. It is the only one in the world installed in an underground facility, shielded against cosmic rays. The experiment aims to study the nuclear reactions that take place inside stars where, like in an intriguing and amazing cosmic kitchen, the elements that make up matter are formed and then driven out by gigantic explosions and scattered as cosmic dust.

Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider (RHIC)-an "atom smasher" dedicated to nuclear physics research at the U.S. Department of Energy's Brookhaven National Laboratory-scientists have come to a new understanding of how particles are produced in these collisions. This understanding represents a paradigm shift consistent with the presence of a saturated state of gluons, super-dense fields of the glue-like particles that bind the building blocks of ordinary matter.

# Physicists search for signs of supersymmetry

##### December 17, 2015

The first results from direct searches for new physics were announced today from CERN's energy-upgraded Large Hadron Collider (LHC). Among these results was a search for signs of a new theory called supersymmetry in which members of the University of Bristol particle physics group have played a leading role.

The LHC is the world's highest energy particle accelerator. After an almost two year shutdown and several months' re-commissioning, the LHC delivered physics data to its experiments from June to November this year at the unprecedented energy of 13 TeV, almost double the collision energy of its first run. The energy of the colliding protons is such that new particles much heavier than the proton can be created including the famous Higgs boson, and possibly even heavier and more exotic particles hypothesised in new physics theories. One such theory is called supersymmetry, which predicts an exotic partner for each currently known particle type.

# Four new elements confirmed

January 4, 2016

http://www.gizmag.com/new-periodic-table-elements-confirmed/41139/

Chemistry textbooks are in need of a rewrite with the addition of four new elements to the Periodic Table. The International Union of Pure and Applied Chemistry (IUPAC) has confirmed the existence of four new elements with the atomic numbers 113, 115, 117, and 118, which were discovered by laboratories in Japan, the United States, and Russia. This bumper group of new elements completes the 7th row of the Periodic Table and clears the way for the discoverers to start thinking up names for them.

Until now, elements 113, 115, 117, and 118 have only been known from their gaps in the table and the temporary names ununtrium (Uut), ununpentium (Uup), ununseptium (Uus), and ununoctium (Uuo). Now, thanks to RIKEN in Japan; the Joint Institute for Nuclear Research in Dubna, Russia; Lawrence Livermore National Laboratory (LLNL), California; and Oak Ridge National Laboratory, (ORNL), Tennessee, these elements that do not exist in nature have been confirmed to have been created for the first time.

The fourth IUPAC and the International Union of Pure and Applied Physics (IUPAP) Joint Working Party (JWP) reviewed the findings of the discoverers and, based on a criteria set out in 1991, have confirmed them. Elements 115 and 117 were found by the Joint Institute for Nuclear Research, LLNL, and ORNL. Element 118 was found by the Joint Institute and LLNL, and 113 was found by RIKEN.

The periodic table in its modern form was invented by Russian chemistry professor Dmitri Mendeleev in 1869 and lists elements according to their atomic numbers based on the number of protons in their nuclei. Its odd shape, which is familiar to anyone trying to stay awake in chemistry class, is due to the discovery that by arranging the elements to group them by their chemical properties and electron configurations, it becomes a graphic representation of objective reality.
In other words, chemists could not only use the table to describe known elements, but also predict the existence and properties of unknown elements that were yet to be discovered. This makes the IUPAC announcement particularly important because it means that an entire row or period of the table has now been filled in thanks, in part, to this predictability.

Though many of the new elements were discovered as far back as 2004, the tricky bit has been proving that they exist. In the 19th century, any competent chemist could determine if a substance was a pure element, but the new elements reside in a part of the table where the atoms are super heavy and so unstable that they exist for less than a thousandth of a second.

Element 113, for example, was created by using a linear accelerator to bombard a thin layer of bismuth with zinc ions travelling at about ten percent of the speed of light in hope that, in rare instances, the bismuth and zinc atoms would fuse to form a element. The resulting super-heavy atom of 113 would then decay and turn into other unstable radioactive isotopes, which would decay nearly as fast.

The result was that the scientists who created the new element had to spend years tracing back the event through a labyrinth of isotopic breakdowns to prove that they descended from the new element. Then, the JWP of the IUPAC had to review the literature to make sure no mistakes were made.
Now that the elements are confirmed, the discoverers can officially apply permanent names and symbols to them. The proposed names and two-letter symbols will be checked by the Inorganic Chemistry Division of IUPAC and then be subjected to a public review for five months to make sure they conform to the standards of consistency, translatability into other languages, and historic use. Typically, names have been derived from mythology, minerals, geography, or the name of a scientist.
One other interesting point about the new elements is that it opens the way to the search for an "island of stability." That is, a region beyond the current Periodic Table where new superheavy elements will become stable and exist long enough to allow for conventional chemistry experiments.

# The perfect liquid -- now even more perfect

##### January 17, 2012

Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can be. Recent results at the Vienna University of Technology suggest that this limit can be broken -- making the world's "most perfect fluid" even more perfect.

How liquid can a fluid be? This is a question particle physicists at the Vienna University of Technology have been working on. The "most perfect liquid" is nothing like water, but the extremely hot quark-gluon-plasma which is produced in heavy-ion collisions at the Large Hadron Collider at CERN. New theoretical results at Vienna UT show that this quark-gluon plasma could be even less viscous than was deemed possible by previous theories. The results were published in Physical Review Letters and highlighted as an "editors' selection".

Highly viscous liquids (such as honey) are thick and have strong internal friction, quantum liquids, such as super fluid helium can exhibit extremely low viscosity. In 2004, theorists claimed that quantum theory provided a lower bound for viscosity of fluids. Applying methods from string theory, the lowest possible ratio of viscosity to the entropy density was predicted to be ħ/4π (with the Planck-constant ħ). Even super fluid helium is far above this threshold. In 2005, measurements showed that quark-gluon-plasma exhibits a viscosity just barely above this limit. However, this record for low viscosity can still be broken, claims Dominik Steineder from the Institute for Theoretical Physics at Vienna UT. He obtained this remarkable result working as a PhD-student with Professor Anton Rebhan.

# Linear particle accelerator

https://en.wikipedia.org/wiki/Linear_particle_accelerator

A linear particle accelerator (often shortened to linac) is a type of particle accelerator that greatly increases the kinetic energy of charged subatomic particles or ions by subjecting the charged particles to a series of oscillating electric potentials along a linear beamline; this method of particle acceleration was invented by Leó Szilárd. It was patented in 1928 by Rolf Widerøe, who also built the first operational device at the RWTH Aachen University in 1928, influenced by a publication of Gustav Ising.

Linacs have many applications: they generate X-rays and high energy electrons for medicinal purposes in radiation therapy, serve as particle injectors for higher-energy accelerators, and are used directly to achieve the highest kinetic energy for light particles (electrons and positrons) for particle physics.
The design of a linac depends on the type of particle that is being accelerated: electrons, protons or ions. Linacs range in size from a cathode ray tube (which is a type of linac) to the 3.2-kilometre-long (2.0 mi) linac at the SLAC National Accelerator Laboratory in Menlo Park, California.

Antimatter

In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges, as well as other particle properties such as lepton and baryon numbers and quantum spin. Collisions between particles and antiparticles lead to the annihilation of both, giving rise to variable proportions of intense photons (gamma rays), neutrinos, and less massive particle–antiparticle pairs. The mass of any produced neutrinos is negligible, while they contain energy that generally continues to be unavailable after the release of particle–antiparticle annihilation. The total consequence of annihilation is a release of energy available for work, proportional to the total matter and antimatter mass, in accord with the mass–energy equivalence equation, E = mc2

The antimatter factory: inside the project that could power fusion and annihilation lasers

August 28, 2013

http://www.theverge.com/2013/8/28/4659834/unlocking-the-positron-fusion-annihilation-laser

Physicists have been chasing antimatter technology for more than 80 years now — driven by the promise of oppositely oriented particles that explode in a burst of energy whenever they make contact with their more common counterpart. If we could tame antimatter, those explosions could be used to power a new generation of technology, from molecular scanners to rocket engines to the so-called "annihilation laser," a tightly concentrated energy beam fueled by annihilating positrons. But while scientists have seen recent breakthroughs in creating the particles, they still have trouble capturing and containing them.

That progress has left us closer to workable antimatter than ever before, and parallel projects are already working on novel devices to cool and trap the particles, along with new magnetic arrays to keep them stable. With the right funding, experts estimate we could see the dawn of the positron age in as few as five years. Positron Dynamics is one key player in the new wave of technology, working on an innovative method for cooling down and capturing positrons, the antimatter equivalent of the common electron. Whenever a positron and an electron meet, they annihilate each other, which presents a serious challenge for anyone working with them. It’s particularly difficult because electrons are literally everywhere, floating in clouds around essentially every atom in the universe. Right now, the best solution for cooling the positrons is running them through a block of frozen neon (called a "moderator"), which offers a minimum of stray electrons. But the system only catches roughly one in 100 positrons, and in the 30 years it’s been in use, no one’s been able to improve on it.

After 85-year search, massless particle with promise for next-generation electronics found

July 16, 2015

An international team led by Princeton University scientists has discovered Weyl fermions, an elusive massless particle theorized 85 years ago. The particle could give rise to faster and more efficient electronics because of its unusual ability to behave as matter and antimatter inside a crystal, according to new research.

The researchers report in the journal Science July 16 the first observation of Weyl fermions, which, if applied to next-generation electronics, could allow for a nearly free and efficient flow of electricity in electronics, and thus greater power, especially for computers, the researchers suggest.

Proposed by the mathematician and physicist Hermann Weyl in 1929, Weyl fermions have been long sought by scientists because they have been regarded as possible building blocks of other subatomic particles, and are even more basic than the ubiquitous, negative-charge carrying electron (when electrons are moving inside a crystal). Their basic nature means that Weyl fermions could provide a much more stable and efficient transport of particles than electrons, which are the principle particle behind modern electronics.

Warp Drive, When? Status of Antimatter

http://www.nasa.gov/centers/glenn/technology/warp/antistat.html

Antimatter is real stuff, not just science fiction. Antimatter is firmly in the realm of science with some aspects even entering the technology realm. There is also a lot of speculation about what one might do with antimatter.

What is Antimatter?

Antimatter is matter with its electrical charge reversed. Anti-electrons, called "positrons," are like an electron but with a positive charge. Antiprotons are like protons with a negative charge. Positron, antiprotons and other antiparticles can be routinely created at particle accelerator labs, such as CERN in Europe, and can even be trapped and stored for days or weeks at a time. And just last year, they made antihydrogen for the first time. It didn’t last long, but they did it. Also, Antimatter is NOT antigravity. Although it has not been experimentally confirmed, existing theory predicts that antimatter behaves the same to gravity as does normal matter.

Technology is now being explored to make antimatter carrying cases, to consider using antimatter for medical purposes, and to consider how to make antimatter rockets.

The catch?

Right now it would cost about One-Hundred-Billion dollars to create one milligram of antimatter. One milligram is way beyond what is needed for research purposes, but that amount would be needed for large scale applications. To be commercially viable, this price would have to drop by about a factor of Ten-Thousand.

And what about using antimatter for power generation? - not promising.

It costs far more energy to create antimatter than the energy one could get back from an antimatter reaction. Right now standard nuclear reactors, which take advantage of the decay of radioactive substances, are far more promising as power generating technology than antimatter. Something to keep in mind, too, is that antimatter reactions - where antimatter and normal matter collide and release energy, require the same safety precautions as needed with nuclear reactions.

New methods to make longer streams of plasma with greater longevity could lead to laser-powered lightning rods

September 24, 2015

( A picture of a femtosecond laser. The laser beam itself is invisible (800nm), but due to the formation of a plasma channel, the beam emits (visible) white light. )

Benjamin Franklin invented the lightning rod 250 years ago to protect people and buildings from lightning strikes. Someday, those metal poles may be replaced with lasers.

A team of researchers from The Hebrew University of Jerusalem, Israel, have demonstrated new techniques that bring lasers as lighting rods closer to reality.

When a powerful laser beam shoots through the air, it ionizes the molecules, leaving a thin trail of hot, ionized particles in its wake. Because this stream of plasma conducts electricity, it could be used to channel away a potentially damaging lightning bolt.

The researchers found ways to make the length of such a plasma channel reach more than 10 times longer—a necessary advance for using the channel to redirect a lightning strike.

Researchers build real-time tunable plasmon laser

4/24/2015

Traditionally, light can only ever be focused down to a point half the size of its frequency—aka the diffraction limit. Scientists have found a way around that limit, however, by building what are known as plasmon lasers, which are lasers that couple their beam with plasmons (oscillating surface electrons) on the surface of metals—gold for example, arranged in an array. But that approach has had its limitations as well, because it has had to rely on a solid bit of material called the gain—such lasers could not be tuned very easily, and not in real-time at all. In this new effort, the researchers report that they have found a way to use a liquid material as the gain, and because of that, are able to tune their laser in real time.

# X marks the spot: Researchers confirm novel method for controlling plasma rotation

June 23rd, 2015

Rotation is key to the performance of salad spinners, toy tops, and centrifuges, but recent research suggests a way to harness rotation for the future of mankind's energy supply. In papers published in Physics of Plasmas in May and Physical Review Letters this month, Timothy Stoltzfus-Dueck, a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), demonstrated a novel method that scientists can use to manipulate the intrinsic - or self-generated - rotation of hot, charged plasma gas within fusion facilities called tokamaks.

Such a method could prove important for future facilities like ITER, the huge international tokamak under construction in France that will demonstrate the feasibility of fusion as a source of energy for generating electricity. ITER's massive size will make it difficult for the facility to provide sufficient rotation through external means.

# Extending life of plasma channels could allow lasers to be used as lightning rods

#### http://www.gizmag.com/plasma-channels-laser-lightning-rods/39588/

Today's simple metal lightning rods may be on their way to obsolescence. That's because scientists at The Hebrew University of Jerusalem are developing a high-tech alternative that could potentially reach higher and be more effective – laser lightning rods.

When a high-power laser is shot into the sky, it ionizes airborne molecules in the process. As a result, even once the laser itself is shut off, a trail of ionized particles known as a plasma channel is left in its place. Plasma channels conduct electricity, not unlike a good ol' steel rod.

Led by scientist Jenya Papeer, the Jerusalem team successfully created plasma channels measuring 100 microns in diameter, by firing a laser in pulses lasting just 100 femtoseconds each. Unfortunately, however, after three nanoseconds the plasma cooled off and the channels ceased to exist.

In order to boost those trails' longevity by a factor of 10, the researchers added a second laser that is fired in 10-nanosecond bursts along the path of the first one. Its wider beam envelopes the plasma created by the first beam, keeping it hot and conductive. By boosting the power of that second laser, or even by adding additional beams, it is hoped that the lifespan and the length of the plasma channels could be lengthened further.

Speaking of which, though, the first plasma channels to be produced were only a meter (3.3 ft) long. The researchers addressed this limitation by creating an array of lenses that change the way in which the laser is focused. As a result, it now creates a series of three one-meter-long channels linked end-to-end, effectively forming one 3-meter plasma channel.

That said, by further adjusting the focus and using a powerful enough laser, it should be possible to produce any number of linked plasma channels, creating a lightning rod of any desired length.

A paper on the research will be presented on Oct. 22nd at the Frontiers in Optics conference, in San Jose, California.

# Kilotesla Magnetic Field due to a Capacitor-Coil Target Driven by High Power Laser

Published
Laboratory generation of strong magnetic fields opens new frontiers in plasma and beam physics, astro- and solar-physics, materials science, and atomic and molecular physics. Although kilotesla magnetic fields have already been produced by magnetic flux compression using an imploding metal tube or plasma shell, accessibility at multiple points and better controlled shapes of the field are desirable. Here we have generated kilotesla magnetic fields using a capacitor-coil target, in which two nickel disks are connected by a U-turn coil. A magnetic flux density of 1.5 kT was measured using the Faraday effect 650 μm away from the coil, when the capacitor was driven by two beams from the GEKKO-XII laser (at 1 kJ (total), 1.3 ns, 0.53 or 1 μm, and 5 × 1016 W/cm2).

# Seeding magnetic fields for laser-driven flux compression in high-energy-density plasmas.

2009 Apr

A compact, self-contained magnetic-seed-field generator (5 to 16 T) is the enabling technology for a novel laser-driven flux-compression scheme in laser-driven targets. A magnetized target is directly irradiated by a kilojoule or megajoule laser to compress the preseeded magnetic field to thousands of teslas. A fast (300 ns), 80 kA current pulse delivered by a portable pulsed-power system is discharged into a low-mass coil that surrounds the laser target. A >15 T target field has been demonstrated using a <100 J capacitor bank, a laser-triggered switch, and a low-impedance (<1 Omega) strip line. The device has been integrated into a series of magnetic-flux-compression experiments on the 60 beam, 30 kJ OMEGA laser [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)]. The initial application is a novel magneto-inertial fusion approach [O. V. Gotchev et al., J. Fusion Energy 27, 25 (2008)] to inertial confinement fusion (ICF), where the amplified magnetic field can inhibit thermal conduction losses from the hot spot of a compressed target. This can lead to the ignition of massive shells imploded with low velocity-a way of reaching higher gains than is possible with conventional ICF.

# Skunk Works Reveals Compact Fusion Reactor Details

Oct 15, 2014
http://aviationweek.com/technology/skunk-works-reveals-compact-fusion-reactor-details

Lockheed Martin aims to develop compact reactor prototype in five years, production unit in 10

Hidden away in the secret depths of the Skunk Works, a Lockheed Martin research team has been working quietly on a nuclear energy concept they believe has the potential to meet, if not eventually decrease, the world’s insatiable demand for power.

Dubbed the compact fusion reactor (CFR), the device is conceptually safer, cleaner and more powerful than much larger, current nuclear systems that rely on fission, the process of splitting atoms to release energy. Crucially, by being “compact,” Lockheed believes its scalable concept will also be small and practical enough for applications ranging from interplanetary spacecraft and commercial ships to city power stations. It may even revive the concept of large, nuclear-powered aircraft that virtually never require refueling—ideas of which were largely abandoned more than 50 years ago because of the dangers and complexities involved with nuclear fission reactors. -

-To understand the breakthroughs of the Lockheed concept, it is useful to know how fusion works and how methods for controlling the reaction have a fundamental impact on both the amount of energy produced and the scale of the reactor. Fusion fuel, made up of hydrogen isotopes deuterium and tritium, starts as a gas injected into an evacuated containment vessel. Energy is added, usually by radio-frequency heating, and the gas breaks into ions and electrons, forming plasma.

The super hot plasma is controlled by strong magnetic fields that prevent it from touching the sides of the vessel and, if the confinement is sufficiently constrained, the ions overcome their mutual repulsion, collide and fuse. The process creates helium-4, freeing neutrons that carry the released energy kinetically through the confining magnetic fields. These neutrons heat the reactor wall which, through conventional heat exchangers, can then be used to drive turbine generators.

Until now, the majority of fusion reactor systems have used a plasma control device called a tokamak, invented in the 1950s by physicists in the Soviet Union. The tokamak uses a magnetic field to hold the plasma in the shape of a torus, or ring, and maintains the reaction by inducing a current inside the plasma itself with a second set of electromagnets. The challenge with this approach is that the resulting energy generated is almost the same as the amount required to maintain the self-sustaining fusion reaction.

An advanced fusion reactor version, the International Thermonuclear Experimental Reactor (ITER), being built in Cadarache, France, is expected to generate 500 MW. However, plasma is not due to be generated until the late 2020s, and derivatives are not likely to be producing significant power until at least the 2040s.

The problem with tokamaks is that “they can only hold so much plasma, and we call that the beta limit,” McGuire says. Measured as the ratio of plasma pressure to the magnetic pressure, the beta limit of the average tokamak is low, or about “5% or so of the confining pressure,” he says. Comparing the torus to a bicycle tire, McGuire adds, “if they put too much in, eventually their confining tire will fail and burst—so to operate safely, they don’t go too close to that.” Aside from this inefficiency, the physics of the tokamak dictate huge dimensions and massive cost. The ITER, for example, will cost an estimated 50 billion and when complete will measure around 100 ft. high and weigh 23,000 tons. ----------- # Scientists in Germany switch on nuclear fusion experiment (Update) ##### February 3, 2016 http://phys.org/news/2016-02-scientists-germany-nuclear-fusion.html Scientists in Germany flipped the switch Wednesday on an experiment they hope will advance the quest for nuclear fusion, considered a clean and safe form of nuclear power. Following nine years of construction and testing, researchers at the Max Planck Institute for Plasma Physics in Greifswald injected a tiny amount of hydrogen into a doughnut-shaped device—then zapped it with the equivalent of 6,000 microwave ovens. The resulting super-hot gas, known as plasma, lasted just a fraction of a second before cooling down again, long enough for scientists to confidently declare the start of their experiment a success. "Everything went well today," said Robert Wolf, a senior scientist involved with the project. "With a system as complex as this you have to make sure everything works perfectly and there's always a risk." Among the difficulties is how to cool the complex arrangement of magnets required to keep the plasma floating inside the device, Wolf said. Scientists looked closely at the hiccups experienced during the start-up of the Large Hadron Collider in Switzerland more than five years ago to avoid similar mistakes, he said. The experiment in Greifswald is part of a world-wide effort to harness nuclear fusion, a process in which atoms join at extremely high temperatures and release large amounts of energy that's similar to what occurs inside the sun. Advocates acknowledge that the technology is probably many decades away, but argue that—once achieved—it could replace fossil fuels and conventional nuclear fission reactors. Construction has already begun in southern France on ITER, a huge international research reactor that uses a strong electric current to trap plasma inside a doughnut-shaped device long enough for fusion to take place. The device, known as a tokamak, was conceived by Soviet physicists in the 1950s and is considered fairly easy to build, but extremely difficult to operate. The team in Greifswald, a port city on Germany's Baltic coast, is focused on a rival technology invented by the American physicist Lyman Spitzer in 1950. Called a stellarator, the device has the same doughnut shape as a tokamak but uses a complicated system of magnetic coils instead of a current to achieve the same result. -------------- # GPS Moonshots: Creating a star on earth December 22, 2014 http://www.cnn.com/videos/bestoftv/2014/12/22/exp-gps-moonshots-iter-sot.cnn -------------- The problem with trying to create a synthetic star with ITER, is trying to harness the immense heat, given off by the artificial miniature star. Scientists want to use magnetic energy, in order to trap the heat, given off by the synthetic star. This has many scientists concerned. The same types of theories were used, in trying to create an artificial black hole, while attempting to trap the energy, with different types of magnetic energy. --------- # ITER ITER (International Thermonuclear Experimental Reactor and Latin for "the way") is an international nuclear fusion research and engineering megaproject, which is currently building the world's largest experimental tokamak nuclear fusion reactor adjacent to the Cadarache facility in the south of France. The ITER project aims to make the long-awaited transition from experimental studies of plasma physics to full-scale electricity-producing fusion power plants. http://en.wikipedia.org/wiki/ITER ----------------- # Hydrogen-Boron vs. Deuterium-Tritium Nuclear fusion has the potential to generate power without the radioactive waste of nuclear fission, but that depends on which atoms you decide to fuse. Conventional fusion approaches work with deuterium and tritium (DT), while focus fusion works with hydrogen and boron eleven (pB11). http://focusfusion.org/index.php/site/article/deuterium_tritium_vs_hydrogen_boron/ -------------- We can even harness energy from different chemicals and gases, that can be made for self-sustaining sources of renewable energy. Scientists still question the footprint, that may be left, when using of combination of different chemicals, for a source of energy. ---------------------- # HOW IT WORKS: Fusion Power https://www.youtube.com/watch?v=LJZvFlo0iNs ----------------- # Small-scale nuclear fusion may be a new energy source September 25, 2015 Fusion energy may soon be used in small-scale power stations. This means producing environmentally friendly heating and electricity at a low cost from fuel found in water. Both heating generators and generators for electricity could be developed within a few years, according to new research. Nuclear fusion is a process whereby atomic nuclei melt together and release energy. Because of the low binding energy of the tiny atomic nuclei, energy can be released by combining two small nuclei with a heavier one. A collaboration between researchers at the University of Gothenburg and the University of Iceland has been to study a new type of nuclear fusion process. This produces almost no neutrons but instead fast, heavy electrons (muons), since it is based on nuclear reactions in ultra-dense heavy hydrogen (deuterium). http://www.sciencedaily.com/releases/2015/09/150925085550.htm ------------ ### Nuclear fusion, the ultimate clean energy 20th March, 2015 http://theforeigner.no/pages/columns/nuclear-fusion-the-ultimate-clean-energy/ ------------- Magnetic fields and lasers elicit graphene secret ##### Nov 24, 2014 Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have studied the dynamics of electrons from the "wonder material" graphene in a magnetic field for the first time. This led to the discovery of a seemingly paradoxical phenomenon in the material. Its understanding could make a new type of laser possible in the future. Together with researchers from Berlin, France, the Czech Republic and the United States, the scientists precisely described their observations in a model and have now published their findings in the scientific journal Nature Physics. Read more at: http://phys.org/news/2014-11-magnetic-fields-lasers-elicit-graphene.html#jCp http://phys.org/news/2014-11-magnetic-fields-lasers-elicit-graphene.html Graphene is considered a "wonder material": its breaking strength is higher than steel and it conducts electricity and heat more effectively than copper. As a two-dimensional structure consisting of only a single layer of carbon atoms, it is also flexible, nearly transparent and approximately one million times thinner than a sheet of paper. Furthermore, shortly after its discovery ten years ago, scientists recognized that the energy states of graphene in a magnetic field - known as Landau levels - behave differently than those of semiconductors. "Many fascinating effects have been discovered with graphene in magnetic fields, but the dynamics of electrons have never been studied in such a system until now," explains physicist Dr. Stephan Winnerl from HZDR. The HZDR researchers exposed the graphene to a four-Tesla magnetic field - forty times stronger than a horseshoe magnet. As a result, the electrons in graphene occupy only certain energy states. The negatively charged particles were virtually forced on tracks. These energy levels were then examined with free-electron laser light pulses at the HZDR. "The laser pulse excites the electrons into a certain Landau level. A temporally delayed pulse then probes how the system evolves," explains Martin Mittendorff, doctoral candidate at the HZDR and first author of the paper. Electron redistribution surprises scientists The result of the experiments has astonished the researchers. This particular energy level, into which new electrons were pumped using the laser, gradually emptied. Winnerl illustrates this paradoxical effect using an everyday example: "Imagine a librarian sorting books on a bookshelf with three shelves. She places one book at a time from the lower shelf onto the middle shelf. Her son is simultaneously 'helping' by taking two books from the middle shelf, placing one of them on the top shelf, the other on the bottom. The son is very eager and now the number of books on the middle shelf decreases even though this is precisely the shelf his mother wishes to fill." Because there were neither experiments nor theories regarding such dynamics before, the Dresden physicists initially had difficulty interpreting the signals correctly. After a number of attempts, however, they found an explanation: collisions between electrons cause this unusual rearrangement. "This effect has long been known as Auger scattering, but no one expected it would be so strong and would cause an energy level to become depleted," explains Winnerl. This new discovery could be used in the future for developing a laser that can produce light with arbitrarily adjustable wavelengths in the infrared and terahertz ranges. "Such a Landau-level laser was long considered impossible, but now with graphene this semiconductor physicists' dream could become a reality," says Winnerl enthusiastically. ------ # Magnetized target fusion Magnetized target fusion (MTF) is a relatively new approach to producing fusion power that combines features of magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) approaches. Like the magnetic approach, the fusion fuel is confined at lower density by magnetic fields while it is heated into a plasma. Like the inertial approach, fusion is initiated by rapidly squeezing the target to greatly increase fuel density and temperature. Although the resulting density is far lower than in traditional ICF, it is thought that the combination of longer confinement times and better heat retention will let MTF yield the same efficiencies, yet be far easier to build. The term magneto-inertial fusion (MIF) is similar, but encompasses a wider variety of arrangements. The two terms are often applied interchangeably to experiments. http://en.wikipedia.org/wiki/Magnetized_target_fusion ------- # Levitated dipole A levitated dipole is a nuclear fusion experiment using a solid superconducting torus which is magnetically levitated inside the reactor chamber. It is believed that such an apparatus could contain plasma more efficiently than other fusion reactor designs. The superconductor forms an axisymmetric magnetic field of a nature similar to Earth's or Jupiter's magnetospheres. The machine was run in a collaboration between MIT and Columbia University. The Levitated Dipole Experiment was funded by the US Department of Energy's Office of Fusion Energy, but funding for the LDX was ended in November 2011 to concentrate resources on Tokamak designs http://en.wikipedia.org/wiki/Levitated_dipole ----------------------- With lazers, magnetism, vacuums and sustainable energy, it is possible to make many new inventions. ----------------- # Plasma propulsion engine A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast to ion thruster engines, which generates thrust through extracting an ion current from plasma source, which is then accelerated to high velocities using grids/anodes. https://en.wikipedia.org/wiki/Plasma_propulsion_engine -------------------- For more information on magnets for harvesting energy, view the chapter "Magnetic energy." ------------------------------------------------ # Plasma research shows promise for future compact accelerators ##### December 22, 2015 A transformative breakthrough in controlling ion beams allows small-scale laser-plasma accelerators to deliver unprecedented power densities. That development offers benefits in a wide range of applications, including nuclear fusion experiments, cancer treatments, and security scans to detect smuggled nuclear materials. "In our research, plasma uses the energy stored in its electromagnetic fields to self-organize itself in such a way to reduce the energy-spread of the laser-plasma ion accelerator," said Sasikumar Palaniyappan of Los Alamos National Laboratory's Plasma Physics group. "In the past, most of the attempts to solve this problem required active plasma control, which is difficult." Laser-plasma accelerators shoot a high-energy laser into a cloud of plasma, releasing a beam of ions, or electrically charged particles, in a fraction of the distance required by conventional accelerators. The laser generates electromagnetic fields in the plasma. Using a computer simulation called Vector-Particle-In-Cell (VPIC), the Laboratory's team of physicists and computational scientists developed a scheme that enlists the electromagnetic fields so the beam essentially contains itself, reducing the energy spread, making the beam more efficient, and concentrating more energy on its target. http://phys.org/news/2015-12-plasma-future-compact.html ---------------------- # Researchers identify zebra-like stripes of plasma in a patch of space ##### July 14, 2015 Since the early 1970s, orbiting satellites have picked up on noise-like plasma waves very close to the Earth's magnetic field equator. This "equatorial noise," as it was then named, seemed to be an unruly mess of electric and magnetic fields oscillating at different frequencies in the form of plasma waves. Now a team from MIT, the University of California at Los Angeles, the University of Sheffield, and elsewhere has detected a remarkably orderly pattern amid the noise. http://phys.org/news/2015-07-zebra-like-stripes-plasma-patch-space.html ---------------- # In plasmonics, 'optical losses' could bring practical gain ##### January 26, 2016 What researchers had thought of as a barrier to developing advanced technologies based on the emerging field of plasmonics is now seen as a potential pathway to practical applications in areas from cancer therapy to nanomanufacturing. Plasmonic materials contain features, patterns or elements that enable unprecedented control of light by harnessing clouds of electrons called surface plasmons. It could allow the miniaturization of optical technologies, bringing advances such as nano-resolution imaging and computer chips that process and transmit data using light instead of electrons, representing a potential leap in performance. However, the development of advanced optical technologies using plasmonics has been hampered because components under development cause too much light to be lost and converted into heat. But now researchers are finding that this "loss-induced plasmonic heating" could be key to development of various advanced technologies, said Vladimir M. Shalaev, co-director of the new Purdue Quantum Center, scientific director of nanophotonics at the Birck Nanotechnology Center in the university's Discovery Park and a distinguished professor of electrical and computer engineering. http://phys.org/news/2016-01-plasmonics-optical-losses-gain.html -------------------- For more information on nuclear experiments, with particle accelerators, view Chapter : CERN ---------------------- ---------------- ---------------- Chapter 5: Cold fusion ---------------- ---------------- --------------------- ## Cold fusion reactor verified by third-party researchers, seems to have 1 million times the energy density of gasoline October 9, 2014 Andrea Rossi’s E-Cat — the device that purports to use cold fusion to generate massive amounts of cheap, green energy — has been verified by third-party researchers, according to a new 54-page report. The researchers observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, or “far more than can be obtained from any known chemical sources in the small reactor volume.” The researchers were also allowed to analyze the fuel before and after the 32-day run, noting that the isotopes in the spent fuel could only have been obtained by “nuclear reactions” — a conclusion that boggles the researchers: “… It is of course very hard to comprehend how these fusion processes can take place in the fuel compound at low energies.” http://www.extremetech.com/extreme/191754-cold-fusion-reactor-verified-by-third-party-researchers-seems-to-have-1-million-times-the-energy-density-of-gasoline -------------- # Focus Fusion: The Fastest Route to Cheap, Clean Energy https://www.youtube.com/watch?v=yhKB-VxJWpg 8:00 - Goldman Sachs funding ----------------- # Nuclear Fission vs. Nuclear Fusion http://chemwiki.ucdavis.edu/Physical_Chemistry/Nuclear_Chemistry/Fission_and_Fusion/Nuclear_Fission_vs_Nuclear_Fusion ---------------- # MIT Physicists Create Ultracold Molecules of 23Na40K June 10, 2015 (MIT researchers have successfully cooled a gas of sodium potassium (NaK) molecules to a temperature of 500 nanokelvin. In this artist’s illustration, the NaK molecule is represented with frozen spheres of ice merged together: the smaller sphere on the left represents a sodium atom, and the larger sphere on the right is a potassium atom.) http://scitechdaily.com/mit-physicists-create-ultracold-molecules-of-23na40k/ A team of physicists from MIT has successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins, creating ultracold molecules. The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic molecular behavior is normal at ambient temperatures. But scientists have long suspected that if temperatures were to plunge to near absolute zero, molecules would come to a screeching halt, ceasing their individual chaotic motion and behaving as one collective body. This more orderly molecular behavior would begin to form very strange, exotic states of matter — states that have never been observed in the physical world. Now experimental physicists at MIT have successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins — just a hair above absolute zero, and over a million times colder than interstellar space. The researchers found that the ultracold molecules were relatively long-lived and stable, resisting reactive collisions with other molecules. The molecules also exhibited very strong dipole moments — strong imbalances in electric charge within molecules that mediate magnet-like forces between molecules over large distances. ------- # Cold Atom Laboratory Chills Atoms to New Lows ## September 26, 2014 ## (Artist's concept of an atom chip for use by NASA's Cold Atom Laboratory (CAL) aboard the International Space Station. CAL will use lasers to cool atoms to ultracold temperatures.Image Credit: NASA) ## http://www.jpl.nasa.gov/news/news.php?feature=4312 ## Cold Atom Laboratory researchers used lasers to optically cool rubidium atoms to temperatures almost a million times colder than that of the depths of space. The atoms were then magnetically trapped, and radio waves were used to cool the atoms 100 times lower. The radiofrequency radiation acts like a knife, slicing away the hottest atoms from the trap so that only the coldest remain.The research is at the point where this process can reliably create a Bose-Einstein condensate in just seconds."This was a tremendous accomplishment for the CAL team. It confirms the fidelity of the instrument system design and provides us a facility to perform science and hardware verifications before we get to the space station," said CAL Project Manager Anita Sengupta of JPL.While so far, the Cold Atom Laboratory researchers have created Bose-Einstein condensates with rubidium atoms, eventually they will also add in potassium. The behavior of two condensates mixing together will be fascinating for physicists to observe, especially in space.Besides merely creating Bose-Einstein condensates, CAL provides a suite of tools to manipulate and probe these quantum gases in a variety of ways. It has a unique role as a facility for the atomic, molecular and optical physics community to study cold atomic physics in microgravity, said David Aveline of JPL, CAL ground testbed lead. ---------------------- ---------------- ---------------- Chapter 6: Dark Energy ---------------- ---------------- --------------------- - # Dark energy #### https://en.wikipedia.org/wiki/Dark_energy #### In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe. Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate. Assuming that the standard model of cosmology is correct, the best current measurements indicate that dark energy contributes 68.3% of the total energy in the observable universe; the mass-energy of dark matter and ordinary matter contribute 26.8% and 4.9%, respectively; and other components such as neutrinos and photons contribute a very small amount. Again on a mass–energy equivalence basis, the density of dark energy (6.91 × 10−27 kg/m3) is very low, much less than the density of ordinary matter or dark matter within galaxies. However, it comes to dominate the mass–energy of the universe because it is uniform across space. #### ---------------------- # Science Documentary - DARK MATTER / DARK ENERGY Full Universe documentary #### https://www.youtube.com/watch?v=v7YCW8rfUDw -------- # A dark matter bridge in our cosmic neighborhood ##### July 14, 2015 By using the best available data to monitor galactic traffic in our neighborhood, Noam Libeskind from the Leibniz Institute for Astrophysics Potsdam (AIP) and his collaborators have built a detailed map of how nearby galaxies move. In it they have discovered a bridge of dark matter stretching from our Local Group all the way to the Virgo cluster—a huge mass of some 2,000 galaxies roughly 50 million light-years away, that is bound on either side by vast bubbles completely devoid of galaxies. This bridge and these voids help us understand a 40 year old problem regarding the curious distribution of dwarf galaxies. http://phys.org/news/2015-07-dark-bridge-cosmic-neighborhood.html#jCp ------ Dark matter may not be completely dark at all April 15, 2015 New studies by astronomers are slowly throwing some light on dark matter, the invisible and mysterious stuff that scientists believe makes up much of the universe. For the first time, astronomers believe they've observed the interactions of dark matter via a factor other than the force of gravity. Dark matter's gravitational interactions with the parts of the universe that we can actually see are the only reason that we know it exists at all. Weirdly, it has seemed until now that dark matter has no other known interactions with anything in the universe, including itself. A recent study seemed to back up the notion that bits of dark matter appear to just drift through space, and not even interact with each other. However, new observations of the simultaneous collision of four galaxies in the galaxy cluster Abell 3827 – using the European Southern Observatory's Very Large Telescope (VLT) in Chile and a technique called "gravitational lensing" – seemed to show a "clump" of dark matter around one of the galaxies, lagging a bit behind that galaxy. This sort of lollygagging is something that scientists have predicted might be observable during collisions if dark matter were to interact with itself through some force other than gravity, even slightly. "We used to think that dark matter just sits around, minding its own business, except for its gravitational pull," said Richard Massey at Durham University, lead author of a paper on the study. "But if dark matter were being slowed down during this collision, it could be the first evidence for rich physics in the dark sector – the hidden Universe all around us." http://www.gizmag.com/dark-matter-not-completely-dark/37013/ ----------- New model suggests dark matter is made of electrically charged particles September 27, 2015 http://www.gizmag.com/stealth-dark-matter/39577/?li_source=LI&li_medium=default-widget Scientists at the Lawrence Livermore National Laboratory (LLNL) believe that dark matter may be composed of electrically charged particles that are bound by a yet-unknown force and have somehow managed to escape detection. The theory could be verified with the help of the Large Hadron Collider (LHC) particle accelerator. Dark matter makes up over 80 percent of the mass in our universe, but we know little about its nature. Astrophysicists know it must exist from its gravitational effects on large clusters of galaxies, but they have been unable to spot it because this elusive substance interacts weakly with both ordinary matter and itself. In fact, so little is known about dark matter that scientists are still speculating as to what it's even made of. Through a combination of computer simulations and theoretical results, researchers Pavlos Vranas and colleagues have now developed a "stealth dark matter" model that could help unravel the mystery of why dark matter behaves like it does, what particles make it up, and what force binds them. Crucially, the model offers assumptions that physicists should be able to test using CERN's Large Hadron Collider (LHC) particle accelerator. -------------- Dark matter hiding in stars may cause observable oscillations September 18, 2015 http://phys.org/news/2015-09-dark-stars-oscillations.html#jCp (Phys.org)—Dark matter has never been seen directly, but scientists know that something massive is out there due to its gravitational effects on visible matter. One explanation for how such a large amount of mass appears to be right in front of our eyes yet completely invisible by conventional means is that the dark matter is hiding in the centers of stars. In a new study, physicists have investigated the possibility that large amounts of hidden mass inside stars might be composed of extremely lightweight hypothetical particles called axions, which are a primary dark matter candidate. The scientists, Richard Brito at the University of Lisbon in Portugal; Vitor Cardoso at the University of Lisbon and the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada; and Hirotada Okawa at Kyoto University and Waseda University, both in Japan, have published their paper on dark matter in stars in a recent issue of Physical Review Letters. ------------ Milky Way's black hole shows signs of increased chatter September 23, 2015 Three orbiting X-ray space telescopes have detected an increased rate of X-ray flares from the usually quiet giant black hole at the center of our Milky Way galaxy after new long-term monitoring. Scientists are trying to learn whether this is normal behavior that was unnoticed due to limited monitoring, or these flares are triggered by the recent close passage of a mysterious, dusty object. http://phys.org/news/2015-09-milky-black-hole-chatter.html#jCp ------------- # Scalar field dark matter #### The universe may be accelerating, fueled perhaps by a cosmological constant or some other field possessing long range ‘repulsive’ effects. A model must predict the correct form for the large scale clustering spectrum, account for cosmic microwave background anisotropies on large and intermediate angular scales, and provide agreement with the luminosity distance relation obtained from observations of high redshiftsupernovae. The modeled evolution of the Universe includes a large amount of unknown matter in order to agree with such observations. This matter has two components cold dark matter and dark energy. Each contributes to the theory of the origination of galaxies and the expansion of the Universe. The Universe must have a critical density, a density not explained by baryonic matter (ordinary matter) alone. #### http://en.wikipedia.org/wiki/Scalar_field_dark_matter #### ------------------ PHYSICS Neutrinos understood Neutrinos—ghostly particles—change identity as they move through space. The three types or flavour of neutrinos—electron, muon and tau—morph into each other through a phenomenon called oscillation. Just like white light composed of red, green and blue shifts its tint as the proportions of each colour change, the type of a neutrino changes as their masses oscillate. Two of these oscillations have been quantified. Now, researchers have characterised the third one. The measurement makes possible new experiments that may help explain why the present universe is filled mostly with matter, and not equal parts of matter and antimatter as postulated by the Big Bang theory. http://www.downtoearth.org.in/content/science-and-technology-briefs-27 #### ----------------- # Lambda-CDM model The ΛCDM (Lambda cold dark matter) or Lambda-CDM model is a parametrization of the Big Bang cosmological model in which the Universe contains a cosmological constant, denoted by Lambda (Greek Λ), associated with dark energy, and cold dark matter (abbreviated CDM).

In fact, for every gram's worth of atoms in the universe, there is at least five times more invisible material called "dark matter". So far scientists have failed to detect it, despite spending decades searching. The reason we know it exists is because of the gravitational pull of galaxy clusters and other phenomena we observe. The matter we can see in a cluster isn't enough to hold it together by gravity alone, meaning some additional invisible or obscure matter must be present. But we have no idea what it is – it could be made up of new, yet undiscovered particles. There are four fundamental forces that a dark matter particle could interact with. There is the strong force that binds together the atomic nucleus; the weak force which governs the decay of particles such as radioactivity; an electromagnetic force that mediates the force between charged particles; and the gravitational force which governs gravitational interaction. To observe matter in space we need it to interact via the electromagnetic force, as this involves the release of light or other electromagnetic radiation that a telescope can register. http://phys.org/news/2015-12-machos-wimpsmeet-candidates-dark.html ---------------- # The XENON Dark Matter Project The XENON100 experiment has recently released results from the last run (2011-2012). These data were acquired over 224.6 days within a fiducial volume containing 34 kg of liquid xenon and with an ultra low electromagnetic background. After unblinding the region of interest, two events were observed, consistent with the total background expectation of (1.0 ± 0.2) events. A Profile Likelihood analysis of these data leads to the upper limit on the spin independent elastic WIMP-nucleon scattering cross section ( σSI), with a minimum of 2x 10-45 cm2 at 55 GeV/c2 and 90% confidence level, which are shown in the picture on the left, and corresponds to the present best experimental upper limit set on σSI. For comparison, the results from a selection of other experiments are also shown along with the most likely parameter space for a positive detection as predicted by the Constrained Minimal Supersymmetric Extension of the Standard Model (cMSSM) and in accordance with the latests results from the LHC.

Space scientists at the University of Leicester have detected a curious signal in the X-ray sky – one that provides a tantalising insight into the nature of mysterious Dark Matter. The Leicester team has found what appears to be a signature of 'axions', predicted 'Dark Matter' particle candidates – something that has been a puzzle to science for years. In a study being published on Monday 20 October in the Monthly Notices of the Royal Astronomical Society, the University of Leicester scientists describe their finding of a signal which has no conventional explanation. As first author Professor George Fraser, who sadly died in March of this year, wrote: "The direct detection of dark matter has preoccupied physics for over thirty years." Dark Matter, a kind of invisible mass of unknown origin, cannot be seen directly with telescopes, but is instead inferred from its gravitational effects on ordinary matter and on light. Dark Matter is believed to make up 85% of the matter of the Universe. "The X-ray background - the sky, after the bright X-ray sources are removed - appears to be unchanged whenever you look at it," explained Dr. Andy Read, also from the University of Leicester Department of Physics and Astronomy and now leading the paper. "However, we have discovered a seasonal signal in this X-ray background, which has no conventional explanation, but is consistent with the discovery of axions." This result was found through an extensive study of almost the entire archive of data from the European Space Agency's X-ray observatory, XMM-Newton, which will celebrate its 15th year in orbit this December. Previous searches for axions, notably at CERN, and with other spacecraft in Earth orbit, have so far proved unsuccessful. As Professor Fraser explains in the paper: "It appears plausible that axions – Dark Matter particle candidates - are indeed produced in the core of the Sun and do indeed convert to X-rays in the magnetic field of the Earth." It is predicted that the X-ray signal due to axions will be greatest when looking through the sunward side of the magnetic field because this is where the field is strongest. Dr. Read concludes: "These exciting discoveries, in George's final paper, could be truly ground-breaking, potentially opening a window to new physics, and could have huge implications, not only for our understanding of the true X-ray sky, but also for identifying the Dark Matter that dominates the mass content of the cosmos." President of the Royal Astronomical Society Professor Martin Barstow, who is Pro-Vice-Chancellor, Head of the College of Science & Engineering and Professor of Astrophysics & Space Science at the University of Leicester said: "This is an amazing result. If confirmed, it will be first direct detection and identification of the elusive dark matter particles and will have a fundamental impact on our theories of the Universe." http://phys.org/news/2014-10-inexplicable-tantalising-clue-dark.html#jCp ------ # Dark 'noodles' may lurk in the Milky Way ##### January 21, 2016 Invisible structures shaped like noodles, lasagne sheets or hazelnuts could be floating around in our Galaxy radically challenging our understanding of gas conditions in the Milky Way... http://phys.org/news/2016-01-dark-noodles-lurk-milky.html?utm_source=menu&utm_medium=link&utm_campaign=item-menu --------------------- # Study finds possible alternative explanation for dark energy ##### December 30, 2014 http://phys.org/news/2014-12-alternative-explanation-dark-energy.html ------------------- ---------------- ---------------- Chapter 7: Batteries & energy storage ---------------- ---------------- --------------------- The following chapter will detail some of the new technology that has been introduced in battery technology, including energy storage. ------------ # Wood nanobattery could be green option for large-scale energy storage July 6, 2013 (A closeup of the wood fibers used by the researchers in their sodium-ion battery (Image: University of Maryland) Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new "wood battery" could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage. http://www.gizmag.com/wood-battery-energy-storage/28032/ --------- # Trees are source for high-capacity, soft batteries ##### Jun 01, 2015 ##### ( A closeup of the soft battery, created with wood pulp nanocellulose.) http://phys.org/news/2015-06-trees-source-high-capacity-soft-batteries.html?utm_source=menu&utm_medium=link&utm_campaign=item-menu A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers in Sweden and the US. Using nanocellulose broken down from tree fibres, a team from KTH Royal Institute of Technology and Stanford University produced an elastic, foam-like battery material that can withstand shock and stress. "It is possible to make incredible materials from trees and cellulose," says Max Hamedi, who is a researcher at KTH and Harvard University. One benefit of the new wood-based aerogel material is that it can be used for three-dimensional structures. "There are limits to how thin a battery can be, but that becomes less relevant in 3D, " Hamedi says. "We are no longer restricted to two dimensions. We can build in three dimensions, enabling us to fit more electronics in a smaller space." ------------------------- # Biodegradable computer chips made almost entirely from wood May 28, 2015 http://www.gizmag.com/biodegradable-wooden-computer-chips/37755/ --------------------- # You'll never be-leaf what makes up this battery ##### January 28, 2016 Scientists at the University of Maryland have a new recipe for batteries: Bake a leaf, and add sodium.

Photonic crystals are optical nanostructures that are tuned to specific wavelengths of light. If you understand how semiconductors affect the motion of electrons (i.e. the bandgap only allows electrons with a certain energy level to pass through), photonic crystals are the optical equivalent. In this case, MIT has created infrared-absorbing photonic crystals using metals such as tungsten and titanium. Because of their metallic roots, these photonic crystals can operate at temperatures up to 1200C (2192F). http://www.extremetech.com/extreme/116853-mits-photonic-crystals-lead-towards-a-nuclear-reactor-in-every-gadget ------- ## Tin nanocrystals for the battery of the future Published: 08.04.13 (Monodisperse tin nanodroplets in an electron microscopic image.)

"Our findings have demonstrated that renewable pollens could produce carbon architectures for anode applications in energy storage devices," said Vilas Pol, an associate professor in the School of Chemical Engineering and the School of Materials Engineering at Purdue University. Batteries have two electrodes, called an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite. Lithium ions are contained in a liquid called an electrolyte, and these ions are stored in the anode during recharging. The researchers tested bee pollen- and cattail pollen-derived carbons as anodes. "Both are abundantly available," said Pol, who worked with doctoral student Jialiang Tang. "The bottom line here is we want to learn something from nature that could be useful in creating better batteries with renewable feedstock." Research findings are detailed in a paper that appeared on Feb. 5 in Nature's Scientific Reports. Whereas bee pollen is a mixture of different pollen types collected by honey bees, the cattail pollens all have the same shape. "I started looking into pollens when my mom told me she had developed pollen allergy symptoms about two years ago," Tang said. "I was fascinated by the beauty and diversity of pollen microstructures. But the idea of using them as battery anodes did not really kick in until I started working on battery research and learned more about carbonization of biomass." The researchers processed the pollen under high temperatures in a chamber containing argon gas using a procedure called pyrolysis, yielding pure carbon in the original shape of the pollen particles. They were further processed, or "activated," by heating at lower temperature - about 300 degrees Celsius - in the presence of oxygen, forming pores in the carbon structures to increase their energy-storage capacity. http://phys.org/news/2016-02-allergens-anodes-pollen-derived-battery.html?utm_source=menu&utm_medium=link&utm_campaign=item-menu ------------- # New alloy claimed to have higher strength-to-weight ratio than any other metal December 11, 2014 When it comes to metal that's being used in the automotive or aerospace industries, the higher its strength-to-weight ratio, the better. With that in mind, researchers from North Carolina State University and Qatar University have developed a new alloy that reportedly has a low density similar to that of aluminum, but that's stronger than titanium. The material is a type of high-entropy alloy, meaning that it's made up of at least five metals in more or less equal amounts. In this case, those metals are lithium, magnesium, titanium, aluminum and scandium. "It has a combination of high strength and low density that is, as far as we can tell, unmatched by any other metallic material," said NCSU's Dr. Carl Koch, senior author of a paper on the research. "The strength-to-weight ratio is comparable to some ceramics, but we think it’s tougher – less brittle – than ceramics." He additionally informed us that while carbon fiber very likely has a higher strength-to-weight ratio than the alloy, it also wouldn't be as tough – in other words, the alloy would be more likely to bend under an amount of stress that would cause the carbon to fracture. More work still has to be done in the testing of the alloy, along with establishing a practical production method. Koch and his colleagues are also looking into replacing or eliminating the scandium that makes up 20 percent of the material, as it's very expensive. http://www.gizmag.com/high-entropy-alloy-strength-to-weight/35170/ --------------- # Graphene-Boron Compound Could Revolutionize Lithium-Ion Battery Capacity # May 28, 2013 http://www.greenoptimistic.com/graphene-boron-compound-could-revolutionize-lithium-ion-battery-capacity-20130528/#.VSFr-eG-2zk Researchers have touted graphene as a game-changing material that could boost the power and energy capacity of a lithium-ion battery. Graphene, a film of carbon atoms just one atom thick, is an excellent conductor of electricity. In a battery, the massive surface area of such carbon sheets could be a boon to increasing the power capacity of a lithium-ion battery. The only problem is lithium ions won’t bond with graphene, which makes it practically useless in a battery. While pure graphene didn’t seem to be a good option, researchers turned to imperfect graphene, that is, carbon mixed with other elements. Testing with boron, researchers at Rice University found the material to be about twice that of the standard graphite currently used in lithium-ion batteries. The new material is also more stable and doesn’t expand and contract as much as graphite alone. ------------------ # CALMAC Stores Surplus Wind Energy in Ice Banks ------------------------------- # Utah-Based Company Digging Underground Compressed Air Batteries http://www.greenoptimistic.com/utah-underground-energy-storage-20100209/#.VSHcl-G-2zk --------------------- # An All-Liquid Battery For Storing Solar And Wind Energy September 22, 2014 (This room-temperature liquid battery was made with mercury, salt water, and steel foam.

In particular, the new battery has a working voltage similar to that of a lithium-ion battery, a power density comparable to that of a supercapacitor, and it can maintain its good performance even when being charged and discharged at very high rates. The researchers, led by Assistant Professor Guihua Yu, along with Yu Ding and Yu Zhao, at UT Austin, have published their paper on the new membrane-free, semiliquid battery in a recent issue of Nano Letters. The researchers explain that the battery is considered "semiliquid" because it uses a liquid ferrocene electrolyte, a liquid cathode, and a solid lithium anode. ------------------------------- # Flexible and Safe Aluminum-Graphite Battery Charges in One Minute -------------------- # "Origami battery" made from paper and dirty water for just a few cents By June 13, 2015 A foldable, inexpensive paper battery that can generate a small amount of electricity brings a new sense of power to origami, the Japanese art of paper folding.

Certainly, much of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but some is left to accumulate on stockpiles which are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could one day be put to use thanks to a new chemical process that uses sulfur to make polymers. The new material could lead to a new generation of lighter, more efficient lithium-sulfur batteries, the researchers claim. ------------ # CaO makes the graphene hierarchy for high-power lithium-sulfur batteries ##### January 26, 2016 Structural hierarchy is the cornerstone of the biological world, as well as the most important lesson that we have learned from nature to develop ingenious hierarchical porous materials for various applications in energy conversion and storage. Recently, a research group from China, led by Prof. Qiang Zhang in Tsinghua University, has developed a novel kind of hierarchical porous graphene (HPG) via a versatile chemical vapor deposition (CVD) on CaO templates for high-power lithium-sulfur (Li-S) batteries.

This new portable battery could replace the batteries used in hearing aids, due to its reduced dimensions (measuring about less than a third of an inch). According to the researchers, in the near future it can replace laptop batteries as we known them, allowing them to run for hundreds of hours on a single charge. The small devices could benefit of this technology within a couple of years. “This would take about 10 years more and be revolutionary,” said Ein-Eli. The current prototypes of the battery have a silicon power source that reverts back to their original form as sand. “In the paper, we showed that at 600 hours it had used only 10 percent of the energy. So we are talking about 6,000 hours,” says the professor. http://www.greenoptimistic.com/ein-elis-new-battery-could-power-a-laptop-for-hundreds-of-hours-20091201/#.VSF4ceG-2zk ---------------- # Commercially-available NanoTritium battery can power microelectronics for 20+ years August 15, 2012 When installing micro-electronic devices in locations that are expensive or hard to reach, or just downright dangerous, you don't want to have to keep returning to swap out a battery cell.

The strongest, thinnest, and initially known as impermeable material, in fact allows hydrogen protons to pass through. No wonder graphene is labelled as the “miracle material”. Every property or use of it that is discovered, opens up a great deal of new and super exciting opportunities and applications. Of course, there is no one, who better understands graphene than its discoverer- the Nobel prize winner Andre Geim of University of Manchester, and therefore it is no surprise that exactly his team has found yet another super exciting property of the thin super-strong material. In the study published this week in the journal Nature, the team describes how at high temperatures, above 250 degrees Celsius, graphene allows hydrogen protons to pass through. In addition, this process of proton transport can be enhanced by adding an extra layer of catalytic metal nanoparticles, such as platinum. This great discovery has a potential in improving the performance of fuel cells. Here, it could act as a proton-conducting membrane, which could potentially eliminate the pressing problem of fuel leaks, associated with reduction of cell efficiency. This property also opens up new horizons for development of exciting hydrogen-based technologies. http://www.greenoptimistic.com/newly-discovered-property-graphene-boost-fuel-cells-efficiency-20141128/#.VSFr4OG-2zk ------------- # New electrolyte promises to rid lithium batteries of short-circuiting dendrites March 2, 2015 (Scanning electron microscope images that show how normal electrolyte promotes dendrite growth (a, left), while PNNL’s new electrolyte produces smooth nodules that don’t short-circuit cells (b, right).

Dr. Elena Polyakova and Dr. Daniel Stolyarov, originally from Russia, founded Graphene 3D Lab and have since moved the company to Calverton, New York. They spent more than five years researching raw materials that can be used to make a graphene battery using a 3D printer. Graphene is a special form of carbon in which the atoms are arranged in a hexagonal lattice along a single layer. In this configuration, the carbon is 200 times stronger than steel and it conducts electricity 30 times faster than silicon. It is the latter feature that makes it ideal for making tough composites, computer chips and well, batteries. Already batteries with lives 25 percent longer than lithium-ion batteries have already been made by other researchers. Graphene 3D Lab’s design has one up on the competition, however, because it can be made anywhere and practically in any shape. Although the prototype is able to produce the same amount of power as a common AA battery, it has already produced considerable interest from the military, as well as from the aerospace and car industries, according to Dr. Polyakova, Graphene 3D Lab’s CoO. The company’s technology allows one to print batteries to fit crooks and nannies where space is tight. It can be used to print other graphene parts. As such, this technology is very useful for space missions. Dr. Polyakova says, “That is an exotic example, but a good one. A mission of that kind requires thousands of spare parts and dozens of different battery types. Our technology could remove the need to carry replacement batteries.” --------------- # Looking at graphene and other 2d crystals in energy conversion and storage 3 February 2015 http://graphene-flagship.eu/?news=looking-at-graphene-and-other-2d-crystals-in-energy-conversion-and-storage -------------- Scientists see the light on microsupercapacitors: Laser-induced graphene makes simple, powerful energy storage possible December 3, 2015 Rice University researchers who pioneered the development of laser-induced graphene have configured their discovery into flexible, solid-state microsupercapacitors that rival the best available for energy storage and delivery. http://phys.org/news/2015-12-scientists-microsupercapacitors.html --------------- # Long-sought chiral anomaly detected in crystalline material ##### September 3, 2015 A study by Princeton researchers presents evidence for a long-sought phenomenon—first theorized in the 1960s and predicted to be found in crystals in 1983—called the "chiral anomaly" in a metallic compound of sodium and bismuth.

The surfaces could provide a way to culture cells in the lab that better approximates the complex environments in which cells grow in the body. http://phys.org/news/2015-04-wrinkle-cell-culture.html?utm_source=menu&utm_medium=link&utm_campaign=item-menu -------------------- # Renewable energy from evaporating water (w/ Video) ##### June 16, 2015 ##### (The "moisture mill" is a new kind of turbine engine that turns continuously as water evaporates from the wet paper lining the walls of the engine.) An immensely powerful yet invisible force pulls water from the earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential to propel self-sufficient devices or produce electricity has remained largely untapped—until now. In the June 16 online issue of Nature Communications, Columbia University scientists report the development of two novel devices that derive power directly from evaporation - a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car. http://phys.org/news/2015-06-renewable-energy-evaporating-video.html --------------------- # World's first "aqueous solar flow battery" outperforms traditional lithium-iodine batteries August 3, 2015 The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent. It was last October that researchers at Ohio State University (OSU) first detailed their patent-pending design for a dye-sensitized solar cell also capable of storing its own power. With three electrodes rather than the typical four, it featured a lithium plate base, two layers of electrode separated by a thin sheet of porous carbon, and a titanium gauze mesh that played host to a dye-sensitive titanium dioxide photoelectrode. The reasoning behind the porous nature of the materials was to allow the battery's ions to oxidize into lithium peroxide, which was in turn chemically decomposed into lithium ions and stored as lithium metal. But the team has redesigned the battery so that air no longer needs to pass through it in order to function. http://www.gizmag.com/aqueous-solar-flow-battery-osu/38748/?li_source=LI&li_medium=default-widget ----------------------- ---------------- ---------------- Chapter 8: Magnetic energy ---------------- ---------------- --------------------- # Magnetic energy https://en.wikipedia.org/wiki/Magnetic_energy Magnetic energy and electric energy are related by Maxwell's equations.

Energy harvesters provide a very small amount of power for low-energy electronics. While the input fuel to some large-scale generation costs money (oil, coal, etc.), the energy source for energy harvesters is present as ambient background and is free. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment because of radio and television broadcasting. ### Piezoelectric The piezoelectric effect converts mechanical strain into electric current or voltage. This strain can come from many different sources. Human motion, low-frequency seismic vibrations, and acoustic noise are everyday examples. Except in rare instances the piezoelectric effect operates in AC requiring time-varying inputs at mechanical resonance to be efficient. Most piezoelectric electricity sources produce power on the order of milliwatts, too small for system application, but enough for hand-held devices such as some commercially available self-winding wristwatches. One proposal is that they are used for micro-scale devices, such as in a device harvesting micro-hydraulic energy. In this device, the flow of pressurized hydraulic fluid drives a reciprocating piston supported by three piezoelectric elements which convert the pressure fluctuations into an alternating current. ------------------------- # Preparation on transparent flexible piezoelectric energy harvester based on PZT films by laser lift-off process # http://www.sciencedirect.com/science/article/pii/S0924424712006516 The piezoelectric energy generation properties of transparent flexible devices (TFD) based on PbZr0.52Ti0.48O3 (PZT) films, which were fabricated by laser lift-off (LLO) process, were studied for a piezoelectric energy harvester. Through the introduction of indium-tin-oxide (ITO) and polyethylene terephthalate (PET) substrates, TFDs were implemented, respectively. The TFDs based on PZT films generated an AC-type output signal and output power of 8.4 nW/cm2, at periodically bending and releasing motion. In addition, inverted output signals were observed when the manufactured TFDs were connected to the measuring equipment in reverse and were bended to the reverse direction, demonstrating that the generating signals originated from the piezoelectric effect of TFDs. The experimental results clearly showed that the TFDs based PZT film have potential for use in next generation of electronic devices applications such as flexible devices, transparent electronics, and energy harvester. ---------------- # Scientists use shape-fixing nanoreactor to make a better fuel cell catalyst ##### May 11, 2015 http://phys.org/news/2015-05-scientists-shape-fixing-nanoreactor-fuel-cell.html?utm_source=menu&utm_medium=link&utm_campaign=item-menu --------------------- # Laser-machined piezoelectric cantilevers for mechanical energy harvesting In this study, we report results on a piezoelectric- material-based mechanical energy-harvesting device that was fabricated by combining laser machining with microelectronics packaging technology.

Their principles and advantages as sensor platforms are discussed along with the materials selection. A detailed and complete comparison between the MSMC and MSP is given. It is concluded that for the resonators with the same size, an MSP exhibits a higher sensitivity and has a much higher resonant frequency. For the resonators with the same resonant frequency, MSMCs exhibit a much higher sensitivity and have a much smaller size than MSPs. Using antibody as the sensing element, MSP biosensors for in situ detection of Escherichia coli and Listeria monocytogenes are developed and characterized. These biosensors exhibit a high performance. For example, the MSP-antibody biosensors of 1 mm × 0.3 mm × 15 μm exhibit a detection limit less than 100 cfu/ml for in situ detection of bacterial cell in water. A new type actuator is introduced using MSPs. The MSP actuator is operated using AC magnetic field with a frequency close to, but different than, its resonant frequency. The MSP actuator exhibits an unlimited displacement, and its moving direction is controlled by the operating frequency used. -------------- # Levitating Magnet May Yield New Approach to Clean Energy # http://engineering.columbia.edu/levitating-magnet-may-yield-new-approach-clean-energy Achieving nuclear fusion in the laboratory has been a cherished goal of physicists and energy researchers for more than 50 years.

Such infections can be caused by a number of bacteria that gain entrance into your body via cuts, scrapes, bites or open wounds. Even bacteria that normally live on your skin can cause an infection when introduced into your body this way. Skin and soft tissue infections account for more than 14 million hospital visits each year, costing the health care system an estimated24 billion.
Unfortunately, many infections are becoming increasingly difficult to treat. Antibiotic overuse has led to the emergence of antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus, also known as MRSA.
Finding effective countermeasures to this growing public health threat has turned out few options, but the remedy may be as simple as colored light.
According to a new proof-of-principle study,1 blue light can selectively eliminate infections caused by Pseudomonas aeruginosa. According to lead researcher Michael R. Hamblin of the Massachusetts General Hospital:2
"Microbes replicate very rapidly, and a mutation that helps a microbe survive in the presence of an antibiotic drug will quickly predominate throughout the microbial population. Recently, a dangerous new enzyme, NDM-1, that makes some bacteria resistant to almost all antibiotics available has been found in the United States. Many physicians are concerned that several infections soon may be untreatable.
Blue light is a potential non-toxic, non-antibiotic approach for treating skin and soft tissue infections, especially those caused by antibiotic resistant pathogens."

## Could Blue Light Replace Antibiotics?

In the study, lab animals were infected with P. aeruginosa. Incredibly, ALL of the animals treated with blue light survived, while 82 percent of the controls died. Could this possibly be the beginning of a whole new treatment paradigm for infections? Clearly, we’re nearing the end of the road of the antibiotic era, as antibiotic-resistance spreads.
Blue light therapy has also been shown to be effective against MRSA and other resistant bugs, offering new hope for effective treatments.
In a previous study published in 2009,3 over 90 percent of community acquired and hospital acquired strains of MRSA were successfully eradicated within mere minutes of exposure to blue light. According to the authors:

# In plasmonics, 'optical losses' could bring practical gain

##### January 26, 2016

What researchers had thought of as a barrier to developing advanced technologies based on the emerging field of plasmonics is now seen as a potential pathway to practical applications in areas from cancer therapy to nanomanufacturing.

Plasmonic materials contain features, patterns or elements that enable unprecedented control of light by harnessing clouds of electrons called surface plasmons. It could allow the miniaturization of optical technologies, bringing advances such as nano-resolution imaging and computer chips that process and transmit data using light instead of electrons, representing a potential leap in performance.

However, the development of advanced optical technologies using plasmonics has been hampered because components under development cause too much light to be lost and converted into heat. But now researchers are finding that this "loss-induced plasmonic heating" could be key to development of various advanced technologies, said Vladimir M. Shalaev, co-director of the new Purdue Quantum Center, scientific director of nanophotonics at the Birck Nanotechnology Center in the university's Discovery Park and a distinguished professor of electrical and computer engineering.

# Low level laser therapy

Low-level laser therapy (LLLT) is a form of laser medicine used in physical therapy and veterinary treatment that uses low-level (low-power) lasers or light-emitting diodes to alter cellular function. Other names for the therapy include low-power laser, soft laser, cold laser, biostimulation laser, therapeutic laser, and laser acupuncture.[1] Whereas high-power lasers ablate tissue, low-power lasers are claimed to stimulate it and to encourage the cells to function.

Laser therapy works in a number of ways to heal injuries and manage pain. Among them:
• It increases the release of endorphins (natural painkillers).
• Laser therapy decreases inflammation, which helps return tissue to a normal state.
• It restores metabolic function.

---------------------

# History of Cold Laser Therapy

http://www.spine-health.com/treatment/pain-management/history-cold-laser-therapy

Cold Laser Therapy has been used in clinical practice all around the world for over four decades. In 1916, Albert Einstein conceived the theory of Light Amplification through Stimulated Emission of Radiation or LASER. In 1967, Professor Andre Mester began using low power lasers in medicine. Dr. Mester is recognized by many as the grandfather of laser therapy.

The first experimental FDA clearance of Class 3B Lasers occurred in February of 2002, after a successful study for carpal tunnel syndrome on workers at General Motors. The laser that was used had a power of 90mw at 830nm.
Certain low level laser devices are also FDA approved for relief of the following conditions3,4:
• Muscle and joint pain
• Stiffness associated with arthritis
• Pain associated with muscle spasms
• Hand pain and wrist pain associated with Carpal Tunnel Syndrome
• Neck pain
• Lower back pain
• Wound healing

# Discover the Benefits of K-Laser Class 4 Laser Therapy Treatments

## What You Need to Know About Lasers

Lasers are classified according to their power output:
• Class 3a—maximum of 5 milliwatts of power (standard laser pointer)
• Class 3b—maximum of 500 milliwatts/0.5 watts
• Class 4—anything over 500 milliwatts/0.5 watts
The most significant issue with the clinical use of lasers is the depth of penetration. Some practitioners make the mistake of using low-power Class 3 lasers, which basically amounts to a standard laser pointer.
Most class 3a lasers only use a red wavelength – 635 nanometers in the visible red. When you look at the depth of penetration with laser, red laser light only penetrates about one to two millimeters (far less than 1/8 inch) into the human body.
Granted, red laser is highly useful for treating superficial wounds, cuts, abrasions, and perhaps even for the treatment of vitiligo, but they will not penetrate far enough for deep seated pain reduction. However, infrared lasers (around 800 nanometers) penetrate far deeper and able to go several centimeters, into your body which will reach most tissue injuries.
Power is also another crucial factor when it comes to laser therapy. Power is measured in watts, and you can think of it as the brightness of the light. A higher-powered laser is a brighter light, and it can produce more energy per unit of time. When it comes to doing laser therapy treatment, a higher-powered laser (Class 4) provides two benefits:
• A therapeutic dose of laser light can be applied to a much larger volume of tissue
• By shining that brighter light at the surface, photons of light are able to penetrate deeper into the tissues, which allows you to treat deep-seated pain conditions

Paintballs to deflect killer-asteroids

Mar 07, 2013
Having reviewed these traditional asteroid deflection techniques, Sung Wook Paek, a graduate from the Massachusetts Institute of Technology, suggests an unusual alternative: Mr Paek proposes using paintballs to pull an asteroid off course.

The argument behind Mr Paek's idea is reasonably simple; after measuring the velocity and rotation of an incoming asteroid, two unmanned spacecraft would approach the celestial body close enough to be able to shoot large clouds of white paintballs at it! Two probes would be needed because, as the asteroid rotates, a shot from only one spacecraft would not cover the entire asteroid with white paint and so the first probe strikes one side of the asteroid, the second probe covers the other.

The white paint would reflect light and other electromagnetic radiation from the asteroid's surface, and, over time, the cumulative effect of billions of photons would result in the asteroid changing course. The white paint would effectively act as a 'solar sail', increasing the balance of solar radiation absorbed and emitted by the asteroid, gently easing it away from its original destination.
Another deflection technique, also based on light reflectivity or laser sublimation was proposed by a team of American researchers who suggested launching a swarm of 'mirror bees' towards the potential killer.

Tiny probes, equipped with mirrors, would position themselves in such a way as to reflect a concentration of sunlight on one specific point of the asteroid. This 'beam of light' would then generate enough heat for it to start to vaporise, creating propulsive gas jets. In essence, vapour emitted from the asteroid would push it off-course. Alternatively, the asteroid might 'simply' be wrapped in reflective 'foil'.

# Laser Bees

A New Way to Deflect a Dangerous Asteroid
What do we do if an asteroid is found to be on a collision course with Earth? At this point, the answer is not clear, so The Planetary Society has partnered with researchers to discover ways to protect Earth when we one-day find a dangerous space rock.

We've been working with a team at the University of Strathclyde and the University of Glasgow in Scotland to study a new technique which uses concentrated light to gently move an asteroid -- a project we called "Mirror Bees" -- using mirrors on several spacecraft swarming around an asteroid to focus sunlight onto a spot on the asteroid. As part of the initial Mirror Bees project, researchers found that lasers are more effective than mirrors and can be used from greater distances. So, now the project is called "Laser Bees."

# Physicist unveils plan for entangling massive objects

##### August 5, 2015
Schnabel's plan is to place two of the mirrors in a Michelson-type interferometer in such a way as to have both sides of both mirrors hit by light that is sent in. The mirrors would also be placed in the interferometer in a way that would allow them to oscillate when struck by the light. This would allow for momentum to be transferred between the mirrors and the light. The mirror oscillations would then have an impact on the phase of the reflected light, causing the momentum and the light to become entangled. At that point, the entanglement could be "swapped" to the mirrors, causing them to be entangled, by measuring the light beams as they exit.

Asteroid Impact Avoidance

July 2013

DE-STAR is designed to vaporize or divert asteroids that threaten Earth. This isn't science fiction—I build things that have to work in practice. DE-STAR stands for Directed Energy Solar Targeting of Asteroids and exploRation. It looks like an open matchbook with lasers on one flap and a photovoltaic panel for power from sunlight on the other. By synchronizing the laser beams, we can create a phased array, which produces a steerable 70-gigawatt beam. An onboard system receives orders on what to target. Our laser beam would then produce a spot about 100 feet in diameter on an asteroid that's as far away from the satellite as we are from the sun. The laser would raise an asteroid's surface temperature to thousands of degrees Celsius—hot enough that all known substances evaporate. In less than an hour, DE-STAR could have completely vaporized the asteroid that broke up over Russia this winter, if we had seen it coming. Plus, as the material evaporates, it creates a thrust in the opposite direction, comparable to the space shuttle's rocket booster. That means you could divert the asteroid by changing its orbit with a shorter laser blast.
DE-STAR could also power things on Earth or in space. You could send the electrical power it produces—not via laser beam but via microwaves. Or you could use the laser to directly propel spacecraft. But here's the thing: For full-blown asteroid vaporization, each flap of the matchbook would have to be six miles long. We've never built a structure this size in space, but if there were the worldwide will, I could see building this within 30 to 50 years. But since it's completely modular, we propose starting smaller. We could begin with a version that's three feet per side right now. With that, you could cook your dinner from 600 miles away.

# Physicists demonstrate conditions for laser-driven fusion

##### March 15, 2011
Currently, commercial nuclear power plants generate electricity using nuclear fission, in which an atom’s nucleus is split into lighter nuclei. But scientists are also researching the reverse reaction, nuclear fusion, in which two light atomic nuclei fuse to form a single heavier nucleus. Compared with fission, fusion has the potential to produce less radioactive waste while still generating large amounts of energy.

The following will discuss Lazers as weapons, including the use of lazers, being used for weather modification. Companies such as DuPont, and Boeing, want to make lazers, for the use in the war industry. The people need to be cautious, of giving too much technological power, to one group of people. Often, we can see how new technology, can be abused in warfare, and on the environment as well.

# Electric Laser Race Heats Up

http://sites.psu.edu/thebigbangtheory/2012/10/29/the-holographic-excitation/

Not wanting to be left out of the race to field compact battlefield lasers, Boeing announced yesterday that it’s tested its own solid-state laser technology. "In each laser firing at Boeing’s facility in West Hills, Calif., the high-energy laser achieved power levels of over 25 kilowatts for multi-second durations, with a measured beam quality suitable for a tactical weapon system," says Boeing.
What’s interesting about this announcement is that Boeing is not part of the Defense Department’s Joint High-Powered Solid State Laser, a program that has funded Northrop Grumman and Textron to build a deployable laser weapon. Boeing at one point teamed with the Livermore lab on a solid-state work, but that laser, which was powerful but large, was not selected by the program for funding. Similarly, Raytheon also has a solid state laser that was passed over for funding. Both Livermore and Raytheon have continued their solid-state laser work on their own dime, however. Boeing, until this point, did not appear to be that active on solid-state lasers, and it appears this new effort is self-funded.

# Lockheed Martin begins manufacturing vehicle-mounted laser weapon

October 8, 2015

Lockheed Martin announced this week that production of a new laser weapon system has begun at the company's Bothell, Washington facility. The high-powered laser weapon modules will be used as the heart of a 60-kilowatt system designed to be fitted to a US Army vehicle.

The laser can be operated by a single person and is made up of multiple fiber laser modules, which not only allows for greater flexibility, but also lessens the chance of the weapon being knocked out by a minor malfunction, so frequent repairs aren't required. Lockheed Martin also says that the modular design means that the laser power can be varied across an extremely wide range to suit specific mission needs. Using off-the-shelf commercial fiber laser components to keep down costs, the modules can be linked together to produce lasers of up to 120 kW.

# Shooting lightning out of the sky

## New methods to make longer streams of plasma with greater longevity could lead to laser-powered lightning rods

Date:
September 24, 2015
A team of researchers has demonstrated new techniques that bring lasers as lighting rods closer to reality. When a powerful laser beam shoots through the air, it ionizes the molecules, leaving a thin trail of hot, ionized particles in its wake. Because this stream of plasma conducts electricity, it could be used to channel away a potentially damaging lightning bolt. The researchers found ways to make the length of such a plasma channel reach more than 10 times longer -- a necessary advance for using the channel to redirect a lightning strike.

Connecting the Raytheon, AMS, Lockheed, HAARP, NOAA, General Dynamics and DARPA dots….

Defense Advanced Research Program Association, or DARPA, has contracted co-operation command of the Highly Active Auroral Research Program (HAARP) electromagnetic microwave ionospheric heater in Gakona, Alaska, for military communication and weapon “defense” purposes. They also take part in biological warfare “testing” over land, water, and city, whereby defense contractor jets, such as those crafted especially for war or weather programs by BAE Systems (owner of the HAARP facility) or Raytheon (owner of the HAARP patent), for the Navy and Air Force and NATO, disperse hazardous toxins into the air and then attempt to eradicate them with chemicals or jet-mounted microwave radiation weapons (like AESA). In addition, the Lockheed Martin and Boeing corporations joined up in a B2B contract with BAE and Raytheon, hardware and software hosted by none other than Microsoft, so that their defense contractor industry market could remain consistently and wirelessly networked, and would never be halted by distance, time, or situational awareness. The NOAA, a member of the Weather Modification Operations and Research Board, (partnered on that board with the American Meteorological Society and the National Science Foundation) sold its weather reporting functionality to Raytheon, who operates it now under the name Advanced Weather Information Processing System. Raytheon happens to contract many of its services and industrial airliners to the tune of global weather modification programs, such as those ever popular “global warming mitigation” or “global dimming” programs, (whereby jets utilizing liquid propane, liquid nitrogen, silver iodide, potassium chlorate, barium oxide, acrylamides, and trimethyl aluminum, spray these chemicals to replace cloud cover over entire countries) and, they’ve even managed to create, through their sub-company General Dynamics Robotics, Unmanned Autonomous Vehicles such as the Global Hawk that can fly for 72 hours, with a payload of 20,000 lbs or more, running entirely on programming and artificial intelligence microwave signal networking, without landing or refueling. It’s not just local chemical “cloud seeding” or “storm prevention” anymore, as is still practiced by the state-and-regional program member companies of the Weather Modification Association.

# World's most powerful laser to tear apart the vacuum of space

Due to follow in the footsteps of the Large Hadron Collider, the latest "big science" experiment being proposed by physicists will see the world's most powerful laser being constructed.
Capable of producing a beam of light so intense that it would be equivalent to the power received by the Earth from the sun focused onto a speck smaller than a tip of a pin, scientists claim it could allow them boil the very fabric of space – the vacuum.

Contrary to popular belief, a vacuum is not devoid of material but in fact fizzles with tiny mysterious particles that pop in and out of existence, but at speeds so fast that no one has been able to prove they exist.
The Extreme Light Infrastructure Ultra-High Field Facility would produce a laser so intense that scientists say it would allow them to reveal these particles for the first time by pulling this vacuum "fabric" apart.
They also believe it could even allow them to prove whether extra-dimensions exist.

# How we recreated the early universe in the laboratory

##### May 12, 2015

- Instead of focusing our attention on immense particle accelerators, we turned to the ultra-intense lasers available at the Central Laser Facility at the Rutherford Appleton Laboratory in Oxfordshire, UK. We used an ultra-high vacuum chamber with an air pressure corresponding to a hundredth of a millionth of our atmosphere to shoot an ultra-short and intense laser pulse (hundred billions of billions more intense that sunlight on the Earth surface) onto a nitrogen gas. This stripped off the gas' electrons and accelerated them to a speed extremely close to that of light.

The beam then collided with a block of lead, which slowed them down again. As they slowed down they emitted particles of light, photons, which created pairs of electrons and their anti-particle, the positron, when they collided with nuclei of the lead sample. A chain-reaction of this process gave rise to the plasma.

However, this experimental achievement was not without effort. The laser beam had to be guided and controlled with micrometer precision, and the detectors had to be finely calibrated and shielded – resulting in frequent long nights in the laboratory.

But it was well worth it as the development means an exciting branch of physics is opening up. Apart from investigating the important matter-antimatter asymmetry, by looking at how these plasmas interact with ultra powerful laser beams, we can also study how this plasma propagates in vacuum and in a low-density medium. This would be effectively recreating conditions similar to the generation of gamma-ray bursts, some of the most luminous events ever recorded in our universe.

No Big Bang? Quantum equation predicts universe has no beginning

# Holometer rules out first theory of space-time correlations

##### December 4, 2015
http://phys.org/news/2015-12-holometer-theory-space-time.html

The Holometer is a deceptively simple device. It uses a pair of laser interferometers placed close to one another, each sending a one-kilowatt beam of light through a beam splitter and down two perpendicular arms, 40 meters each. The light is then reflected back into the beam splitter where the two beams recombine. If no motion has occurred, then the recombined beam will be the same as the original beam. But if fluctuations in brightness are observed, researchers will then analyze these fluctuations to see if the splitter is moving in a certain way, being carried along on a jitter of space itself.

According to Fermilab's Aaron Chou, project manager of the Holometer experiment, the collaboration looked to the work done to design other, similar instruments, such as the one used in the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment. Chou said that once the Holometer team realized that this technology could be used to study the quantum fluctuation they were after, the work of other collaborations using laser interferometers (including LIGO) was invaluable.

"No one has ever applied this technology in this way before," Chou said. "A small team, mostly students, built an instrument nearly as sensitive as LIGO's to look for something completely different."

The challenge for researchers using the Holometer is to eliminate all other sources of movement until they are left with a fluctuation they cannot explain. According to Fermilab's Chris Stoughton, scientist on the Holometer experiment, the process of taking data was one of constantly adjusting the machine to remove more noise.

"You would run the machine for a while, take data, and then try to get rid of all the fluctuation you could see before running it again," he said. "The origin of the phenomenon we're looking for is a billion billion times smaller than a proton, and the Holometer is extremely sensitive, so it picks up a lot of outside sources, such as wind and traffic."

If the Holometer were to see holographic noise that researchers could not eliminate, it might be detecting noise that is intrinsic to space-time, which may mean that information in our universe could actually be encoded in tiny packets in two dimensions.

The fact that the Holometer ruled out his theory to a high level of significance proves that it can probe time and space at previously unimagined scales, Hogan said. It also proves that if this quantum jitter exists, it is either much smaller than the Holometer can detect, or is moving in directions the current instrument is not configured to observe.

So what's next? Hogan said the Holometer team will continue to take and analyze data, and will publish more general and more sensitive studies of holographic noise. The collaboration already released a result related to the study of gravitational waves.

And Hogan is already putting forth a new model of holographic structure that would require similar instruments of the same sensitivity, but different configurations sensitive to the rotation of space. The Holometer, he said, will serve as a template for an entirely new field of experimental science.

"It's new technology, and the Holometer is just the first example of a new way of studying exotic correlations," Hogan said. "It is just the first glimpse through a newly invented microscope."

# Nanoparticles found to violate second law of thermodynamics

April 3, 2014

It may be a little late for April Fool's, but some skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the flow of entropy and heat in, it was believed, any situation. Specifically, researchers from three universities theoretically proposed then demonstrated that a nanoparticle in a state of thermal non-equilibrium does not always behave as larger particles might under the same conditions, with implications for various fields of research.
The second law of thermodynamics is the one that makes perpetual motion machines impossible. It states that the entropy – the measure for the disorder of a system – of any isolated system cannot decrease spontaneously, with the system evolving towards the state of maximum entropy (favoring disorder). The team has shown that a nanoparticle trapped with laser light temporarily violates this law. This seeming violation of universal law is transient, something that the researchers first derived as a mathematical model of fluctuations expected at the nanoscale.

# Scientists announce breakthrough in quest for fusion power

February 13, 2014

http://www.gizmag.com/fusion-breakthrough/30814/?li_source=LI&li_medium=default-widget

In a perfect example of beating swords into plowshares, a team of scientists at the Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) in California reached a milestone in the quest for practical fusion power using a process designed for the development and testing of nuclear weapons. The announcement in the February 12 issue of Nature claims that the team used the world’s most powerful laser barrage to produce a controlled fusion reaction where more energy was extracted from the fuel than was put into it.

If there is an ultimate engineering dream, then nuclear fusion is about as close as close as one can get. By literally harnessing the power of the stars, it holds the promise of what is, for all practical purposes, unlimited clean energy. Since man-made fusion was first demonstrated in 1951 with a boosted fission weapon, scientists and engineers have worked on some way to produce a practical fusion reactor instead of a hydrogen bomb.

The story of the fusion reactor is one of both great progress, but also constant frustration. When work began, the first reactor was predicted to be 25 years away. Since then and up until today, it’s still 25 years away. That’s because although nuclear fusion is relatively simple in theory, getting a controlled reaction started outside of the heart of a star is extremely difficult. The trick is to reach the “ignition” point, where the energy released by the reactor is greater than what’s put into it and the reaction becomes self-sustaining.

A fusion reactor works by simulating the conditions inside the Sun. Put simply, hydrogen atoms fuse in the Sun because its huge mass squashes the atoms together to form helium, releasing huge amounts of energy as the strong nuclear force that keeps them apart is overcome. A hydrogen bomb does the same thing, only with a fission bomb creating the necessary conditions for a millionth of a second.
---------------------

# Scientists have come one step closer to harnessing the power of the sun. Researchers at the National Ignition Facility (NIF) have passed a milestone in achieving self-sustaining nuclear fusion -- but you won't hear about it from the researchers. The NIF team has been furloughed as a result of the U.S. government shutdown, which began on Oct. 1, and is not releasing updates to the press.

According to the BBC, a research experiment conducted in late September succeeded in releasing more energy through a fusion reaction than it absorbed by the fuel going in. NIF is the first research facility in the world to achieve this goal. A spokesperson for the NIF could not give CBSNews.com a comment on the results of the experiment.

NIF's method for achieving fusion involves sending 192 laser beams through a 1,500-meter journey that increases its energy output by a factor of more than a quadrillion. The laser beams' energy grows from one-billionth of a joule to 4 million joules in 5 millionths of a second.

A breakthrough in nuclear fusion is widely considered the holy grail of achieving an unlimited clean energy source.
Scientists believe that fusion can fuel our future without threat of nuclear proliferation or environmental damage because the process of creating fusion requires very few resources. One of the biggest challenges in producing energy derived from fusion has been to pass the break-even point -- a goal that has eluded scientists for nearly 50 years.
Nuclear fusion is not to be confused with nuclear fission. Instead of splitting an atom's nucleus, like in fission, nuclear fusion is the process of bringing together two atomic nuclei to form a new nucleus.
While the NIF has passed the break-even point, it is just shy of reaching "ignition" -- when nuclear fusion produces as much energy as is supplied to the lasers.

Weather could be controlled using lasers

## Experts from around the world are to gather at the World Meteorological Organisation next month to discuss how powerful laser pulses can be used to generate changes in the atmosphere that influence the weather.

Their experiments have shown that intense pulses of light can cause ice to form and water to condense, leading to the formation of clouds.
The scientists have now begun testing their equipment outside for the first time with extremely short pulses of laser light were fired into the sky.
Researchers have also proved that lightning discharges can be triggered and channelled through the air using laser pulses.
There is a long history of attempts by scientists to control the weather, including using techniques such as cloud seeding.

This involves spraying small particles and chemicals into the air to induce water vapour to condense into clouds.

In the 1960s the United States experimented with using silver iodide in an attempt to weaken hurricanes before they made landfall.

The USSR was also claimed to have flown cloud seeding missions in an attempt to create rain clouds to protect Moscow from radioactive fallout from the Chernobyl nuclear disaster.

More recently the Russian Air force has also been reported to have used bags of cement to seed clouds.

Before the 2008 Olympic Games in Beijing, the Chinese authorities used aircraft and rockets to release chemicals into the atmosphere.
Other countries have been reported to be experimenting with cloud seeding to prevent flooding or smog.

However, Professor Wolf, Dr Kasparian and their colleagues believe that lasers could provide an easier and more controllable method of changing the weather.
They began studying lasers for their use as a way of monitoring changes in the air and detecting aerosols high in the atmosphere.

# Laser-induced condensation shows promise for cloud seeding

Over the past decade, commercially-available lasers have increased in power by two orders of magnitude, reaching the petawatt level, with exawatts firmly within sight. The 2011 experiment used a 100 terawatt laser, and a "mobile" (actually the size of a shipping container) laser of five terawatts.
Further understanding of how lasers spur condensation will also help. The process, known as photodissociation, involves the laser's photons breaking down atmospheric compounds to produce ozone and nitrogen molecules. Those in turn form nitric acid particles, which bind water molecules together into droplets.

Second Conference on Laser, Weather and Climate (LWC 2013) -

http://www.laserweatherandclimate.com/

Welcome

As highlighted by the success of the first Conference on Laser-based Weather Control in 2011, ultra-short lasers launched into the atmosphere have emerged as a promising prospective tool for weather modulation and climate studies. Such prospects include lightning control and laser-assisted condensation, as well as the striking similarities between the non-linear optical propagation and natural phenomena like rogue waves or climate bifurcations.

Filaments generated by ultra-short laser pulses launched into the atmosphere have emerged as an unexpected prospective tool for weather modulation. In particular, lightning control and laser-assisted water condensation recently appeared as spectacular prospects in this direction.

Although these new perspectives triggered an increasing interest and activity in many groups worldwide, the highly interdisciplinary nature of the subject limited its development, due to the need for enhanced contacts between laser and atmospheric physicists, chemists, electrical engineers, and meteorologists.

# Weather modification

http://en.wikipedia.org/wiki/Weather_modification

Proposed US Legislation

2005 U.S. Senate Bill 517 and U.S. House Bill 2995 U.S. Senate Bill 517 and U.S. House Bill 2995 were two bills proposed in 2005 that would have expanded experimental weather modification, to establish a Weather Modification Operations and Research Board, and implemented a national weather modification policy. Neither were made into law. Former Texas State Senator John N. Leedom was the key lobbyist on behalf of the weather modification bills.

2007 U.S. Senate Bill 1807 & U.S. House Bill 3445 Senate Bill 1807 and House Bill 3445, identical bills introduced July 17, 2007, proposed to establish a Weather Mitigation Advisory and Research Board to fund weather modification research.

# Extending life of plasma channels could allow lasers to be used as lightning rods

#### http://www.gizmag.com/plasma-channels-laser-lightning-rods/39588/

Today's simple metal lightning rods may be on their way to obsolescence. That's because scientists at The Hebrew University of Jerusalem are developing a high-tech alternative that could potentially reach higher and be more effective – laser lightning rods.

When a high-power laser is shot into the sky, it ionizes airborne molecules in the process. As a result, even once the laser itself is shut off, a trail of ionized particles known as a plasma channel is left in its place. Plasma channels conduct electricity, not unlike a good ol' steel rod.

Led by scientist Jenya Papeer, the Jerusalem team successfully created plasma channels measuring 100 microns in diameter, by firing a laser in pulses lasting just 100 femtoseconds each. Unfortunately, however, after three nanoseconds the plasma cooled off and the channels ceased to exist.

In order to boost those trails' longevity by a factor of 10, the researchers added a second laser that is fired in 10-nanosecond bursts along the path of the first one. Its wider beam envelopes the plasma created by the first beam, keeping it hot and conductive. By boosting the power of that second laser, or even by adding additional beams, it is hoped that the lifespan and the length of the plasma channels could be lengthened further.

Speaking of which, though, the first plasma channels to be produced were only a meter (3.3 ft) long. The researchers addressed this limitation by creating an array of lenses that change the way in which the laser is focused. As a result, it now creates a series of three one-meter-long channels linked end-to-end, effectively forming one 3-meter plasma channel.

That said, by further adjusting the focus and using a powerful enough laser, it should be possible to produce any number of linked plasma channels, creating a lightning rod of any desired length.

A paper on the research will be presented on Oct. 22nd at the Frontiers in Optics conference, in San Jose, California.

# Atmospheric Vortex Engine creates tornadoes to generate electricity

December 20, 2012

Tornadoes generally evoke the destructive force of nature at its most awesome. However, what if all that power could be harnessed to produce cheaper and more efficient electricity? This is just what Canadian engineer Louis Michaud proposes to achieve, with an invention dubbed the “Atmospheric Vortex Engine” (or AVE).

AVE works by introducing warm air into a circular station, whereupon the difference in temperature between this heated air and the atmosphere above creates a vortex – or controlled tornado, which in turn drives multiple wind turbines in order to create electricity. The vortex could be shut down by simply turning off the source of warm air.

Tiny magnets mimic steam, water and ice

September 21, 2015

Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state. This material made of nanomagnets might well be refined for electronic applications of the future – such as for more efficient information transfer.

# Volcanic ash proves inefficient cloud ice maker

May 28th, 2015

When tons of ash spewed into the atmosphere from a 2010 Icelandic volcano it caused havoc for vacationers across Europe. But did it also dramatically change clouds? Researchers at Pacific Northwest National Laboratory found that volcanic ash is not as efficient as common dust in birthing clouds' ice particles. Using a novel laboratory testing chamber they formed cloud ice, a process called ice nucleation, around particles of dust and volcanic ash. Their results revealed the importance of optimal particle structure to efficiently attract super cold water vapor to nucleate ice.

Enhancement of electron energy during vacuum laser acceleration in an inhomogeneous magnetic field

In this paper, the effect of a stationary inhomogeneous magnetic field on the electron acceleration by a high intensity Gaussian laser pulse is investigated. A focused TEM (0,0) laser mode with linear polarization in the transverse x-direction that propagates along the z-axis is considered. The magnetic field is assumed to be stationary in time, but varies longitudinally in space. A linear spatial profile for the magnetic field is adopted. In other words, the axial magnetic field increases linearly in the z-direction up to an optimum point zm and then becomes constant with magnitude equal to that at zm . Three-dimensional single-particle simulations are performed to find the energy and trajectory of the electron. The electron rotates around and stays near the z-axis. It is shown that with a proper choice of the magnetic field parameters, the electron will be trapped at the focus of the laser pulse. Because of the cyclotron resonance, the electron receives enough energy from the laser fields to be accelerated to relativistic energies. Using numerical simulations, the criteria for optimum regime of the acceleration mechanism is found. With the optimized parameters, an electron initially at rest located at the origin achieves final energy of γ=802 . The dynamics of a distribution of off-axis electrons are also investigated in which shows that high energy electrons with small energy and spatial spread can be obtained.

Lazers sound like a good medical technology. We must question and see to it, that this technology is abused, by the wrong type of people. Imagine if the government could secretly administer the entire population with a vaccine, without their knowledge, just by pointing a lazer at them. You could even have multiple lazers targeting multiple individuals, for whatever type of chemicals you want to inject in them. Whether that chemical is medicinal or a poison. We must make the public aware of this type of technology, and how we should take steps in our civilization, to make sure that the governments and other individuals, do not abuse this type of technology, especially on a mass scale.  Technically, all it would take is someone to point a lazer at someone, and that person could die from the administered chemicals in the lazer instantly or over a period of time.

# Jellyfish proteins used to create polariton laser

##### August 22, 2016

A combined team of researchers from Scotland and Germany has developed a way to create a polariton laser by using jellyfish proteins cultivated in E. coli cells. In their paper published in the journal Science Advances, the team describes their technique and possible uses for the result.

As most people know, at a basic level, conventional lasers work by bouncing light around inside of a cavity and then emitting identical photons as a beam. There is another type of laser that is less well known, the polariton laser—it works by tossing photons back and forth between excited molecules. But the reason it has not made its way into commercial use is because it must be cooled to an extremely low temperature to work properly. In this new approach, the researchers report the development of such a laser that works at room temperatures.
