Diamond Batteries Made of Nuclear Waste Can Generate Power For Thousands of Years. Nuclear Diamonds Scientists from the University of Bristol Cabot Institute are hitting two birds with one stone, thanks to their lab-made diamond that can generate electricity and is made from upcycled radioactive waste.
In nuclear power plants, radioactive uranium is split in a process called nuclear fission. When the atoms are split, heat is generated, and that heat then vaporizes water into steam that turns electricity-generating turbines. A severe downside of this process is the creation of dangerous radioactive waste, which ultimately deposits in the graphite core that it is housed in. Today, this nuclear contamination is safely stored away until it stops being radioactive…and with a half-life of 5,730 years, that takes quite a while. The scientists found a way to heat the radioactive graphite to release most of the radioactivity in a gaseous form. When these diamonds are placed near a radioactive field, they generate a small electrical current.
Powering the Future. Highly Efficient And Ultra-Cheap Perovskite Solar Cells Announced. How cheap can solar power get?
We don't know yet, but the astonishing fall in the price of solar panels is clearly only going to continue with the announcement that perovskite solar cells have broken the 20 percent efficiency mark. The announcement comes just two days after leading researchers described perovskite as the future of solar power and probably electricity generation in general. There are many ways to produce electricity from sunlight, but the market for solar power is dominated by silicon crystal cells. Most alternatives are substantially less efficient or ridiculously expensive. In the last few years, however, there has been intense speculation about cells made from perovskite, a class of crystals with a structure mimicking naturally occurring calcium titanium oxide. Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol. Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change.
Their findings were published in the journal ChemistrySelect. [Go here for a new in-depth interview about the findings with one of the lead researchers.] The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself.
The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles. Physics Breakthrough: Quantum Cat State Finally Captured on Camera. In Brief A breakthrough experiment captured in a movie one of quantum physics' most bizarre demonstrations of the nature of subatomic particles: Schrödinger's cat.
This may help us understand molecular behavior better, and how they affect living systems. Physicists just discovered a totally new form of light. Physicists have just discovered a new form of light that doesn't follow our existing rules of angular momentum, and it could shake up our understanding of the electromagnetic radiation and lead to faster, more secure optical communication.
Because of how well-studied and, well, everywhere, light is, you might assume that we've pretty much learnt all there is to know about it. Revolutionary! Turbines inspired by BOATS from ancient Carthage could spell the end of offshore wind farms. Tunisian inventors have looked to the past for inspiration in their designs for a more efficient way of capturing wind energy.
A start-up has developed a new design of bladeless turbine, inspired by the sails on ships from Ancient Carthage.

Researchers accidentally discover a way to make batteries last basically forever. Inventors joke about building “a better mousetrap,” but these days, it’s a better battery that everyone actually wants.
Researchers at the University of California, Irvine have made a breakthrough that could lead to just that. Using gold and some new-fangled materials, the team built a nanowire battery that maintains its performance after hundreds of thousands of charging cycles. Compared to existing lithium-ion battery technology, this could shift the future of energy storage forever – and the whole thing was discovered on accident. Rechargeable lithium ion batteries slip in performance over time, after being charged and recharged hundreds of times. Unexpected discovery leads to a better battery. Renewable energy storage possible thanks to chemical conversions April 18, 2016 Frances White, PNNL, (509) 375-6904.
Scientists in Germany Take a Major Step Towards Nuclear Fusion. Researchers develop first high-gravity, one-pot process for producing cellulosic ethanol. The falling price of gasoline at the pumps may warm the hearts of consumers but it chills the souls of scientists who recognize that humankind must curtail the burning of fossil fuels to reduce the threat of climate change.
Biofuels can help mitigate climate change and provide us with a sustainable source of transportation energy if yields and production costs are economically competitive. A major step towards achieving this goal has been achieved by researchers with the U.S. New 'nano-reactor' biomaterial catalyzes hydrogen biofuel. BLOOMINGTON, Ind., Jan. 5 (UPI) -- By hiding a modified enzyme inside a virus, researchers have created a new biomaterial capable of efficiently catalyzing the production of hydrogen.
The so-called "nano-reactor" could lead to more efficient and profitable biofuel production processes. Inside a capsid, the protective protein shell of a virus, the hydrogen-producing enzyme is 150 times more efficient than an unaltered enzyme. "Essentially, we've taken a virus's ability to self-assemble myriad genetic building blocks and incorporated a very fragile and sensitive enzyme with the remarkable property of taking in protons and spitting out hydrogen gas," researcher Trevor Douglas, a chemist at Indiana University, explained in a press release. Researchers just made batteries from mushrooms... and they're surprisingly good.
Researchers in the US have created a new type of lithium-ion battery that uses portabella mushrooms - yes, you read that right - instead of the graphite that currently forms the batteries inside our mobile phones. And while it sounds like the type of idea you might hear at a high school science fair, evidence suggests that these new batteries might actually last longer than traditional batteries, and could give our phones better battery life as they age. And that's not all - the mushroom batteries are also incredibly cheap, easy to make, and, best of all, they're pretty much biodegradable.
Which will make a big difference to the environment as our demand for batteries skyrockets with the 6 million electric vehicles predicted to be built by 2020. Scientists make huge hydrogen energy discovery. It’s one of the holy grails of the energy industry: a cost-effective way to generate hydrogen, and a team of researchers thinks they may have just found it. Scientists at the University of Wisconsin believe the have found a cheap and efficient way to produce hydrogen without having to use noble gases as a catalyst, and they were able to do it by combining phosphorous and sulfur, two common elements, as well as cobalt, a metal that is much cheaper than even the cheapest noble metal, according to a UPI report.
Biologically speaking, sugar molecules are energy-dense, easy to transport, and cheap to digest. There is a reason why almost every living cell on Earth generates its energy (ATP) from glucose. Now, researchers at Virginia Tech have successfully created a sugar-powered fuel cell that has an energy storage density of 596 amp-hours per kilo — or “one order of magnitude” higher than lithium-ion batteries. Now, it’s not exactly news that sugar is an excellent energy source. A fully transparent solar cell that could make every window and screen a power source. New "Solar Fuel Cell" Is More Efficient By A Factor Of 10. Clean Power Published on July 22nd, 2015 | by Tina Casey July 22nd, 2015 by Tina Casey Providing a new ray of hope for hydrogen fuel cell fans, researchers at Eindhoven University of Technology have developed a more efficient way to produce the fuel needed to keep fuel cells going — namely, hydrogen.
We’ve been giving hydrogen the stinkeye because it is sourced primarily from fossil natural gas, but the Eindhoven solution works on solar energy and water, and gallium phosphide aka GaP. The artificial leaf that could power the world. As Daniel Nocera gazed down on one of his experiments in what has come to be known as the "holy grail" of energy research, his response was to shrug: "Oh, that can't be right. " It was a glass of tap water with a thumb-sized strip of silicon floating in it. When he held the glass up to the light, the strip began to gently bubble. It seemed to be splitting water into hydrogen and oxygen. Plant-e Modular. The modular system is the first product that Plant-e introduced to the market (launched in 2014). Artificial Photosynthesis Yields Valuable Chemicals.
Tiny semiconductors and bacteria have been combined to create a system that uses sunlight to turn carbon dioxide into valuable chemicals. Photosynthesis forms the basis of most life on Earth. Audi have successfully made diesel fuel from carbon dioxide and water. German car manufacturer Audi has reportedly invented a carbon-neutral diesel fuel, made solely from water, carbon dioxide and renewable energy sources. And the crystal clear 'e-diesel' is already being used to power the Audi A8 owned by the country’s Federal Minister of Education and Research, Johanna Wanka. The creation of the fuel is a huge step forward for sustainable transport, but the fact that it’s being backed by an automotive giant is even more exciting. Audi has now set up a pilot plant in Dresden, Germany, operated by clean tech company Sunfire, which will pump out 160 litres of the synthetic diesel every day in the coming months. Japan space scientists make wireless energy breakthrough.

Teens Create A Way To Use Urine As Fuel. Fusion energy milestone reported by California scientists. “You kind of picture yourself climbing halfway up a mountain, but the top of the mountain is hidden in clouds,” Omar Hurricane, the lead author of the Nature paper, said in a teleconference with journalists. “And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’
You just don’t know.” Hurricane and other scientists at the Lawrence Livermore National Laboratory, home of the multibillion-dollar National Ignition Facility, took pains to calibrate their claims of success. This was not fusion “ignition,” the NIF’s ultimate ambition. The experiment overall requires much more energy on the front end — all those laser shots —than comes out the back end. Only about 1 percent of the energy from the laser actually winds up in the fuel, according to Debra Callahan, a co-author of the Nature paper. Giant glass orb could replace the solar panel. Glucose-based battery has 10 times energy of lithium: researchers. MIT researchers find messy batteries might be better. As modern technology demands more and more power, lithium-ion batteries have been getting increasingly dense. There hasn’t been a true breakthrough in battery technology recently, so scientists have been working on ways to fit more components inside the same space. That means very precise work to keep everything neat and tidy.
