#Whoa, researchers have levitated liquid droplets on glowing plasma French researchers have found a new way to levitate liquid droplets by using a stream of electricity to create a tiny cushion of plasma.
But researchers from The french Alternative energies and Atomic energy commission have devised now a new method managing to float liquid droplets using plasma.
But after further research, they found that by using electricity to make the vapour cushion instead of heat,
which gave rise to the very high electric field necessary to generate a long-term and dense plasma with little energy.
The tests come after a feasibility study looking into how dynamic battery charging could solve the problem of electric vehicles running out of juice,
and now a record-breaking solar device made by Australian scientists could mean a whole new category of clean energy production is just around the corner.
Success in the field of artificial photosynthesis normally means achieving an energy efficiency of above 10 percent.

#This transparent lithium-ion battery charges itself with sunlight Researchers in Japan have invented a rechargeable lithium-ion battery that can charge itself using sunlight-no solar cell required.
and the team behind it hopes to see the technology integrated into a mart windowthat can act as both a large rechargeable battery and a photovoltaic cell all at once.
Theye since been working towards a battery-integrated window that can store energy from sunlight while also changing its structure automatically to provide a tint during the day.
when the battery is exposed to sunlight, it becomes tinted to about 30 percent light transmittance,
and this allows the energy to be captured more efficiently.""The trick in getting them to be nearly transparent is in making them really thin-the electrodes are just 80 nm
Back in 2013, the main component of the electrolyte for the battery's positive electrode was lithium iron phosphate,
and for the electrolyte used for the negative electrode, they used lithium titanate and lithium hexafluorophosphate-both
of which are used commonly in rechargeable lithium-ion batteries. For the prototype that was put on display in Tokyo last month,
the team reports an output from the battery of 3. 6 volts, and say they managed to successfully complete 20 charge/discharge cycles.
another possibility for the technology is self-charging smartphone screens made from transparent lithium-ion batteries.
when a US ARMY vet used the battery-powered prosthetic to scale a rock-climbing wall, using nothing but his brain power.
Now the team behind the technology has demonstrated how the battery-powered device can impart the feeling of touch on top of grip, movement,
and the vaporisation part of the process doesn't require any electricity. This means the new method is both inexpensive and suitable for areas without a regular power supply-both factors that are very important for developing countries.
and consumes a whole lot of extra energy, which actually makes it less efficient than if we just used electrons in the first place.

#London is now recycling energy from train brakes to power their stations London has just finished testing a new system that can collect
and recycle energy generated by their Tube trains when they brake, and it already powering their stations completely for more than two days per week.
The city reports that it already shaving 5 percent off the annual energy bill which might not sound like much,
"The trial puts London at the cutting edge of this kind of technology and clearly demonstrates how energy from trains can be recovered to power Tube stations,
Deputy Mayor for Environment and Energy, said in a press statement.""This complements our wider work to make other forms of public transport cleaner
The system works by collecting energy generated by the trains when they brake before feeding it back into the power mains as electricity."
"In hybrid and electric cars, such recovery systems can help improve range, but in large heavily-packed passenger trains running regularly in one of the most heavily traveled cities in the world,
According to the London transport authority, it collected an average of 1 Megawatt hour (MWH) of energy each day,
Another benefit of the inverter system is that by collecting up the energy and turning it into electricity
"This state-of-the-art regenerative braking system has the potential to transform how we power stations across the...
and significantly reducing our energy bills,"Chris Tong, LU's Head of Power and Cooling, said in a press release."
"We are committed to doing more to reduce our energy use, and this technology-a world-first for metro railways-is one of a number of innovations we're embracing to lower our environmental impact."

In addition to Tu's malaria drug, Artemisinin, China has pioneered also development of solar and wind technology, and is working on trains that will reach 500 km h.
direct air capture works just like these new solar cells that split water into a hydrogen fuel-the CO2 recycling plant extracts CO2 from the air using a giant complex of fans,
A major limitation of solar and wind technologies, on the other hand, is that they require specific technologies to capture

#Researchers create lithium-air battery that could be 10x more powerful than lithium-ion A new lithium-air battery created by researchers at the University of Cambridge points the way to the ultimate battery packs of the future,
the new test battery could prove an important stepping stone in the development of this essential technology.
If you're getting tired of announcements about breakthroughs in battery technology, that's understandable: as they're so essential to modern life,
Any new battery has to improve on what we already have, be safe to use in consumer gadgets,
and that's why many'miracle'batteries have fallen since by the wayside once the initial lab work is done,
not just for smartphones but for electric cars and solar power, where batteries are essential for storing energy to use
The idea of a lithium-air or lithium-oxygen battery isn't new scientists have known for a while that these types of batteries can hold up to 10 times the charge of today's lithium-ion packs (imagine not having to charge your phone for a whole week.
The new battery from the Cambridge university lab has a higher capacity, better efficiency and improved stability compared with previous attempts this stability,
crucial if we're to put these batteries into millions of cars and smartphones, was reached by using a'fluffy'carbon electrode made from graphene.
What's more, by changing the chemical mix from earlier versions of lithium-air batteries,
the researchers were able to prevent the battery from degrading significantly over time.""What we've achieved is a significant advance for this technology
The demonstration battery produced by the scientists still needs pure oxygen in order to charge not something many of us have a ready supply of
and there's still the risk of the battery exploding due to the dendrites (spindly lithium metal fibres) created during the charging process.
using little energy at a low cost, it is now possible with Mexican technology, thanks to the creation of a solar cooling system designed by Susana Elvia Toledo Flores.

#Researchers discover N-type polymer for fast organic battery The discovery relies upon a"conjugated redox polymer"design with a naphthalene-bithiophene polymer,
which has traditionally been used for applications including transistors and solar cells. With the use of lithium ions as dopant, researchers found it offered significant electronic conductivity
and discharging energy. The breakthrough, described in the Journal of the American Chemical Society and featured as ACS Editors'Choice for open access, addresses a decades-long challenge for electron-transport conducting polymers,
and discharging energy, Yao said. The discovery could lead to a cheaper alternative to traditional inorganic-based energy devices,
including lithium batteries. Ultimately Yao said, it could translate into less expensive consumer devices and even less expensive electric cars.
Yao's research group focuses on green and sustainable organic materials for energy generation and storage.
He is also a principal investigator for the Texas Center for Superconductivity at UH. Yanliang Liang, a research associate at UH and first author on the paper, said researchers aren't trying to compete directly with conventional lithium-ion batteries."
"We are trying to demonstrate a new direction, "he said. Liang said conventional inorganic metal-based batteries
and energy storage devices are expensive partly because the materials used to make them, including cobalt and silicon-based compounds,
require huge energy expenditures to process. Organic polymers can be processed at relatively low temperatures, lowering the cost.
They also produce less CO2, he said, adding to their environmental advantage. And while conventional materials are finite,
organic polymers could potentially be synthesized from biomass.""Organic-conjugated polymers are emerging as a materials class for energy-related applications,
enabling a path to a more sustainable energy landscape without the need of energy-intensive, expensive and sometimes toxic metal-based compounds,
"the researchers wrote, concluding that"a model polymer, P (NDI2OD-T2), was stably and reversibly n-doped to a high doping level of 2. 0,
and see widespread applications, especially in energy-related ones such as batteries, supercapacitors and thermoelectrics.""The basic polymer used in the work was discovered in 2009;
allowing a battery to be charged 80 percent within 6 seconds and fully charged in another 18 seconds,
Conventional inorganic batteries still are capable of holding more energy than the organic battery, and Yao said work will continue to improve the storage capacity of the material.
"This means we have demonstrated the most important step toward a hydrogen economy--producing distributed and affordable green hydrogen from local biomass resources,
and how it plays into the future of alternative energy production.""Joe Rollin, a former doctoral student of Zhang's at Virginia Tech and cofounder with Zhang of the start-up company Cell-free Bioinnovations, is the lead author on the paper.
the Virginia Tech team used dirty biomass--the husks and stalks of corn plants--to create their fuel.
#First metal-free catalyst created for rechargeable zinc-air batteries Zinc-air batteries are expected to be safer, lighter, cheaper and more powerful and durable than lithium-ion batteries common in mobile phones and laptops and increasingly used in hybrid and electric cars.
This carbon-based catalyst works efficiently in both the oxygen reduction reaction and oxygen evolution reaction, making the battery rechargeable.
The catalyst is also inexpensive, easy to make and more ecological than most of the alternative materials.
"With batteries, cost is always an issue and metal-free catalysts can reduce cost while improving performance,"said Liming Dai,
"These batteries could be used in computers, data stations, for lighting--anyplace batteries are used now.""Dai worked with Case Western Reserve postdoctor Jintao Zhang,
who performed experimental work; and North Texas University's Zhenhai Xia, professor of materials science and engineering, and Zhenghang Zhao, a Phd student, who performed theoretical simulations.
Zinc-air batteries mix oxygen from the air with zinc in a liquid alkaline electrolyte to create a charge.
The batteries can have three times the energy density of lithium-ion batteries, but have been sluggish. To counter that problem,

researchers have not developed ultra-stretchable and fully-reversible energy conversion devices properly. Recently researchers from KAIST and Seoul National University (SNU) have collaborated
These noteworthy results were achieved by the non-destructive stress-relaxation ability of the unique electrodes as well as the good piezoelectricity of the device components.
The new SEG can be applied to a wide-variety of wearable energy harvesters to transduce biomechanical-stretching energy from the body (or machines) to electrical energy.
"The device the team has developed--called the D3 (digital diffraction diagnosis) system--features an imaging module with a battery-powered LED light clipped onto a standard smartphone that records high-resolution imaging data with its camera.
When connected to an electrical power source, and wrapped over a multilayer polymer composite, the heated film stimulates the polymer to solidify.
--while using only 1 percent of the energy. The new"out-of-oven"approach may offer a more direct
energy saving method for manufacturing virtually any industrial composite, says Brian L. Wardle, an associate professor of aeronautics and astronautics at MIT."
The team measured the energy required to solidify or cross-link, the polymer and carbon fiber layers, finding that the CNT film used one-hundredth the electricity required for traditional oven-based methods to cure the composite.
Both methods generated composites with similar properties, such as cross-linking density. Wardle says the results pushed the group to test the CNT film further:
#Graphene pushes the speed limit of light-to-electricity conversion ICFO researchers Klaas-Jan Tielrooij, Lukasz Piatkowski,
The new device that the researchers developed is capable of converting light into electricity in less than 50 femtoseconds (a twentieth of a millionth of a millionth of a second.
Thus, the energy absorbed from light is efficiently and rapidly converted into electron heat. Next, the electron heat is converted into a voltage at the interface of two graphene regions with different doping.

#Better battery imaging paves way for renewable energy future"Iron fluoride has the potential to triple the amount of energy a conventional lithium-ion battery can store,
"says Song Jin, a UW-Madison professor of chemistry and Wisconsin Energy Institute affiliate.""However, we have yet to tap its true potential."
There, they collected chemical maps from actual coin cell batteries filled with iron fluoride during battery cycling to determine how well they perform.
"In the past, we weren't able to truly understand what is happening to iron fluoride during battery reactions
because other battery components were getting in the way of getting a precise image, "says Li.
and discharge energy. Thus far, using iron fluoride in rechargeable lithium ion batteries has presented scientists with two challenges.
The first is that it doesn't recharge very well in its current form.""This would be like your smart phone only charging half as much the first time,
"Consumers would rather have a battery that charges consistently through hundreds of charges.""By examining iron fluoride transformation in batteries at the nanoscale,
Jin and Li's new X-ray imaging method pinpoints each individual reaction to understand why capacity decay may be occurring."
The second challenge is that iron fluoride battery materials don't discharge as much energy as they take in, reducing energy efficiency.
"If we can maximize the cycling performance and efficiency of these low-cost and abundant iron fluoride lithium ion battery materials,
