#Making polymer nanostructures from a greenhouse gas (Nanowerk News) A future where power plants feed their carbon dioxide directly into an adjacent production facility instead of spewing it up a chimney
and into the atmosphere is definitely possible, because CO2 isnt just an undesirable greenhouse gas; it is also a good source of carbon for processes like polymer production.
An optical transistor could perform a similar role for light instead of electricity, bringing far faster systems than now possible.
Exposing the material to a pulsing laser light causes electrons to move from one energy level called the valence band to a higher energy level called the conduction band.

Unlike natural materials, metamaterials are able to reduce the index of refraction to less than one or less than zero.
Refraction occurs as electromagnetic waves including light, bend when passing from one material into another. Each material has its own refraction index,

#Nikola Labs unveils new tech to harvest electricity from EMFS; learn history behind Nikola Tesla's free electricity A revolutionary new energy harvesting technology recently unveiled by Nikola Labs,
an Ohio-based startup company inspired by the late inventor and energy genius Nikola Tesla,
promises to capture all those stray radio waves emitted back and forth between wireless phones and the towers through
and convert them back into more energy, extending a smartphone's battery life by as much as 30%.
%Announced as part of an upcoming Kickstarter fundraising campaign, the technology, which Nikola's designers engineered into a special case made for Apple's iphone,
reportedly harvests the electromagnetic radiation transferring to and from mobile phones and converts it into direct current (DC) electrical energy,
which is recycled then back into the phone's battery.""Nikola Technology efficiently converts RF signals like Wi-fi, Bluetooth,
and LTE into DC power using its proprietary energy harvesting circuit, "explains the company on its website."
"The result is usable energy that can provide power to mobile devices wirelessly.""Though not perfect by any means, Nikola energy-capturing case holds promise For a sponsorship contribution of $99,
early supporters of the project will gain exclusive first-issue access to the case, which doesn't so much charge an iphone actively as it does extend its normal battery life.
Still, the case's novelty, and more importantly its longer-term potential, is what stands to inspire a new generation to take advantage of energy inefficiency and waste.
One major drawback to the technology is that its relatively slow to harvest energy, and the case itself doesn't contain an actual battery of its own to store excess charge.
At the same time the case itself is small and form-fits well to the iphone, acting as an all-in-one battery extension package that's sleek, discreet and unobtrusive."
"As magical as this sounds, the iphone case won't be able to charge your phone from zero to 100,

either--the antenna and power-converting circuit can only extend the battery life of an iphone 6 by about 30,
"Tesla's visions of wireless energy threatened the military-industrial complex; were sabotaged his ideas? The official Kickstarter campaign for the case is expected to be launched in June,
and its unveiling is sure to inspire many curious folks to take a closer look at the energy discoveries of the man behind the Nikola name, Nikola Tesla.
Tesla's pie-in-the-sky ideas admittedly led to some pretty amazing breakthroughs in energy technology.
Of particular interest was Tesla's dream of developing a way to transmit energy wirelessly using only air as a medium.

which modified electrical devices were put in their homes along with a Wi-fi router. Over 24 hours, the devices were powered solely by the router's signal,
The energy of the radio waves the router sent out was converted into direct current voltage with a component called a rectifier,
much as solar panels convert light energy into electrical energy. That voltage was boosted then to a useful level by a DC-DC converter (arxiv. org/abs/1505.06815.
The system powered temperature sensors and battery-less low-resolution cameras, and charged standard batteries. The hard part is getting the router to constantly push out enough energy,

#Solar cells that work on cloudy days just hit a record-breaking 22.1%efficiency There's been plenty of good news about solar power lately-not only are governments around the world using it more and more,
traditional solar cells simply don't work that well unless they're in direct, bright sunlight. To rectify this, researchers have been working on creating structures called black silicon solar cells,
which absorb way more light and are useful even on overcast days. But they've never been efficient enough to be real players in the solar race-up until now, that is.
A team of European researchers has announced just that they've set a new record by creating black silicon solar cells that can convert 22.1 percent of the Sun's light into electricity-an increase of almost four percent on their previous record.
While this doesn't compare to the record of 40 percent efficiency in traditional silicon solar cells,
it shows that black silicon solar cells are now real contenders that could help greatly reduce the cost of solar power in the future.
Even more impressively, the team compared their new black silicon solar cells with traditional solar cells of the same efficiency,
and showed that their cells increased daily energy production by 3 percent, thanks to their ability to suck up light even
black cells generate considerably more electricity than traditional cells even though both cells have identical efficiency values."
"What's different about black silicon solar cells is that their surfaces are covered in tiny, nanoscale ridges,
rather than flowing through the cell as electricity-a problem that's created a limit to how efficient the cells could become.
Publishing in Nature Nanotechnology, the researchers report that their resulting cells are the most efficient black silicon solar cells to date, capable of turning 22.1 percent of available light into electricity."
and black silicon solar cells have real potential for industrial production, "the authors write. What's even more exciting about this research is the fact that the team hasn't optimised the new cells as yet,
Basically, this means that we may soon see solar panels on the market that can create electricity no matter where the Sun is in the sky,
