Environmental groups like the Solar Electric Light Fund, which brings green energy to impoverished areas of the globe, have been featured on Philanthroper.
Take the case of Deng Xunming, a China-born U.S. citizen who is a pioneer of America's solar industry and whose innovations light up the first solar-powered billboard on New York's Times Square.
Their solar-powered light had become a serious endeavor that needed to go beyond the classroom.

In addition to these goodies, the solar wind carries light elements such as helium to the moon's surface and leaves them there.
Simple--and aesthetically pleasing--ideas include transforming Mason jars into solar-powered light jars, converting pallets into lawn furniture and reusing detergent containers as rain catchers.
Rather than creating a new type of solar-powered light, which seems to be where most alternative energy people spend their time, Martin Riddiford and Jim Reeves, London based designers spent the last four years developing GravityLight as an off-line project.
The owner had window film applied, followed by white "sheer-weave" motorized solar shades to filter light but leave the view intact.

This printing process is already used in organic solar cells and organic light-emitting diodes (OLEDs) that form the displays of mobile phones.
Now salt is back on the table as states such as California green-light big solar thermal power projects to meet ambitious renewable energy mandates.
While lunar daytime lasts around two weeks, and it may be possible to funnel this light into greenhouses, the current limits of solar storage technology are incapable of sustaining artificial light for the equally long lunar night, even with one of these guys helping out.
Rare earths are in CFL light bulbs, solar photovoltaics, and dozens of other devices environmentalists want in the energy mix.

Thanks to this program, villages without any infrastructure throughout the world are being helped to generate light thanks to solar devices.
Philips, for instance, is planning to launch a small solar-powered LED reading light for Africa, where an estimated 500m people live without electricity.
Solar cells, which convert light to electricity, have long relied on silicon, the same material upon which companies such as IBM and Intel build computer chips.
The near-infrared photoactive polymer absorbs more near-infrared light but is less sensitive to visible light, balancing solar cell performance and transparency in the visible wavelength region.

It's pretty rare that a portable solar-based device offers much more utility than impressing your friends, but PiSAT Solar's K-Light won't only make you the coolest kid on your block: it might actually prove useful the next time you take a hike or find yourself hanging out in a developing country.
ENGADGET: PiSAT Solar's K-Light boasts a one-to-one charging ratio
The conservatism of REIT managers has most likely already proven a barrier to some potential solar installations on REIT property, and a positive revenue ruling would have the added advantage of giving a green light for existing REITs to install solar on their property.

The first, called Kepler-34b, orbits its two small stars in a solar system about 4, 900 light years from Earth.
Instead of being flat, the glass is slightly wavy (somewhat like the glass a shower stall), which more effectively focuses the light on the underlying solar cells.
FORBES: U.S. Army Dedicates World's Largest Low-Concentration PV Facility
After all, China has a history of playing fast and loose with existing trade agreements by unfairly withholding rare earth materials from markets, and unfairly subsidizing their emerging markets on everything from light vehicle tires to solar panels.
Current solar power largely ignores near-infrared light and wastes about 40 percent of the potential energy it could harness.
Abertay University in Dundee is to be turned into the set of a giant light show based on the solar system.
Theoretically, Filler said, if some fraction of the LED were projected backwards into the system, embedded solar cells could capture some of that light as well.
In the top diagram the solar panel is completely exposed to a light source 1804 and all six electrode quadrants 1802 are producing electricity more or less equally.
