MIT Unveils Sun-Free Photovoltaics View Articles
An anonymous reader writes "Researchers at MIT just unveiled a new solar power generator that doesn`t need sunlight to function. The button-sized power generator can tap energy from heat, the sun`s rays, a hydrocarbon fuel, or a decaying radioisotope, and it can run three times longer than a lithium-ion battery of the same weight. It is hoped that the technology may one day be used to generate power for spacecraft on long-term missions where sunlight may not be available." Read more of this story at Slashdot.
