Light may be the most abundant resource on Earth and now it can be used to create electricity. The world’s first optical rectenna, part antenna and part rectifier diode, was developed by researchers at Georgia Tech to capture light and turn it directly into DC current. Wildly simplifying the generation of electricity, this crafty little device could really become a game changer in the field of renewable energy.
