Flat solar panels are becoming increasingly efficient, yet they do take up quite a lot of space. The Spin Cell could be a game-changer. On their website V3 explains that if one places a 20x solar concentration on a flat, static solar panel then the temperature quickly reaches 260 degrees F, the solder melts within ten seconds, and the PV fails. With the same concentration on the Spin Cell, the temperature never exceeds 95 degrees F. These spin cells produce 20x the amount of energy than the same sized solar panel. Maybe Bill Gates is right after all: our energy solutions will be solved through technology. i think these are actually quite attractive, certainly more attractive than most of the hideous mechanicals placed on rooftops in Manhattan.
