Considering there are new solar panels that used sphere shaped solar cells that can use reflected and direct light stunts like this aren't too surprising. If Toyota's Prius embedded these newer solar cells into the moonroof then maybe the air conditioning could be solar powered. The current Prius is a disappointment. It turns out the solar panels only power the fans that blow air through the vents, not the AC like Toyota originally said.
Fly it in Alaska during the winter and tell me you can have perpetual flight. Not going to happen. This is great, if you have a lot of sunlight. Like in summer. Oh wait, they tested it in summer, didn't they?
