It's not a reverse solar panel. It's not a solar anything. It requires a difference in heat... So it generates electricity in the same situation that a sterling engine uses to generate motion. Could you put one on a diesel generator to turn the waste heat into more electricity?
Does it have anything in common with ~~those weird little solid state heat exchangers~~ Peltier elements? Wait, are they actually, literally peltier elements?
Or it's a panel optimized for exploiting infrared light.
