Wait, where is the energy beyond the electricity coming from? Is it drawing heat from the environment, hence the references to heat pumps?

- vFunct 1y agoYep. It's taking environmental heat energy alongside electricity and converting to light.
- hinkley 1y agoSundiver! Holy shit David Brin was right?
- MrMid 1y agoExactly, it consumes heat. > ... took advantage of small amounts of excess heat to emit more power than consumed.
- Analemma_ 1y agoYes, it's drawing heat from the environment: the diode itself gets cooler as it emits light, and presumably at some point there's no more available energy in this way and so efficiency goes back below 100%
- thmsths 1y agoWhich is still amazing. An issue with high power LED is cooling. If this can be turned into a product, it solves the issue in the best possible way.
- thfuran 1y agoIt can't for high power LEDs.
- dzhiurgis 1y agoWhat if you point light into solar panel and use the power for LED..? Or point the light to space for a space cooler (IIRC I've read about something like this before).
- lordnacho 1y agoI think it is analogous to setting your tap to a teeny tiny amount of "on," and in doing so you entrain the existing droplets in your tap to fall out.
