Comment on LED's efficiency exceeds 100%parentComments−DougBTX14yThere needs to be a cold sink since heat is just a variation on kinetic energy (small vibrations), and momentum needs to be conserved. The released photons have momentum too, and it looks like they get that from the heat (=vibrations) in the LED.
