"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery.
Physicists build circuit that generates clean, limitless power from graphene
My bet is that it's simply working off stray electromagnetic radiation - like an old time crystal radio.
ReplyDeleteI'd like to be wrong though.
