For the past few years, researcher Rabinowitch and colleagues have
been pushing the idea of “potato power” to deliver energy to people cut
off from electricity grids. Hook up a spud to a couple of cheap metal
plates, wires and LED bulbs, they argue, and it could provide lighting
to remote towns and villages around the world.
They’ve also discovered a simple but ingenious trick to make potatoes particularly good at producing energy.
“A
single potato can power enough LED lamps for a room for 40 days,”
claims Rabinowitch, who is based at the Hebrew University of Jerusalem.
