Filed under: Misc. GadgetsNanoelectonic devices have to have juice too, and thanks to a team at Harvard University, extraordinarily minuscule gizmos of the future could be powered via a "silicon nanowire that can convert light into electrical energy." The device itself is said to look much like a typical coaxial cable, but it's around 100,000 times smaller and shuns metal in favor of "silicon with three different types of conductivity arranged as layered shells." Reportedly, a single strand can output "up to 200-picowatts," which won't move much, but it could
