Nanoelectonic 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 be just enough to run ultralow power electronics that could be worn on, or even inside, the body. Hopefully they'll have this all ironed out by the time we need a pacemaker.[Image courtesy of Harvard]
That's actually really exciting. We need power to run all the medical nanobots that are going to keep me moving long after mother nature has given me up for dead.

What if they just increased the size (thickness) of the cable, then could it make more power? I'd make a pretty sleek cellphone charger!
How exactly to they get light, if they are inside of your body?
nanonuclear reactors powering nano light bulbs, obviously!
yawn. they did this 20 years ago with light-powered calculators. ;-)
This could be a full stop to all of our energy problems. Is it possible to make super efficient solar panels ?
