Prototype Nokia phone recharges without wires - Blogs - Yahoo! Canada Tech
Ok, the title is a bit misleading, but the tech is still cool. Nokia has a prototype phone that is able to scavenge about 5 milliwatts of energy from ambient radio waves. While not enough to power a phone under normal use, it might be enough to keep it from dying completely. They hope to eventually be able to collect as much as 50 milliwatts from ambient radio energy.
