Phone Recharges From Radio Waves

July 7th, 2009

PhoneHere’s an interesting concept. You know all the power that radio and TV stations use to broadcast signals over the airwaves—most of which just dissipates away? This prototype Nokia phone uses that energy to recharge its battery. The power isn’t very much and won’t necessarily keep the phone fully charged while being actively used, but it would at least make the battery last longer between “wired” recharges. Expect to see this technology go live sometime in the next 3-5 years.
