According to Cnet, the Nokia Research Center in Cambridge, England is working on a prototype of a self-charging cellphone.
Oooh. Sounds really awesome, don’t you think?
For one thing, you’ll never worry about your phone dying on your while on an important phone call. So how does it work?
The system collects energy from ambient radio waves emitted by antennas, TV masts, Wi-Fi transmitters, and the like. Like RFID tags, the Nokia phones would catch radio waves across a range of frequencies, harnessing them for power.
Nokia’s goal is to get cell phones to harvest about 50 milliwatts of power. Currently the prototypes are able to harvest up to 5 milliwatts, but at least 20 milliwatts is needed to keep phones running in standby mode indefinitely without the need for a recharge – Cnet
So what do you guys think of a self-charging cellphone?
