Prototype Nokia Phone Recharges without wires

Today I just saw an interesting news, it says Nokia has taken another baby step in that direction with the invention of a cell phone that recharges itself using a unique system: It harvests ambient radio waves from the air, and turns that energy into usable power. Ultimately, this technology aims to convert electromagnetic waves into an electrical signal, somewhat similar to RFID (Radio-frequency identification).

Is that cool!

Wireless Power! Wireless Charging!

Here is the details for that article:

Mind you, harvesting ambient electromagnetic energy is never going to enough electricity to power your whole house or office, but it just might be enough to keep a cell phone alive and kicking. Currently, the boffins at Nokia have already developed prototype devices that are able to harvest up to 5 milliwatts, although this amount isn't enough to juice up a handset just yet with Nokia's vision of producing 50 milliwatts being quite a ways off in the future. Nokia says it hopes to commercialize the technology in 3 to 5 years.

Let's see!
