Nokia developing over the air phone charging

Posted: June 10, 2009 in Tech

Nokia is developing a smartphone that could recharge itself by harvesting power out of the air, more specifically from ambient electromagnetic radiation – emitted from Wi-Fi transmitters, cell-phone antennas, TV masts, and other sources – could be converted into enough electrical current to keep a battery topped up.

The Nokia Research Centre is working on a prototype device that could harvest up to 50 milliwatts of power from the electromagnetic soup – which is sufficient to trickle charge a switched off phone.

If successful, phone charging would be a thing of the past.
