radio wave powered mobile phone

Looks like Nokia is planning to make solar energy redundant by makingcellphones that can be powered by radio waves. A prototype radiowave-powered cell phone is already in development at the Nokia ResearchCentre where it will be able to harvest 50 milliwatts of power which isenough to charge a switched off phone. If this technology works, thenit could be used for a variety of appliances like MP3 players and otherelectrical devices that use around 100 milliwatts of power. Nokia plansto release the technology in three to five years probably as an add-onto solar powered cellphones.
