A report in the current issue of MIT’s Technology Review features an interview with a researcher at Nokia’s UK research facility that indicates that the wireless phone manufacturer is working on a method for charging mobile phones by harvesting the electromagnetic waves that are omnipresent in the modern environment. Researcher Marku Rouvala indicated that like old-fashioned crystal sets and RFID tags, this recharge system would convert EM waves into an electrical signal. A wideband receiver would gather power from a wide swath of frequencies—from 500 MHz to 10 GHz. Rouvala was understandably vague about the details of this emerging technology, but industry analysts noted that such a technique if successful could have a tremendous impact on portable applications such as mobile phones and MP3 players.Check out the original article online.
