Nokia has announced they are working on a new form of charging your cellular battery. Like something out of Star Trek Nokia is trying to pull ambient radio waves out of the air, and use it as the energy source to charge your cell phones. The RFID like technology is currently able to harness around 5 milliwatts. Nokia will need to get this to around 50 Milliwatts before they will be able to make use of this energy source for charging a lithium-Ion Battery.
