Nokia works on phone that can draw power from radio waves

Yesterday, Samsung released the world's first solar-powered phone, and, today, Nokia announced that it is working on a phone that can harness the power of ambient radio waves, such as TV, radio, and cellular signals.

While the phone will not capture enough waves to power it during a call, it will capture enough to keep the phone powered when in stand-by mode (powered on, but not in use). The goal is eventually to develop a phone that can not only keep itself powered while in stand-by mode but also capture enough energy to slowly recharge its battery when not in use. Now, that would be cool.
