Fujitsu Eyes Wireless Gadget Charging For 2012 158
angry tapir writes "Researchers at Fujitsu Laboratories have developed a wireless charging system that they say can simultaneously charge a variety of portable gadgets over a distance of several centimeters without the need for cables. The system, which will be detailed at a technical conference in Japan this week, could begin appearing in mobile phones and other products as soon as 2012, the company said. Fujitsu's system is based on magnetic resonance in which power can be wirelessly sent between two coils that are tuned to resonate at the same frequency."

Seems like any piece of wire and a diode will extract a trickle feed of power from the RF bath we live in. Why not just use that?
Because there is not enough, but I suppose you could market a mobile phone which you charge by putting it in the microwave.

But the Tesla coil is in there.
