WIFI CHARGER
Have you seen the inductance chargers that the folks at Touchstone market? You know, for use in the Palm Pixie and Pre? No hard connection there. It takes longer as the energy transfer isn't as efficient, but look Mom, no wires!
Stay tuned.
While wire-less charging *IS* catching on...
Motion-based charging is also catching on...
I personally doubt that there is enough juice in the airwaves to keep a phone charged.
Oh, also, a lightbulb takes significantly less electricity to light than a phone requires to charge and function. The rays are dangerous on the light-bulb lighting strength, and would be much worse on cellphone-charging strength.

The folks at Rca are working on a charger that will harvest the excess energy from wifi and possibly other EM emissions in the environment. Is this something that will work well in someone's home? Probably not, but in a busy urban environment, you might be able to get decent energy recovery.
