Wireless Power

This entry over on Karlo's blog caught my eye... I think my rechargable toothbrush uses the same technology, since it manages to recharge itself on the base station with no exposed metal contacts at all, just some kinda Star Trek-esque proximity power transmission.

I seem to remember reading somewhere that people have tried to do wireless power transmission over large distances with microwaves - with the unfortunate side effect of frying any carbon-based lifeforms with cells who got in the way.
