Wireless Electricity

In my ongoing quest to find an interesting investment in the alternative energy space, I came across this thread: Slashdot | Wireless Electricity Set to Power Village Mostly the complaints about beaming energy using microwaves are around the potential detrimental health effects. I have seen another company doing something on a much shorter range (like a couple feet) but forgot the URL. It was basically an invisable powercord. Powercords are not hard enough to find to fix the short range problem.
But power to mobile devices is a HUGE problem. The main thing holding back mobility is power. Now the question is really around does battery life get long enough to be useful before someone figures out how to deliver power wirelessly?
