Wireless recharging
this sounds interesting IF it works. its re-exploiting Tesla again (he was a genius) and is bound to have millions of uses outside and ipod or a laptop.. i have a power pylon beside me... mmm.. i wonder could i tap into that for free ... likely not of course

would probably give everyone cancer or something.
There have been lawsuits about cows getting cancer from high voltage wires. Now we're going to be deliberately shaking stuff at 6.4MHz... kinda scary considering.
Getting this to work across several feet would be exciting.
Of course the efficiency would have to be good. Wouldn't want to use a lot of power to charge wirelessly.
Is there some breakthrough I am missing? Can we finally deliver the current necessary to run devices not just charge batteries? That was Tesla's big problem too and I don't think these guys solved it. He found that in order to broadcast useful amounts of current, you would have to build a horrendously powerful antenna that was more of a problem that a solution.
I think the big deal here is about using non-radiative sources. The devices don't emit radiation so they don't require as powerful antennas. The waves stay on the source and just make big trails.

if by everybody you mean MORE than the one in 3 people that are already likely to get it in their lifetime?

he was! if anyone's interested here's the wiki, http://en.wikipedia.org/wiki/Nikola_tesla
it's an entertaining read.

i dont know, i just remember reading somewhere that people who live near power pylon had a higher chance of developing cancer.
