Nokia's Teslaesque wireless power research
Nokia's trying to figure out how to scavenge ambient radio waves and convert them into power for phones.
The trick here is to ensure that these circuits use less power than is being received, said Rouvala. So far they have been able to harvest up to 5 milliwatts. Their short-term goal is to get in excess of 20 milliwatts, enough power to keep a phone in standby mode indefinitely without having to recharge it. But this would not be enough to actually use the phone to make or receive a call, he says. So ultimately the hope is to be able to get as much as 50 milliwatts which would be sufficient to slowly recharge the battery.(Thanks, Rossignol!)

I made one of those as a high school science project. it was a wide-band radio receiver with a huge honking choke that weighed several pounds. With a hundred foot antenna, I got a few micro Watts.
How they are going to get one thousand times as much power without a huge antenna, I do not understand, but wish them good luck.

Related to the "Teslaesque" nature of this...
There is an apocryphal story of Tesla creating an ambient energy collector to power a converted electric car.
Here's a Wikipedia article that debunks it.
The story may not be true, but it's believable. Tesla knew electric field theory better than anyone before him, and probably better than anyone since.

This is the best news I've heard all day.
Finally some REAL out of the box thinking from a big corporation.
