I read something about this sometime last year, same MIT project, so old news to me. But, from the article I read (which covered it in pretty good detail) seemed like a really good design. The design uses electromagnetic induction, however it's not in the same sense as you charge an electric toothbrush, instead of using a magnetic field at close proximity to get the electrons moving, electromagnetic resonance is used, and from the article I read it was a radio class wavelength/frequency. So I wouldn't worry about the extra radiation around, I would worry about wearing jewelry or other metal objects that would resonate at that same EM frequency :D.
yea, this is that same group and they finally made it work. last report they were still testing it out.

I remember that article too. Here on TPU I believe.

At any rate, I wouldnt be worried about radiation. Id just like it to be a bit further, perhaps 20 feet or so :).

In any light, this is an amazing feat and pretty damn awesome.

The next cool thing to invent is reversable gravity so we can all drive hover cars and bikes! WOOT

For small things, this could have some use. However on a large scale, I don't think this is happening, too much interference, issues w/ frying things, and what about the amperage? How is that going to power 2 HD 2900XT's in crossfire?

This seems highly inefficient for daily use. I mean, they make whole citys and states switch to energy-saving lightbulbs and now they fill a whole room with *electricity* so it can power devices which might be there.

I like the idea, like the inovation, like the progress but I don't see this happening in daily life.

id have to agree unless they found someway to beam it directly to the device instead of filling a whole room with it....for example have a type of dome like a security camera and then have it have like rotating transformers beam directly at the device automatically because of liek a homing beacon or something. like a little beacon that gives off a frequency that tells tyhe tranformers were to turn.

This is not new Tesla did this fifty years ago. Tesla invented electricity that you could stick your hand into but not get shocked but could power devices and be transmitted wirelessly a really long time ago. They may have prefected it but hardly did they invent it. here is one of the million threads that talks about it http://home.earthlink.net/~drestinblack/wireless.htm

here is a very cool web page http://www.teslasociety.com/
