Scientests power lightbulb remotely with transmitted electricity!

Very interesting. They lit a bulb from 2 meters away through transmitted power with 40% efficiency using theories based on resonance.

Hooray for MIT boffins!

Interesting indeed. They'd better be careful where they point that thing! (Imagines all sorts of malicious uses which I'm not about to share in print.)

Tesla!

Tesla did that with flourescent bulbs decades ago. They still do it at the Museum of Science during their electricity show.

The key will be having it be quieter than a screeching Tesla coil!

I thought they already had this. Don't they call them "batteries"? :P

Anyway, sorta reminds me of this: http://www.thinkgeek.com/stuff/41/wec.shtml

That's MIT for you. Of course, if they can pick the efficiency and the ange up sufficiently to make it commercially viable, I can see a lot of portable devices being powered off a couple coils. Which is a fantastic, fantastic thought, indeed.
