Not a typo. Folks at MIT have succeeded in powering a light bulb by electricity transmitted through the air. No wires. No wires AT ALL.
To me, this is amazing, science-fiction, world of tomorrow, type stuff. The idea is that eventually you could power all the electrical items in your home without wires, in much the same way that you can get an internet connection via WI-FI. So no more batteries, no more a/c adapters, no more chargers, for the cell phone, the pda, the laptop, the camera, the remote, etc. As long as you were close enough to a transmitter (or whatever they end up calling it), your stuff would just work.
I really really love this idea. And I love that they made it work. Now where the hell is my teleporter? I want MIT to work on that one.
