Unplugged

This story makes me wonder what else our brains are going to have flying through them in ten or twenty years and what strange new forms of cancer we'll all be talking about because of it. Ahhh progress.

To summarize, a group of scientists figured out a way of sending power without wires. It uses the concept of resonance. A coil has energy running through it, and a coil with the same resonance is a few meters away. Because of resonance, the second coil starts filling up with the electricity being emitted by the first, and you can harness that electricity in the normal way, to power your cat-washing machine. They say there's about a 40% efficiency rating on the process. So I wonder if they can get that number higher with more tweaking.
