Charge your cell phone by air?! Entrepreneur figures out how to do it

If tons of more things are running off of radio waves how bad would that impact our health? Any ideas?

This is great. I've been hearing a lot of buzz about this recently. I'm still wary about the effective power captured from the radio signals, but the article graphic throws out a figure of "up to 70 percent." That's damn impressive if reachable.

It's funny though -- a few years ago, I was having one of those late-night "what if" discussions with some friends. We were throwing out our best invention ideas for guaranteed fame and fortune when we began talking about cordless electricity (power through the air). We laughed it off, but I read up on it shortly after and found some interesting things. Fast forward to now and the advances in effective conversion is just awesome. For now the applications seem to be on the small-small-scale, but even then this is going to turn multiple industries on its head.

Reminds me of Nicola Tesla's holy grail. He conducted lots of weird experiments in the later part of his life to transmit power across the aether.

Wow just wow...think of the thing you can do with this technology. This could mean wireless power for pretty much anything that uses electricity.

No response? This is pretty much the holy grail of electrical engineering.

Seems a little too good to be true, but here's hoping.
