This guy is from my home town. His name is spelled John Kanzius. Another invention under his belt which has received (I think) substantial funding is a cancer treatment that also uses high power radio waves focused into a beam. They are apparently not Xrays. By injecting the person with some sort of nano particle that binds to cancerous cells, he can effectively target only the cancer cells and leave the rest relatively untouched.

He is reporting that the salt water energy recovery is currently at 76% but is playing around with it to see what comes of it I think.
