This technologyt has always fascinated me. I have a lifelong fascination with Nikola Tesla's ideas and the man himself. It is already a known fact that electricity can be transmitted through the air. The problem is not technological, it is economic. The power companies have been buying up Tesla's patents and restricting research on "off the grid" power generation for decades.
Saw the Samsung commercial for the first time today. The one where you place your phone on a pad to recharge. Pretty cool I thought. I think that's definitely the wave of the future.
