But even with Tesla aside, this isn't new... it's just not as vastly useful as people re-discovering it seem to think it is. It doesn't work over gigantic distances, only moderate ones, and there's no engineering you can do to get around that.
The misunderstanding a lot of people have is that they think Tesla was chasing *truly* wireless power - when in fact this was probably never his goal. Tesla was always chasing after something he called "longitudinal waves" in an attempt to perform worldwide "wireless" power transmission - he even called one of his companies World Wireless.
Tesla certainly wasn't foolish enough to believe this distance was possible with purely wireless transmission, but instead investigated single-wire transmission systems using the ground as the single wire. His initial success at single-wire transmission was at Colorado Springs in 1900 with three lightbulbs in a closed circuit loop with no power source and a transmission source a hundred feet away. In this experiment, as in his later vacuum tube powering experiment performed at considerably greater distances (eventually miles away), the objects in question were always had a metallic contact with the ground.
Take a look at figures 3, 6, and 7 on this page: http://amasci.com/tesla/tmistk.html. This seems the most likely explanation for the experiments at Colorado Springs and Wardenclyffe. Wardenclyffe in particular is where we find Tesla sinking iron rods 300 feet into the ground, burning out local power station dynamos with his energy demands, and constructing a massive omnidirectional transmission tower.
The reasonable conclusion from all this is that Tesla was always pursuing single-wire transmission schemes in which literally the entire Earth itself was the single wire, and the transmission medium for the wireless component was the entire ionosphere. "World Wireless" seems to have been meant quite literally, which was in keeping with all we know about Tesla's personality. Unfortunately, as we all know, Tesla needed something like an order of magnitude more funding than JP Morgan was willing to provide - particularly after Marconi.
Beyond that, though, Morgan would have probably pulled the project even if Tesla had gotten it working: if single-wire worldwide transmission was in fact his intention, it would've been impossible to meter consumption on a per-user basis.
