The idea of wireless energy transfer has been around for a number of years, but now MIT believes it can be done inside the lab
Massachusetts Institute of Technology (MIT) researchers
have created a system that is theoretically able to power electronic devices
wirelessly. Assistant Professor Marin Soljacic of the Department of Physics and Research Laboratory of Electronics, along with MIT graduate students Aristeidis Karalis and John Joannopoulos, are working on the "evanescent coupling" technology.
The primary downfall of other power-over-air technologies is the fact that they are extremely directional or extremely dangerous. The first roadblock in wireless power is traditionally solved by simply increasing the power and using omni-directional antennas. This unfortunately gives rise to the second downfall; enough of an increase in power to make omni-directional useful traditionally results in so much energy trasmitted that it is no longer safe for humans to stand near the device.
Soljacic's team attempts to solve this problem by building an antennas that create electromagnetic fields that resonate at particular frequencies and loop back into the device rather than completely emit out into the atmosphere. When two of these antennas operating at the same frequency have resonance loops that collide, one large loop closes between the devices and high power transmission can begin over the new electromagnetic loop.
The technology, at least in theory, should work at distances of up to five meters. Unfortunately, the team has not yet constructed or tested the system -- even though computer simulations and theoretical calculations both suggest that it should work.

I've read all this stuff before. I've read all that stuff by Tom Bearden about Tesla Howitzers and the Russians shaking the Earth with Scaler EM waves. The information is all there and I have seen it, but for anyone with the slightest critical scientific mind, its all too easy to see the flaws in this stuff.
Its rubbish that is based on some science and blown off into some crazy sci-fi conspiricy world. Tesla's experiments weren't in fault. They did work, but he wasn't producing longditudal EM waves. The eivdence of this is all too easy to find and, more still, all to easy to reproduce if you happen to be an electrical engineer.

I have to /agree with Helbore on this. I have studied up on Tesla, and the guy was most definitely a super genius, rivaling Einstein, and at least equal to him, though Tesla was considered more insane.
I haven't read all this conspiracy theories about scaler EM waves, but it sounds like a ton of hog wash to me.
