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 was refering to his wireless car power experiment, you can read my post further up the thread.
I can only laugh at those that does not beleave in what have been shown working fine as i said he drove a car at 100 miles per hour with a famely member, for everyone to see, there was several newspaper adds about it and you can still get digital copies of those.
So i will just say it like i said it before.
Just because you cannot find information or just figure out how smth work, it does not mean that it is not nor that it does not work.
As a sidenote regarding health i would like to say, that if you could transfer the energy as a healty signal, like ELF multi wave, then it would actually bennefit those people in the way of the signal, so wireless power does not have to be dangeroues, it can be healthy also ;-)
Try searhing on Labovsky, antoine piorre etc.
Their machines work very well, last mentioned just a bit closed to public.
