Bet J.P. Morgan is rolling over in his grave on this one...  Cry

Cutting the Cord
Perhaps the most practical of the concept products Intel debuted yesterday, the Tesla-esque Wireless Resonant Energy Link (WREL) could enable users to recharge their laptops or mobile handsets simply by being in proximity of a transmitter.

WREL is based on technology developed by a team of researchers including Marin Soljacic, assistant professor of physics, and Andre Kurs, a graduate student, at the Massachusetts Institute of Technology .

The technology consists of a source antenna and a device antenna, according to Kurs. "A special-purpose circuit takes power from a regular wall outlet and uses that to excite electric currents in the source antenna. Those currents generate electromagnetic fields and the device antenna captures some of the power contained in them and feeds it to the gadget that one is interested in powering," he explained.

"In order for this scheme to be efficient when the source and device are separated by some distance, it's necessary that both antennas be resonant at the same frequency and that they be carefully designed so that, roughly speaking, they transfer power among themselves faster than they dissipate it," Kurs told TechNewsWorld.

Intel's version of the technology consists of two parts. On one side is a transmitter, comprised of a dry loop and resonator with a coil and transmits energy. On the other side is a receive resonator and pickup loop, through which the device acquires the energy, said Sample.

Ok, so I'm a Tesla fan, or is that fanatic?
Either way, this sounds most promising.

So, if div E = - d B/d t
How can there be no electric field when there’s a magnetic field?

Don’t get your hopes up.

Don't know if this actually happened or was urban legend, but supposedly some farmer in Washington state had a metal-roofed barn that kept warm in the winter from the energy from some high power low frequency transmitter.  May have been LORAN or Omega, and the Navy took a long time figuring out why they had this notch in their coverage pattern.
