Finally, they're able to send electricity through the air. I'm not sold on the name yet: WiTricity
Goodbye wiresâ.¦ - MIT News Office
A team from MIT's Department of Physics, Department of Electrical Engineering and Computer Science, and Institute for Soldier Nanotechnologies (ISN) has experimentally demonstrated an important step toward accomplishing this vision of the future.Realizing their recent theoretical prediction, they were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The MIT team refers to its concept as "WiTricity" (as in wireless electricity). The work will be reported in the June 7 issue of Science Express, the advance online publication of the journal Science.

This is nice that more companies are getting involved in the wireless electricity revolution.
I know that a company called PowerBeam is also involved in the wireless era and they safely transmit energy through optical energy, instead of the copper wires and the electro-magnetic field.
By using optical energy they can send energy over long-range distances. Their device also has a safety system so that it shuts down if anything is close to the beam.
