This idea is really interesting. I wrote my own article about it for Media Life Magazine.

Bright future for MIT's wireless light bulb technology
Annoyed at the clutter of cables used to charge laptops, cell phones, BlackBerries and other portable devices? Those inconveniences may soon become a thing of the past. The frustration of plugging in his cell phone spurred scientist Marin Soljacic to develop new technology called “WiTricity.” According to a paper soon to be published in the journal Science, Soljacic and researchers from the Massachusetts Institute of Technology have succeeded in wirelessly powering a 60-watt light bulb from a device 7 feet away. Soljacic used the old scientific discovery of resonant frequencies to get his “WiTricity” to work. Once he found the correctly tuned wave, power flowed wirelessly into the light bulb. However, the technology has a few years before it makes its way into the market. Currently, the wireless transmission is not as effective as wires and batteries, and can’t broadcast farther than 7 feet. In addition, the copper coils that transmit the power are, at present, too large for user convenience at 2 feet wide.
