Wireless, non-radiative energy transfer will allow you to cut your power cables.
Here's how it works
Tesla started it. Intel and Sony are both interested in it. And a Croatian physicist and electrical engineer will likely be the first person to commercialize it. “It” is wireless energy transfer, and I’m betting that it will be commercially deployable in limited form by 2013. This means that the days of having to plug your phone in to charge it are going, going, and almost gone.
This accomplishment will be a holy grail of sorts. Ever since Andre-Marie Ampère codified the laws of nature—dictating that an oscillating magnetic field produces an electric field and that an oscillating electric field produces a magnetic field (Ampère’s circuital law)—history has been littered with theories and attempts to enable the wireless transfer of energy for the purposes of powering lights, objects, and devices.
