Our 40 inch TV at the living room is hooked up with tons of entertainment gadgets, our PS2, WII, DVD player, and the VHS are connected to it. You can images how they look behind the TV, not so good.

But an electric company called Witricity based in the United States developed a new line of technology that will allow us in the future to power up our TVs without any wires.

“Welcome to the world of wireless electricity” said the company chief executive Eric Giler, who also indicated that the new technology could one day replace batteries as well as conventional power sources.

The company demonstrated the wireless electricity on T-Mobile G1 phone, running Google’s Android operating system, and the iPhone. Wireless electricity is achieved through “electromagnetic resonance” which is physical phenomenon were objects with the same resonance frequencies can transfer energy between each other. “Resonant Magnetic Coupling: Magnetic coupling occurs when two objects exchange energy through their varying or oscillating magnetic fields. Resonant coupling occurs when the natural frequencies of the two objects are approximately the same.”



WiTricity power sources and capture devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field. These proprietary source and device designs and the electronic systems that control them support efficient energy transfer over distances that are many times the size of the sources/devices themselves.
