WiTriCity - It’s Wireless Electricity

Imagine This: You walk into your house at the end of the day’s work. You keep your discharged cellphone on the study, open your personal laptop and start checking your personal e-mail. Within an hour your computer signals that the battery is running out. Next, you just walk over to the only switch in your house and switch it on and voila your phone, laptop, camera and any other power hungry device that you ever owned starts to get charged.

Welcome to the World of the future, a world powered by

MIT researcher Martin Soljacic and his team have shown that Wi-Tricity would someday indeed be possible by lighting a 60-watt light bulb with energy sent across a seven-foot gap. Soljacic began his search for wireless transmission several years ago after being awakened by the beeping of his uncharged cell phone. “It occurred to me that it would be so great if the thing took care of its own charging,” he said.

The system, dubbed WiTricity, takes advantage of the tendency of objects that resonate at the same frequency to pick up each other’s vibes. Just as the strings on an acoustic guitar vibrate in the presence of notes played on another guitar, so energy can be sent between a transmitter and a receiver with the same electromagnetic resonance. In its trial run, his receiver was able to use about 45% of the energy transmitted. Because the energy can only be accepted by a receiver with the same electromagnetic resonance, excess electricity is absorbed by the transmitter rather than being dispersed into the environment. Forty-five percent might not seem like much, but it’s more than has ever been sent before. At this point, he says, the system works, and simply needs to be refined. (Source)

Well, it’s been quite a while since Solijacic and his team lit a bulb wirelessly and since, there have been no new updates on this front, it seems that the guys at MIT are definitely onto something big. Well, guys we really want you to make it happen and give us a would that looks like this :
