WiTricity (wireless electricity)

Hello all,

Marin Soljačić ( A physics professor)  couldn’t sleep while his wife’s mobile kept beeping for low battery and he was so lazy to recharge it, So instead of taking a hammer to the phone, Soljačić marveled at the fact that this device, and billions of others like it, was sitting a few feet away from all the electricity it could ever need. Why couldn’t it receive power wirelessly, just as laptops get Wi-Fi ?

after alot of research Soljačić  learned that if you could get two magnetic fields to resonate , they could transfer an electric current. With two large magnetic coils, he transfered 60 watt wirelessly to  power a light bulb.

one would ask if it was safe to transfer electricity wirelessly ?

“There’s a real perceptual problem,” says CEO Eric Giler Soljačić’s  employer. “People think we’re putting electricity in the air, and that’s called lightning, and they know to stay away from that.”

In fact, the coils turn electricity into magnetic fields, then back into electricity. Magnetic fields interact weakly with humans; as far as the fields are concerned, they are no different from air. Giler makes a point of standing between the coils whenever he demonstrates the technology.

At the Nikkei electronics conference in Tokyo in October, he was able to power a 1,000-watt klieg light from across the room — a big improvment since the  first experment ..

“We’re going up the power curve,” he says. -Chris Taylor

In his presentation Chris Taylor uses his WiTricity to power a TV and to charge mobile phones….. really amazing

and he talked about how the pure electric cars are now easy to use. because you can put a device that charges the battery wirelessly in your garage and once you park your car in it your car batteries will be recharged automatically .

here is a video showing the WiTricity:

thanks for reading.

have a nice day
