If you’ve gone shopping for mobile phone accessories recently, you’ve probably seen or heard about Powermat, an Israeli company that sells electronic pads capable of charging electrical devices wirelessly. Do they use sorcery? No, it’s something called inductive charging, which utilizes an electromagnetic field to allow electrons to “jump” a short distance from the pad to the receiver attached to the phone, MP3 player or whatever it is you’re recharging.
That’s pretty slick, yes, but would it be possible to scale it up to charge a bigger electrical device? Like, for example, a car? Turns out the answer is yes, and GM is already collaborating with Powermat on a system for wirelessly charging the Chevrolet Volt. Meanwhile, Fulton Innovation, one of Powermat’s rivals, is also working on a wireless vehicle charging system, and actually showed off the prototype seen here charging a Tesla Roadster at CES in Las Vegas.
