Intel: Laptops could get power wirelessly

It looks like a high school science project, but is actually the first step towards one day wirelessly powering your notebook or mobile phone.

The two coils pictured here are passing power between them. It’s only enough to power a light bulb, but it’s amazing to see, with no cables, coils or wires between the bulb and the power source.

The demo works using a “resonance” effect between two magnetic fields. While the demo saw 60watts over two feet, the technology is capable of much more.
While the coils are large, the next step is to minitiarise them so they can be placed inside laptops and other portable devices.

"Hopefully we’ll show the wirelessly powered laptop in the not too distant future," said Intel senior fellow Justin Rattner.

The technology could also be used to charge mobile phones.

"You could imagine having one of these on your desk and you might drop your phone on your desk and have it charged."

William Maher is reporting from San Francisco at the Intel Developer Conference.
