Intel Demos Wireless "Resonant" Recharging

Al writes "Last Thursday researchers from Intel demonstrated a way to recharge electronics from about meter away using a 'resonant' magnetic field. At an event held at the Computer History Museum in Mountain View, the researchers showed off a pair of iPod speakers connected to a 30-centimeter-wide copper coil that received power from a similar, but larger, copper coil about a meter away. The recharging technique relies on a phenomenon called resonant coupling, in which objects can exchange energy when tuned to resonate at the same frequency. A similar approach was developed by researchers at MIT in 2007, and spun off into a company called WiTricity. This company has already developed a few products that use resonant coupling to recharge, including a car battery."

Oh this is going to look cool

I'm having a little trouble here with the concept. Instead of small white box plugged into the wall we have these freaking huge copper wires running in circles everywhere. Just doesn't jibe with the trendy iPod image.

Can you imagine a Beowulf cluster of these things?

Just paint the copper wires white.

Did they ensure that the iPod speakers were properly shielded against RDF interference? Now that Jobs is getting his strength back, I fully expect that Apple devices will discard with batteries completely and just feed off his sheer willpower.

I saw a documentary called Iron Man where this was done.
