Wireless Power

Today, The Age is running a story (from AFP) on Intel’s recent demo of wireless power. It’s a great story, but it’s actually a year old. The original story is from June 2007 and was MIT’s demo of wireless power.

The demo involves lighting a 60W light globe across 2m, with 40% efficiency. If the technology could be improved to longer ranges, the applications are phenomenal. For example, you could distribute power throughout your home, and avoid needing batteries in any of your appliances or their remote controls. Or, you could distribute power with radio communications, so you wouldn’t need batteries in mobile phones. Or, you could distribute power across car-parks, so people who leave their lights on could still start their cars. Or, you could distribute power across an office, and people could work with with laptops anywhere, even if there were no power points. Sod that, you could distribute power into parks, where there are never going to be any power points.

The power cord is the “last cord”, as Intel says. I can’t wait til we can cut it. Safely, of course.

  1. Correction, Intel recently managed to do the same stunt with 75% efficiency, rather than MIT’s 40%

    Exciting stuff, and only 100 years after the Wardenclyffe tower. What incredible progress!
