Beaming Power

By Deane Barker on April 2, 2007

Cut The Cord – Powercast Technology Transmits Electricity Through the Air: This is interesting because I thought that transmitting power through the air was the Holy Grail of energy. My understanding was that it violated several laws of physics.

A startup called Powercast, along with the more than 100 companies that have inked agreements with it, is about to start finding out. Powercast and its first major partner, electronics giant Philips, are set to launch their first device powered by electricity broadcast through the air.

It may sound futuristic, but Powercast’s platform uses nothing more complex than a radio—and is cheap enough for just about any company to incorporate into a product.

Whenever I’ve read about discussions of this type of technology, it always led to visions of “beaming down” power from satellites to remote villages somewhere. I suppose that’s a few orders of magnitude different than recharging your cell phone.

Thanks Greg.



  1. That is very interesting. Maybe this is a non-issue, but I wonder how the funding model for users would work? I believe users of electricity are still charged on a usage model, so how do I know I’m only paying for what I’m using? Maybe I need to sync up my cell phone with the charger in order to receive the signal, or something.

  2. Nothing new here. The trick is to make if practical.

    A 3 foot range is too short. The power output is too low.

    This isn’t ground breaking, its just another step towards the real goal.
