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.
