Although the idea was first postulated and worked on by Nikloas Tesla, it is now being worked on again, and perhaps this time it will succeed.

Death of the cell phone charger
A Pennsylvania entrepreneur has developed technology that gives you all the battery juice you need directly from the air.

(Business 2.0 Magazine) -- How much money could you make from a technology that replaces electrical wires? 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. A transmitter plugs into the wall, and a dime-size receiver (the real innovation, costing about $5 to make) can be embedded into any low-voltage device. The receiver turns radio waves into DC electricity, recharging the device's battery at a distance of up to 3 feet.

Picture your cell phone charging up the second you sit down at your desk, and you start to get a sense of the opportunity. How big can it get? "The sky's the limit," says John Shearer, Powercast's founder and CEO. He estimates shipping "many millions of units" by the end of 2008.

For years, electricity experts said this kind of thing couldn't be done. "If you had asked me seven months ago if this was possible, I would have said, 'Are you dreaming? Have you been smoking something?'" says Govi Rao, vice president and general manager of solid-state lighting at Philips (Charts). "But to see it work is just amazing. It could revolutionize what we know about power."

Wonder when there will be a Chinese manufactured version?

Great idea

I wonder how big the receiver would have to be to power my car?

Actually wayves, interesting question and it would appear at least possible - but perhaps in a slightly different way.

I remember years ago - think it is still in testing - there was/is and experiment ongoing in regards to cars being controlled by an electronic strip embedded in the roadway. The driver would manually drive to the appropriately enhanced road and then the car would be set to automatic. A connector would drop down from under the car to make contact with the strip in the roadway and computers would then control all aspects of the journey after the drive input their destination into the onboard computer.

Now, since there is already a connection with the roadway it should be rather easy for electricity to be drawn into the car batteries directly, thereby recharging the car so that whenever the driver does have to go manual their car will always be at optimum charge.

Down with using the decayed leftovers of long-dead reptiles!

Up with electricity!

Could be a T-Shirt in the making!

Why up?

Because it's been nearly a year and I haven't heard or read anything about it since early 2007 and wanted to see if anyone had any updates.

As well, there is some "color" in this thread that needs to be present after such a long absence.
