Oh no.

Please. Let this concept die, and STAY DEAD.

Wireless transmission of power is useless. You have IMMENSE losses. I can guarantee you that powering that 60W bulb requires a whole lot more than 60W of power at the transmitter. Guaranteed purely by the laws of physics: namely, the inverse-squared law.

Oh, and, then there was the electrified ground that can come from this. Imagine walking everywhere you go with that distinct tingling sensation everywhere. Ions and ozone would be floating throughout the atmosphere everywhere. You do realize that both ionic gases and ozone are poisons to humans, right? And god help you if you somehow discharge a spark in the middle of a paint factory. Or a flour refinery. I hear those let off spectacular light shows.

The effects on wildlife should be interesting, since numerous creatures rely on their natural ability to detect the Earth's magnetic field for their own navigation. This oughta be fun.

While I'm not one to dismiss Tesla's creativity out of hand, this is singularly the STUPIDEST idea EVER in the history of man's exploration of electricity and magnetism. The health risks are immense, the risks to nature are immeasurable, and the energy efficiency of the system drops asymptotically towards zero the further away from a transmitter your devices are. And, even then, unless your receiver is a cylinder wrapped around the transmitter itself, the efficiency can never get above 15% or so, for the simple fact that your receiving antenna is covering no more than that amount of surface area of the transmitted power wavefront.

They should have consulted, at the very least, an licensed amateur radio operator, if not a professional RF engineer before considering this.

Good Grief, this was high school science fair material 50 years ago. What was Intel thinking?

I'm sure the idea has SOME practical use.


While it will never have even as much range as Bluetooth, at least you could drop your cellphone on your desk and know it would be recharged by morning:

And while the inverse square law applies, if the distances involved are, say, six inches...

and if the intent is to recharge a portable device...

and if the field only activates when a compatible antenna intrudes on it...

Well, it would sort of work.

But think of the applications that currently are impossible WITHOUT transmitted power...

What applications would that be, you might ask?

Imagine tiny surgical nanites, swarming through the body of someone who's had a stroke.

Imagine them administering really strong anti-coagulants right into a blood clot.

Or swimming to an injury site and cauterizing a potential aneurism before it blows.

Now, where will these nanites get their power? Lithium cells? No !

I've thought that you could build a tiny fuel cell that ran on blood glucose.

But hey, while that's intriguing, this remote power thing is available NOW.

If INTEL can beam sixty watts six feet, using nanites to target and kill cancer cells would be a cakewalk.
