There's still a freaky buzz on 4644kHz. And there's something that sounds like a movie ray gun on 4666.

Plenty of freaky shortwave left...

Blue starry one excellent in Chrome (3.0.195.38), somewhat choppy in Firefox (3.5.7), consistent with sopssa's comments above... What are you using?

My unofficial lab motto is "success without death..."

Entanglement, no. Tunneling, yes... if you like to market your device by insisting on quantum descriptions of things that involve transition rates of 10^28 photons per second. A ~10MHz photon doesn't pack a very big punch, energy-wise.

It's a classical effect but can be framed in quantum terms for "welcome to the future" cred.

It's not only possible, but really damn easy to do.

You can build a reasonably efficient resonant power transfer doohickey in your backyard out of some copper tubing, some low loss tuning capacitors, a RF power generator, and some diodes and filter caps on the far end to turn the received RF into DC.

I've built one to couple 4MHz pulses across to a rotating experiment for ultrasound measurement: http://n3ox.net/files/us_ring.jpg

You couple 'em that tightly, and they're like 99% efficient at transferring power.

But even with Tesla aside, this isn't new... it's just not as vastly useful as people re-discovering it seem to think it is. It doesn't work over gigantic distances, only moderate ones, and there's no engineering you can do to get around that. It's near-field coupling between resonant circuits. That said, I think it might end up pretty useful for non-contact charging of your electric car like TFA suggests. That's a *good* application for it, and it has more efficiency than "ordinary" inductive coupling.

Except that energy transfer is not information transfer, and doesn't really require any bandwidth. Of course, every emission has *some* bandwidth due to noise, etc, but you should be able to do wireless power with very narrow band oscillators and I suspect you have confine emissions to the the ISM (industrial, scientific, and medical) bands. Maybe it needs a little bit of slow digital transmission if you need to sync devices and chargers beyond just whether or not there is another resonant device around (you don't want charging stations trying to feed power to each other).

But the fact of the matter is that resonant power transfer requires sharply resonant circuits, so you can't emit much power over a wide bandwidth even if something goes wrong.

All you need to do is devise a complex computer with some decision making abilities and program it with information with destination coordinates in case it gets lost.

Program it to recognize a local authority figure like a policeman or teacher and provide them with the destination information so that they can help it find home.

I suspect the most effective hardware platform for such an application is some sort of fairly high-functioning biological organism.

You can shave 10 seconds off if the computer knows someone's going to walk up and boot it soon...
