"Wireless" Power Transmission???

Can anyone comment on this video, purportedly demonstrating single wire conduction of power?

The actual demo starts at 4:07 minutes.

Just looks like HF discharge to me.

Very professional looking presentation with content of utter nonsense

Using the earth as a conductor is used in electricity power transfer, for nulling (if thats the correct term in English for the common return wire)

The other part of the presentation looks like a wireless transmission using tuned coils.

Very slick, could well get the attention of a few pollies and entrepreneurs. Technically it's garbage, the Tesla mob on the rampage again.

Don't you hate these polished presentations with NO basis?

I've designed WP systems for Medical Products and tested the prototypes. Recently, I designed WP for transferring up to 1.5kW for use in a home. so you can put appliance(s) where you want, untethered by cords. But, alas, MY presentations aren't polished, thus no investors! I'd like to tone down the power transfer and use it for lighting those low power luminaires, LED based? Then you could put lighting wherever you want it WITHOUT a cord, or wiring. How about at art shows, so you won't be limited by locations for the 'spot' lighting?

This WP is all based on magnetic fields and resonant linkages, of course. But, the next step should be something a bit more dramatic. Like, successful research at controlling 'ball lightning' Create a ball of energy here, move it to over there, and extract the energy for use, so it doesn't go anywhere else. Probably turn into a MAJOR weapon for the military, eh? Thoughts?

What's the efficiency like? I'd be surprised if you averaged 25%.

Remember that the transformer actually is wireless power with a 90%+ efficiency.

Hello Chris

Probably they need some money to refine the model. After some years of investigation they will figure out that they need even more money as sunspot numbers are lower then expected (or some other reason).

They "forgot" to scale down their Tesla Coils and wavelength with same factor as they did for their earth scale model. Now the Tesla Coils are satellite catchers.

Nice looking presentation for fools' day (1 April overhere). Hopefully they will not lure investors, or even governments into this idea.

One way of sending RF-power with a single conductor is the G-line

Imagine that the secondary is all sorts of objects all over the house and the rest of the universe.

Why imagine that, since the secondary is just the secondary? 

What you're referring to is the _load_ on the secondary, which can

Maybe they saw Solyndra, Fiskar, A123 etc. and wanted to be next in line for stupid handouts?

If the primary is making an unconstrained magnetic field big enough to couple to things like appliances in a home, it will induce circulating currents into any conductive stuff nearby, like wiring, plants, dirt, water, and people. All that will heat stuff up and waste power.

Wireless power works for really short-range low power stuff, cell phones and toothbrushes.

the worst could be a 'wedding ring' finger! OW!

Actually not as much as you might think, since these things are NOT in resonance.

Remember the transfer is not straight through, but 89.9 degrees out of phase.

yep, and has to meet all the FCC and SAR limitations.

However, even a person standing in the field does not absorb that much. Surprised me too.

oops, forgot to answer your question. Design goal of 90% Breadboard design goal 92%

A few years ago MIT made a big deal about inventing some resonant wireless power technology.

Yeah, here's a typical blurb:

which is hilarious. MIT continues to be in the forefront of absurd scientific breakthrough press releases.

MIT was happy to press release at 20%.

There is no such thing as an "unconstrained magnetic field" when 
dealing with transformers, even air-cored, if the secondary is loaded.

Of course it isn't. Wireless power transfer isn't done at 60 Hz. There's heaps of power oscillators and resonant coils involved.

and the secondary is

You missed the point. Most of the power gets lost. Even MIT, after 6 or so years of fiddling, is claiming 20% power efficiency. That's 80% loss. That is NOT very Green.

What blather.
