And what happens when you place a conductor in a changing magnetic field?

IMO:
At the frequencies they use think of it as using a giant cell phone. Sure, they aren't using cell phone frequencies but the frequencies are not what our bodies can accept. I think there will be energy transfer to our bodies as well.

Longitudinal? No doubt.

"No doubt, yes", or "no doubt, no"?
Non radiating mag fields, is that another word for scalar B?

I think it can be compared to tesla's wireless energy through the earth, but only using magnetic fields. The devices need to be tuned to the frequency, but what about things with a harmonic or aliasing resonant frequency, those also will (partially) resonate.

[BEP]

No doubt yes.

I think they have it wrong. The radiation should be in the form of pressure waves.
Yes, the receiver must be resonant to the pressure wave. If I'm correct we are talking about a very narrow tuning range.
Agreed, power transfer should be almost zero for untuned circuits.

Harmonic, subharmonic and aliased should also receive. My concern is the possibility of anharmonic results.

[alan]

anharmonics, like those of harddisks

I find this mag. pressure or scalar wave hypothesis very interesting, but know too little of it, only that it is like sound in a medium or pressure waves in water.
Got more info?

[BEP]

Pressure waves....  Just think of it like sound waves. The oddities are source to receiver distance and matching resonance is key. Unlike transverse amps and volts stay together (no leading/lagging) so power only appears while in the peak.

Use HF/VHF and those nodes are narrow.

Plenty of stuff on the web. Most of what I know comes from my bench.
