Consider two large horizontal loops that are fed an AC signal of the same frequency. Depending on the phase of the signals sent into the loops, there will be either an attractive or a repulsive force for each half cycle of the AC waveform between the loops.
Put another way, there will be a push apart due to the positive half cycle and a push apart due to the negative half cycle of the AC waveform. Reverse the phase to one of the loops and instead of a push apart, the loops are in attraction.
This mechanical rectification of motion has always interested me, and is what allows Universal motors able to run in one direction despite the constantly reversing direction of current and voltage on AC mains.
Now vary the frequency of one loop just slightly off from the other and the effect will rotate the mechanical attraction or repulsion at the difference frequency around the loop.
Conversely one loop could be trimmed in length to change the standing wave into a rotating wave of attractions (or repulsions, depending on phasing) around the loop. This is a mechanical force that rotates around the loop if I am correct in visualizing all this.
Then all that may be needed is a way to have that mechanical motion translate into the motion of the electrons in the wire. Perhaps here enters SM's garden hose analogy,lifting the hose to produce a "hill" in the hose, which forces the water out one end. So we need not really a wave, but a hill (lifting the hose, and moving the lifted area along the hose). The mechanical rectification creates the "hill". Ordinary wave motion will not do the job as it will just force the electrons into the hills and valleys, but not move them along the wire. Pure wave motion would require a third frequency to modulate the wave to move electrons around the loop.
The loops could also be coiled up into multi turn electromagnets, but not rigidly fixed solenoids. The multi turn wire loops must be free to flex around the circumference in order to create relative mechanical motion between the loops and the circulating physical hill or valley in the wire.
Just thinking out loud, have not tried this, but it seems to explain the use of the very floppy wires seen in the early video showing the core being cut apart. Also this idea seems to explain the thickness of the smaller units when the loops are multi turn and coiled within that structure, but free to move relative each other, perhaps suspended in a foam rubber surrounding.
I don't believe we will see the effect if our windings are tightly wound on rigid formers, which prevent the relative mechanical motion of the loops.
It would also explain the mechanical vibration felt by observers, and the slight gyroscopic force. Study ring resonators and it will become clearer.
This effect was probably noted in SM's dual voice coil research, where one of the voice coils came loose off the former allowing a degree of freedom against the other voice coil.
It also occurs to me that if the excitation AC signal is capacitively or inductively coupled, the DC might be free to appear on the loops themselves, or possibly even between the loops if they remain electrically iisolated from each other.
Remember, SM was an acoustics guy, experimenting with dual voice coil speakers in an attempt to get a spatial sound field out of a single speaker. This would require phase information differences between the coils as well as another degree of freedom of motion (besides linear) in the piston of the loudspeaker
I wrote some of this up in the "Acoustic Resonator Hypothesis" a good while back but it was forgotten.
