Base frequency of the TPU should be directly related to the magnetic frequency response of the control coils. If magnetic field in control coil changes too fast with the pulse there is no way magnetic fields of adjacent pulse coils will touch each other. While they should "flow" into each other in order to support rotating magnetic field. The only way to get this is to have magnetic absolute field intensity differentials of two adjacent control coils to be roughly equal halfway between the pulses - it is obvious that when magnetic field of one coil falls in intensity the magnetic field in the adjacent coil which was just pulsed rises. So, I would speculate that open TPU's two-ring frame is a ferro-magnetic material with a very slow response so that when the next pulse fires into the control coil there is still some field left from the previous pulse on the same coil. Then this magnetic field energy adds up with each pulse and may reach saturation thus limiting maximum output.

The "slower" the magnetic response of the control coil's core, the easier it will be to create a rotating magnetic field I think.

I think the reed switch/magnet is no more than a switch that looked cooler than a gaudy dangling toggle. Reeds have limited actuations and fail. I doubt Steven would have jeopardized demos over reeds getting close to their MTBF counts. And if magnets were of any value they would be deployed in the large unit.

For prototyping reed switches should be fine. Can you offer any idea of what could be used there instead of reed switches that also "pulse"?

Why does there need to be any mechanically induced switching or any electronic for that matter? At least one set of four coils energize in a circular or rotary fashion creating the gyroscopic phenomena in the physical world. Do the coils actually get mechanically or electronically switched? I don't think so. I do think there is a transfer of energy in a rotary fashion but how is the million dollar question.

Understood. If there is no pulsing going on, I'm out of here. And sorry to flood with my 'acoustic/phonon non-equilibrium' ideas. (but then again how this TPU is different from an AC motor then)

@All

I would like to mention that reed switches are available in both NO normally open and NC normally closed.

Essentially, all 6V auto radios used vacuum tubes and had vibrators to step up the 6V to HV for the plates.  Since SM started sweeping the floor at 13 in a TV repair shop, he may have stumbled across this vibrator concept and used it later in the first TPUs.  Actually these old HV generator vibrators are one of the coolest things I've ever run into.  Too bad I never had the chance to meet and talk to their inventor.  A DC/DC converter with no electronics from way back in the 50's.

Radio Shack would have had reed relays and by wrapping a coil around a reed relay he could have made a small vibrator HV supply.  This supply could also have had two HV outputs, one with a slight delay and a different voltage.  These two voltage waveforms go to the bifilar windings.  This transformer could be in one of the pillars holding the two plates together.

I definitely see two pillars with square ceramic magnets.  These could easily have wire wrapped around them.  Perhaps both Stefan and EM are correct.

To me the bifilar winding is made from ordinary lamp cord.

@Marco

The voltmeters used are auto ranging and if there is no voltage present on the input leads, the DVM switches to the most sensitive scale.  It is very easy to pick up noise from a TPU close by and get an indication on the meter on its 2V scale.  Therefore a reading on the meter when connected to nothing is not an indication of a fake.

Also SM probably had these square ceramic magnets in his pockets, lying around on tables, all over the place.  That one is lying on a table does not send me any alarms.

I noticed in one of the videos that after finishing a demo with one TPU he walks away from it, but before doing so turns it upside-down.  This indicates to me that there is an internal switch to turn off the internal battery [for the electronics or vibrator].
