tubes can handle those voltages more readily than semiconductors, speed is also a factor. Maybe even the flux fields affect on the semiconductors.

Now what if the core is just a bundle of copper wire and the neo magnet supplies the magnetic field? This allows us to start and stop it, no?

Look at the pix of the open frame unit, thoise are stacks of ceramic magnets right? The cylindrical object might be a starter or even a DC motor that provides the smaller pulses (brushes creating the spikes), the larger spikes from a voltage multiplier? According to the patent the power is obtained froim the enhanced mag field and the spikes voltage differential.

The feedback coil is then the output coil perhaps. On the open frame unit the output is more than likely the 18ga speaker wire (that is a guess on the wire size).

Thoughts?

Correct me if I am wrong here , but isn't 10^-12 about 1 terahertz?

Like the pulses are so fast that lenz hasn't got time to establish before they're gone?

Tests have been carried out with different fixed values of the period up to a minimum value about 10-^12s

10^-12 sec ?? That is extremely fast isn't it?  Might that be why Steven Mark says to use tubes for the controller? Are transistors not fast enough.....hmmmm     What about Mosfets in avalanche...will they manage this speed?

A period of 10^-12 seconds equates to a frequency of 1 terrahertz.

Currently the only devices capable of achieving such frequencies would be based upon carbon-nanotube technologies, which are currently still under development.

Dyamios, you beat me to it!

For a POC, I think that we should try to keep the pulse duration as short as possible using cheap signal gen's (555's again?) and  drive the coils with a power transistor and vary the amplitude of the pulses from each generator, one at full power and the other say at 20%? Using 12vdc as the source to start with

Just read this bit again:

In a preferred embodiment of the present invention, the unit 120 generates a first voltage pulse sequence at its output terminals 125 and 135; the time interval (in the following indicated as"period") between two contiguous pulses (considering negligible their length) is fixed, and has a value related to the application and the structure of the electromagnetic device 100. Tests have been carried out with different fixed values of the period up to a minimum value about 10-l2s, but the present invention lends itself to be implemented also with not fixed periods.

They probably mean the delay between the two pulses (A and B as i named them). So it might well be that that they're genrated at the same moment but the B pulse is send through a delay line to time the 10^-12 sec delay...... Right?
