Omnibus this is a lie:

Wesley Snyder?s device proves it, Walter Torbay?s device proves it.

THEY DO NOT DEMOSTRATE OR PROVE ANYTHING AS BOTH DEVICES ARE NOT PROVEN TO WORK AT ALL.

This is the last post I read from you.

On the cotrary, this is a lie:

Let us wait and see which motor will really work.
As we now have a firsthand report witness in the Torbay thread (from gnn.tv),
this motor is working.
And yes, if magnets are glued together in repelling mode, they
discharge quite a bit after some time, so the optimal principle
is the Sprain design with just attraction of the magnets.

The Torbay motor would probably also work with attraction
when redesigned...

Stefan, how much energy (approx.) do you think is needed to magnetize a 10 cm^3 rectangular ferromagnetic piece from scratch to, say, 1000 gauss?

Also, let me add, Sprain motor is not self-sustaining.

Normally they magnetize these pieces in putting it into a big electromagnet into the airgap
of its big core and give the electromagnet a big kick from
a charged capacitor bank.
The magnetic pulse then is only about a few milliseconds long at maximum,
but this magnetizes the material for its whole life, so the energy spend
for the magnetisation is probably only a few Wattseconds.

Also, let me add, Sprain motor is not self-sustaining.

Not yet, but soon.
