stupid question here,

that white wire that goes to the toroid in all his videos...
it is even in the cut outs of the big tpu's

is it litz or just regular primary wire

maybe they just had a huge sale on white and black wire where he bought his stuff?

And again,
That looks just like the SM17(Large TPU?) except there is only one of 'those things' in the middle / on top. The large loops are the antenna, for lack of a better term. The same rings that SM cut through. Nothing to them.

Which brings up an interesting point. Why cut them? Now it looks like something 3 fold.
1: The ignorant immediately gravitate to 'The big part! being focused on and cut' Oh my!? (Like that is the engine or main part.
2: Eligant social engineering. 'Don't look at the man behind the curtain' trick. Slight of hand prestidigiation.
3: The bigger part is not the real focus.

The mag coil thingys I have are on the bench. It is my firm belief that I can apply frequencis to these and watch what appears in the larger loop tanks. 2 items come to mind with this. I match the freq to the bigger loop or the freqs, the large loops, and the smaller mag amps all have to be in resonance or tuned to some harmonic.

And also, this has been stated before: The idea is to ping the tank at the right time to cause the swing to increase. In this case the tank is mechanically large in space / volume. Very much unlike what we see in circuits normally. I didn't even see it in Coral Castle till 1 year later!

My focus on that trip was matching what I knew about Keely up against what Leedskalnin had accomplished. And I did... but missed a few newer recent things.

1 more thing:
When looking at the posted picture above: If we lessen the diameter of the outer rings to have them circumnavigate under those smaller vertical windings we have the model of the 4" and 6" TPUs.

The upper and lower steel bailing wires look like "cut to length" signal delay lines.

1ns per foot.

Establishes the delay or phase between signals entering the real coil which is wound around the center of the spool.

Perhaps SM had to get the steel wire away from the real coil wrapped around the center of the spool.  Thank you for this keen observation.

I don't see any means of feedback via a field or space effect in this early version.  This unit may have no feedback at all.  The output was pretty low compared to later units.

Anyone see a collector coil or wire in this unit?

Any current through the core coil would appear to the transformer as a magnetic saturation of the core. 
*Unlike a saturable core reactor the core saturation is controlled by an active element not relying on a winding on the outside of the torroid to effect the magnetic field inside the windings.

This is the final clue! The GK4 exhibited this on a very dynamic and spaztic level. And this looks just like Otto's windings.

Hello all,

just to add my 2 cents to the hmmmm.....lets say confusion:

are really MOSFETs needed to pulse a TPU?? or are only little transistors good enough??

Are even little transistors needed to pulse our TPUs or is there maybe a natural frequency or something else pulsating at 245kHz or as Bruce_TPU said at 222kHZ, or another, lower  frequency and we have only to amplify this vibration with a set of coils??

No, please not from power lines because I dont have them near my house.

Otto

Yes, you used transistors, but did it work?
