THE ONLY REMAINING MOST LIKELY POSSIBLE CONFIGURATION WILL BE LIKE THIS:

This is straightforward. First we have reached the point were we can say with certainty that Steven is using a tapped median point on the left pole, therefore, regardless of the direction of the current in or out of these median points, he will have created 4 magnetic poles (at the front, back, left and right of the TPU).

How are the poles really oriented? How are the magnets oriented? How is he firing the coils? Let's study possible answers to these questions:

Steven says that his devices produces only DC. That to me seems pretty logical. Why? Well… because of the magnets which he places on the top slots of the TPU:

He is using two magnets one on the right hand pole and one on the left hand pole (conventional naming from the camera point of view, and from the wires that come out of the TPU).

If you are going to use permanent magnets, oriented like this, (with either south or north pole upwards or downwards), you must excite these coils ONLY WITH PULSED DIRECT CURRENT ! It's the only way it will work! Pulsed Direct Current is the only logical way!

So then, we definitely know he is pulsing the coils with DC…BUT HOW? Well…Here my research stumbled a bit. The most likely configurations are as follows:

This would imply that we start from the left pole as the positive lead, but we will end up with 2 separate ground connections which must be connected togetherand form one ground. Therefore our final, and only possibility will look like this:

This could be one very possible configuration for a working model, but it still has a long way to go. I intentionally did not mention an obvious construction detail until now, indicating the reason why he build it in the way that he did.

If you haven't yet figure it out by now, let's think about this topology for a second. We know from the Tesla transformer that it is extremely inefficient due to the fact that more than 80% of the field created by the primary coils is situated outside of the core, and can't be tapped, (although there are some implementations which use a rotor, inside the Tesla Transformer). So how can we close all the magnetic field lines, to increase it's efficiency? That is the correct and right question! The answer was found by Steven Mark with his clever and ingenious design:

You probably think that I've made a mistake and that the front pole in fact has no core. That's true, there is a junction box there, but again, you get the picture.

You might think that the top core disk is just for design. If so, then …you are so wrong… it's actually what makes this design unique!! It's what makes it work! It's the key to magnetic containment! It's how Steven Mark figured out how to return the opposing magnetic flux lines in the Tesla transformer through another one on top! The top disk provides the return path for the opposing magnetic fields created by the coils!

If you don't believe that the above picture is correct, then, first you must realize that everything up to now has been pure, sane, healthy, rational, fine deduction. NOTHING SPECULATIVE! NO GUESSING! NOTHING LIKE THAT! Read again, how I come to this conclusion from the deductions I made until now. Then to prove me wrong you must first prove that the above statements I made above are wrong. But hey, if you know a better way, why don't you write it down, and share it?

With this configuration we can proudly say: Outside magnetic field? In theory? 0!

Efficiency? In theory? 100% energy conversion.

So let's theorise a little bit now. If this configuration can have a core with a high permeability, then a primary winding and a secondary winding that generate such a field (four closed magnetic circuits), would have in theory above 98% efficiency. You might say that's ridiculous high and I'm forgetting about iron loses. No I'm not. Regarding this, iron loses are energy loses due to hysteresis magnetisation and demagnetisation of a ferrous metal. Right, but you have to remember that we are only working in the first quadrant of the hysteresis cycle!

it, that is in theory anyway.

Now here's another theory, what if we can provide an already existing magnetic field, in the same configuration and direction as the flux generated by the coils, so that we can raise above 100% efficiency? Wouldn't that be something?

I have come to believe that the reason Steven Mark is using permanent magnets might be the same thing as Charles Flynn does in his Solid-State Electric Generator:

This is another transformer, but which has a magnet in the middle. What's the point? The point is to manipulate the opposing flux fields generated by the coils with these magnets, to "reinforce" the field created by them, and to spend a little less energy in creating a magnetic field once you have one already from the permanent magnet. The Charles Flynn generator works in a different manner, but Steven Mark’s TPU is using magnets for the same reason.

If one of the TPU magnets has it’s north pole facing upwards and the other magnet has it’s south pole facing upwards, then the magnetic field created by them will bypass the front and back magnetic poles of the TPU:

There will be just these two poles created by the magnets (two magnetic closed circuits).

This configuration must be wrong, because of the direction of the magnetic field from the magnets with this arrangement. Half of the magnetic field would opposite the magnetic field created by the coils. Remember how those fields are orientated:

The coils change their winding direction at the front and back pole, so we have two magnetic fields in opposition in these places, and one of them will be also oppose the field from the magnet.

But by using them in repulsive mode, and orienting them so that they both have similar poles facing in the same direction, then their fields will look exactly like the one's generated by the coils:

So now, we have determined with a high degree of certainty how he orients his magnets in the TPU! This is where this deductive, and certain study ends, but it's not over. If, like me, you feel drawn to this type of technology, then please continue the work which I have started here!

I am going to continue further, but from this point on, please be aware that I am going to guess a lot, so the certainty factor will be greatly reduced.
