Homopolar generator idea

[F6FLT]

The voltage depends on the direction of rotation and the polarity of the magnet.
If on one side we see the pole N turning CW, on the other side we see the pole S turning CCW. So the effects are compensated, the voltage is the same on both sides.

No one has yet found a way to add voltages of a homopolar generator without going through as many sliding contacts as rotating elements, which is why we do not know how to make homopolar generators generating a high voltage, whereas it is very easy to do so with alternating currents, simply by increasing the number of turns of the coils.

The patent https://patents.google.com/patent/US6603233B2/en is an example of the increase in the voltage of a homopolar generator, but by the multiplication of sliding contacts. The sliding contact being the weak point of any homopolar generator because it is too resistive when the domain is that of low voltages and high currents, multiplying them multiplies the problems without innovating anything on the theoretical level (contrary to what its promoters say by insinuating violations of Newton's laws or relativity  ).

I made a test with a disappointing result

@F6FLT, have a design/mod/expansion of Teslas unipolar dynamo on paper.  It's brushless, strengthens its field as current is taken off, and you can add resistance to determine voltage.  I never posted or worked up cad drawings for it as i knew i wouldn't havd time to build it (other projects).  Also, didn't think it would get much traction either as it works on situation # 2 of the paradox where the magnets move with stationary disk.  If anyone is interested I guess i can whip up something in sketchup (trying to learn fusion/inventor), just dont expect it fast.

It must be understood that "sliding contact" is just a way of talking about an electrical contact between two conductors that move relative to each other.
Two counter-rotating discs that touch each other by their rim make a "sliding contact" in the electric sense, even if nothing really slides mechanically. Because I assume you're talking about Tesla's patent 406968. This does not derogate from the rule that a sliding contact is required every time you want to increase the voltage without increasing the speed. With two counter-rotating discs, the relative speed has been doubled, it's only a practical way to do it but it remains a classic homopolar generator with its two half-circuits in relative speed.

If your design is based on a different idea, even partly based on this patent, I'm interested and would appreciate that you give a description.

@Arne

Could you give a brief description? I don't really understand the principle.
