Homopolar torqueless gear generator.

Nope, not if the polarity is as shown. The left disc is torqued by the right magnet and left magnet equally and so is the right disc.

I agree but it doesn't change anything, each back torque being opposed to each torque. You have nothing else than two conventional Faraday disks, magnetically independant, electrically in series, and mechanically coupled.

I think you have the fundamentals wrong. Do you actually know what causes the back torque in a homopolar generator? Or do you assume it's some witchcraft that you don't need to understand?

You think wrong.

As I say that a homopolar generator works according to conventional laws of physics, it is only you who imagine witchcraft.

A Faraday disk can be used as generator or motor.

In generator mode, the Lorentz force F=q*v.B makes the electrons flowing radially. We can rewrite the equation by using preferably the Faraday's law: (1) e=B*(dL.v) where dL is a radial segment, v the linear speed of electrons, both being vectors and their product is vectorial. Here v and dL are perpendicular.

In motor mode, the easiest way is to used the Laplace's law which here gives the tangential force acting on a current element dL: (2) dF=I*(dL.B). dL and B are also vectors and perpendicular.

Now if we loop the external circuit in order the generator disk to provide a current, from equation (1) we get the current I that is drawn: I=e/R, R being the resistance of the circuit.
We put this current I in equation (2) in order to get the counter force which generates the counter torque. And by simply integrating along the radius the product of the force dF by the distance from the disk's center, we get the counter torque.

What you missed is that as soon as a Faraday disk is used as generator and a current is drawn, then the current makes the Faraday disk to function as a motor whose torque opposes the  torque you apply to rotate the disk. Both phenomena work together.

The fact that you group 2 disks doesn't change anything in the fact that the two counter torques still apply to each disk. If you are unable to understand the theory, you should build your "invention", make a real device, and observe what will be going on (nothing new), instead of providing a pretty but useless cartoon.

I don't know why I bothered responding. It's not like you have a reputation of constructiveness and open mindedness. For your to lecture me on homopolar theory using wikipedia is an insult. So do us both a favor and just ignore this thread.

The homopolar generator is another experimental proof showng what dead-end mainsteam physics is in. That can be seen at once -- Maxwell's equations cannot derive the voltage produced by the homopolar generator and they should if they are truly the equations describing the electromagnetic phenomena. To escape from this obvious defficiency the mainstream is foisting on us that said voltage arrives from the Lorentz force. Lorentz force, however, has nothing to do witeh the Maxwell equations, it cannot be derived from these equations.

The sorry attempt by Einstein to derive the Lorentz force from the Maxwell equations (by using Lorentz transformations, transformations both unphysical and having nothing to do with his unfortunate "theory") fails miserably, as can be seen in his 1905 paper by inspecting paragraph 6 of said oaper.

Thus, at present, physics is in a very bad crisis and a dead-end, the result of the lies and manipulations throught the entire 20th century. The only hope for it to recover its integrity is in efforts such as these in forums like this one, no matter how much of a fringe science it may appear to be at present.
