Counter Rotating Coaxial Cylinder HPG

Here's a drawing for Illustration Purposes only so we can design a system with this concept in mind.  I look forward to your new idea.

Broli,

Your design in post #16 is a neat concept.  It is really thinking outside the box.  I like it, even though it doesn't defeat our enemy.  This has really taken us into a new direction with the HPG/HPM.

Here's the idea I thought about.

Basically in your first design you reversed the emf by having two discs rotating in opposite direction, but this implied having a counter torque since magnet and circuit weren't attached.

In this idea we rely on the fact that rotation reverses velocity for us with the given magnet. As you can see this concept is very easy to build. To me this should work unless physics says otherwise, if it doesn't work I would happily say I don't understand why. Since there's no apparent relative movement it might not seem promising, but if you follow homopolar analysis it should produce an net emf. Since rotation produces a velocity (yellow) of the mobile charge and these then want to attract to the center of the magnet on one side and repel when they cross the center. And vice versa on the other side AND even on the edges (bridge).

You're right, it doesn't have a counter torque in this setup.  I'll give you the bad news first, then some really good news which you must read.

I don't think it would produce a net EMF due to no net relative motion.  Here's my reasoning on this.  Let's say you have another radial magnet on a separate axis and they're both facing each other and you rotated only one magnet.  The stationary magnet would couple to the rotating magnet, similar to how the "magnetic stirrer" works.  This is due to the magnetic field rotating with the magnet and the conductive plates wouldn't be cutting the flux.  The radial magnet isn't spinning on it's magnetic axis so the field rotates with it.  Don't give up on this idea though, because it may be able to be exploited.

Here's how.  All of our attempts have failed possibly due to the HPG creating a constant DC.  Let's focus on having it create AC.  On one side of the radial magnet, we'll have an alternating EMF that is always opposite in direction to the alternating EMF on the other side.  Each side will be alternating 180 degrees out of phase with each other.  This will allow an alternating EMF to be generated with no counter torque without having the circuit and magnet attached to each other.

So, we'll replace the axial magnetized magnet in my original design with the counter rotating discs with a radial magnet.  The radial magnet will be able to freely rotate on bearings, but the counter torque on each side of the magnet will keep it from having a net rotation while generating an alternating EMF.  The magnet will be oscillating back and forth with no net rotation.  The faster the discs rotate, the faster the magnet will oscillate back and forth. The magnet should absorb the counter torque without transferring it to the discs which are connected to the drive axles.  This is a combination between regular induction and the HPG.  Unite the two together and everyone is happy.

What do you think?

The radial magnet isn't spinning on it's magnetic axis so the field rotates with it.

Yes this is the mystery to me. If this doesn't work then for some reason the homopolar forces I have been using to analyze these don't hold anymore. You could explain it with flux and field lines but I stopped using those concepts and only looked at movement and mechanical forces. For instance how come when a magnet is rotated around its magnetic axis it produces an emf but when you use the same force law and apply it to the concept above it doesn't anymore. When rotation happens the electrons on the plate get a velocity component, this velocity component should be parallel to "current" loops of the magnet and thus attract or repel t/from the center. Yet this probably won't happen in reality as you state.

Maybe you should draw that.

I'll draw a very basic idea based on this and ask you what you think will happen.
