P.S. If that was no use, maybe try this ??

But I'm not sure if anything is actually referenced to the real me ! Doh !

The wheel could work, but I'd say, explore the phenomenons of the bi-toroid first, I think that is the most promising invention of yours.

THANKS FOR THE READ...

AND YES I AGREE THE BI-TOROID AND NOW THE MULTI-BI-TOROID WOULD MOST LIKELY BE THE BEST AND SIMPLEST OU DEVICES OUT THERE - THAT IS WHY I HAVE BEEN EXPLORING IT FOR THREE YEARS NOW AND WILL CONTINUE UNTIL IT'S DONE.

hi Thane,

Re on your spinning steel disk idea:

First I would suggest you make a test by rotating the steel disk you intend to use for the task in front of the magnets and make sure the eddy current heating effect is negligible. 

If you have excessive heating, then choices are you have to use transformer lamination-like materials or ferrite sheets to minimize eddy currents (unfortunately both the lamination and ferrits sheets involve mechanical problems to fix them at higher RPMs but it may be solvable).

I agree with alan first you are to improve the bi-toroid transformer (thinking of looping its output to its input when possible) and may the force be with you in all your efforts!

SO, I'M HAVING A 10" STEEL DISK MADE WITH 18 x 1" HOLES DRILED AROUND THE OUTER EDGE.

ON ONE SIDE WILL BE A STRONG MAGNET AND ON THE OTHER SIDE A COIL RIGHT AT WHERE THE HOLES ARE...

THOUGHTS?

Your earlier rotors had some of this effect with the magnet in a cup. This is called a pot magnet for
those not familiar with the term.

But if the magnet is too far back nearly all the flux will be shorted through the rotor. Possibly if the
hole was bigger and the magnet was brought through the hole somewhat so as the BLOCK WALL
was entrained in the hole? Note how in a pot magnet the outer cylinder wall is clear of the magnet.
So the hole may be too tight at one inch... try it, I liked the hybrid two core coil better...

In other words... if you put the magnet in a cup or pot and sank that down flush with the rotor face...
the rotor face could be all south with only the north poles of the magnets showing.. so the coil core would see the north pole but the coil would be interacting already with the south pole of the rotor
