DEAR ALL,

PLEASE FIND ENCLOSED THE FINISHED TOROID GENERATOR SET-UP.

PRELIMINARY TESTING SUGGEST THAT THERE IS NO EFFECT ON THE PRIME MOVER WHEN THE GENERATOR COILS ARE LOADED - MEANING NO BACK EMF INDUCED FIELDS IN THE AIR GAP.

IN DEPTH TESTING RESUMES ON WEDNESDAY.

CHEERS
Thane

...I reviewed DePalma Homopolar/Unipolar generator research. ... My University and High School Physics text have no mention of the homopolar generator. Apparently because it went against Lenz's law and could not be explained by modern physics...

I think the reason you don't see it in textbooks is more straightforward than that. The reason is simply that it didn't work. OUman

How quaint that some people are so willing to publicly display their ignorance.

How completely unnecessary when there is so much information available. One could actually
read how the government seized his work? One could actually read the many cases where the government has confiscated an inventors ideas and forbidden further research. Do they do this for inventions that don't work? No. Is there an oil cartel? Yes.

How about Paramahamsa Tewari? His homopolar generator not work either?

HOW LONG BEFORE THIS SITE IS SHUT DOWN?
SHOULD WE START AN "OFICE" POOL?

@RCH

It's certain that the peer review process can be an untidy thing.  I dated an academic for a number of years and he settled more than one score, both real and imagined, through anonymous peer review.  He also used the process to jockey his own position. It was shocking and disenchanting.

The rotor will be driven with a 250W 12V DC motor with a direct coupling from above.

@Uli
I'm looking forward to your results.

@Thane
There's no doubt Thane that your particular coil arrangement is unique. I'm actually very intrigued, because your magnets within cups represent a semi-closed system within themselves, while your coil assembly is a closed system within itself, but an open ended system with respect to the magnets. As you are aware, I achieved very similar results to you with a completely open system.

One thing that appears to be common to both our systems is the actual air gap between the coil setup and the magnets. From my memory, I believe you found that a greater than usual air gap (but not too great) yielded a better result in your system?

Normal generators, as you would be aware have the minimum air gap possible. Usually around 0.5mm or less. My neo magnet alternator had a 3mm air gap, which is large by any conventional standards.

You seem to think that for this effect to work, there must be minimal flux in the air gap from the induced mmf of the coils ?

I know you've said that you don't like reading other peoples prior work, because it's a distraction to you, but I think you should read page 5 on my site very carefully. ( http://www.totallyamped.net/adams )

The small section dealing with the "transition wall", is relevant to the air gap, and hence your work.

It is not a minimum of induced flux in the air gap that is required, but a specific flux relationship between the magnets and the core, whereby each component is the magnetic equal of the other with respect to the air gap between them.

In this situation, in a sense, you are right about minimal flux, but, not because it is not there, but rather because the air gap becomes a null point or bloch wall between the magnet and the core, while the magnet and core both have individual bloch walls within them. One bloch wall being permanent (within the magnet) while the other is induced (in the core), and the bloch wall between them (in the transition wall zone) resulting by mutual induction from both the magnet and the core (when the coil is loaded).

If the air gap is too small, the overwhelming influence of the magnet will breach the transition wall and destroy the bloch wall within the core. There will be only one "shared" bloch wall, instead of one permanent, one induced, and one shared mutually induced bloch wall.

What is the  transition wall and why is it so important?

Here's a little extract below from Wikipedia that may help to put it in perpective.   
..........................
Far away from a magnet, the magnetic field created by that magnet is almost always described (to a good approximation) by a dipole field characterized by its total magnetic moment. This is true regardless of the shape of the magnet, so long as the magnetic moment is nonzero. One characteristic of a dipole field is that the strength of the field falls off inversely with the cube of the distance from the magnet's center.

Closer to the magnet, the magnetic field becomes more complicated, and more dependent on the detailed shape and magnetization of the magnet. Formally, the field can be expressed as a multipole expansion: A dipole field, plus a quadrupole field, plus an octupole field, etc.

At close range, many different fields are possible. For example, for a long, skinny bar magnet with its north pole at one end and south pole at the other, the magnetic field near either end falls off inversely with the square of the distance from that pole.
...........................

ref link here  :  http://en.wikipedia.org/wiki/Magnet#Calculating_the_magnetic_force

The transition wall represents an area of change in magnetic state, between a magnet and a paramagnetic substance. (in this case, a ferromagnetic core)

It is the area, where the attraction between the magnet and core changes from an inverse/distance squared relationship, to an inverse/distance cubed relationship.

It is an area where a quantum change occurs in the magnetic relationship of the magnet and core.

When the transition wall is breached, the magnet manifests a greater inductance into the core,(and hence a greater potential output) but also manifested is a much greater mutual drag between the magnet and core, and a greater reluctance within the magnet and core.
