Bruce's Discovery, Tesla's Missing Link for his Unipolar Generator!

[mscoffman]

However, when I switched the magnet polarity, then the output amps became zero, which seems to indicate, that the spiral pattern indeed is capable of increasing or decreasing the output.

Yes the electrons are spiraling in the metal disk. So cut a physical spiral slot in the disk and it either directs the
electrons along the spirals or opposes them. (This may be how Tesla got the idea for his "linear pressure check valve".)
If parameters are not correct, one gets eddy current spirals as the electrons never reach physical edge of the disk
and contact point.

I suspect that the parameters that govern the spiral, are the momentum of the electrons, and a very strange average physical
velocity of actual electrons in the metal. We are used to dealing with the velocity of the signal propagation wave front at nearly the speed
of light but physical speed of electrons in metal is only about the speed of sound. I bet the form of the equation for the spiral motion
varies quite a bit from a clean cut pure electrodynamics equation, and the difference may be what causes physicists to treat the
homopolar generator as sort of a strange beast.

Bruce   ...   I think you are correct about the self-running part. I've known about Tesla's Unipolar Dynamo for at least ten years. I think I have a memory from the 1950's, not completely sure since I was a child. I was with my father in his business shop. If I'm correct, he was ordered to remove a welder. The mechanic complained, saying "it moves by itself". I'm guessing the welder was Tesla's Unipolar design, and they were confiscated in the whole country.
Regardless, from Tesla's Notes, I figured out, years ago, that the disk should be a pancake coil for maximum effect. Your idea, about using Tesla's bifilar coil, may be counterproductive. Have you tried it yet? From the Prof's paper, on the bifilar coil, it only works at certain frequencies, with 11 KHz being the best, if I remember correctly.

Here is my conclusion about the whole HPG topic.


The smaller, the less efficient, where only a gigantic model would reach an interesting performence, since, as it was said several times, with the diameter the output increases exponentially (^2).


I can hardly believe those who say they reached 70% efficience, or even more.


In a model that fits in a lab, the ratio between output as a generator and input as a motor is usually stupidly huge, read inefficient.


In my 2 microwave oven ring magnet sandwich HPG I reached silly 3 millivolt at 0.3 microamp, although only spun at probably 200 rpm.


I used a 1mm copper disc containing 4 spiral segmentations, with a closed ring in the center and at the rim, as suggested by tesla.


However, when I switched the magnet polarity, then the output amps became zero, which seems to indicate, that the spiral pattern indeed is capable of increasing or decreasing the output.

The bifilar was intended to replace cumbersome capacitors as stated in teslas patent. However were did tesla write about rotating copper plates to interrupt magnetism into the coil?

Perhaps faraday used similar methods.
