Acoustomagnetic TPU / SEG calculation model

@Mark,

As you know, also free radicals can be used as material that has a unpaired electron.
For example polyacetylene black melanin has a unpaired electron.

" melanin is the best sound-absorbing material known[22] due to strong electron-phonon coupling."

Sorry to interrupt guys -

I've been searching my system to find a link I had previously - all to no avail.   
(Probably) around 2 years ago, there was a video from an older guy (American I think) who had a (form of) gravity engine.
From memory he had a working version in his shed, which turned very slowly (maybe 30-40Hz).
Then the video went on to show it in his pickup (moving slowly over a length).
(Possibly on Google Video).

AFTER this, he went on to give His Explanation of how Gravity worked.
It was all in relation to rotations etc, and his explanation was excellent.
I have a Vague feeling that you had to wait until approx 27 minutes into his video to get to this (I think it was 35-40 min long, but can't say with any certainty).

Does this ring a bell with anybody ?
Can anybody point me in the right direction. 
I believe I originally got the video link from these forums, and figure that one of you guys would probably know exactly what I'm after.
Can you help ?

Thanks,
Jeff.

Yes. He has long curly blonde hair and doesn't wear a shirt or it's open. But I can't remeber either what his specs are.

There is another another one: A guy is in a little white GM car. It is about the size of Ford Echo. The base is flat like a skateboard and the bodies are interchangable. All drive power are in this 6" thick platform. There are no foot pedals and all controls including the rearview camera are in the steering controller. The steering control slides left to right for driving in different countries This vehicle needs no charging and has no combustion properties in it. He is driving it on the top floor a parking garage type ediface. Youtube, Anybody?

I decided to build some core for testing purpose. I plan to use polyurethane foam for the core material, aluminium , ferrite, and nickel powder.

Can you recommend a ratio for the powders?

Should I use any special method to mix the powders, or can I reach enough homogeneity with using kitchen robot mixer, when the the monomers are still in fluid state?

The core magnetic saturation point is important here, use TPU phonon calculator to determine the needed magnetic field strenght ( typically around 0.22T ). Then mix nickel and ferrite powder with a amount that makes it possible to achieve this calculated magnetic field strenght. Aluminium powder works here as a paramagnetic material. Use ferrite with a permeability 2000.
Use 2-component polyurethane foam, mix powders with 1 component, then add  2:nd component.
First build a sample to determine the speed of sound in a composite material, then calculate the core dimensions with a TPU phonon calculator.
Place 1-turn wire loop in the middle of the core for HV input.
Black melanin is the best known acoustic wave absorber, because of strong electron-phonon coupling. If you have available this material, add this to composite.

To build up a vortex like vertical EM cylindrical wall, we need to rotate the transmitting place.
With a TPU this happens, when an acoustic wave travels around the cores circumference and wobbles free and unpaired electrons spin precession axis -acoustomagnetic resonance, that creates microwave emissions.

For example, if you use urethane composite core material, it can have a sound speed around 1800 m/s.
If you design a core, say 34 cm diameter, the sound wave rotates around the core at 101886 rpm speed. In this case, there are total 37 acoustic waves ( wavelenghts 2,9 cm ) travelling around the core. This leads to system, where the transmitting places rotates also. Tune applied vertical magnetic field so that Electron spin precession frequency has this same 2,9 cm wavelenght- around 7,7 Ghz in a 0,28 T applied  DC magnetic field .The created vertical direction and cylindrical shape microwave emission has this same 7,7 Ghz frequency.
