Has anyone ever tried to replicate Bruce DePalma's N-Machine?

I am playing with this one right now. I'm using parts from an old VCR.
The read head is a very well balanced aluminum disk.
I was trying to find info on how to run a VCR read head without the other circuitry.
Anyone have info on how to do this?
I plan on turning the VCR head upside down and gluing a magnatron ring magnet to it. That should give me some power output.

This device is supposed to give off high current with very low voltage.
The first thought I get is the low voltage is somehow the resault of the short
distance from the center to the outside of the disk.
Increasing this distance increases voltage. If that is the case, then this disk
has the characteristics of a transformer winding.
That being the case how could we increase this distance to get more voltage without using a larger diameter disk.
Perhaps some form of windings could do this.
I liked the statement I read, that the reason a generator causes drag the more current you draw from it is,
because it is functioning as a motor at the same time as a generator.
Now there is food for thought.
It explains how these pulse motors, can be designed to charge there own batteries.
But what is even more interesting to me is that the magnet can be mounted to the disk and still produce power.
What if you mount the stator magnet to the rotor windings of a generator.
Has anyone tried this? If a disk works like this why not all generators?

More input on this would be awsome, any other theories, or ideas?
I had one: Tesla used spiral windings in his own patented verson of a transformer.
He wound 2 wires in parallel with each other, together in a spiral on the same core.
Then he connected the end of one wire to the begining of the other.
Now he used a spiral.
What if we put a spiral winding inside an insulated disk, and then mounted ring magnets on each side of it.
Example: Use 2 old CD's with a coil sandwiched between them, and sandwich them between 2 ring magnets.
One end of the coil sticks out the center, the other end could be wrapped around the outside to form the outer conductor ring.
And there you have the equivalence of a much larger disk without the larger size.
Then we just spin this assembly as a large flywheel. Vuala! You have high current, and higher voltage output.
Somehow this should work. Unless I have the concept all wrong?

In any case this is one experiment that's in most peoples grasp.
(Old CD's, Old Magnetron magnets, Old VCR motor, wire spiral, glue gun, epoxy,Train transformer,Bridge Rectifier)
Any good ideas on how to fill the center hole of the CD's to mount them on a motor?
Some older VCR's use a regular, high quality motor to run the capstan.
That's the rubber pinch roller that the tape moves through.
These motors are farely large and can be controlled well with a varable DC power supply.
Just turn up the voltage slowly and watch the speed increase. Over 6000 rpms should be a breeze for these motors.
Graphite brushes will work. but the best would be brushes made of a liquid gallium alloy.
The only tricky part, I see is balancing the flywheel for smooth rotation at high speed.
How do they do that? I always wondered how they know were to drill those holes for balancing flywheels.
If you know how to do that then adding and removing glue gun glue could balance things out.

The answer to free energy is out there, we just need to find it.
Till later happy experimenting, Harold.

either let the disk spin hanging on a string from the motor, then it will self-balance.

Or use the professional method for balancing axles: Put two metal shims with a large diameter (like CDs, for example) on an axle as far apart as your to-be-balanced-axle requires. The shims must be balanced themselves. Put their axle onto needle bearings or thin roller bearings. Now double this setup and set the carrying axles as close together as their size allows.

This setup may look a little similar as a support for sawing wood, where on top you would put the stem to be cut. Only her you put the axle to be balanced on top of the four metal wheels, which have very low friction "to ground" and also "to the to be balanced axle".

If you take plastic wheels instead of metal, the friction may already be too high.

A third method for balancing is to spin your to belanced setup and by trial and error adjust some balance weights until the rotation is vibration free.

good luck!
