Homopolar Generators (N-Machine) by Bruce de Palma

[broli]

ETA: Tom Valone did a very interesting experiment that he talks about in the Homopolar Handbook. He actually mounted a simple LED voltmeter arrangement directly to the disk of a homopolar dynamo, connected at the center and the edge. He found that when the voltmeter rotated along with the disk, he could detect no voltage generated. But when the voltmeter was stationary in the laboratory reference frame, connected by the usual radial and axial brushes, he did detect voltage from the rotating dynamo.

This is kind of a flawed experiment, a volt meter is not the correct device to measure the electric field in the rotating frame. A voltmeter needs a closed loop circuit to do its thing. Rotating an entire closed looped circuit elliminates any induced voltage ergo the experiment proves that a voltage cannot be generated when the entire circuit is rotated.

A corrected experiment would use a sensitive electrostatic probe rather than a run of the mill volt meter. The reason is that when the disc is rotated the voltage induced will push charge to the rimm/center which causes a measurable electrostatic field in the vicinity. However commercial electrostatic probes are not meant to measure mV to 1V fields. Perhaps there's an IC circuit out there that does?

Hi

I watched the following educational video (from 3:55) and I thought this design MIGHT help to increase the output power of N machine. As you know the length of wire determines the voltage output and I believe the girth of wire will determine the current output. I think the reason for N machine to have high current and low voltage is a short distance between the rotor and edge of the copper disk and high current is cause by the thickness of the disk. The rotation cases the electrons to move from the center of the disk towards the edge (according to Fleming's left hand law). So I decided to use a solenoid, locate two magnets on one of the edges of the solenoid and rotate the solenoid around its Y axis. The same Fleming's left had law will push the electrons from the left hand corner of solenoid towards the right hand side and that is exactly what we need: Movement of electron in a long and thick copper wire. Please let me know what you think

Just to make it clear, I mean the magnets are going to be attached to the solenoid and solenoid is attached to the shaft of motor and solenoid, shaft and magnets all spin at the same time!

No one wanna tell me "its not going to work"? I'm really disappointed. Not even MileHigh? Come on guys, tell me its not going to work, Otherwise I might think OU is possible

Good Morning Sam!
I've been thinking about that since I tried my first replication. As you said, if we can make the distance between the center until the edge of the disk "longer", probably we can get the voltage higher. I'm in the middle of other project, but I'm planing to build a device to test this thesis.

Hi Ariovaldo
Thanks for replying my friend. Good luck with the project that you are working on. I find N machine a very interesting setup and I hope we can make something out of it

Best Regards
