Homopolar Generators (N-Machine) by Bruce de Palma

The US Navy is using them in its
new class of warship:

Very good Liberty!. This topic has needing a revival.
The Faraday Disk (the primitive version of generator homopolar) was the first electric generador being replaced by the alternating current system we use today invented by Nikola Tesla. Paradoxally also Nikola Tesla was the first to say that back-torque may be artfully reduced to much less than a classically-figured level on a Faraday Disk machine. Here the document written by Tesla: http://www.stardrivedevice.com/Tesla_notes.html
It is interesting that still today the physics are looking for a satisfactory explanation, as this very good paper from the University of Maryland that strongly suggests the real explanation may lie within the purview of Special Relativity: http://www.physics.umd.edu/lecdem/outreach/QOTW/arch11/q218unipolar.pdf

What think you about this experiment?

One resistive load connected to disk and rotating together.
Note that no brushes are required and no relative movement between electric parts.
The temperature of the resistance might be measured by Thermography. (http://en.wikipedia.org/wiki/Thermography)

I can't find a similar experiment on Internet.

Hi Penguin Hood,

By the way, the penguin picture is very original, I like it. 

To answer your question, I think that relative motion from the point of power draw to the magnetic field is necessary in order to cause electron flow from a Faraday disk (homopolar generator).  My guess is that no power would flow to the resistive load spinning with the generator.

I am working on designing a way to make a homopolar generator produce a much higher voltage output (making it much more useable) while maintaining high current from one device.  It is untested, but I think that it will work, (at least it works in my head at this point).

Thanks Liberty for give your viewpoint.
Unlike all other dynamos, the homopolar generador cannot be analysed using Faraday's own law of electromagnetic induction because the magnetic field is stacionary. Moreover, the circuit in the Faraday disc is parallel to the magnetic flux vector and therefore encloses no magnetic flux.
Instead, the Lorentz force law is used to explain the machine's behaviour. This law states that the force on an electron is proportional to the cross product of its velocity and the magnetic flux vector. Which prompts the question, "velocity relative to what?". Seems that the correct interpretation of the velocity of the electron is that it is relative to the static parts of the machine, which are the sliding contacts and the circuit to which they are connected... as you said before.

Penguin Hood... another Tesla fan

I would say to an enterprising man....Read the works of Edward Leedskalnin...then go and read that Tesla article on Faraday discs....
There is no such thing as electricity.....it is magnets.
I tell you the truth....there is a whole new theory in the above mentioned works....and it has nothing to do with electrons.
To make magnetic currents from a single wire, the wire must be placed so that the magnets are going from the center to the outside or ends of the wire...and both north and south pole individual magnets....they are so small...they can pass through anything.
When they run side by side in the same direction, they are not attracted to each other.
The magnets can only run against each other!!!!  Contradiction....i think not.
When a large solid mass is put in an induction furnace, it is easier to melt than many small iron flakes....When the iron flakes are in the furnace then they throw out magnetism at their edges and it is wasted, so they melt at the bottom and can easily form a crust on top of the furnace. If a crust is formed then the center will begin to superheat. At this point the crust must be fractured to vent the gasses formed underneath.....so you see that our Earth is the same...or the Earth is subject to the same forces as an electric induction furnace.....that's why we need volcanoe's....
Since the Earth has many types of matter, it has a large crust....but it still needs venting....
In the southern hemisphere the N pole magnets are going up, and the S pole magnets are going down...In the northern hemisphere it is the opposite......
The magnets are the base of everything.
Lenz's law is incomplete in its descriptons.
The works first mentioned will refine it.

scotty1, could you please elaborate on your description above regarding the magnets and the wire? Is there a simple experiment one can do to see what it is you are saying? Sounds very interesting, and I would like to understand it completely.
