PhysicsProf Steven E. Jones circuit shows 8x overunity ?

Thanks, Nerzh!  you've given a lot to "chew on".

Thanks also to Neptune for rechecking -- I was quite sure it was not Edison, and not surprised it was Tesla who made the discovery.  Here's that web link you referred to, link that works -- yes, an interesting read --

@Jouleseeker. My mistake it was not Edison, it was Tesla. I can not find the article again. Regarding the web address I gave in my last post, let me try again.

Please note that this is not a link as such, you will have to type it in yourself. I dont know how to create a link . If someone finds it, please create a link. Trust me, this is a must read article for those wishing to build a homopolar generator.

Hi all
As I am also interested in the subject, here my tiny contribution
I apologize if its off topic.
cheers

So it appears that the main advantage of the homopolar generator is the lack of back drag under load. There is not a lot of literature on the internet on the subject apart from the standard faraday disc experiment. But some very interesting stuff emerges if you dig deep enough. It would seem that some very powerful generators have been successfully built for high current purposes, such as rail guns etc. With modern high efficiency DC DC converters, we only need to get the voltage up to a figure between 2 and 12 volts, the higher the better. 
    With the high current produced, it would be good to produce a brushless design. However, I understand that for the machine to work , there has to be relative movement between the disc and the external circuit.So suppose we have a disc machine that will produce 3 volts. We can not just solder a LED or LEDS between the centre of the disc and its circumference, because there will be no light. No relative movement.
    Magluvins ideas look very promising. We need to investigate this because it is the only proven way to generate electricity without back drag.

Hi OU_Dot_Com persons,

While we are at documentation, should I suggest:

Here in the pic below, is my vision of what would be needed for a module. Lol, When I was naming the picture, I just banged it out. Polar Glider. What eva. ;]

The plate on the right is away from the unit to view the chewy chocolate center.

The grey material(magnetic core) is to give the magnetic field of the like poles of the mag samich a path to go other than out/in around ALL of the edges of the samich. You do know Im saying samich just to add comedy. ;]

I came up with this because I think the coils wound around that edge will have a counter affect on current in the coil. Maybe not equal or more than the wires that run along the large faces of the mags, but Im just anticipating anything, and I think Im right.

So the grey is the path or guide for the norths and souths of the magnets to try and limit the density at the coil wound edge and guide it as you see. Most of the blue N will take the grey path before expanding out of the wire wound edges. It should help a lot.

If I didnt think about this, I might have put it together without the paths and maybe gotten no output. Then what. So This is what Ive come up with so far.  And it will also help to concentrate the fields in the gap where the windings are on the larger surfaces of the mags. Like in a speaker, the way the iron core guides the magnets poles to meet on each side of the voice coil. Very concentrated.

This version shown should generate by moving it upwards or down in the position it is in. So just orient it for that motion direction, left or right, on a wheel, etc. 

My first test will be quite simple, not exactly as in the example pic. Im using laminates from ta transformer core, the straight pieces. They bend nice also. Im using just a few for the initial test so as to have more fresh ones for a more developed version after.

Ill try it on my bike wheel while it is upside down with a counter weight to balance it a bit.

I feel that on the outer rim of a 26in rim will provide good travel distance in time, speed, compared to a pulse motor wheel. If we want to operate at lower speeds, we will need a big basket of samiches all in series/parallel. Polar Glide stacks. lol  am I nuts er what. 

Gitter dun!   http://www.youtube.com/watch?v=OtAUsVXB9OU   ;]
