Latest: No back torque generator.

@yucca,

I do believe the homopolar generator (preferably in a unipolar configuration) can be overunity and produce excess electricity, in fact I have patented what I believe to be the only practical way to do so.

Yes, No. 5,451,825 I think. A most interesting design but I
cannot figure it out. Maybe you would give us a few words
about it.

Paul-R,
Yep, that's my 1995 patent.  The idea (way back then) was to circulate the current through a series of discs in 2 opposing magnetic fields.  I constructed a limited portion of the machine which had 2 opposing fields, and only 2 conductive discs buried in them.  In the construct, there was a conductive disc sandwiched between magnetic sheets  on each side of a steel disc.  The 2 opposing fields are then attracted to a steel disc in the middle and one disc has an outward radial current then the current goes through pins around the circumference to the other disc where it has an inward radial current.  The desired advantage was to eliminate the circumferential brush, but there were 2 big problems that arose.   First, my field strength was much lower than anticipated due to the flatness of the source magnet sheets.  Second and more importantly, I found that the 2 axial fields become one radial field coming out the circumference of the central steel disc.  This field produces a counterproductive voltage across the connective pins that eliminated 80% of the voltage of the entire machine.  So then I reassembled the machine with mu metal field shielding that were rated at 2 times the radial field.  The shields worked excellent outside the machine but when inserted in the machine they completely failed.  So then I inserted shields rated at 20 times the radial field and they completely failed too.  Thats about when I gave up on that design.  The major things I learned from that design were
1. How to construct effective and strong conglomerate fields. 
2.  That the unipolar generator exists in both a disk design (axial B field) and a drum design (radial B field). 
3.  That it is impossible to shield against the field in any way in that rotating frame which leads to parallels/explanations of the origins of the gravitational field. 
4. That a circumferential brush system is mandatory for success. 
5.  That magnetic fields must have a good return path or they diminish to zero. 
6.  That it is best to have a single field for unipolar success, and that current flow is directed to the central ring of that toriodal magnetic field during rotation. 
7.  That you only get somewhere in life when you have good money to spend, and when that money dries up, you'll be on your own.
I posted a photo of that tested prototype earlier in this blog, and I have 3 videos of it from '93 but they are in quicktime format and cannot be uploaded here.

This is what I propose at this time using no brushes.

1)  Two Halbach Arrays glued together with the same field facing outwards on both sides.

2)  A flat or pancake coil on each side rotating with the Halbach Arrays that would be electrically connected. One end of the pancake will be connected to the axis and the other end to the rim on both sides of the Array. The two wires on the rim would be connected together, while the two wires on the axis would lead to separate swivel bearings ( the wire on the right axis would go to one swivel bearing while the wire on the left axis would connect to another separate swivel bearing with a load connected to both swivels to form a closed circuit).

A current will flow from the right side axis through the pancake coil to the rim (This current may oppose the magnetic field on the right side).  From the rim it will flow to the axis on the left side (This same current may strengthen the magnetic field on the left side, thus canceling the opposition to the magnetic field on the right side).  From the axis, the current will flow through the swivel bearing which is connected to a load.  From the load, the current returns to the other swivel bearing which is connected to the axis on the right side to form a closed circuit.

The flat or pancake coils should provide a uniform saturated current just like the segmented wires.  We don\'t need to worry about connecting the segmented wires in series either.

It probably won\'t work because it is \"too good to be true\".  I have eliminated everything that could be a hindrance and may have eliminated it\'s abilities to even rotate.  This is engineering at it\'s best (or not....LOL).

Please don\'t laugh if this concept is totally wrong.  I am trying my best here. 

I will upload a short video on what I am referring to as a \"swivel bearing\" if your not sure what I mean.

Gravityblock,

I think your idea is sincere and interesting.
My belief is that it will succeed or fail based on what happens around the circumference.  The flat coils (you mean spiral right?) will produce radial magnetic fields when current flows.  I think you should give some thought to this radial secondary field; consider that the direction of wrap and rotation of each spiral will determine which direction this radial field will go, and it would probably be best if the construction is arranged so that those fields tend to cancel each other under load.  Since the voltage is a product of the radius, a spiral there will not raise the voltage over a solid disk, but it will change the shape of the secondary field.
  Also, remember the primary field has to have a return path.  With the Halbach array it will cause a highly non-uniform field around the circumference.  I see that you could bias this field to the point where half the circumference will have a rather strong field and half the circumference will have almost no field protruding, but you can't avoid having field there somewhere.  When rotated, the assembly will act like a magnetic pulsar around the circumference.  I can not predict the results of that, but it may not generate a voltage on the ends; I just don't know.  You might want to try the Halback array with solid discs before adding the spirals.

@GravityBlock,

Nice idea, if that design works then brush problems are no more.

Has anyone succeeded in getting a disk to show +ve on the circumference and -ve on the axle? As far as I've seen the electrons always migrate outward in all field and rotor configs and so the circumference is always -ve.
