Homopolar Generators (N-Machine) by Bruce de Palma

[BinaryMan]

I found the idea of a conductive magnet rotating in its own field interesting. It's probably the simplest setup to make for testing ideas.

It would seem the key here is making a device where the physical friction of the contacts and resistance of the circuit are low, but more importantly, finding some way of drawing current from the device without experiencing a counterforce. As far as I can tell, drawing current radially will result in a force against the existing rotation. One alternative is to draw the current in a circular fashion (like a flat coil) to avoid this effect, but I am told that this will cause a field that couples with the external field reducing its effects on the rotor. In other words, the counterforce works to nullify either the rotation of the disk or the external magnetic field, both of which are factors in generating the voltage.

What we need is a novel geometry for the current flow such that it does not act against the forces which are creating the voltage. I am guessing at what might work. Let's take a case where the natual current flow direction is from the inside of the disk to the outside; we would need to force the current to go in the opposite direction as well near the surface of the disk to negate the side effects of that flow which is necessary for the circuit.

The first picture is the traditional path, while the second picture is an idea for doing this; dotted lines are pathways that are in rotation, while solid lines are the external circuit wiring. Some form of contact like a brush is implied where solid and dotted lines intersect. The yellow pathway represents an insulated wire that is connected to the rim of the disk, glued to the surface of the disk as it travels toward the center, then follows the shaft until it connects with the external circuit. The rest of the path is as normal. Somehow, I suspect this setup could have problems with the resulting flux pattern or the fact that both paths on the disc want to flow toward the rim of the disk.

A more creative solution is found in the third picture. The path of the wiring runs through a field that's far enough away that it doesn't interfere with the first one, and is of an opposite orientation (not necessarily shown properly). The second disk is just a platform for the wires. I tried all the combinations I could think of but a current flow that goes with the natural flow is always going to push back on the rotation, unless somehow it can be redirected into internal mechanical force that doesn't affect the rotation. However, we need to have some design where the current flow on the second disk counters the force of the first disk. You can see where I'm going with this ...

If using a coil type path, a bifilar counterwound coil path should have a neutral field so that's a starting point for that path design, but it's a lot more complicated I think.

Reed did it.   Conductive belt runs with zero contact velocity and electrically links discs (drum at perimeter).

Take power offa shafts.

Turtle, looking into this

Few posts back, I mentioned attempting to contact stardrivedevice

“http://www.stardrivedevice.com/over-unity.html
I’ve attempted to contact them numerous times, as they indicated on their site that they would be posting results out soon after the build, but they have not replied.
The build had started back a couple of years, but no results yet.”

Still no response from them, however;

The following appears to be the first real measured overunity backed by controlled experiment, data collection and analysis:

HOMOPOLAR "FREE-ENERGY" GENERATOR TEST
by  Robert Kincheloe
Professor of Electrical Engineering (Emeritus), Stanford University
Paper presented at the 1986 meeting of the Society for Scientific Exploration (San Francisco, June 21, 1986) Revised February 1, 1987

...
Conclusions
We are therefore faced with the apparent result that the output power obtained when the generator magnet is energized greatly exceeds the increase in drive power over that needed to supply losses with the magnet not energized. This is certainly anomalous in terms of convential theory. Possible explanations?

1. There could be a large error in the measurements resulting from some factor such as noise which caused the digital meters to read incorrectly or grossly inaccurate current shunt resistances.
If the measured results had shown that the computed generated output power exceeded the input drive power by only a few percent this explanation would be reasonable and would suggest that more careful calibration and measurements might show that the results described above were due to measurement error.
With the data showing such a large ratio of generated power to input power increase, however, in my opinion this explanation  of the results seems unlikely.
(A later test showed that the digital meters are insensitive to a large AC ripple superimposed on the measured DC,  but within their rated accuracy of 0.1% give a true average value).
2. There could be a large difference between the measured voltage at the metering brushes and the actual generated voltage in   the output brush circuit due to armature reaction, differences in  the external metering and output circuit geometry, or other unexplained causes.
As discussed above the various data do not seem to support this possibility.
3. DePalma may have been right in that there is indeed a situation here whereby energy is being obtained from a previously unknown and unexplained source.
This is a conclusion that most scientists and engineers would reject out of hand as being a violation of accepted laws of physics, and if true has incredible implications.
4. Perhaps other possibilities will occur to the reader.
The data obtained so far seems to have shown that while DePalma's numbers were high, his basic premise has not been disproved. While the Sunburst generator does not produce useful output power because of the internal losses inherent in the  design, a number of techniques could be used to reduce the friction losses, increase the total generated voltage and the   fraction of generated power delivered to an external load.
DePalma's claim of  free energy generation could perhaps then be examined.
I should mention, however, that the obvious application of using the output of a "free-energy" generator to provide its own motive power, and thus truly produce a source of free energy, has occurred to a number of people and several such machines have been built.
At least one of these known to me [13], using what seemed to be a good design techniques, was unsuccessful.

The setups and experimentations seem pretty thorough.
I’ve also tried to look up Emeritus Professor of Electrical Engineering. Robert Kincheloe
The closest and apparently credible reference is from
http://www.stanford.edu/dept/registrar/bulletin_past/bulletin01-02/pdf/ElectrEng.pdf
“Emeriti: (Professors)… William R. Kincheloe…

This may very well be the real deal, in terms of proving excess energy in principle, however, the practicality of overcoming friction and other losses appears to be difficult to achieve.

If anyone has additional info or has done research and/or experimentation with measured results and error analysis it would be appreciated if you post them.

Thanks

I'm focusing on a DC application where low voltage is not an issue- direct to  a parallel stack electrolyser.

The losses in conventional wind turbine setups are over 70%, what with the Betz limit, genny losses, rectifier losses, etc.

If this one-pole disc gen can be made to work, that has some serious ramifications for wind-to-hydrogen setups.  A VAWT has not the contact issues of a regular tracking horizontal wind turbine; hence, the hi amps are not an issue.

Just use big cables down the mast.

Thanks for that post, Mike

Turtle, still at it

No prbb keithturte.
It would be interesting to see if anyone else has repeated/confirmed
Robert Kincheloe's verification experiment.
this link maybe easier to read, graphs and test results also included.
