Time to flare up this topic and enlist the global community to help further my experiments by open sourcing them, as we need a Over Unity Device made available on ebay to shut up the nay sayers and force industry and science to move on to the next chapter in the pages and annals of history and civilization.

I became aware of the homo-polar generator about 2001.  By 2004 I had researched, postulated, then constructed coarse experiments to verify my insights into the homo-polar generator.  Based on the results further experiments into the marketable design of a functioning overunity homopolar generator have been postulated and experimented with by me and a couple colleagues. The results are promising.

Now, I am not here to sell snake oil, I am here to see progress! The economics of life have dampened the research and development progress of my experiments. I therefore enlist the thinkers and tinkerers around the globe to peruse third party verification, and to a much greater extent to fire up thier own small shops and to manufacture and flood the online markets with functioning devices.

I will no longer hold my cards close to the vest, protecting any intellectual rights or ego of discovery. I would rather be able to just buy one at wallmart so here goes.....

My next post will include what I have on hand to offer in the spirit of open source, that we may all participate in our open source future civilization.  Because eventually we must leave this solar system or become extinct, so no time like the present to start....

Homopolar Stack (multiple generators on one common shaft) Brent Hasty
« Reply #1 on: September 05, 2010, 09:46:31 PM »
Now begins the GPL Open Source posting of the best information I have on hand from my research, theory, and experiments into building a marketable homopolar generator that will yield some level of easily measurable overunity output.

I will attach a couple blueprints that should make replicating simple. I only require (request) all resultant discoveries, and improvements built upon and in addition to, be likewise added to the public knowledge base in the spirit of GPL Open Source evolution. As the worlds need this day, yesterday and tomorrow are too great to worry about patent capitalization. If any have the the ability for minor or mass production, it is highly encouraged; I would smile to just see the market flooded by this or any other functional zero point energy generator.


The first key of the homopolar generator I found through experiments is:
      For the same Axial Magnetic Orientation the flow of DC Current Reverses with a reversal in the Direction of Rotation, clock wise + rim - axle --- counter clock wise - rim + axle.

Second key of the homopolar generator I found through experiments is:
       If two or more homopolar generators are placed on a non conductive common shaft and electrically wired in series, with their magnetic axises in opposition (that is north to north or south to south or N/S S/N N/S S/N etc....) The sum of the output voltage will be the additive of each of the individual homopolar generators on the common shaft. In this manner it would be possible to build a homopolar generator with a 14 VDC output that would feed a plethora of common off the shelf electric appliances, including a grid tie inverter, hence anything.

        I will coin a phrase to describe this as a Homopolar-Stack

Third key of the homopolar generator I found through experiments is:
       When placing a even number of opposing homopolar generators on a non conductive common shaft, intelligent design can yield a center positive on one end and a center negative on the other end of the shaft. This will allow for the elimination of the rim or peripheral pickup brush and an enormous amount of drag, by allowing stationery pickup brush to be located in the center point of rotation with the least Feet Per Minuit of rotary contact.

Forth key of the homopolar generator I found through experiments is:
        Two or more independent homopolar-stacks can be wired in series or parallel to multiply the power as needed.

Fifth key of the homopolar generator I found through experiments is:
        Multiple spiral slots cut in the copper discs by laser/plasma can induce a complementary electromagnetic field to that of the permanent magnet during discharge of the homopolar stack, further increasing output when oriented intelligently to the magnetic axis and direction or rotation of each of the stacks sub homopolar generators.

Sixth key of the homopolar generator I found through experiments is:
        Support it on a magnetic bearing in an evacuated bottle to reduce parasitic losses.

Seventh key of the homopolar generator I found through experiments is:
         In a homopolar stack to maximize output and minimize eddy currents it is important to circumferentially provide a complete conduction path from one generator to the other on the periphery and near the center point around the axle.

Yet to determine:
First:
      what effect does the opposing spacing of the homopolar stack have on output.
              example      -n/s-----------s/n-   or -n/s--s/n-
      If greater spacing improves output then
              what is the effect of a diamagnetic material (such as bismuth or Bucky ball carbon) separating the individual homopolar generators on a homopolar stack?

Build one for yourself, build them for your neighbors, ant there neighbors....

Hi teknomage,
thanks for sharing your experiments. This is very interesting.
Could you give us an idea of the dimensions of the pictured stack ?
Have you really been doing the experiments at VHRPMs of 20K-50K , or at slower (more reasonable & less scary) speeds ? :D
I also wonder about the behavior of mercury contacts at those speeds...

I will have to review the theory on the homopolar generator before continuing, to understand fully the principle.
Keep adding to this thread, please.
P.S.  Maybe hypercom should repost his message here, for completeness. He too is onto something big.

Brent,

I noticed on your drawing it says patent pending.  I have released many drawings on this forum, using N/N or S/S configurations to increase the voltage and to extract the current from both sides of the axis.  This is nothing new.  In fact, I have hammered this idea on this forum over the last few years.  You could even go brushless by using multiple halbach arrays with this concept.  I don't know why I'm telling you this, for you will probably try to patent the brushless concept also.

This was designed around 3.5x.5" neodymium ring magnets, to be fitted inside 4" PVC tube where it could be sealed and evacuated.

The current rendition of the brush mechanism is having the + and the - ends of the rotor shaft slightly concave followed by a 1" diameter brass ball then another concave cap that is lightly spring loaded. Forming a contact from rotor to stationery housing whose point of contact is self centered in the axis of rotation. Looking something like    (0)

Yes, experiments to date have been at lower rpms in the 4 digit range, most research has been in the direction of making a device of useful voltage having reduced drag with a lesser focus on amperage. As speeds have gone up we have had some success taming vibration by machining a groove on each end of the rotor rim and encapsulating some free moving ceramic balls to act as a self balancing mechanism. 

In the evacuated chamber we have introduced a rarefied amount of argon, whose molecules are centrifugally compressed by the rotor to the housings cylinder wall. In the wall is a pathway to allow the molecules to escape in a loop where they are reintroduced to the chamber about the brass ball in the zone of lowest pressure. They are then drawn into a hollow rotor shaft through ports in the concave cap. The hollow rotor shaft has along its length holes to allow the molecules to exit into the spiral slots in the copper disks. From there they are flung out of the rotor and compressed against the housing wall..... The loop repeats.

The rarefied argon serves to aid the rotor in heat removal for sustained higher power draws.

In future iterations we believe the brass ball can be removed and the rotor free floated on a halbach array with only a spark gap between the rotor and the housing. The focused molecules of argon spiraling into the shaft would then be excited with a high voltage/frequency start circuit to arc the spark gap and initiate a plasma state contact to the rotor to draw power.

The patent pending is a note on this lab drawing similar to the January 1st 2005 note of when I sketched it. Since development progress has been slow over the last 5+ years, I posted the lab drawings here to GPL Open Source them and encourage further development beyond the lab to manufacturing and marketing.

How is it a halbach array would allow you to go brush-less?

Without contact, how do your propose inducting DC potential off the rotor?

Thanks Brent.
As the basic N-machine is a low-voltage/hi-current device, how successful has been your stacked arrangement, to increase the voltage ?
Is the voltage increase proportional to the number of magnets ? (or pairs).
The balancing issues must be the greatest problem to overcome in this type of machine. A dynamic balancer would be a mandatory piece of equipment to have...
The supporting shaft must be non-conductive, but at the same time as ridgid as possible. What material have you been using ?  Would it be possible to use a large steel tube for support, surrounded by another insulated tube ?

Have you tested it with un-evacuated chamber, with just air inside ? I suppose that the drag was quite high.  But at higher speeds, the centrifugal force would probably "evacuate" the inner spaces between the plates and magnets, which would slightly pressurize the peripheral area. Then you could let the casing open to athmospheric pressure and the inside pressure would equalize with the outside. For cooling, a restricted passage in the shaft would let air in. Air might be more effective for cooling than argon, but I don't really know. Of course, for the spark gap, it's not ideal.

How much power have you been able to extract to date with this 4" generator?
Sorry for all those questions  :D

How is it a halbach array would allow you to go brush-less?  In the same way the halbach arrays allow you to go brushless in regular induction motors.

Without contact, how do your propose inducting DC potential off the rotor?  By using what I call "virtual relative motion" between the discs.  In this setup there will be two discs and a closing circuit.  One disc will be induced with a negative polarity while the other disc will be induced with a positive polarity.  Basically, the two halbach arrays will be enshrouded in copper, and will rotate inside this copper shell.

I do realize you will say there must be relative motion between the disc and external circuit, but I will argue the relative motion only allows the disc and external circuit to have equal and opposite EMF that does not cancel each other out.  For instance, in this configuration disc/N/S/disc, the left disc will have the same polarity has the right disc if everything is rotating together, thus there is no potential difference in this setup.  In a configuration like, disc/S/S/disc, then the left disc will have an opposite polarity as the right disc, and there is a potential difference between them.

I also realize you will say, rotating the magnet does not induce an EMF when the disc and external circuit are stationary.  This is true, but remember we are dealing with two halbach arrays.  Rotating a PM on it's magnetic axis above a stationary PM, will not cause the stationary magnet to rotate, but rotating a halbach array above another stationary array will cause it to rotate.  I hope you see the difference with this.

I also realize you will say, the magnetic field of a halbach array is not uniform like a PM rotating on it's magnetic axis.  I will argue a halbach array can be built to have a uniform field.

@Hypercom

Interesting reading, seems to explain the HPG very well. I need to read it again and try to understand more on the concept of the spiral, and the exact effect it generates and why the author thought it was important.

Regular induction motors are already brush less and have no need of a halbach array. Now I could understand if you said a halbach array can make a induction motor bearing less.

So what you are describing is using a halbach (one or two?) copper shrouded on the rotor? and one in the housing underneath stationery copper that is allowed to rotate in sync with the rotor?

Would not the EMF in the copper enshrouding the halbach rotating relative to the copper subject your device to lorentz slowing and dragging upon the rotor?

How is it a halbach array would allow you to go brush-less?  In the same way the halbach arrays allow you to go brushless in regular induction motors.

We have gone as far as 1 volt using 4 of these small magnets rotating at about 6000 rpm, we were in the process of determining the effect of the spacing of the generators and the the effect of placing permeable and diamagnetic materials into that space. Until I got laid off from my job.....

If and when I can get around to the last few details of optimizing for voltage, then it is just a matter of building a homopolar stack of enough nodes to reach the target output voltage.

Yes we found the voltage linearly proportional. RPM's always help ;-)

For the shaft we were using a machinable nylon rod of a diameter that closely fit the ID of the ring magnets.

Rather than an insulated steel shaft, once a finalized version is defined I would use a unidirectional carbon fiber rod, if its conductivity proved troublesome despite its very high resistance it could be wrapped in fiberglass.

We went with the argon, due to its high atomic number and ability to carry current in the plasma sate without reacting since it is noble. Heading in the direction of a free floating evacuated magnetically suspended rotor with no hard physical contact. The use of a high voltage/frequency start to arc a lower voltage across a spark gap is similar to that used in arc welders. Tungsten faces with high surface area would be used across the spark gap to sustain the flow of electrons and survive it.

Like I said we were focusing on the homopolar stacks optimization for voltage when my funds ran low. We have not yet done the spacing and substrate testing in the stacks.

As the basic N-machine is a low-voltage/hi-current device, how successful has been your stacked arrangement, to increase the voltage ?
Is the voltage increase proportional to the number of magnets ? (or pairs).

Would not the EMF in the copper enshrouding the halbach rotating relative to the copper subject your device to lorentz slowing and dragging upon the rotor?

Any motor which uses a commutator or a slip ring has brushes. The commutators can be replaced with power semiconductors to reverse the current without the need for brushes.  Halbach arrays are used in AC brushless motors.

What I am describing is two circular halbach cylinders enshrouded in a copper shell.  The two cylinders will rotate together inside this stationary copper shell.  A closing circuit is required to avoid cancellation of the EMF.  The closing circuit will run from axis to axis on the copper shell.  Now, I don't expect you to believe this will work in a stationary frame, so I will show how this can be made brushless in a rotating frame where everything is rotating together.

Take two magnets and two discs and place them on an axle like this, ==D/S/N====N/S/D==.  Now electrically connect the rim of the left disc to the rim of the right disc.  Also electrically connect the axis of the left disc to the axis of the right disc.  Depending on the direction of rotation, the current will flow from the axis of the left disc to the rim of the left disc, then from the rim of the left disc to the rim of the right disc.  From the rim of the right disc to the axis of the right disc, then from the axis of the right disc back to the axis of the left disc using the closing circuit.  As you can see, without the closing circuit, the EMF would cancel each other out at the axis of one of the discs.  This doesn't do us much good, because we would need to be rotating with the system in order to extract the current for our use.  This rotating frame is a proof of concept for a brushless HPM/HPG, which should be applicable to a stationary frame in the right setup.

@Brent:

Are you familiar with the Paradox 2 experiment by Distinti?  If not, then here's a publication describing this experiment, http://www.distinti.com/docs/pdx/paradox2.pdf and a short video clip showing the device attached to an oscilloscope, http://www.distinti.com/docs/pdx/pdx2.MPG

Not anymore than if the disc rotated with the magnet and a stationary external circuit.  I suspect you think the counter torque is eliminated because the magnet and discs are attached to each other and rotate together?  Having the disc attached to the magnet and rotating in sync with each other does not eliminate the counter torque.
