Tesla's Unipolar Dynamo

 There are so many amazing energy inventions. The problem is they almost always require professional manufacturing which can't be done at home. So I prefer the simplest ones.

As has been shown here, about the Walter Russell coil generator, mankind moved away from the original correct design by Faraday. He had the correct perpendicular arrangements in his motor. Tesla followed Faraday's principles with his Unipolar Dynamo. And he made improvements. With it's very high current and low voltage, it was used for welding. That can be modified now, by rectifiers and a Cockcroft-Walton voltage multiplier, to get a house current. Voltage is also increased by using multiple disks separated by insulation layers. I'm not certain of this, but from something I think I heard in my father's business truck shop, when I was less than 10 years old, it's possible that those Unipolar welders continued to turn by themselves after they were started.

Here's how it would work. Tesla's Notes covered cutting the copper disk, between the electromagnets, into curved, spiral sections. The spiral curved paths, on the Unipolar Dynamo, are like a large electromagnet coil winding. They force the current, that runs through the disk, to produce a magnetic field. Curving the spirals in the right direction would reinforce the electromagnetic field acting on the disk. The stronger the current, the stronger the magnetic field would become, which increases the output.

My idea, to modernize it, is to use two neo cylinder magnets in parallel, one above the other, on two separate axes. The two magnets are arranged in opposite polarity. A carbon fiber belt, or other conducting belt, would wrap around the outside of both magnets to be the electric connection. The disk part would become a very heavy gauge pancake coil, attached to both ends of each magnet.

It may or may not be self-running. It doesn't matter if it's less than unity. Faraday's correct arrangement would make it far more efficient than modern generators that fight themselves.

This video shows that when a disk/ring magnet is centered below a spinning copper disk, the eddy currents (Lenz's Law) do not oppose/brake the copper disk. The double ring in the bottom of the cup holder is the magnet. The ring far above is to center the axel.

When the magnet is moved to the edge of the copper disk, the eddy current do slow the copper disk.

 

 

 

Another example. The spin of the magnet is not opposed. The force is perpendicular upward, levitating the magnet.

Lenz's Law doesn't apply to the unipolar arrangement. Lenz's Law opposes Faraday's Induction Law which requires a change in the magnetic field. There is no change in the magnetic field of a unipolar dynamo.

It's possible that the Lorentz Law could cause a counter reaction.

Hi idlea1man

If I can afford I found a little secret in the pancake coil,

try it with coaxial cable RG58 50 ohm impedance, besides being a perfect asymmetric capacitor it is more pancake even more powerful.

The other coaxial cables are more isolated at 2kv and more.

I haven't seen anyone try it, but it appears that a pancake coil, alone with no magnet, would generate the magnetic field needed to function as a Faraday Disc. The generator mode would require an external electric jump start, to begin generating.

When the setup is used as a generator, the Lorentz Force is causing the radial electric movement. It's interesting that Faraday induction is not working here because the magnetic field doesn't change. The Hall Effect may also play a part. With the Faraday Disk as a motor, the Lorentz Force evidently acts to cause the disk to spin.

I found an OverUnity Forum member Post about Tesla's Unipolar Dynamo, by Bruce_TPU. Is he reliable?

overunity.com/8934/bruces-discovery-teslas-missing-link-for-his-unipolar-generator/#.Wt4T-LCWy00

He hadn't done it yet, but officially claimed, in 2010, that using a bifilar pancake coil would negate Lenz's Law and allow the Dynamo to self run.

As often happens with me, I get a new idea about one subject when I'm looking at a completely different subject. I thought of a better design for a permanent magnet unipolar generator. Sorry I don't have a program to make an mage of this. These generators have been criticized because of physical problems at the output brushes. With 100's of amps, there can be burning overheating.

My new design is to place two cylinder magnets inside of a thick walled aluminum pipe, or other metal. The magnets have the same poles facing each other, at a comfortable distance. The cylinder magnets have a large center hole, fit with a thick metal bar protruding outside the ends of the pipe. These are two separate metal bars ending at the inner edges of the magnets, so there is no inner connection between them. The purpose of the thick pipe, and bars, is to carry the large current without overheating so much. Water cooling may be necessary. I mention aluminum for it's heat-sink, cooling property. An insulated motor turns the assembly.

The current travels from one outside bar, up through one magnet, across the metal pipe to the other magnet, down through the other magnet to its metal bar, and out that bar on the other end. Output current is drawn from thick contacts touching the ends of each outside bar.

My above post has been updated.

Also, Peter Barlow, in 1822, had the same motor/generator principle before Faraday. Below is Barlow's Wheel.

Other modern versions of Tesla's Unipolar Dynamo have been invented, under the name homopolar, by Bruce DePalma, Trombly/Kahn, and Tewari. They were heavy and required a substantial motor to turn the rotor. That was before the new lightweight Neo magnets that I would use. They still claimed +unity. At a loss to explain this, they started the terminology that the energy came from "space", space generators.

Below is DePalma's beautiful unit, which he called the N-machine, "N" meaning to the Nth degree, suggesting electricity comes from an unlimited energy field. He was making units in the 1970's. The armature is 800 lbs.

The beauty, of the Faraday motor/generator arrangement, is that electricity is allowed to take its natural path, in the disk, perpendicular to the magnetic field. It is not constrained within the path of a wire coil. The restriction, of the wire, may mandate back EMF.

Additionally, Faraday's arrangement takes advantage of the third axis force, torque on the disk, later named after Lorentz.

He also discovered a deeper functioning of a magnetic field, related to his paradox situation. A permanent magnet can be attached to the disk, and still generate electricity when they are both rotated. The magnetic field is fixed in space, or the ether, independent of the rotation of the magnet.

Finally, a permanent magnet can be rotated alone, without a metal disk, to perform the same motor/generator function.

Since everyone is very astute with electronics, maybe you will prefer Vadim's resonating electromagnetic unipolar generator idea.

I am very sorry idea1man for posting off topic and i will try to refrain from that in the future.

The thing about the Coutier device is it is so simple to build unlike the Smith device that took many years just to decipher what the heck he was talking about not to mention the perfect tuning of the device in which i gave up. and yes i still have the main coil (B&W) and the Neon sign transformer.

I am about to acquire a rather large three phase transformer from a friend and maybe by the end of the year i will be able to build this device (Coutier 1932 patent) since all of the legs are the same size i will have plenty of material to accomplish the task.

all my attention is on the Figuera device at the moment but the Coutier and the Walter Russel devices are the easiest and next on the list. these three devices could change the direction of the human race thus tipping the scale back in our favor.

Yes, that Andre Coutier patent is an easy, good idea of multiplying output by simply adding more output coils surrounding one input coil. Don Smith did something similar with his small Tesla Coil surrounded by three matching receiver coils.

This is basically the idea behind Joseph Newman's idea. Make the output coil much bigger. Keely's Rule of Sympathetic Vibration comes in here.

I have my own idea for underground power lines. Simply surround the live power line with many more separate wires that are only connected to the Earth at the power company, but connected to the live end at the substations.

I have read a little on this in my Tesla book i have long ago but i found it lacking of any facts from the author as usual.

give the patent i posted a look see, easy to implement.

      Faraday's generator

As a motor, DC electricity is connected with one wire on the axel, and the other wire on the edge of the disk which is between two, or more, magnets. The disk rotates.

The image, here, is as a generator. turning the disk physically produces DC electricity between the axel and edge.

Unipolar Dynamo Patent: https://teslauniverse.com/nikola-tesla/patents/us-patent-406968-dynamo-electric-machine

Tesla covered the disk completely with an electromagnetic field. Then used a second disk with the field opposite to the first. Therefore, electricity traveled from one axel, up through the disk, across a belt, inward from the belt to the second axel.

Please post info regarding this from Tesla and Faraday and any graphs you might have. sounds interesting.

also look into the patent FR739458---Coutier-1932 Self- generating perpetual of electrical energy. it seems easy enough to make or demo rather.
