This is a re-iteration of some work done here: Chris's Build Entry

I think it is fair to say, not enough Interest was shown, too many Lies were told. We just don't seem to be ready for this as a species!

They say, sarcasm is a metric for potential - Howard Stark

Of course we are! Too many people are not willing to pick up the Ball and Run!

In my effort to expose and get information out to people that do wish to learn, we had several break throughs from people.

Admitted in his own words, many times, then later retracted, Bradley Richard Atherton, aka Tinman did do some useful work for people:



This is real, I did some work to try to get people to follow and investigate, but none did.

For your Convenience and also a Clue:

Not Loaded with Fan:


12.80V * 0.722A = 9.2416 Watts


10.40V * 1.639A = 17.0456 Watts

COP: 17.0456 / 9.2416 = COP = 1.84

Loaded with Fan:


12.80V * 1.356A = 17.3568 Watts


10.40V * 1.633A = 16.9832 Watts

COP: 16.9832 / 17.3568 = COP = 0.98

Why would there be such a difference between Loading the Rotor and Not Loaded?

The time rate of change of the Magnetic Field is the answer! The faster the Rotor, the faster the Change in time of the Flux! The Flux has two paths, the Long Path, all the way around the Armature, and the Short Path through the Rotor, remember this runs in attraction mode, attracting the Flux through the Gapped Rotor Assembly. At this point the Circuit switches in the Fet, and the two Coils become "Partnered Output Coils" as has been described.

The Rotary Transformer does work as I have laid out, it works with the ideas I have shown and there were direct Lies told about the device which I have documented in the above link. Proven with evidence from the original Videos.

The Magnet does the Biasing I talked about. The reason that the RT did not last very long was as the device heats up, the Magnet looses its Magnetism! A problem easily solved!

No Holes were drilled! No secret Wires or Coils were added, all this is complete lies!

If you want it, then there it is!

Parts List:

  • A Two Pole Vacuum Cleaner Motor. Brads was 850 Watt.
  • IRF540 Mosfet
  • 100 Ohm 1/4 Watt Resistor

Some of Bradley's original Circuits:


The below Image was posted on June 27, 2015, now tell me this is not The Mr Preva Experiment!

That is correct,and thus current cannot flow in the direction of the yellow arrow's(through coil A),but only in the direction of the red arrows(to the cap).

Bradley Richard Atherton (Tinman) - Partnered Output Coils - Free Energy

Yes, progressively getting vaguer and vaguer as time went on!


The Circuit I drew that explains the Box:


Its worth noting, Bradley maintained that the Coil was shorted, thus the Coil Shorting Circuit. However, it is entirely possible that the two coils can be phased such that they can be Paralleled, or put in Series!

Note: In the Video, Bradley mentions that this was being researched somewhere out of the public eye. We were, we had a private Invite only Forum, Bradley was member, but not an active one. This Forum was closed due to a problem with a particular person pretending to be someone else. The forum is closed, but still hosted at:

So, Partnered Output Coils, Magnetic Field Interactions, "Generation" of Electrical Energy, Joules Per Second... Its all to do with "Charge" at "Velocity", Kinetic Energy!

What is shown above, is not new! Its been demonstrated many times before! "Dennis Lee - The Humming Bird Motor and the Sun Dance Generator" is one example!


Showing this:


Was absolutely Critical to proving that Denis Lee knew what he was talking about! This is also true of many other devices!

Father Antonio D'Angelo

The coils 24 are wound in such a manner that groups of poles are formed, which have the same sign. In the modification illustrated in Figure IV, two adjacent poles have the same sign, but the next two poles have the opposite sign.

The key is in the Magnetic Field Interactions!

Dennis Lee reached millions of people, making a difference in a time when making a difference was much harder than it is today. I commend him for his efforts.

Today we know so much more, have more control of our lives and surroundings, understand the powers that try to be are struggling to be!

Richard Feynman said: "Simplicity"


We really need to Think Simply, Diakoptics, breaking a problem down to its basic components and analysing individually to build up the bigger picture.

Bradly's Rotary Transformer is very simple! It uses very few components! It "Generates" Electrical Energy! Filling a Capacitor and bringing to brilliance a 12V Automotive Globe...

Current is the Flow of Charged Particles!

This Flow is completely Contained Inside the Insulated Wire!

The Medium Flowing, is charged Particles! Electrons/Ions...

This Flow is Initiated by Changing Magnetic Fields!

The Magnetic Fields Must Oppose! Bucking...

Dennis and many others do not help us to think simply, when vague misleading statements are made: "A special material..."

Three is an Asymmetrical Number, Two is not, it is Symmetrical! We must aim to build Asymmetrical Systems, which we currently do not build!

Bradley's Rotary Transformer is an Asymmetrical System, as are the others above I mentioned.

The Answers are there, we only need see them and their simplicity.

Well, I think it is fair to say if you look at youtube views of those "debunking" and those posting obvious frauds then compare with serious researchers and hobbiests I think you'll find that overwhelmingly human beings prefer stupidity. Let those who don't want to believe remain ignorant. For me all the physics mumbo-jumbo appealing to the second law of thermodynamics is underwhelming proof against when a simple logical proof for overunity exists.

The logical proof is this: If even one inventor who has claimed overunity is telling the truth (i.e. not lying or being ignorant about proper measurements) then the phenomena must exist. Also all the debunkers reveal the depth of their ignorance since they don't even understand a basic logical premise that the ability to deceive is not proof of deception. It takes very little effort to intentionally fail at this and its hard to succeed even when trying your best... It doesn't help that our mentors love tormenting us with their riddles.

Hi Zanzal - If I am considered a mentor, I most certainly hope I do not talk in Riddles?

There is a certain, required understanding that must be obtained, this is true, before a greater understanding can be obtained. But I most definitely try to be clear and to the point.

Others, other researchers have most definitely left riddles. I personally think this is mostly due to a lack of understanding of what's going on. But I think, as time goes on, a better understanding is obtained by the Researchers, the over all understanding becomes clearer. Then more clear is the information presented.

Some information is designed to be misleading for sure, to throw a red heiring, to put others off track. This could be put down to Monetary Indulgences, E.G: Greed - I will have no part in that! Greed is the root of all Evil!

I agree, there is so much proof now that anyone Debunking is Ignorant and Stupid, none can help Ignorant and Stupid!

Bradley even agreed, and explained that the Coils Buck. This was put down in the Videos and can not be taken back!

We do know better, the truth, we have seen the light!

I don't know Chris, as ignorant as I am most of what you post translates as "wax on wax off." Gotta keep winding those transformers.. It doesn't help that some of these devices are rather expensive or difficult to engineer and without a solid understanding of the method by which they operate its not clear how much deviation can invalidate the entire replication so its a lot of research, then investing, then back to the drawing board. I tend to latch on to those concepts that I can tackle with my skill level for which I have some idea of how they might operate or use parts salvaged from previous experiments.

I used to think resonance was some sort of overunity misdirection and after reading many of your posts about resonance, I think I am actually starting to understand its importance, though the why its important escapes me. The gut feeling that something interesting happens when the capacitive and inductive reactances are equal within some of these devices. Also I totally agree with the idea of asymmetry. Experimentation has shown that some of the "practical design" rules instilled in basic devices are outright the least efficient way to do something. Go ahead put that snubber diode in your motor, because getting rid of those evil induction spikes are totally worth the loss of efficiency. )

There is a bit of tongue in cheek hand wavy claims and misdirection that is forced upon us since the implications of total transparency are largely undesirable, but we know that such claims shouldn't be a distraction to serious researchers. It is rather unfortunate and undesirable. I agree though that greed and selfishness is going to be a waste.. The evidence is clearly against any profitable motivation. The only reason to do this is for truth and truth alone.

I think from your perspective you are as clear as you can be. Its not your fault if some of us are still wearing our blindfolds. I always learn something from my failed replications. I''m hopeful one day I'll learn how not fail.

Chris posted this 10 July 2017

Zanzal, an excellent Post. It tickles me how we, all of us here, are so similar.

Stay tunned, will post to another Thread: Resonance.


Wistiti posted this 11 July 2017

Hi Zanzal, do not worry you are not the only one who is still learning with these "technical" concept!  It is also the case for me.

Even if I have a small base in "usual" electricity, (I have work as an electrician in construction for one year) I must say the nature of electricity we are looking for is another story then what I have learn at school!! With that say, like many here I learn with my building experiment and the help of other more experimented like Chris.  Happy to have a builder team here!

Hi Zanzal

Yes i agree with your rational point of view. We still have much to learn in this unknown and undescovered field of energy, space, time. Because we simply dont know nothing about energy flow, energy substances, about their dimensionality, their forces and space structure in sub-femto particle world where infinite arrays of unknown variables interacting in that magnificent world of elemental forces and particles.

I agree completely Wistiti,

I am also learning, I consider myself a Student of Life! I honestly believe Floyd Sweet would have seen it the same way! A varying amount of success most certainly does not make anyone Learned, and definitely is no reason to stop learning!

Some Bench work is Required, some experimental work, to see what works and what does not work! Most importantly seeing WHY things do not work! Understanding what is not working!

What we do know:

  • Current must be Flowing!
  • Magnetic Fields must Oppose on the Two Secondaries!!!
  • Input is not affected by the Output - A Lenz Law Free Input - One Secondary Coil Aids the Input, one Against it.
        Note: Lenz's Law is real and valid, it is present in the System, it is a requirement! With out Lenz's Law these devices would not work!
  • The Input Regulates the System, it does not Drive it.
  • Electromagnetic Induction Principles apply! This is a Solid State Generator! The two Secondaries have Magnetic Fields Changing in time!
  • Some Cores are Slugs! See below for some reasons.
  • A Resonance is required. Minimise the Input and Maximise the Output - High Q Factor
        Note: Resonance can be ESR, Wave Propagation, or any other Resonance that can be configured to allow Both Output Coils to Oppose and not affect the Input. DC Switching can also be employed in several configurations. Being Graham Gunderson, Tinman (AKA Bradley), as above.
  • The Right Hand Grip Rule is King! Use it, to show you what polarity the Fields/Current are.

Wistiti, do you have any more to add? I think that's the most important.

Why are some Cores Slugs?

Raselli1's Channel is one of my favourites! He shows the importance of thinking simple! Doing Simple Experiments! Understanding Simple things properly. He is a master of his work!

Its taken Electromagnetic Induction 186 Years to get to Today, it just might take another 186 more to learn all there is to learn about Electromagnetic Induction!

At the risk of sounding like a broken record, I wanted, but have hesitated, to post some Historical information on Bradley's Rotary Transformer.

In our work over at when I exposed who was tied in with who, we did have some successes.

Bradley did his homework and made the Rotary Transformer work and agreed with everything I said:

Many here laugh at, and mok EMJ, but the fact is , he is basically right in what he is trying to put forward.


 Everyone is looking only at the electrical output of my device,and seem to be ignoring the mechanical output that is also there.
 They also dismiss EMJ's shorted coil theory,and although he hasnt shown a working device yet,and he messed up the scope measurements,his theory is sound.




 How closely do you think this is starting to resemble EMJs partnered output coil setup?,as i am seeing some resemblance here.




I think it is time Grum,to answer this question once and for all.

For every action,there is an equal and opposite reaction--and then there is the counter reaction

Open the topic,and lets get ION on the scene ,as he knows his way around calorimetry setup's,and i believe this is the way to show PMs doing useful work.



For those following, with some work, this does work, as we have talked so many times. It does take a bit of fiddling, it takes a bit of understanding!

I wasn't going to post this message, but I think at this stage, we really could do with it. All I posted above is true, it all happened, the device is real. But like I said, a lot of Lies were told, many Lies!

Bradley Richard Atherton attempted to make a mockery of the Mr Preva Experiment some months back. After this post you will see why he tried so hard to discredit me and the Mr Preva Experiment.


The Circuit I posted above, is what Bradley explained to the Forum, at the time of these RT Experiments, however its not the actual Circuit used! The real Circuit used is as follows:


As you can see, this circuit is extremely close to the Mr Preva Experiment Circuit!!! Almost exactly!!!

There is an important Timing that is necessary here. No Permanent Magnets are needed! But can assist in the Action if you wish to spend the time! This is just the Coil and Rotor Configuration!

Again, please remember what Floyd Sweet said, and we confirmed in the Mr Preva Experiments:

In the specific case of positive charges moving to the right and negative charges to the left, the effect of both actions is positive charge moving to the right.

Current to the right is: I = da+ / dt + da- / dt.

Negative electrons flowing to the left contribute to the current flowing to the right.

We have Induction Twice here!


 P.S: I edited the Circuit a few times, please check you have the most current one.

Hey Wistiti, Zanzal and others following - An updated Circuit more inline with the Tinman Circuit, but same Coil and Rotor Config:

EDIT: Re-Drawn for a bit more clarity.

I am still playing with component values, I got it back out of storage to work on it further! To see what works and doesn't.

I moved the Switch to see if this makes much difference, and also the 120R Resistor, where Brads was. No real differences seen. All Components I am using are all scavenged from old Electronics, I bought nothing, I did a deal on my current motors also.

@All Following - If you have not already, I would very strongly suggest doing the Mr Preva Experiment, it is critical in understanding how this works!



Will post more soon.



P.S: I should say, there are a few variations that will work, as mentioned, the Mr Preva Experiment is Key here, follow those ideas and we will find a few variations of the above circuit that works.

Zanzal posted this 26 July 2017

Found a vacuum cleaner motor in my closet. Note to self, don't pull out the brushes next time, soldering them back on was a total PITA.

In case anyone is having trouble with this, I can confirm this circuit totally works. It will take me some time just to understand how exactly, but I'm sincerely impressed with that alone.

Hey Guys, I may be completely wrong with some of this, but it may be useful to know all the same. Just ramblings, so no need to read.

Some Speculation from my research:

  • Brad said he filed the brushes down to cover only one Rotor Segment on the Commutator.
  • Timing does seem to have a bearing, Brush position may be something to think about.
  • Some Rotors are very different in their configurations. In my limited experience, this can make a large difference from motor to motor.
  • There is a chance that a PNP Mosfet may have been used although I am seeing pretty reasonable results with a NPN Mosfet, this may make improvements to timing.
  • Many variations could be possible, we need to stay open minded and what we do see, may not be what we think it is!
  • Electromagnetic Induction has a Polarity on the Coil Opposite to that of Powering a Coil with a Battery!

Some Facts:

  • Brad was able to achieve a COP of 1.84, this is almost twice that of the Input. The Mr Preva Experiment shows almost twice the Current to the Input from Coil to Coil, not from Input to Output. This is an effect of Electromagnetic Induction, Equal and Opposite.
  • Brads Input dropped by more than Half when the Load was switched on. One Coil Assists, one Coil Opposes, Brad mentioned Bucking more times than I can remember, which is what I have been trying to present for many years now.
  • The Speed of the Rotary Transformer impacts the performance a lot, because of the Time Rate of Change of the Magnetic Field, in Electromagnetic Induction, is a variable for E.M.F. See: Electromagnetic Induction Calculator
  • The "Generated" Voltage determines the Current along with the Wire Resistance, Ohms Law: Current (I) = Voltage (V) / Resistance (R) - So if your Voltage is very low, then the Current will also be very low.
  • Don't forget, every coil has a Magnetic Field that Build's and then a Collapse's. We all know this from the Bedini days. Rotary Induction has a Cycle of Voltage and Current. Half Cycle Positive and then Half Cycle Negative, remembering that polarity can switch the Mosfet depending on the stage of the Cycle.

Some more rambling, I was re-reading some old posts today, I came across one from Picowatt:

Quote from: picowatt on June 25, 2015, 12:22:22 PM
Tinman's device demonstrates his work, not yours.

Other than both using wire, Tinman's device and your "partnered coils" have little in common.

Tinman's work has more in common with previous attempts and discussions related to the use of
coil shorting to reduce Lenz.

That said, I find Tinman's results quite interesting and hope he will share more with us in time.


This was something I did not ever expect to see. I mean back in the day, it still is a bit on the nose even now. These comments from a bloke that had no idea how the RT worked then or even now! Picowatt went crazy after all he believed in went out the window when Brad proved the whole lot wrong with only a few simple components and some know how!

I mean, what Brad demonstrated, is exactly what we were discussing and had discussed for a year or so at the time.

  • An Input on an Input Coil
  • Two Separate Output Coils Interacting together in such a way to "Generate" Excess Energy
  • Magnetic Fields Opposing on the Two Output Coils.

I mean from here:

So here is where im at with V3 of the rotary transformer. Adding the bucking coil setup did indeed increase the overall output of the system-both mechanical and electrical. When i say bucking coil,i mean a coil that acts as a magnet that can be switched on and off at the right time. As it is a coil that is being shorted,and thus becomes an electromagnet that pushes against the rotors collapsing field just at the right time. This field also travels around the stator core,and boost the field within the secondary(generating)coil that provides the power for the globe.
So we do have a coil that is bucking both against the rotor's field and also the field of the generating coil.


Brad achieved what he achieved, and I always gave credit to those that I referenced! Always!

Brad did start to do the same, giving me some credit for what I was Sharing, but very soon, it was taken away, then I was not given any credit for the Work I gave freely. Isn't it ironic, how the tables turn! I just love Karma!


Edit: I am adding a parts list to the First Post.

Brad maintained all along that one Coil was shorted, which is completely valid for Bucking Coils.

Remember both Magnetic Fields must Oppose!

Bradley tried several times to tell people that he had something working:


Seemed he was wanting to get it out, that he had achieved something amazing! Something that most would never see in their lives.

Examining the last post, there in lies a few clues:

Adding the bucking coil setup did indeed increase the overall output of the system-both mechanical and electrical.

So, Brad took my advice on Bucking Coils!

When i say bucking coil,i mean a coil that acts as a magnet that can be switched on and off at the right time.

We know this for sure, there is a timing to this, and without the Timing, the device is not always Over Unity, this is also true of Graham Gundersons device.

As it is a coil that is being shorted,and thus becomes an electromagnet that pushes against the rotors collapsing field just at the right time.

Surely this is a key sentence!

This field also travels around the stator core,and boost the field within the secondary(generating)coil that provides the power for the globe.

Makes sense, we have seen this in the Mr Preva Experiment!

So we do have a coil that is bucking both against the rotor's field and also the field of the generating coil.

This is why the Input reduces, from 2+ amps to > 1 Ampere

Surely this statement would be perhaps the most important:

Using the bucking coil configuration, coupled in with PM's on a stator that attract an electromagnetic field of a rotor,but appose the generated field of a generating coil,it would seem that the overall output has exceeded that of the input-

I hope this helps some!

I think you are right about the modifications to timing and winding direction. The off the shelf motor is going to need modifications to boost the output power up but I also noticed that the motor can run with power only to the rotor. The only way that makes sense is if it begins functioning as a transformer. So essentially what he built was a partially mechanical overunity transformer.
