To cut to the chase I have been attempting to figure out the device which this German patent describes (https://patents.google.com/patent/DE102006054568A1/en). These are the main points:

  1. At present, electric power is generated by generators that convert mechanical energy into
    electrical energy. It is characteristic of this type of induction that the magnetic field of the
    induced current brakes the rotation of the rotor, resulting in that the generator more
    mechanical energy must be supplied, the more current is generated.
  2. The object of the invention is to produce electrical energy, the magnetic field of the induction
    coil only very small, ideally has no effect on the energy supplied to the generator more.
  3. the polarity of the magnetic field is not changed
  4. capacitors can be connected with coils to the phase shift of current and voltage to change or to
    form resonant circuits.
  5. The apparatus for carrying out the above method according to the invention characterized by at
    least two coils which generate magnetic fields, wherein the supplied into this coil voltage such
    effect that a coil just has a maximum magnetic field while the other coil has a minimal or no
    magnetic field , These coils are matched by its winding direction, the polarity and the time
    course of the injected voltage that their magnetic fields that are coupled magnetically with at
    least one other coil, that produce a rectified voltage, in this further coil wherein the magnetic
    field of said further coil the they causing magnetic fields hardly, no longer opposes ideally.
  6. The method of the invention allows an induction of electric voltages, whereby the generated
    energy of the applied energy is no longer or hardly counteracts this and consumed thereby.
  7. According to Lenz's law an induction voltage is always directed their cause counter, which
    results in the inventive generator, that the magnetic field generated from the secondary coil at
    the rise of the magnetic field generated by the first primary coil pair itself generates a magnetic
    field whose polarity to the magnetic field of said first primary coil pair is directed against.
    However, since the magnetic field of the second primary coil pair is being weak due to the
    supply voltage, the magnetic field of the secondary coil is rectified to the magnetic field of the
    second primary coil pair and therefore forms a common magnetic field with this what to leads
    that the magnetic field of the first primary coil pair is not or hardly through the magnetic field
    secondary coil is attenuated.

The setup:

We have a closed core with two primary coils arranged in bucking mode (same poles adjacent) and a secondary coil between the primaries. The current is pulsed DC and phase shifted 90 degrees in one of the primaries (capacitor).

How does it work:

The magnetic fields in the primaries are continuously ebbing and flowing. If the magnetic field of primary A is increasing in strength then its partners magnetic field is declining in strength. Therefore the secondary forms one pole in opposition to the increasing magnetic field and the other pole is attempting to brake (attraction) the declining magnetic field.

The magnetic field in opposition to the growing magnetic field forms the cemf. The magnetic field in attraction with the declining magnetic field is against the cemf magnetic field. Over the course of a cycle sometimes the force of attraction is stronger, sometimes their the same and sometimes the force of  repulsion is stronger. The net result being that they cancel each other resulting in the absence of cemf.

Rough Schematic:

See attached.

I would like to hear what others think. This originates from overunity.com. Somebody called Fernandez claims to have replicated this (or his interpretation) and gave out some hints as to how it was done. Unfortunately it hasn't got the interest I think it deserves.

Hi p75213 Welcome on the Forum! Transformers are an interesting subject for investigations and relatively easy and inexpensive to built.If you decide to replicate the device I'll follow, as I am working with different transformers too. According to the schematic it works on a rectified sinewave,, and the faseshift of the capacitor is 180°,not 90°. Regards Vidura.

Hi guys! I think this transformer deserves a try. It will probably be one of my next build. If someone else replicates it please let us know about your results...

Thank you for bringing it here and welcome!! 😁

A few more things I thought of.

  • Fernandez recommended a soft iron core.
  • He also mentioned that dc pulses could be used instead of rectified ac.
  • As we're using dc pulses or rectified ac (dc) and in light of the following quote from point 5 in my original post "a coil just has a maximum magnetic field while the other coil has a minimal or no magnetic field" then the phase shift would be 180 degrees. 180 degrees of a dc pulse ie when one pulse is at it's peak the other is at its low point (thanks Vidura)

Welcome to the Forum!

An interesting patent. however I don't see a means Energy "Generation" as we require. Perhaps if the Input was the Output and the Output was the Input, then we would have a different storey!

So, the marked R1 would become the Input and DC on the output!

Yes DC Pulses would work.

Welcome to the forum and thanks for sharing P!

Looks exactly like a Figuera built attempt i came across years ago.

Interesting, out of the box and you could be right.

In this case the magnetic fields in the secondaries would be 180 degrees out of phase and in bucking mode with each other. One pole of the primary is repulsing it's secondary while the other pole is attracted to its secondary.

Can you explain why you see this as being preferable?

It would be easy enough to try both methods.

These are the hints given by Fernandez:

Here is the truth, take it or bury it
I will keep this short and drama free, the words Free Energy, Overunity, and Zero Point Energy has corrupted your thoughts because the device is............ so easy you will laugh

For starters your statement is incorrect Lenz's Law is actually a blessing, you need to wrap your head around that first. Let's review Lenz quickly

Quote "An induced electromotive force always gives rise to a current whose magnetic field opposes the change in original magnetic flux."  

All of you globally have missed the key word in that statement, you are too quick to denounce Lenz's Law as the culprit, the destroyer of energy. However, if I highlight just one word in that statement we open up a new method of utilizing Lenz's Law.

Quote "An induced electromotive force always gives rise to a current whose magnetic field opposes the change in original magnetic flux."  

So the beauty is, if I create a magnetic field in a coil with some current NATURE rewards me with a duplicate magnetic field that opposes mine. Already I got something for almost nothing. (BTW... that's my first Primary coil usage, to create a Lenz induced field)

So I now have a Primary magnetic field that gave rise to an induced magnetic field as stated by Lenz. Pay close attention here, this is important! Now take another coil (call it Primary 2) and feed your Lenz induced magnetic field so you complement its growth. So in other words your North pole of Primary 2 faces the South pole of Lenz field (or Vice Versa). Because Lenz is only present in change of original magnetic flux. Are you starting to see? Lenz has no interest in my second Primary because Primary 1 is the parent of Lenz induced field. You really need to appreciate how powerful that statement is. Ignore what has been written in any other thread that talks about these devices, lots of people using big words and way to complex algorithms to build something a child can assemble.  

So do you now understand why Barbosa and Leal explain in their patent the pole of the induced complements the primary pole? Do you now understand why that guy Tariel says........ it's so easy you will laugh, see why Clemente Figuera said "this is like the egg of Columbus". Because it really is that silly and simple, you simply feed the induced magnetic field with another magnetic field. There is no Lenz that opposes Primary 2, Primary 2 doesn't create an induced field (if you time it right) it ADDS to what has already been induced from P1. The result is a strong Rectified Magnetic field. That is your resonator, not so glamorous now that you know how everyone including Steve Mark pull this off. I apologies if you where looking for something more complex or other worldly. Unfortunately many of you will still be looking for a more complex solution because your mind will never accept such a simple solution to a problem that had you perplexed for years. 

That is the theory behind the how it works some of you are smart enough to figure out the build details, but I will get you started. You are going to wind you primary's like a Poly-Phase motor (Yep a Tesla invention) take special note that a capacitor is used to delay a phase (this is super cheap and EZ). These devices use impulses and you need to split the wave in half so diodes are used. So one coil is at its magnetic max while the other is not, also you need to split the wave between coils, so half wave per primary but that is why you are using diodes (or tubes if your that type of guy Steve). Timing is very critical between the coils, remember you are building a resonator and nothing more. 

Like I said before, take some iron from a tire jack and cut the ends off. Get a C-clamp to close the ends and you have a simple core that allows for different coils. To extract you need a secondary but that is simple, wrap it around your low budget iron core, use a thick or thin secondary.

So its up to you and figure out if the primary's should be CW or CCW, shouldn't take that long. BTW... bifiler coil doesn't mean crap.  The beauty of this device is different inputs (voltage/frequency) changes the output and output varies based on type of coil. Start simple, low voltage and don't kill yourself. You have more in this post then you ever wanted.

One more thing, Tesla patent, 413,353 not glamorous and not your FE but excellent facts and my personal opinion is as close as it gets for Tesla. 



Keep it simple.

Look at the below image, this is how the team started. Here you see two coils over some iron in a C-Clamp. We create a completely closed magnetic field for this resonator (like most others have also). Those coils are not special, they are just coils off solenoid valves (24volts) each is about 340 Ohms. (they are disconnected in this pic) Missing is my Lenz coil, But with this setup one coil must be magnetically HIGH while the other is at Magnetically (or close to it) LOW. Overlooked in my last post was the phrase Rectified Magnetic Field, thats what you need to create and that is what creates the power in all these devices. This is a huge field, much larger then the parts that created it. In the pic I show you 2 of 3 coils that create this field.  

These coils are operated in a similar fashion as a capacitor run motor. The one difference is we are not using pure A/C but rectified A/C (unfiltered) because if you use a smoothing cap you flat-line (no pun intended). 

Let me tell you this, you will never produce power by looking at voltage waves. Draw out the magnetic field lines because you need them to produce power.

Are you aware one of the larger Barbosa & Leal devices requires 2000 watt input? It produces a huge output but what do you think they are doing with a 2000 watt input...... driving a Tesla coil?

 nope .....they are creating a Rectified Magnetic Field.

Hey P,

My Friend, you have it exactly correct!

We have many pages here covering this exact concept and the ways of utilising these concepts!  If you read through some our pages you will see we have many pages, tons of data on this.

Some guys here are way past this initial stage.



P.S: We are completely Troll Free and we enforce this policy, so you're safe here with us, you will not be Trolled, so don't feel as we would bury any Data, we do not work like that! We work on Hard Facts and Solid evidence!

These are my thoughts on this circuit after having read some of the threads on this forum.

It seems the circuit is similar to the Mr Preva circuit. These are the differences I notice:

  • Pulsed dc rather than ac.
  • Both POC's have the same number of windings.
  • The Mr Preva circuit forms a resonant tank circuit. That is not the case with this circuit

 I have included a diode on one of the branches as somebody on one of the threads (I can't remember who it was)  said it was necessary on a pulsed dc circuit if you wish to invoke the Mr Preva effect. Also I'm not sure if the capacitor is needed to give a 180 degree phase difference between the POCs. I thought that was the effect of different direction of windings on the POCs - 180 degree phase shift and the direction of current is opposite the other POC.

I think the Mr Preva effect should be greater on a pulsed DC circuit rather than an AC circuit. The electrons should reach a greater acceleration as they're always going in the same direction. This should result in a magnified magnetic field.

I have included two schematics, however they are in fact the same. Just a different perspective.

Lenz Free Mr Preva

What's old is new again. I found it quite difficult to read the translation as the text colour is similar to the background. He seems to have the Mr Preva effect. However without the 2nd phase shifted coil how is the primary not effected by cemf?

Hi P,

Current Phase shift is very much easier than you think. It may be worth replicating The Mr Prreva Experiment.

Phase shift comes with proximity not necessarily added capacity.

Hi Chris,

  Your right. I also want to do some work with this Figuera look alike and or variations thereof. To be honest I really don't have any experience with electronics and am not too sure where to start. As such I have some questions:

  • Would a cheaper hand held oscilloscope suffice. What are the required features?
  • Can soft iron core be used with pulsed dc? I thought it would quickly saturate. If not what is a good alternative? Also the shape and size.

Hi, P! My apologies for intervening. I just wish to advice against cheap mini oscilloscopes. You would see it's limitations as soon as you start doing some serious stuff. You need good triggering, multiple channels, sample rate, .. There are so many things a mini-scope does not do well.

Hey Guys,

I suggest starting where you feel comfortable and where your budget allows.

CD is however right, reasonable equipment is of benefit, but not completely necessary to start. Viewing Voltage and Current wave forms and understanding what is what and where they are going and what these quantities mean as a whole is very important!

Please start where you feel comfortable!
