I think this is perhaps one of the most important experiments anyone could do! A huge amount of information can be learned by running this very simple experiment!

The MrPreva Experiment Circuit

Please Note: The Current's (I), add, Floyd Sweet talked about this specifically:

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.

 

The total Current, is the Sum of the both Currents!

 

We see, 2.8 Amps (da+ / dt) + 2.3 Amps (da- / dt) = the shown: 5.1 Amps as Floyd Sweet told us.

We see a Negative Power Factor, where the Voltage (V) Current (I) are out of phase by a Degree, which results in a Negative Power Factor!

cos(theta)

Where theta is the Phase angle in Degrees. EG:

cos(180) =  -1

 

You will see there are some problems with the MrPreva Circuit, and it is explained, because, the Current (da- ) has become a Generator, or a Battery, which is the only time  Kirchhoff's Current Law does not hold in an applied situation.

Hello everybody,

I am attaching my Mr. Preva experiment. 

Everything is shown in the pictures and in the video at the end.

I measured the currents of both coils through 0R1 resistors and I used a hall current probe at the input to the circuit. As you can see in the video, changing the inductance also changes the phase shift. 

 

And the result of the measurement

 

Scope measurement:

Blue - current L1

Yellow - current L2

Green - input voltage

Purple - input current

Have a nice day.

Hello All!

 

The last couple of days I have done some tests with  different coils to replicate the Mr Preva effect, using the new Switching Tool. But to my surprise the effect was not present, although I used various different coils, cores, frequencies  and capacitors. Then I hooked up the audio amplifier, feeding a pure sine wave but still nothing, a couple of times very unstable it seemed to be present, but it resulted to be  false readings due to double triggering of the scope. So I thought what is going on here, haven't I done this many times before ? The problem was that I sometimes have failed to document my experiments properly, the issue was very simple , I made the same mistake as in my first  replication intent's : A reversed connection of the coils. The reason I post this here is that maybe it can help for some to avoid to make the same mistake , and hopefully  to understand more clearly the principle of the opposing fields and Lenz' Law. Using my (mistaken) logic I connected the setup in a manner that the magnetic fields according the right hand rule opposed, BUT in the conventional current direction not 180ª out of phase! The correct polarity is that the fields must oppose when One of the coils has the opposite current direction(when the effect is present). When I corrected the polarity of course all the coils showed the effect clearly, also with the H-bridge and short square wave pulses good results as with sine AC.

 

 

 

For a clearer understanding of the effect just imagine a conventional transformer under load, the current in the secondary produces a magnetic field which opposes the primary field(bucking equal magnetic poles), thus the reduced impedance effect makes the primary current rise.  This is the well-known Lenz Law.

 

Now in the Mr Preva experiment we have to understand the timing  and how the inductors behave when potential is applied. Any inductor when a voltage potential is applied to the terminals  instantly, before current begins to flow the inductor will have an  equal and opposite voltage, which begins to decay, while the current is increasing. The smaller inductance will increase faster, and the associated changing magnetic field will induce a voltage in the second, larger inductor. Due to the winding ratio the induced  voltage will be greater than the source voltage, and will cause the current in the second inductor to flow backwards  against the source potential and return forwards thru the smaller inductor, adding to the original current. Thus the increment of current in this experiment. 

 

 

 

For the next experiment i will post results in the "delayed conduction Thread", I want to reproduce the reversal of current with equal inductors-windings by introducing a switched delay in one of them.

 

Regards Vidura.

Hi Brian,

Fantastic work! Thank You for sharing!

The Mr Preva Experiment is an excellent step forward for sure! We have worked on the Akula Machines, particularly the Lantern, for a little while. I have some success back in the day, and tried to share some of it. Not many paid any attention.

The video here:

 

If you turn on Closed Captioning and translate, he tells you exactly how to do it!

Remember, the Mosfet is just a switch, thats all, what can be adjusted in the switch, basically only about 4 parameters:

  • Frequency
  • Duty Cycle
  • Rise Time
  • Decay Time

 

Akula tells you how to do it, forget about building Circuits, use a Function Generator, and focus on the above parameters and what Akula told us. He was right!

Yes Primary and Seciondary Buck, Standard Electromagnetic Induction. So make sure this polarity is correct, it needs to be.

Some here have working machines using what Akula told us! This does work!

Initially I belived this has something to do with Electron Paramagnetic Resonance, and still do, but its really not complicated at all, so dont let it get complicated.

Dont waste time on Circuits untill you see the effects, some Circuits on this forum may help once you get the desired effects occuring.

Best Wishes,

  Chris

Hi everyone, I post my replication of Preva exp. that I did a while ago.

schemaversion1

opposition phase20KHz version1

 

in phase100Hz version1

sort of akula coreversion2 sort of akula core

opposition phase5KHz version2

30Hz version2

The circuit was powered with a frequency from 50Hz to some kHZ and I observed that:

When the frequency is below 500 HZ the impedance is almost zero so the circuit is practically a direct line.

When the frequency is above some KHz, the impedance increases and the phase displacement of the two coils increases up to 180 degrees.

another observation: there is a considerable transformation of the current on the shorter coil, this confirms the Preva theory of current amplification, and the circular path of magnetic flux in the core.

if someone can confirm what I'm writing because I've always seen replicas of the experiment with very high frequencies and not as low as the ones I used. thanks

good day to all

Hey guys,

i´ve been very busy the last few months, so I couldn´t experiment anymore. I hope, the next few weeks will be a little unstressed, so I can go on and show some progress. Besides, i´ve forgotten my login data for my old account and the "forgot my password" function didn´t work

Hi all

Now i have made the Mr. Preva experiment so good i can to prove the point,not so as the original where you see the wire glowing on different sides ,but you see that in one branch is more current flowing than in the other and the 180° phaseshift.One coil has 40t and one 60T ,no capacitor.

In the first picture you see the setup with both lamps glowing at 37Hz.

In the second you see the waveform of the current.Both the same 10mv/div,one div.1Amp

In the third the shifted phase at 887Hz.

And in the fourth only one lamp glowing.

Have a good day.

Hi Jagau,

 

Hall sensor which I used in Mr. Preva experiment is from my old simply measurements and was connected to MCU to digital processing. I was only interested in the waveform and the phase shift at the input to the circuit, so I wasn't interested in accuracy.

Its LEM manufacturer and LTS series

You must be careful to avoid overloading and saturating the core.

Now I am working on smal circuit to improve hall sensor accuracy. Simple system to setup zero DC offset and gain of the hall. It could looks something like this (probably its not complete). Power supply must be thermaly stabilised.

And process of calibration could be like this

If you have any other ideas, come here with them wink

Have a nice day.

Cd, Zanzal,

At any one point in time, the Coils in the MrPreva Experiment, Buck Each Other!

They Oppose!

This results in a Gain, in the local Circuit, of almost twice the Current. Try to picture the Magnetic Fields, what they are doing, the Currents, and why they Oppose... Right Hand Grip Rule...

Then look at the other devices, like Don Smith:

For some reason, we, the human mind, has a tendance to way over complicate the simple, We need to force our minds to think simply!

Chris posted this 19 April 2018

Hey Zanzal,

Your question:

Would an induction heater be more efficient if two coils are used in a style similar to Mr Preva?

 

 

Answer to your Question: No, not as it stands.

 

@All Readers:

As we know the Mr Preva Experiment, is Symmetrical, it has equal and opposite Energy Transformations less losses. This is the reason it is, as it stands, Below Unity! Experiment shows: Current is Amplified, but we see a large Voltage Drop!

Electrical Energy is V x I, by loosing one and gaining another, does not constitute an Energy Gain! However, amplifying Voltage does not cost us anything! This is not a Transformation of Energy! No work is done to Step Up Voltage!

The next Step to The Mr Preva Experiment, is my Thread: Some Coils Buck and some Coils DONT

I introduce the Asymmetrical Energy Transformations, where the Input Energy is not affected, in anyway, by the Output Energy. This is the reason I have posted the Thread: Asymmetrical Regauging.

I see many are not seeing what I have been trying to show, many are not following the trail, not understanding posts I have taken time to detail effects and show where the open doors are. Its ok, I am ok if others do not want to learn.

However, if people want to learn how Energy Machines work, they will need to learn, need to start thinking in terms of Energy Transformations, learn how our Environment can introduce excess Energy!

Your Input of X Energy, is never, ever going to Transform itself into 2X Energy by itself!

You must Open a Door for the Environment to Add Energy!

The Door = Increasing the Rate of Kinetic Energy

Atti - Excellent Experiment!

You show exactly The Mr Preva Current Gain! This is a critical aspect of Above Unity Machines to understand.

We loose Voltage, Voltage is consumed by our Load but more critically Opposing Fields, known as a Voltage Drop. An Auto Transformer in Buck Mode is well known for this effect:

 

Auto Transformer in Buck Mode

 

In the above Auto Transformer Configuration, the Secondary Coil "Generates" an E.M.F of 100 Volts, then the output will be 240 - 100 = 140 Volts. We have lost 100 Volts, because we have Bucking Mode in this Auto Transformer.

 

Auto Transformer in Boost Mode

 

In the above Auto Transformer Configuration, the Secondary Coil "Generates" an E.M.F of 100 Volts, then the output will be 240 + 100 = 340 Volts. We have gained 100 Volts, because we have Boost Mode in this Auto Transformer.

So, we have learned that in any Bucking arrangement, there is an elimination of Voltage in Bucking mode. The Kapanadze Coil also is exactly the same configuration, it is only a partial Bucking arrangement. We have conformation of this from Ruslan:

The output voltage will be 195-200 volts. This voltage will not be higher. Why? Later we will return to this. It is necessary to rewind the transformer-reactor (Coil) so as to obtain the desired voltage. This requires experiments.

Ref: Ruslan K

 

Ruslan is a man of wisdom and avail. 

 

 

The Coils Coupling is well less than half Unity Coupling, the turns are 48 CW to 36, a difference of 12 turns. At least half of the coil was uncoupled, or loosely coupled. This is the reason Ruslan said: "It is necessary to rewind the transformer-reactor (Coil) so as to obtain the desired voltage. This requires experiments."

Magnetic Resonance gives us a gain in Current. To achieve this, we gain a loss in Voltage as shown. So we utilise Timing and a Stepping Up of Voltage with turns. But this requires Experiment, something I have also said: "Some fiddling is required".

So, your experiment proves a very valuable concept, that of Current amplification. To get to the next step, a little more fiddling is required. You already have one of the most important concepts!

Hi to all, I was particularly interested in doing the voltage-current phase shift test to better understand
the behavior of the akula core. Since the circuit is inductive, thus the current is delayed respect the voltage.

 misuration 20turns coil

The smaller coil 20 turns test. Trace 1 voltage, trace2 current: delay voltage-current about 25°. Freq: 1KHz

 

misuration  40turns coil

The greater coil 40 turns test. Trace1 voltage, trace2 current, delay voltage-current about 180° Freq:1KHz

 

misuration only currents shift

Here we see the phase shift of the two currents together, the mrPreva diagram with currents in opposite directions is confirmed like above. The smaller coil (trace2) is slightly out of phase and higher current, the greater coil (trace1) is in opposite phase and low current. I did not understand why the phase shift is greater than 180° probably due to inaccuracy caused by harmonic distortion I think.

the next step is to figure out how to apply this to akula, I accept suggestionssmile  hi!

Hey Mich,

Good work on your replication. It has been on my todo list for a long time now to try this replication using AC rather than pulsed DC as I did in the past, but the amplifier I ordered was lost in the mail, and I never reordered. 

You mentioned suggestions which caused me to wonder how Mr Preva would behave if four coils where used instead of two. With two coils for a primary the same as the MrPreva and two for the secondary also an identical MrPreva. Of course this is more difficult to test without an isolated oscilloscope and the results probably not very unexpected.. But you asked for suggestions, so I figured I'd toss it out there for you or anyone else. If I get a chance to test it myself I'll share the results.

Chris posted this 13 March 2019

Hey Mich,

Excellent work! Thank you for sharing your excellent progress!

In my opinion, a critical, most valuable experiment to do, to understand and set a baseline for experiments in the future! Now that you have taken this time, to take the step forward, following experiments will be very much easier and make more sense! You know what to aim for!

I would like to invite you to study and participate in the two threads: Parallel Wire or Bifilar Coil Experiment and Delayed Conduction in Bucking Coils.

Your contributions would be most welcome!

Hey mich.

It is also worth noting that if one of the coils is tied up in the opposite way, how the current strengths on the secondary side.
Measurement.
North-South or North-North roll coils.
When bigger and less power. Why?
Thus it is possible to refer to the presumed presence of magnetic resonance.
Good work.

Hey Mich.

 

- Do not delete any posts.
- Everyone's comments are important, you can learn from everything.
- My intention to comment was not offensive.
-If you can do all the experiments, walk around properly.
Draw conclusions.
Read everyone's comments, but don't trust anyone.
Only in this way can you progress your work properly.
Precise measurement does not always have to be done, often enough to find out what happens in the circuit. The Mr Preva layout is important, but you don't have to wait for a miracle. But the layout must be kept in mind. I'll tell you another example, but it doesn't necessarily belong here.

I investigated Árpád Bóday's magnetodynamic invention.
Take two parts.
-The primary drive with bridge H, with a 25% -25% filling factor per transformer. The remaining 25% should be the fill factor for the permanent magnet line.
-The secondary side switching can be divided into two parts.
Load and backfill.
There is a MrPreva "theory" within a transformer.
24V and 12V. forms of binding. The effect is important. Magnetic resonance is important. The load on the backfill is important.

Yet the road to pleasure is stubborn.

I have been through times of frustration also, same as I see in some posts.

Let me say this: To follow in the path of the greats before us, we must put their shoes on.

Ask simple questions, look for answers, has everyone read the Floyd Sweet Papers? Has anyone read the Andrey Melnichenko works? Has everyone read the Don Smith works?

What are the similarities of these same works?

We need to be detectives, use analytics to measure our experimental success and failures. This gives us direction!

Hello everyone I also tried to do the Mr.preva replication and it seems to me that I have got the effect where one bulb on one coil is brighter and the other bulb on the second coil is weak in iluminus, I don't have scope to see the waveforms. The effect is critical to frequency and duty cycle, I am still trying to understand what's going on the circuit. The bulb is brighter on the coil which has less turns. I tried sine wave and triangular wave but didn't found the effect, the effect I only found on squarewave, Am i going to the right direction or am i barking to the wrong tree ?

Hey Dennis,

Awesome Work! This is really nice to see so many excellent experiments! Tons can be learned here!

In your image:

oscilloscope_lamps

 

The Sharp Peaks in the top trace, in the above image, shows Core Saturation, thus the Phase Angle has been lost, Current and Voltage are in Phase. In the first Image, you show a large Phase Angle, approximately 100 Degrees.

NOTE: Research what occurs when we surpass 90 Degrees. You will not believe what you have achieved!

It is important to see, in this Experiment, we are Pumping Current, the Magnetic Fields, and the Opposition of Magnetic Field, in Resonance, is what pumps Current, First a Voltage is "Generated", the Voltage allows for the Flow of Current, the Current is supported by the Opposition, the Pressure, of Magnetic Fields.

Remember Particle Physics, the Electron Orbital can be Changed by adding Energy to, or taking Energy away from, the Electron, thus changing its orbital.

 

Again, What Is Current? 6.24 x 1018 Electrons past Terminal T1 in one Second = One Ampere.

So the near Doubling of Current in this Experiment, in One Cycle, is simply the Pumping of Electrons on the Outer Orbitals. The Coils, plural, are doing Work! We have an Electromagnetic Charge Pump!

Floyd Sweet said:

The current and potential windings require relatively little power, and are applied in such a manner that rate of flow of moving charges may be accelerated beyond 1 Ampere = 6.24 x 1018 electrons/second. Thus the duty factor of the copper changes.

Losses diminish and more charges drawn from the now coherent space field flow at a faster rate as current to the load. This means as more current is required by varying loads more feedback magnetomotive forces free more electrons from binding forces complimented by potential magnetic forces of the orientated, coherent space field. Thus a conductor that formerly had  temperature rise above ambient labelled as a factor of 10 would now operate at a temperature of 1.0. Thus the same gauge wire would carry 10 times more current at the same temperature.

Ref: Floyd Sparky Sweet - The Space-Flux Coupled Alternator

 

Learning to think like this is extremely beneficial! This is the very set of well defined constants that Power the Load! Voltage and Current. A logical sensible approach in this area is critical for all serious researchers!

Best Wishes,

   Chris

Hey,

Dennis

Hello mate.
It is good that you have started experimenting.
@Chris has made a very good post,Lots and Lots of information / Food for thought.
however.... ,
The problem is the JDS6600, that is also MY Signal generator, and it can output 20 Vpp and 0.02 A (Aprox )
As you can see in the Second picture..the INPUT is 5 V , and you hit the circuit with 20 V.
The DDS Signal Generator makes a STEP UP,and it is trading Current for Voltage.
As the MR PREVA Experiment is not MAGIC,we DO need to hit the circuit with some CURENT else we will not notice the effect.
Next time I will not buy anything if it does not a very specific Instructions and Device details.
I wish you good luck and keep experimenting !!

Hi Team

I came across this site during research on Akula and his Lantern / Flashlight builds.

This site is by far ahead of the field in the quality of information available. I would like to congratulate Chis and all contributors on this.

I arrived looking to understand how Akula was able to extract excess energy from his circuits and i believe the lesson from Mr Preva has turned the light on (so to speak ).

So my first step in this understanding was to raid the parts box, pull out a old scope (yes it is vintage) and knock something up. And here it is.

The calculated Resonant is around 11Khz and the Sig Gen has a 10V p-p output

All worked very neatly with the teachings of Mr Preva

The probes are x10 (I had to repair the x1/x10 set which I have now) The 180 phase difference is as projected.

I had expected the transformers in Akula's various builds to be of a concealed unbalanced nature, but this has demonstrated the possibilities from a simple CW/CCW coil.

Thankyou for the lesson

Hi Vasile, thank you for your reply. If you look one post before the video I post, Chris post an image of the simple circuit I use. The capacitor is not needed.

For your information, I have not say it is over unity... Too much a big word! 

I have an oscilloscope, but not to familiar with it... need more time to learn with it... I also have a killawatt. The idea to share this experiment is to give to other the desire to do the experiment... it is really cheap and I think we can learn with it.

Hope I give you the desire to try it or any other Preva kind of experiment!

Reference?

 


You need to start thinking sooner or later, what is good to keep but to misinform the wrong information.
They are trying to imitate the work of many inventors. Right or wrong.
Chris points out that good information (such as magnetic resonance) should be kept.
Mrpreva case. There is hardly any induction at one of the magnetic arrangements, so there is hardly any secondary current.
In the other case, one of the coils has more current (which will do something again)
For example, the layout is similar. Just like that.
Buy a soldering popper.

Primary current is less than secondary current. Now tie it to the Preva layout. If you would do this with a disc meter
  (which is irregular and punishable !!)  

then the dial gauge rotates faster in one of the binding directions.
At the other binding direction, the disc measuring clock stops.
Why is that? What does the current do with the dial?
But this was just one example.

Personally, I think it's good to think about everything, and of course I try some things. Watching for bad experiments. Because there is plenty of it.

mich posted this 20 March 2019

hi to all, with this I hope to answer Atti's suggestion,

the experiment looks very much like another experiment of an brasilian boy, concerns a kind of resonant transformer.

1

1

Frequency 1KHz. The power supply is via a sinusoidal generator and audio amplifier, the lamps are all perfectly equal (2.7 ohm), the current is detected with toroidal cores, it is not an accurate measure but I am only interested in having an idea of what happens. In this case the current follows the law of the resistive divider so only the lamp with the highest voltage drop is switched on. The traces are currents, 50graus phase shift.

------------------------------------------------------------------------------

2

2

Frequency 7KHz. In this case the situation changes and we have a current circulation between the 2 coils L20turns(blue coil) and L40turns(black coil). In fact, if the lamp is removed from L40turns(black coil) the phenomenon does NOT occur and the other lamps light up together with ANY frequency with identical and halved brightness. It's remarkable that the power is greater on lamp L20turns because as we have seen previously the phenomenon of current amplification is verified. 131graus phase shift.

---------------------------------------------------------------------

Now the current sensing is moved to the common line.

1A

1A

Frequency 1KHz. L20turns current test in comparison with the total current, we see that the power absorbed on the lamps follows again the law of the resistive divider. There is no phase shift, note the amplitude of traces.

-----------------------------------------------------------------------------

2A

2A

15KHz frequency. Trace 1 current on common line, trace 2 current on L20turns (blue coil). The frequency is higher to demonstrate the phenomenon more clearly, it is important to note how much the current that circulates between the 2 coils increases, and how low is the overall current absorbed, (to be confirmed). here too we have no phase shift.

EDITED: I think this exp is important although I have not completely understood the phenomenon. The overall power seems to be less, but in reality there is absorption. Soon I will correct the parts where I made some inaccuracies.

thanks good day

Hi Vidura,

Very interesting indeed. During my experiments I also tried several 1:1 ratio coils. None of them showed any good results (so far).

This seem to confirm your statement about the need for more windings in one coil to create a higher voltage. Why and how this works I don't understand (yet). I will however keep experimenting with the 1:1 coils. My gut feeling is that there is much more going on and we have to get to the bottom of it.

I'm not convinced that the bigger coil should be wound from thinner wire. The best results that I have seen so far come from a type of coil where L2 is wound over L1 on a single bobbin and put on an E core. Similar to what Akula showed. Both L1 and L2 have the same wire size (2,5mm2 stranded PTFE insulated wire) and a 7:23 winding ratio. I could be totally wrong but my personal experience in my devices is that bigger coils with many windings give less output. I speculate that this might be due to heat generation in the coil (increase of resistance).

Hello Chris I understand your position,.  however i do stand by my test results at this stage.  please allow me too prove myself wrong, rather than trust the prevailing winds.

i sincerely hope too be able too prove myself wrong, thus learn something more important than free energy !!. taking competent measurements and living up too my training and military certs.

MAKE no mistake though, - this place has wonders beyond the realms of mortal men. ... that i am only beginning too understand.. let us grow together, - and know that i definitely accept the possibility that i am wrong. but it would be a world first.

Hi Parkham,

There is a variety of information and videos regarding the "MrPreva" circuit in this thread - scroll up to the beginning for a good review of the subject.

 

Of interest is the observation where it appears there is a circuit current in the forward direction of 2.8A, a second current in the forward direction of 5.1A  through the top torroid winding; but most interesting is an apparent reverse current of 2.3A through the lower torroid winding - in the reverse direction. This is shown in the second diagram in the attached pdf file above.

 

A typical circuit of similar type is a simple offset BALUN, thus the reverse current observation is (likely) a new "thing." It will be interesting to discover the fundamental details! 

 

Although Chris and other members know this circuit probably better than most; I do not believe the circiut is developed enough at this point to be of any real practical application. But if the reverse current anomolies have merrit, then there might well be some interesting and useful off-shoots - as seen in the simplified current diagrams!

 

Note that this is but one of the many potential "excess energy" concepts being explored here at AU; however there are a few real proofs that have now been demonstrated. My primary quest, and that of many other investigators here, is to develop a generalized theoretical basis, including the mathematics and experimental evidence, for these "excess energy" devices. Without a viable theory we are still in the dark for the most part.

 

A "valid" parts list will ultimately result through the detailed schematic needed for simulation analysis; so hold off a bit until the schematic is CAE validated or, at least, shows some promise.

Have good one, SL

I prefer to quote Tesla on the last words;

Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. . . . 

     The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories.  The scientists of today think deeply instead of clearly.  One must be sane to think clearly, but one can think deeply and be quite insane. . . 

     The scientific man does not aim at an immediate result.  He does not expect that his advanced ideas will be readily taken up.  His work is like that of the planter—for the future.  His duty is to lay the foundation for those who are to come, and point the way.  He lives and labors and hopes.

 

It summarizes my thoughts

Hey john
Nice demonstration
Did you build your own hall effect probe?
It probably has a precision up to Max 20 khz?

I have already made a probe like that tell me how did you do the calibration, it was the most problem, it interests me
It is very well done
Thanks for sharing your experiment

Hey,

here is my replication of the Mr. Preva Experiment. 

coil: 17.1uH, cap: 1uF --> res. frequency of about 38.5KHz

But as you can see, I was not able to get the lamps glow on the 38.5KHz but on a much lower frequency - and so no resonance. By using just resistors (each 1Ohm) instead of lamps, I almost got the currents to 180° out of phase (last two pictures)

I know, I´ve missed something. But I don´t know what...

Hi Dennis,

I think using what you have got, has worked fine! I think keeping this simple and cheap, only upgrading if you have to, is the best path forward! I think you have achieved a very important milestone! What you have seen, it is very important to understand it!

If I may, read this thread, list the important things you have seen, make a point of knowing what it is youre looking at, learn as much as you can, this is just as important as doing the experiment!

Best Wishes,

   Chris

Anomalous Kirchhoff Behavior

Splitting a transmission line into two branches should divide up the current, according to Kirchhoff's Laws, and maintain the same direction (ie, polarity) of current for both branches, yes?

This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently: The algebraic sum of currents in a network of conductors meeting at a point is zero.

      But what if conventional expectations are not always right? What if, sometimes, anomalous events can occur?

Hi.  I have a few questions:

Input voltage / amps, how much?

Coil wire gauge?

What capacitor to use?

 

Also, what are each of the white blocks in your replication?  Can I see the entire picture?  Like what the wires are running to as well?  It's easier for me to see it, in addition to reading the schematic. 

Thank you,

Hey guys,

I would like to point out that in the following video it's exactly the same phenomenon with slight differences:

 

I guess that the 2 secondaries are in bucking mode...

Hello everybody, maybe mine is a silly question but are the two coils wound in opposite directions?

Thank you

blackboarddd posted this 06 November 2017

Thank you for your welcome and answers!

Can't wait to start testing, anyway my guess is the windings should be opposite...

Thank you Zanzal for the hint. Which core material do you suggest to use for the inductor?

What is a Scalar:

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, and the magnitude of physical vectors in general.

You need to forget the Non-Sense that some spout with out knowing the actual Definition of the word Scalar! Some people talk absolute Bull Sh*t!

The pressure P in the formula P = pgh, pgh is a scalar that tells you the amount of this squashing force per unit area in a fluid.

A Scalar, having both direction and magnitude, can be anything! The Magnetic Field, a Charge moving, yet some Numb Nuts think it means Magic Science!

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
