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.

Cd_Sharp, this is excellent! Thank you for sharing!

Some very simple observations shot:

  • One Globe is very much brighter than the other!
  • The other Globe, although illuminated, has a lot less Current through it!

This is such an important experiment! I wish people out there could see that have not done the experiment! I have done this experiment several times and learnt a bit more each time!

I think I might re-do this experiment for the Forum also!

Here is my replication of Mr Preva experiment using a nanoperm core and some UTP cable.

I came back to this experiment because I think I need to learn more about it. Here is my basic setup:

with the yellow trace from the MOSFET gate and the blue one from the drain.

 

Then I unplugged the capacitor and both lights get dimmed a little, but the effect is still there:

 

So, the capacitor is not needed for this experiment.

I was unable to obtain current traces on the two lamps. When I tried to connect the scope probes over the two sensing resistors, input current went up and both lamps become equally bright.

I'm thinking that the cause is that the capacitors in the scope probes are generating parasitic oscillation.

Any ideas on how I would be able to obtain the current traces?

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!

Hello Wistiti,

Please consider that little curent in vs. more current out, does not necesarily mean what most people call ''Overunity''.There is also Voltage and the phase difference between Current and Voltage. Do you have an osciloscope? If not, the least you could get is a wattmeter. Now...by putting the wattmeter between the wall and your input you can get an idea of at least the power being put in. If u take the only consumer to be your bulb, than you could judge the power it has flowing thru it by its light intensity(at least for 50Hz is ok), but I would recomand an osciloscope.

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!

All the best!

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

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,

I moved my probes to match this scheme:

and I fed a sine wave at 10kHz to the MOSFET's gate. This is the result:

where the yellow trace is the current on the 11 turns branch (weaker) and the blue is the current on the 7 turns branch (the one with the brighter lamp, the stronger). It looks like there are moments when the weaker branch has 0 current, but the stronger one is almost continuously having current.
