I found the article below in a rather obscure search and want to share it although I have doubts about it working and how. I welcome discussion about this and seeing it would be very simple to try maybe someone already has the parts to try it unless you think it's completely bogus. I'll post the entire article below and attach the simple circuit pic but I'm skipping the scope shots for now that were included in the article. If there is interest I'll post them too. I have no idea who wrote this or where it came from but it does reference a concept Stefan made public as well as a couple others whose ideas this person used. Here is the article :
FREE ENERGY AC GENERATOR
Introduction:
This device is based on some free energy ideas that finally seems to have
something in common:
- The “split the possitive†idea by Edwin Gray.
o It uses a battery and a circuit to get high voltage from it. The
circuit is comprised of Ls and Cs. Then, he let the stored high
voltage energy to return to the low voltage battery again (so
almost no waste of energy), and he uses electrostatic induction
caused by the storing and releasing of that energy to power an
inductive load.
- The parametric power conversion ideas by Stefan Hartmann.
o Changing the parameters of Ls and Cs in time, the energy
changes. The usual method is to keep the Ls and Cs constant,
and change the charges in time.
- The electricity generating apparatus by Harold Aspden.
o Using Ls and Cs, it is said the energy oscillates and can power the
load, because it is energy of the vacum.
The common elements are Ls and Cs.
Theoretical explanation:
Electric circuits work by depleting voltage differences. We have a voltage value
on one side, and another one on the other side. Then, as the charges move
through the load, the voltages become equal, and the transfer stops.
Imagine two equal capacitors, charged at the same voltage. No transfer could
happen.
If we use a switch and a transformer of 1:1000 ratio (for example), we could
charge up one of the capacitors at a different voltage level from the other
capacitor. The transformer and the switch will waste only a little work. So we
can get voltage difference without wasting energy, just by changing a dynamic
V-I ratio, keeping the same energy.
With the switch-transformer circuit, the voltage of one capacitor will decrease,
and the voltage of the other will increase. The energy involved will remain the
same, but will transfer from one to the other capacitor. Energy will not change
on the system, but finally the potential will change.
The transformer is like a “free water pump†because changes the V-I ratios on
the capacitors. It doesn’t increase energy, but changes the place where the
energy is stored, and the final potentials. Now, as we have created a voltage difference between the capacitors, we can
power a load by “discharging†the difference on potential levels on capacitors
and finally get the initial voltage difference again.
So the transformer creates a voltage difference for free (keeping the same
energy on the system), and the load depletes this voltage difference getting
power. The step-up stage on the transformer is a “free†potential change, we
have to do almost no work to get the new voltage levels.
Circuit:
That is the basic idea of the circuit below:
Parameters:
Transformer: K = 1, L1 = 8900 turns, L2 = 1000 turns.
Capacitor C2: C = 33uF, IC = 12V.
Capacitor C1: C = 33uF, IC =0V.
R load: from 9000 to 900000 Ohm.
The idea is to achieve an oscillation, and then, by using the idea of the
transformer free V-I change. The transformer stage changes the potentials on
capacitors, and the load stage is powered trying to equalyze the capacitor
voltage levels.Interesting results:
The values of the Ls and Cs are intended to get 50 Hertz signals.
Firstly, the current on the load gets a high value, then goes decreasing:
But it does not decrease to zero. A little oscillation is maintained:For 9000 Ohm, the voltage is:
Some interesting things about this circuit:
- The load value is important. The circuit seems not to work to lower
values of ressistance. Then i worked with 9000 Ohm to 90000 Ohm
values.
- Once started, the current on the load have always a peak value of
200mA. It doesn't matter if the load is 9000 or 900000 Ohms, the current
peak is about 200mA. So it seems the current value on the load
depends on the rest of the circuit parameters.
- Also, the current is independent of the initial peak on C2. Using a
higher value, we can extend in time. We can get energy on the load for
3 hours with an initial peak of 220 V on the capacitor C2.
Another interesting thing is that more energy is extracted as the load
grows up. For example:
R load = 9000 Ohm, V = 1800V, I = 200mA, 360 W for 1800 seconds.
R load = 900000 Ohm, V = 200000, I = 190mA, 38KW.
Example:
You could charge C2 to 12 V from a car battery, and power nine series
connected 60W light bulbs with AC power for half an hour!.
Conclusion:
I think the energy extracted has nothing to do with the initial energy stored on
the capacitor.I think a dynamic V-I changing proccess is involved, and allows us to extract
energy, only by “voltage equalizyng†on load part. The “voltage de-equalizyngâ€
part on transformer takes no energy, and is for free.
Energy stored on capacitors does not increase, but voltage changes, the energy
stored re-orders on another voltage conditions, and the new voltage values
depletion is the power on the load.
To me it’s as if we could rise a stone on gravitational field for free, then let the
stone fall on normal conditions. The transformer part is the “free-riserâ€, and the
load is the “potential-to-kinetic†part.

Thanks for the heads up.
I found the article you posted on scribd at http://www.scribd.com/doc/8959124/Free-Energy-AC-Generator and the same information and scope shots were there.
I did a search on the transformer model number k3019pl_3c8 and the top hits were experiments in spice... Seems as if it's a spice emulation and should work according to the program so the worst you could do is replicate it and see if it works!
There's a couple of unknowns on the diagram and the description though:
1. Doesn't indicate which side of the transformer is the primary or L1.
2. Mentions charging C2 so is that the input for L1?
3. What kind of Caps are C1 and C2? There are many different types.
There are other items but it seems like it would be easy enough to try it as long as the components can be found.

Hmm, a resonant trafo, look like Rotoverter/Transverter stuff I have read the whole PDF like "Combine.pdf" etc,etc. They use a so called diode pluge to extract power without reflecting back... I search another way to use the 3 Phase PrimeMover Star connection system and use it in 3 Phase trafo in solid state mode...
Another way, in your schematic, I fear when you put a load you detune the system, and you must under magnetize the trafo, (to enable resonance build up voltage/intensity) if your trafo is 480V feed it with only 120 volt (or raise the frequency)...
I have searched about RV or TV specialist to share and discut my diagram and idea, I have found a certain "Ashtweth" but it seems he is not online anymore :-[ ...
@e2matrix:
Since some time I experiment with picking up electricity from the omnipresent RF-smog, specially in the 50 Hz range (from the 220 Volt power grid) and in the 0.1 GHz to 10 GHz range from FM-Radio-stations, mobile Phone towers and the WLAN-points.
The circuit you propose will pick up energy from the 220 Volt 50 Hz power grid (in Europe, if I remember correctly, the US has 110 Volt 45 Hz). The trick is careful tuning into resonance and a good ground connection.
In the 50 Hz range, many diodes will work, but in the GHz range one has to find really fast diodes. Eventually you need at least one diode to drive a DC load like a LED or a little pulse motor.
My experiments did not give good results, so I do not want to talk about it now. It would only confuses the issue (because I am still very confused and do not really know anything useful, just hints and speculation).
But I can tell you, specially the 220 Volt 50 Hz grid floods your building with energy that can be picked up to drive little loads with up to 10 Milli-Watt. And if you are near a WLAN or cellular phone tower, the energy is also comparatively high with a possible useful output around some Milli-Watt.
I speculate that many over unity experiments which show a little over unity pick up power from the omnipresent RF-smog. The energy in that RF-smog is higher than one would think in the first place. And many oscillating circuits pick it up specially when they have a good ground connection. Sometimes touching a circuit provides enough ground to see the effect. Touching also tunes the circuit sometimes into resonance (do not ask me why).
Greetings, Conrad
The numbers from the article are based on Spice simulation with K=1 (couple factor of the transformer).
In practice this will never occur according old school theory. There are always core losses to include, so K<1, which will cause dying out of all signals.
If core losses could be compensated by an external energy source, this could work of course.

@ teslaalset
Thanks for the information, by your statement that "If core losses could be compensated by an external energy source, this could work of course." you got my curiosity peaked, I was thinking of feeding C2 as mentioned but only as ON/OFF pulses to save power and make the R a variable to tune.
My questions in the above post for the component types still is a problem for me and any help from you or others skilled in the art of electronics would be appreciated.
What kind of caps are they?
Where do you get the transformer k3019pl_3c8? I can't seem to find it when doing searches by part number??!
Where is L1 in relation to the capacitors? They aren't labeled on the circuit, the only thing that is mentioned is that you would charge C2.
Sorry to repeat the questions but I'm still puzzled
Kind regards,
Paul

Thanks Goat and everyone for the input. At 33 uf they sound like they'd be electrolytic but of course that's not a given just a guess. Either way the circuit is simple enough it wouldn't take a lot to try nearly all the combinations and even a couple different capacitor types. I tried one setup but my caps were way higher capacitance and the transformer probably not even close.

Yes I see that EMF energy around a lot and it can provide small amounts of power. I'm looking at another circuit right now with nothing more than a big antenna, ground, 1 capacitor, neon bulb and an SCR that can charge a car battery apparently. I just need to string the antenna as I've got the components. It looks a lot like one of Tesla's circuits except the spark gap is replaced by the neon bulb.

Thank you e2matrix, I 'll take a look at this.
Reading the original article, I notice a few things:
- the components are chosen such that a resonance frequency of 50 Hz is targeted.
- The transformer is a basic transformer available in the student version of PSpice, so it's a non commercial transformer, just a Spice code. The type nr. does not refer to a commercial available transformer.
As far as best capacitors, I wouldn't prefer elco's. They have rather high loss. Best choice in my view are the types made of metal foil which do not have a voltage preference. Available values are a lower than those of elco's (nF ... 2 uF).
I think the whole circuit could well work at reasonable higher frequencies.
For those who would like to tune the design a bit to their own available components, I advise to download the free student version of PSpice and play with the values. Very educational and not very hard to do. I'll see what I can do to post the PSpice circuit file here later this weekend.
I did an attempt to copy this model into Pspice.
However I am struggling with the nonlinear transformer model. The default library has a nonlinear transformer available, but I am not able yet to get the model simulated (transient simulation).
Anyone with knowledge on modelling non linear transformers in PSpice is invited to help out here.

I second that. PSpice is a great software even as it is (the student version). Too bad some of us didn't know about it (thanks are due to @poynt99) and had to struggle unnecessarily with the frugal equipment at hand.
There are a number of claims that I'd be very curious to see modeled with PSpice, including the one @teslaalset is mentioning. Another one would be @nul-points' schematic he thinks is connected with the Maxwell daemon and, of course, almost anything else electric on this board.
One word of caution -- don't use the tools for data analysis within PSpice. Transfer the data outside of PSpice into a spreadsheet for a transparent data processing.

I found them earlier, but now I have read them in detail.

I wish I could buy some time ;). I report back when I've made some improvements.
@Omnibus,
Good to see you appearing in this thread as well. We might get this model going with everbody's help.
I am digesting your other findings in parallel. I have not forgot about them ;)
OK, I got the model running on PSpice.
Attached the files needed to run it, see the zip file (SOT_nonlin.zip).
This project was made with the latest Cadence free version : OrCAD V16.3 Demo.
It's important the library files are linked correctly.
This is done via the menu 'pspice', Edit Simulation Profile' and then go to the tab 'configuration files' and link the lib files used (see below figure)
In the model attached I used the non-linear transformer in the 'breakout' lib.
Then you need to rename the transformer to 'kbreak' as done in the attached files.
Intriguing to see: there remains a permanent oscillation that delivers power to the resistor.
[update]:
Also attached the excel file that contains the output data (SOT_nl.zip)
@teslaalset,
Thanks for posting these data. Unfortunately, I can't open the file SOT_nonlin. Gives me an error saying 'Attempt to read file with invalid file format'.
Can you grab all the files and zip them together?

I don't know what to do now because I'm not sure the new version is backwards compatible and I don't wanna mess up my files. At the same time I'd like to study what you've done.

@teslaalset,
Thanks a lot. Download started. Will see how long it will take.
I wonder, what's the benefit of using 9.3 rather than 9.1? The latter is easily found and installed and that's a plus for having these OU claims tested by as many people as possible. Any little obstacle, such as software not readily available, deters people (I know I won't bother). The situation OU research is put in is bad enough to add new obstacles to it, don't you think?

Yes, it's a bit awkward all these versions of Pspice.
I had a look at the V9.1 also, but I like to include commercial component libraries, to be able to use real component spice models as well. That is why I start using the free version of candence.
This is the disadvantage of remote cooperation I guess. Let's see whether you are able to download, install and use the same version I use. I looks like you will be able to use the two versions in parallel. I was able to use your V9.1 version files in the Cadence, so it seems there is some backward compatibility.

I use Windows 7. No crashes occurs.
Maybe you can just start a new project and create the same circuit from scratch. Shouldn't be that much effort.
No, it's not that kind of crash. It just says there's a convergence problem, so something's wrong with the parameters. I'd like to reproduce first your results. Can you give me the values of your:
Relative accuracy of V's and I's

Best accuracy of voltages [volts]

@omnibus,
Here are my settings:
@teslaalset,
I got it. Now, I'm simming it from 0.02s to 0.04, having in mind that the frequency should be 50Hz, that is, T = 1/50 = 0.02s. I'm not starting the acquisition from 0s to avoid the inital ripples. The time increment is 0.0001s. Now, the question is what do we really wanna measure here.
In fact, I'm getting one full period T to be 0.01s. The rest is as in your Simulation settings->Options.

We measure the voltage over the resistor in my view.
It isn't clear at all what's going on. Now, there should be some initial input and then it should be taken away. How's that accomplished in the sim? Then, I'm getting some huge amp values. Why? Also, 1/50Hz should give 0.02s as one period, not 0.01s, or I'm missing something.
This is where I'm measuring I and V. Voltage is w/ 10V offset while current is on the order of kiloamps. Do you measure the same thing?

Ok, you may have missed something.
The start situation is a charged capacitor (the left one).
This one is charged to +12V in the initial phase.
Then simulation starts and capacitor charge starts the oscillation.
In my simulation, I monitor the voltage across the resistor of 9KOhm

OK, that's good but when placing 12V next to the cap doesn't the program take it that it remains 12V throughout and there's no discharge? Shouldn't this 12V be just at the first moment and then see what happens. Something like that. I thought there should be some bouncing back and forth between the caps. That's regarding the principle of operation of the sim itself. Also, I'm still unclear about the measured parameters. Current is excruciatingly high, for instance.
The greatest problem is the value of the parameters. Obviously the probram takes these 12V to be the initial condition and then the discharge goes along its natural way. So, that part may be considered settled. However, why is this enormous current popping up? This is the first thing I'd like to understand now.
@teslaalset,
Take a look at this graph. Damping of I and V signals is evident and is as expected due to losses (non-physical values of the current notwithstanding). One would say that precludes any hope for this device being OU, at least self-sustaining OU (unless someone who wants to hold us hostage insists he knows some secret set of parameters that sustain the signal; we won't fall in such trap, though). One lase hope for this device to be OU if it can be shown that the initial energy needed to charge the cap to 12V is less than the energy dissipated across the resistor till the signals die.

Haven't read further so not sure if you have resolved this but you might take a look at a program called Returnil. You flip on virtual mode with it and install whatever you want, use it, then reboot and everything will be back to the way it was before you made any changes. Great program. Also useful if you are uncertain if a program will have a virus or make changes that would be hard to fix. Well behaved program too and newer versions have some Anti-virus in it but older ones work fine.

Also useful if you are uncertain if a program will have a virus or make changes that would be hard to fix. Well behaved program too and newer versions have some Anti-virus in it but older ones work fine.
Thanks for your suggestion but I think we fixed the problems we had regarding compatibility of the programs and now are working on the subject itself. It's very important all the colleagues discussing such issues to have compatible conditions so that technical points won't stand in the way. Thanks anyway, though. Maybe the program you mentioned will be useful in other situations.
@e2matrix,
Sorry about that. I just saw the Returnil program and it's a some kind of anti-virus program and not a substitute for PSpice, as I initially understood. Will try it in due time. Thanks again.

@teslaalset,
Take a look at this graph. Damping of I and V signals is evident and is as expected due to losses (non-physical values of the current notwithstanding). One would say that precludes any hope for this device being OU, at least self-sustaining OU (unless someone who wants to hold us hostage insists he knows some secret set of parameters that sustain the signal; we won't fall in such trap, though). One lase hope for this device to be OU if it can be shown that the initial energy needed to charge the cap to 12V is less than the energy dissipated across the resistor till the signals die.
@Omnibus,
Well my first concern was that anyone could replicate this model besides me.
Now the big puzzle starts why we get these results.
I am not sure yet, I'll do some more measurement simulations.
I agree that in practice, losses need to be taken into account.
The thing I like to learn is how much losses are allowed to just maintain permanent oscillations.
I understand. Yes Returnil is high on my list of great programs but it's just a virtual computer setup - nothing to do with Pspice. Sorry I didn't make that clear. I got mine from giveawayoftheday years ago and then it did not have anit-virus but was just a computer freeze and return or virtual computer. I think there may be a free version now.
BTW, I know the secret set of parameters that sustain the signal.
LOL - not. My brief experience trying Pspice ended when I couldn't seem to find any AC power source to run a sim. I didn't really give it a chance though as I was just too busy at the time. I think I'll give it another try seeing how much fun you and teslaset are having with it :)
Glad to see there is something of interest in this circuit. If it gets to the point where anyone can suggest a good type of transformer to try a real test with I'd like to give this a try. Hopefully with hundreds of transformers laying around I'll have something right here.
@teslaalset,
I think this needs to be taken care of soon too: http://www.overunity.com/index.php?topic=7620.msg189624#msg189624 . That's Rosematy Ainslie's circit. @poynt99 has analyzed it but with some latest version of PSpice that is incompatible with ours, so that version has to be found, unless we're set to make the schematic ourselves. I'd prefer to use @poynt99's files because he's the PSpice guru here. Kapanadze's circuit is also to be deconstructed and analyzed for possible OU, probably Valeri Ivanov's and a couple of other claims. Steorn's solid-state device too.

Haha, lots on the wish list.
I just wanna play with this one a bit more.
It could be a basis to understand the real Joule Thief stuff a bit better.
Glad you could get this one running.
Thanks for the cooperation here!
An update on my simulations.
It appears that the step size of the simulation profile settings are of great influence on the stationary situation obtained.
Below 2 figures.
The first on shows the result of the voltage over the resistor between 1 and 5 seconds, having the default step size (blank input field of the step size in profile settings).
In the original article e2matrix that referred to, the default setting was used.
The second one show the results with step size set to 100 us.
What this shows is that the step size is a critical parameter in the simulations.
Not varying this parameter will cause wrong conclusions.
Next thing I am interested in is the energy consumed in the resistor compared to the energy present in the charged capacitor at the start of the simulation.
This will give a clearer answer in the COP ratio of the circuit. More to come!
B.t.w. I like the way PSpice enables the generation of the B-H curves of the non-linear transformer.
- monitor current in the primary winding
- monitor voltage at the secondary winding
- integrate secondary winding voltage
- plot a X-Y diagram of primary current and integrated secondary winding voltage

Where do you get the transformer k3019pl_3c8?
The turns ratio is approximately the same as a microwave oven transformer.
