You know what? I think you are right. Non of the OU looping systems that use this principle are real and there are more than 6 that I personally know about ranging from 100 watts to over 2kw OU RV systems  plus Thrapps 900 watt generator.
It must be all a dream

Sh$t now what we going to do?  The world is doomed its all been a lie..

Perhaps we should sell everything on ebay and buy some extra candles and matches instead for when the lights go out.

Yes, How about I stop by and check out the one running your house?

I bet it's just awsum or awh shoot, or what ever!

Well if nothing else you are right about one thing, It sure has been tried a lot!

I especially like the latest one from Magnacoaster that works on this same principal, it even comes with solar panels!

I believe the PF is important, but it is not the sole cause of OU.

Hi all,
I want to draw your attention to another way of looking at the speed-up effect.

Maybe you agree that:
when (the generated) current flows through the generator-coils, the magnetic fields of this current interacts with the magnets.

If this interaction is "normal", one can call this current 'Lenz-current', and the effect of the current flow will be that the rotor slows down.

If the phase of the current is shifted just right (think 'power factor', thing 'impedance', think 'reluctance')  the rotor may probably not slow down. It might even accelerate, if enough of the current is delayed to flow at the right time. (thanks bolt, thanks Jdo300)

Now, how much current do we have, flowing in the generator coils?
I am quoting from the German wikipedia topic "Schwingkreis" (tank circuit)
http://de.wikipedia.org/wiki/Schwingkreis

Nahe bei der Resonanzfrequenz ist der innerhalb des Schwingkreises fließende Strom wesentlich größer als der Strom in den Zuleitungen

in English:
"When operating close to the resonant frequency, the current flowing in a tank circuit is significantly higher than the current in the supply lines."

and another quote from from
http://de.wikipedia.org/wiki/Stromresonanz

Die Ströme erreichen für den Fall, dass wL = 1/wC < R Werte, die größer sind als der von außen durch die Klemmenspannung getriebene Strom

in English:
"If the condition wL = 1/wC < R is fulfilled, the currents in the tank circuit reach values, that are higher than the current that is driven by the supply voltage."

That is to say: when properly tuned (i.e. delayed), a part of the current wave in the generator coils will drive the rotor, and there will be enough current flowing in them.

Yes Oscar,

This is EXACTLY, what I believe is happening. I know some here were a bit put off by the extensive discussions about tuning the coils to resonance and all that, but if one understands that this is the fundamental effect that is causing the "anomalous" speedups of at least 5-6 confirmed replications, then I feel that is is well worth the technical discussion to help everyone really understand what is going on here.

In RomeroUK's setup, a tuning cap is not necessarily needed, BUT, the same effect is at play here. Even if you don't add a tank cap to the coil, the coil itself still has inter-winding capacitance, and it's own natural resonant frequency. This is why most of the people who have seen this effect in the past have observed it in high impedance coils, This is because in these types of coils, the natural resonant frequency is low enough that it can be reached at mechanical speeds.

But, if you understand the principle, you can take any coil off the shelf and tune it to run at the frequency of your motor to easily reproduce the same effect.

I am aware of at least four different mechanical FE device claims that all boil down to the same effect.

Thane Heins - High Z coil, accelerates generator under load.

Steven Ward's "Wardforce" generator - Same thing. Generator accelerated the prime mover once the rotor speed was above a certain threshold velocity.

The Mini Romag Generator - Claimed to accelerate on it's own once the RPMs of the generator went above a certain critical speed.

Timothy Thrapp - Delay Line Generator

There are even more but these are the ones that first come to mind. I believe that we all have the key here. It's just a simple matter of testing it out.

Now, for those of you who would prefer to stick strictly to the RomeroUK's circuit, you can empirically see what the resonant frequency of your generator coils are without a cap. Simply take a small coil, put it close to one of the generator coils, and apply a pulse to the small coil. While doing this, observe the frequency at which the generator coil rings as it oscillates. The frequency of the rings will roughly correspond to the natural resonant frequency of the generator coil. This will give you a rough idea of how fast your motor needs to spin before you put a load on the coils to get the acceleration effect.

I'm not sure if anyone has used soft iron for the cores but if you are aiming for your first replication and you want to stick to the original design, I would use the ferrite cores since everyone who has been getting results has done it using those.

Thanks.. I just realized that soft iron is different than iron powder.. I agree, I'm going to use ferrite.
