I would like to repost this from Bolt:  he said this in MARCH!!.  before any of this began.  Seems like the effect that is going on here.  Mr Bolt I wish I knew half of what you know.

Magnacoaster used a pulsed coil of not that many turns about 100 is enough as seen in his early photos. He used a laminate steel core like transformer strips then applied 5 powerful neos one end and 1 the other. This magnet layout is VITAL.

It creates a Bloch wall which sits about 2/3 across for the length of the core. The edge of the coil sits right over the bloch wall. So you need it to slide along so you can find the sweet spot.  When the coil is pulsed the magnetic field is already on the Bloch wall and acts as a pivot point. You can not do this any other way when using such powerful neos to fight against this magnetic field would need like 400 amp pulses so you hit it right on the Bloch wall. This is called  asymmetric magnetic modulation. When the field collapses the neos flux over shoots and generates more power out of the coil than what you put into it. Now coil shorting will help here a lot. I dont know what he is doing now but if you hit the top of the rebounding neo spike with  short you can almost certainly increase the voltage perhaps 5 times more then syphon off ONLY the HF part of this signal will prevent loading to the driver. In practice you would put blocking diodes going into the coil to prevent BEMF reaching the driver then use about 0.01uF in series each side of the coil to syphon off only the HF and use as high pass filter. Then add a HF balum traffo and impedance match down before going to FWBR then into a dump cap.

Thanks

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.

thank you for that great information on how to find the frequencies of your coils

will try this today

How about this method (I'm asking mostly but I think it would work if you have an o-scope and frequency generator) - put a frequency gen on your coil along with an o-scope across a single coil.  Then put a magnet near it.  I'm guessing maybe use a square wave pulse or would sine be better?  Then scan through frequencies until it starts singing.  And look for a jump in size of the waveform on the o-scope.  Unless someone more knowledgeable chimes in on this idea don't take it as any sure method.  I'll try it at some point as it sounds easier for me. 

Hi Folks,

Hi ndh16 and onielsen,

Thank you for your first posts and it is very good you both bring more scientific tone into this thread. Please continue adding any more insight whenever you can.
So a possible explanation for getting extra output over the input is when  resonance is involved with the coils in this setup and the loaded quality factor, Q is maintained above 1 so that the reactive current inside the coils is Q times higher than the input current.  A good chance for this is the possibility that in the steady operation with a load, the contribution of the individual coils by their output is taken only at the moments when their induced peak voltage is higher than the voltage in the common puffer capacitor as earlier this was mentioned by a member.  So this could explain the load on the coils is intermittent and this helps preserve a Q > 1 state.  It is possible that more is involved here, this is one explanation approach.
