I agree that the results were very weird.  I was hoping they would mean something to you because they did not tell me much at all.  But definitely not what I could have predicted.

One thought:  The system is not very acoustically stable and may not be giving good linear results wrt RPM.  There are some passive coils mounted at all times and they have ferrite cores.  I adjusted the inductance of each coil with the ferrite so they have slightly different amounts of core projecting through and closer to the rotor.  There are 3 pairs of single filar coils mounted 120 degrees apart for balance.  But the one bi-fi pair is all by itself.  Also, the ferrite in the bi-fi is projecting about twice as far through the coil end facing the rotor and will be the ones that crash if adjusted too close.  As the system is adjusted with the coils very close to the rotor now, the rotor magnet to ferrite interaction is quite high.  A lot of cogging due to this interaction on even the unloaded coils.  And with these asymmetries, there are a lot of different vibration frequencies in play.  The system screams through many different acoustic resonant states as it winds up and down in RPM.  So where it settles may be slightly affected by the mechanical resonant frequencies of the build.  Plus my bearings may be grumbling through all the abuse as well.

Here is the schematic you demanded and a shot of the scope as it was set up and recording again.  I will not be using the scope or changing any setting for awhile in case you have any questions about the setup there that you cannot see in the picture.  I plan to tear down the mechanicals next to remove the bi-fi coil and set up again with the balanced three pairs of single filers.  Then I can test for COP with different loads and RPM to see if I am even greater than 1 as the cap switching theory suggests.  I figure with the correct load I must be able to achieve at least a COP of 1.334 if I want to have a chance to loop by adding the additional 2/3 of the coil pairs.  This is still questionable with my existing low wind count coils in my mind.

One errata correction:  The load in the previous cap tests was 390 Ohm and not 330 Ohm.   

BTW, do you have a friend named Al?

Thanks,

I don't have a friend named Al.

I strongly agree that the system must be exactly same tuned, like romero did with the magnets after the mechanical parts installed. Everything must be strongly joined, coils must be the same etc... I think you really have lot of work to do mondrasek.

Last thing is that I didn't understand your diagram at all. Which probe is for current or voltage?

Thank you.

Maybe i expect the voltage rise too much to be like in gotoluc's video here:

What are your thoughts?

Hi xenomorphlabs and all

I also have a video that demonstrates a resonating generator coil.

The video compares a high impedance coil (many turns of thin wire) compared to a low impedance coil (small amount of turns of heavy wire)

Link to video: http://www.youtube.com/watch?v=-GBS3sKcB8g

I tried to resonate the low impedance coil using capacitance from 1uf to 60uf but could not get it to resonate. Keep in mind that these were air core tests and I did not use a full wave bridge rectifier. So if you think I could of missed something I still have these coils and test box, so if anyone wants to recommend a test please feel free to post a circuit and instructions how you would like me to test it. Keep in mind that the Generator (8 magnet rotor) has a frequency of about 460Hz with the 3,000 RPM induction motor turning it

Thanks for sharing

Sorry that I did not specify:  Probe one was voltage, probe two was current.

Nice to have you aboard DW.

By the way I agree with itsu you should change probe1 and ground...

Cool, i had not seen that video before.
If you still have the apparatus, it would be maybe a nice test
to run in serial resonance and measure the voltage/current phase shift.
In series resonance there should be :

Therefore the series LC circuit, when connected in
series with a load, will act as a band-pass filter
having zero impedance at the resonant frequency of the LC circuit.

I have been trying to verify what Bolt has been suggesting
to create the condition for a power factor of zero with voltage
and current at 90 degrees phase shift by just using capacitors,
because it makes sense to me to as a possible explanation
for a negative entropy.

His suggestion:

Double coils can be made by winding up the two
electric wires to the magnetic core as a Bifilar
coil or as opposing dipole. It can be seen that the
dipole itself must be tuned to the resonance frequency
of the desired rpm * the number of passing magnets.
This is how Romero produced a self resonance coil by
hours and hours of tuning and clipping the wave
lengths without an additional tuning capacitor.
Remember Romero said "you can use capacitors its
another method and probably much easier!"

He looks at the resonant generator coil with transmission line perspective
where standing waves create an inhomogenous voltage and current distribution.

I think you are worrying too much about amps and watts. 
When the system is tuned it all be working in reactive power
the dump cap charge very fast to a higher voltage.
This is because the cap will charge on the pure voltage node
points from each generator coil while the current is
at the zero node so the cap is hit with standing wave.

Voltage over series cap into a short dc path and tuned is going to
be perhaps well over 50 volts. If you get non of this something is badly messed up.

I did not use bifilar generator coils, i am starting to think that
this is a must to prevent loading the motor.
Thrapps did use caps but his coils might be bifilar too.
