I have a question

Has any body thought about building a center taping coil. Like a multi taping transformer?

we are all worried about what to the coil resistance should be verses the  Inductance.

sorry more mistakes in last post I wrote this:

"Actually I made mistake, you wont be losing 1/2 the power (voltage in cap without load actually not so much power), as Stefan mentions, since the collector cap wont be at "zero volts", it will be at the voltage that the generator coils fill it up to during the time period between pulsing the collector cap to run cap...and this time period can be variable to fit the performance of the genrator coils output and the draw of the motor"

what I meant to say is that the RUN CAP will not be at 0 voltage, which collector cap dumps into....the run cap will be at the "voltage dropped"-level of whatever the motor coils will drain it to, during the time-period between pulses...

I was going to post about Stephan's reply, but I just realized that you made the corrections.

So, to recap, if you have 2 equal capacitors, one fully charged and one discharged, when you connect both together, you end up with 2 half-charged capacitors. There has not been any loss of of energy in the conversion. You can then recharge the first (collector) cap with half the energy, as it is already half-charged. To be able to charge the Run capacitor to (almost) full voltage of the Collector cap, the collector cap would need to be much larger than the Run cap.

I hesitate between two schemes to drive the coils:
1-  This one we're talking about where a capacitor is discharged into the drive coil.
2-  The "standard" direct voltage drive where a transistor switches the supply into the coil.  The advantage I see here is that we can recuperate the back-EMF pulse at the end of the drive duration. According to Joseph Newman, the back-EMF pulse contains TWICE the energy that was used to magnetize the coil in the first place. So wouldn't it be better to try to drive with very short pulses that just magnetize the coil to (almost) saturation, and then immediately recuperate the spent energy ?  I think he said that the more copper there was in the coil, the more effective this technique was.

Thanks for your comments,

I just found this interesting site that examines the effects of adding a magnet on top of a core & coil. Nice graphics.

This is wrong!

You have then actually lost half of the energy  !!!

Very important error!

Oh right !
Forgot about the voltage.
Then, this makes me think about a way to gain energy by combining capacitors together...
