I'm not sure as I really don't know enough. http://www.overunity.com/12590/thane-heins-rodin-pulse-motor/#.UzEU8a2Szoh that's where it was concluded I was dreaming. I did do some meter tests and when I measure the current draw coming from the gen coil to the battery it was only 80mA Still gave me a helluva belt though at 1kv though when I wasn't connected to the battery.

Jimboot is correct. Coil current creates magnetic field that opposes the magnetic field created by moving magnet. Ideal case being 90' phase shift, 100% cancellation and zero net magnetic field in the core. Lenz's law it's called... Best way to investigate this effect is shorting the coil and sensing core field with ratiometric Hall. No free lunches there. Any external load will reduce phase shift, remove cancellation effect and require input from prime mover.
Sort of special case being coil with conductive core (that mimics shorted extra winding having series resistance).
Current in main winding will shield the core and remove energy loss created by "virtual winding".
But that's just replacing "useless loss" with "useful loss". Both will appear as load on prime mover.
So if the setup will not draw less than with coil/core physically not present in the system it's time for reality check...

Well thanks... I've just done some mistakes and learned from them

I have question about your work with TH. Do these special high self-capacitance coils ever reduce input draw to level *below* coil/core not physically present?

No, not at this time. This is what I'm trying to fine tune and what you believe not to be possible to do.

Not in my experience. Not sure about TH work itself.
