Overunity Parametric Oscillator?

[giantkiller]

Varying the inductance is what the tpu, ismael, magnacoaster, Kunel, bearden MEG, DUAL PULSE PROTOCOL, T-Kapanadze, shorting coil at peaks, and joule thief do. There is also the action of utilizing bemf looped back.
There are numerous examples. Alot of my youtube vids are comprised of using this process. I am not claiming ownership, just validating any other efforts.
Always look at the time frame of variance of inductance to identify the device configuration.
Loopback is the other parameter. Some happen in the core, wiring or external circuit. The gk4 by Otto's configuration looped the controls into the collectors. The collector bias can be shut off or squeezed( by Steven Mark's terms).
There is nothing magical about this. Obfuscation, confusion or made up terms to get this across should have never been used. It is this simple. The proof is all over the place.
Safety has always been primary concern. The cataclismic events can be easily attained. The control is the primary goal.
May we all go down in history...

Shorting the inductor would change its resistance, thereby altering the current.  Naudin's writes that the parametric-effect is a result of the change in inductance (dL/dt), not current (di/dt) and where the magic lies - at least that's my reading of it!  What pisses me off about Naudin is that his website is full of mouth-watering stuff like this, followed by a "more to come..." statement, but it never does - that parametric posting is from '97 and was never followed up! 

One of those magnetic-amplifier chokes in place of the inductor might be a better way to go.

Lets kick this up a notch.
I see your 1 and raise 100.

Got this off the factory floor.
