Ghazanfar Ali Generator - Utlilizing trapped energy

[JJUK]

Like .99, I'm looking forward to seeing the video that Ghazanfar has promised us on return from his offsite operations. When can we expect that Ghazanfar? I think we're pretty close to 3 weeks now.

At the point when I am out of the resonant pulse, there will be a large increase of 4700uF dissipation due to decrees of
LC resistance and not only that but this will immediately destroy parallel LC oscillation and result in FET overload.

Hi Dole, 

These 3 things: detuning the LC tank from the real input frequency and the increase of the current taken from the 4700uF and possible FET overload are connected to one thing: the much lower LC tank reactance away from its resonance and you surely know this, I mention just to emphasize. The resonant voltage across the LC tank cannot develop when either the input frequency does not match the LC's resonant frequency or the LC tank circuit is not tuned to the input frequency: in both cases the LC tank is not a 'tank' and has low reactance, this means it can pass high current.

Theoretically at the resonance LC resistance = infinite, but I was never able to get there.
Finally mixing this with nonlinear R (load) in the series LCR seems not so easy to achieve!?

So it must be some way to self-tune to this nonlinear oscillation (Gyula ?) because we are in the real world and not in an ideal simulation.

But with hard work.. maybe
d.

I think we can rightly forget about the theoretical LC behaviour when we build such circuits, we are in the real world indeed with lossy components, no wonder you cannot find huge resonant voltage across the LC tank if this is what you mean. 
The bulbs are indeed nonlinear loads and when they are cold at first switch-on, they have much less resistance of course, behaving as a 'more severe', a heavier load, then their resistance increases as the current heats them up (if enough current is available).
It would be good to know whether the nonlinear load behaviour is needed for this circuit or a constant load (like a high wattage 150 Ohm linear resistor) would just be also fine.  Further considerations could surely be made on what you call 'self-tune to the nonlinear oscillations'  but this is too early as yet I think.  IF you do not have a scope to see the waveforms as shown in the simulation, then all what you can do to be sure you have the LC tank in resonance is using an LC meter and tweak the values as Ali described earlier (a 18uF capacitor is not easy to find, you may have to assemble it from several pieces in parallel,  and your some mH coil is way too high with respect to Ali's uH (347-367) value,  though it might work with mH coil too, who knows...

poynt,

Forest referred to my last post where I wrote to dole that it was not easy to find a 18uF capacitor and could be assembled from several pieces. 

4 times 4.7 gives  18.8uF,  close enough.
