ENERGY AMPLIFICATION

[forest]

why there is capacitor on feedback loop ?

I do not state I understand this circuit nor that it won't work
just for me a few elements are missing or misplaced, well maybe 2

Do you think that this other energy amplification circuit is wrong too?

This shown Diagramm  (BDX87 Darlington Transistor) is an very know, and usually shematic
that can uses as inverter.
Low voltages to any higher (or lower) voltages.

work on higher frequencies (usually 5000 to 20.000 Hertz  - in relation zo Cap and inductor/transformer CORE-material)
But in any way, no amplification the Power.

Only voltage can amplify (current go down.
Or transform the Voltages lower with higher currents.

In any Way the volt time amperes  = watt (power)


this exeed never the need input power to drive this.

Normal way about 90% effency

P.S.

Do not buy this Darlington Transistor. : use
2 normal transitors  and 2N3055 and Tip 31 (Bd241) instead

Thank you @pese

first one looks nice,not perfect just nice

questions:

is zener diode in good position ?
what is triggering zener diode ?

You must test if it let the voltage through on this position, without reaching its activation voltage. If it does, switch it the other way and retest. 
A voltage that is less than its activation voltage should be blocked.

It supposed to be triggered by the rising voltage on the secondary coil that fills the cap to its capacity.

I must say here that I am just learning.

I thought that it was needed there to protect the diode and the battery from the spark intensity.

I liked Nieves circuit, but the zener was in the wrong direction. I have not tuned it in the least, just got it done.
But the zener does do the deed, at 480v threshold.
I will play more with this tonight.  But I wanted to share. =]

Ok   took a bit of time, but here is something that looks good.
