ENERGY AMPLIFICATION

Try to use higher DC voltage level in the caps like 15 - 20V or maybe 30 and so on.  Also try to do the test I suggested to totoalas above like collecting the voltage spike of the collapsing flux of L1 in C2, when S1 is just switched off, see the schematic in red rectangle.

Ok i will try that...

there is a problem with relays- spark or arc is formed...remember what Tesla said about spark gap looses and why he invented quenched various types
I know why we have so much problems - Tesla routed into HV but also large power to compensate looses...we cannot, right ?
all you need to do is ring the bell and bell rings TWICE and you have to catch second ring or echo ring
that's all
unfortunately I'm struggle with electronics to allow all conditions...very slow progress.....no working device yet 

Relay contacts  tend to stick when arc is too strong    How to catch second ring? If first ring should not  be affected? Correct Timing?

By pulsing the arcs   maybe will solve the problem...on time   off time   i tried to look for the lawson circuit used in hho and see what can be done
theres another circuit   aviso  konehead circuit that deals with this
happy weekend

Hi,
I totally agree with you that a controlled ON time will make Mosfets favourites in this application but that is not all to be considered. Must use multiple mosfets in parallel to get close to the sharp ON/OFF time that thyristors are handling very easy. My suggestions are based on my experiments with higher voltage where before switching to thyristors I have burnet so many mosfets and IGBT's and the results now are almost comparable to a spark gap. In my experiments I found that a very sharp complete discharge of a capacitor is the real deal, I never care about what books are saying, I always try to see with my own eyes.
The best way to test and calculate coil and the capacitor to be used in this experiment is to just use 2 mechanical switches. Charge cap 1 then discharge it and watch voltage in the second cap. Do that slowly repeating and making notes of what you changed. It might look very basic but that helped me many times. 
Anyone considered using a different type of conductor? not just ordinary copper?
Anyone tried doped conductors? if not please do, you will see a big difference.
Regards,
Romero

good progress 


that's why Tesla choosen high voltage - silly that took verpies so long to catch


tell me : how can you ring rubber bell ?
