Here is something for you Kapanadze/Don Smith guys:
This circuit uses a car ignitioncoil wired backwards.
It runs the HV winding in series resonance from a 6V AC wallwart at 50Hz resonance (the line frequency in Europe).
At resonance, even though the voltage feed to the circuit is only 6V, the voltage drop over the capacitor and coil is about 5-6KV so the CFL-tube lights up.
The reason for the CFL is that without it the capacitor blows up.
What is even more interesting is that there is 5KV over the HV-winding and stepped down by about 85:1, there is low voltage AC output on the primary winding with a stepped up current.
For 60Hz line freq the capacitor needs to be changed.
Now go figure
Many Thanks for the idea. Looks very interesting and promising. I will try this soon.
Many warm regards
Hi T1000, Don't you mean to say the input frequency is 1/4 the resonant
frequency of the secondary ? The primary coil should be tuned to resonate at
the same frequency as the secondary coil. The input discharge frequency can
be a fraction of the resonating frequency, I find 1/3 to the best fraction.
Hi, the primary has 4 lesser frequency than secondary natural resonance which gives 90 degrees wave aligment with maximum potential difference.
When you get equal mass of primary and secondary it will get aligment in means of mechanical oscillations with connected swing: Electrical Resonant Pendulum - YouTube Also Tesla coil should be looked from mechanical point of view and the capacitor plate on top is the "condenser" for imaginable liquid gas. This is where N. Tesla was coming from - http://www.free-energy.ws/pdf/self_acting_engine.pdf

Can you demonstrate that ? So you are saying that with a secondary coil 1/4 wl resonant at 100 kHz the primary should be 1/4 wl resonant at 25 kHz ?
I disagree, I would like to see that shown, done with a function generator and
compared to both resonant at the same frequency.

My team done with 1/4 frequency on resonator half year ago as I calculated everything by wire length ratio 1:4. Also Tesla coil was immersed fully in transformer oil and it kept running with flickering CFL on top for some time after power was disconnected. Unfortunately we did not made YouTube video but some private videos are there.
What if i put 50 khz same voltage instead of 60 hz?

i really like ignition coils, but as mentioned, they saturate at very low khz. but, like my last few vids, you can make a resonant primary LC for the inductance of your ignition coil primary, and the 60 or 50hz freq from the inverter
In the beginner's mind, there are many possibilities.
In the expert's mind there are few.

you are awesome man, thanks for your participation here
