What if capacitor discharge and coil discharge can meet in space ? or rather what if we arrange frequency of discharge of capacitor , coil disconnection , length of coil wire ,then attach antenna to coil in such way that capacitor discharge (which is creating current) will meet voltage spike in antenna then both immediately will diminish....

Hey Forest
before I started playing with this circuit, I thought I had an idea of what is going on in this circuit from the beginning to the end of the cycle of events, and more or less the description of the circuit. But things are not quite as they are presented I feel. Not in a bad way, but some info must be missing, cuz I think Tesla would know exactly what I am thinking, but the pat doesnt say it.

Just as in the sim circuit, every time you hit the switch and release, you get a different output, every time. So when we close the switch, the cap and inductor are at different levels of charge at any time.
Now, unless the large inductor and cap are very large as that they have a resonant freq that is so low, that by the time the contactor is ready to spark the piston, literally, that the cap has just reached full charge at that point in time, or maybe just in the range of full charge.
So Im working on a sim circuit to try and sim the situation I just described to see if I can get that timing just right each cycle and see what we see.

No!, its not fake, if it is a fake we can make it run, the inductors has primary and secondary, the primary has the transistor to amplify and make a discharge action in the core and that makes an electromagnet and it add torque of push and attract ok, and the two secondaries made in series charges the capacitor and power up the fan and contribute to the rotation!. and by adding some tail it makes it more really powerfull cause a strong collapse of magnetic field is strong that produces a strong electromagnet.

;D

Yes,it's not fake as you described it Tito, but Mags touched most important aspect : synchronization.Without proper synchronization there is no significant output and Tesla even patented various method of adjusting his igniter circuit.The problem is in oscillator initial stage : let assume it is MOSFET driven and MOSFET is managed by kind of circuit - it all depends if it runs on ON or OFF state at start and what it means to the ignition circuit. You can have coil shorted or capacitor charging.The best method seems to have first coil shorted , then coil collapse charges capacitor while additionally power source also does this.
The second aspect Tesla mentioned in interview : it's of tremendous advantage to break at peak of wave.

Hey Guys

I will be moving this week so I wont be much on the net till im done.

I did some playing with the igniter on the sim and if the large inductor is very large, the time it takes to charge between sparks seems long enough for the cap and inductor not to go into oscillation between sparks.
And all that would depend on the engine involved and its rpms/spark timing.
So in a modern spark coil, and considering the multiple cylinders and high rpms achieved, the primary of a spark coil would not be connected to power very long anyway. And in newer vehicles, individual coils are used and the on time would be longer for each compared to 1 and a distributor.
But without values on the large inductor and cap as per teslas original idea, it is hard to say what was really happening for sure, and he says that the values can be changed for a particular use.

Will touch base within the week.
