Well stated! Again, the air arc/ion dynamics are what makeo or break the
sparks. An engine that plays to this audience will win the spark race every
time over the electrical theory for optimum terminal voltage or base current
at the source engine.
Also the shepherding of the strike environment about the system will improve
spark length, too. I think that if a coil were isolated such that it stood
10 times its resonantor length as a radius for a sphere from ground or any
ground object, (within megohms of grounded), then theory of the engine might
fair better. As it is, their are almost always things to bleed corona at
ranges far beyond the theoretical strike range. The ion/air/arc dynamics
then takes over and longer arcs prevail. They can be made longer still by
moving such objects farther away and playing with the ion lifetime/versus
break rate to reach out a bit farther. Thus the voltage out might be the
same or less, but more average power fed in over shorter time periods favor
ion formation and rejuvernation along formed channels. Thus, a smaller cap
fired at high break rate asynchronously might give the same average power
through-put as a big cap poped optimully by a sync gap, yet strike a good
deal farther out. This has certainly been my finding over these many years.
