There must be some kind of free cold discharge always present when local TC electrical field exceeds 28KV/cm ,but the problem appears to me that in some cases ,even in a complete dark, we cannot see any signs of such discharge around toroid. There is my beleif today that difference between 50 BPS and 100 BPS is more expressed than between 100 BPS and 300 BPS,and almost no difference between 1000 BPS and 300 BPS. Careful experiments must be made for final decison. --- > > Question improved E-Tesla program should answer > to: > > What max. toroid surface field corresponds to 400 > KV > > voltage on THOR secondary? > > Definately.

Growing of arc during TC operation is almost impossible to simulate.Even the moment of transition to stable leader state in case of TC is wraped in enigma. Personally,I have seen scoping of one particular coil's top current that has shown incredible chaos degree when discharged into air by thin wire put on top terminal. That's the why I give up in advance of any try to get deep into generalisation of TC arcs dynamics. Concentration to pre-disharging era of TC secondary stay my main interest (unusual to hear that from the mouth of spark junky) --- > If we can demonstrate agreement with large low-Fres > coils, > that would give a baseline from which to explore the > higher Fres regime. --- Experiments,experiments ,and only experiments .. -- > > Looks like we need to devise experiments to measure > the > breakout potentials from large(ish) coils with > smooth toroids > at low BPS and compare these with ET predictions. > --- Positive Regards, boris __________________________________________________ Do You Yahoo!?
