You may try out transmission like theory based calculations. Too
lossy system will not
put out a lot of voltage according to calculations done like
described in "Vacuum tube
Tesla coils".
I guess Bylan is making an assumption that power is dissipated in
corona immediately
or something as absurd. The power in a solid state coil with a top
capasitance is actually
circulated in the coil for a while before the breakdown occurs, I
think.
Anyway, I'll not take what Bylan says granted. His design was so
poor, he suggested
an optinum system being a huge coil made of thin wire with almost no
top load etc.
I guess that's the only way that poor system did not break down. He
was happy to see
the system used for several minutes per run! I think his article in
Radio Electronics is
mostly crap and erratic as usual for Dylan's designs published in
that paper.
