. . . a stand-alone grounded secondary [or more properly "resonator"] of the same Fres as the coil will even shoot some somewhat long sparks . . . If you are up to energy transmission . . .
I'm new to this forum. Are there previous discussions of Tesla's wireless energy transmission-reception system that I can look up in the archives?

Always remember air breaks down much easier at high frequency. for example, my 6kv 60hz NST has very little corona even when the leads are near each other. however, my homemade flyback with about 6kv out at well above audible frequency range, has breakout without any grounded source near it. Seeing that tesla coils are most often on the order of a few hundred khz, the voltage might be much lower than the spark length suggests. This is probably the same condition with the excitation of gases, such as neon and stuff like that.
Not too sure though, as i have done little experimenting with that kind of thing.
The reason for the flyback breaking out at 6KV is skin effect. At such high frequencies, the electricity tends to want to leave the core of the wire and get as far as possible away from it, which is why flybacks have such beefy insulation on the high-voltage leads. If it weren't for skin effect, many of the smaller (above 1MHz) TCs wouldn't even break out at all. Of course, the skin effect does lend some to the spark length, but not as much as people seem to be giving it credit.

hehe nope, the skin effect only redistributes the currents flowing inside the conductor. The RF disharge is easier to break down because of the higher electron energy, while it's easier to sustain as the spark's own capacitance now plays a role. Also the capacitive coupling is the reason to make a thick insulation.
