Oh my God that flame is beautiful! Im stunned...
Anyway, i have only done it with vacuum tubes, but i have gotten a flame no lower than 10MHz, with smoothed supply, and no topload. I really wish i knew more about the pic that you just posted! Have any more info?
Anyway, Richie Burnett AKA Geordieboy is the only person i have seen make a solid date coil with a flame, and his ran 4MHz (at least the thouroughly documented one), though his was not a flame like a lighter. It was crazier and what i would describe as 'hectic'. Search plasma tweeter for more arcs like this, though most are smaller and with tubes. My favorite video of one is this: Very efficient, the tube is only 40w dissipation. Also here is mine: The flame is not straight up as it is halfwave rectified.

That is where I found the picture. I've seen the 4mhz coil before, pretty cool stuff
Oh, ok, that is a ground arc, not simply breakout. That happens at any frequency with a sstc when you draw an arc so long as it has high enough on time, especially CW.
When you say ground arc, do you mean to a grounding rod that is being pulled away from the toroid, drawing the arc length further away from its origin? How does cw affect this? Thanks!

Yes, that is what i mean. CW would make it thicker and more stable, it looks roughly like a flyback arc at relatively high power.
If you used a flyback on a sgtc in place of the NST, would you get similar effects to flames as breakouts from a toroid, or would the breakouts look the same as a NST style coil? Does frequency come in to play to alter the flyback's breakout appearance?
