I am trying to make these too.  I only have 900W right now but I have a
2500W 400kHz supply at work that should run off my home voltages.  This
looks too cool not to play with :-))

"I" think it is a piece of real ball lightning.  I think you are seeing
nitrogen being burned in oxygen to form NOx compounds as told in the paper at:

I think you also need to get a swirling vortex thing going.  Sort of like a
smoke ring or tornado.  That will feed the flame and keep it going.  Some
of the Russians have worked a lot on the air current part of it.  This is
probably really hard to get going.

Then it appears that you need some extra chemicals like water, dirt, wood,
carbon, etc. to help it burn.

So with all three parts mixed together, one may indeed get this ball
lightning stuff going.  Your tests are a vital piece to such a theory.

If you are "burning" air, that is a big start!

Cool!  This is sort of what I was expecting with more power.

But it is as close as we seem to get.  I think ball lightning is right in
our hands now but we just don't "see" it or tickle it just right to get it
going.  I think the "answer" is right here waiting for us :-))

I will post your new info to the Tesla list too.  Maybe someone else will
manage to figure it all out and save us the work :-)))

Cheers,
