Hi Dave,

If your assumptions were the mechanics of the vortex I have witnessed, then
there would be a vortex under many different conditions.  I can only
generate the vortex with specific conditions.  Yesterday I operated the
plasma ball at a much higher energy state than I had at the time when I
observed the vortex.  There were long streamers in the globe, it was solid
red in color, and sparks jumped from the globe to a fluorescent tube across
1 1/2 inches of air, but there was no vortex.

I'll certainly be investigating the vortex in greater depth later.  My
current view, though, is that it was caused from electrostatics and not from
fluid or plasma convection.

Dave

	The usual discharge, especially in a plasma globe is particles.
	Ions.  Electrified atoms.  They follow the usual laws of
	convection, with flows affected by (among other things)
	heat.

> We're talking about EM.

	EM excites a plasma.  The plasma, composed of particles
	is influenced by, among other things, heat.

	Nor in large, unenclosed ones.

	electrical discharges routinely follow air movements, or
	those of other gases/particles.  cf any text on lighting.

	The globe has a 'large' surface area, and the heat flows to
	the entire surface.  Any one point will heat minimally.
	And the actual power levels are small.
	And much of the power goes into maintaining the effect inside
	the globe.
