Oops, after a better look at the photo it seems the plasma _does_ extend beyond the inner electrode, at least in this "star mode", so I'll retreat to my previous argument, namely that the metal grid is there for a reason (maybe only to initiate the plasma BTW), and that it could be advantageous to replace it by something less substantial. No?

(was Re: Chlorine photo-reactivity) Besides, it seems the central plasma doesn't extend as far as the inner electrode in fact, see the photo here: http://en.wikipedia.org/wiki/Fusor#Basic_fusion This eliminates the already conducting gas argument I guess. Other objections welcome ;) Michel ----- Original Message ----- From: "Michel Jullian" <[EMAIL PROTECTED]> To: <vortex-l@eskimo.com> Sent: Sunday, May 25, 2008 12:23 AM Subject: [Vo]:Re: Virtual inner electrode Fusor? (was Re: Chlorine photo-reactivity) Or it could be viewed as a thin plasma that is already conducting as you say, in which to create an even more conducting path... This is what the solid metal electrode does I guess, it must be there for a good reason! The idea would be to replace it by something more insubstantial, which doesn't intercept the particles...

The problem with this is that you are assuming a neutral gas in which to create a conducting path, whereas what you really have is a container with a thin plasma that is already conducting. >This might have some potential (pun intended) since collisions with the inner >grid, whether of ions when it is negative, or of electrons when it is >positive, seem indeed to be the limiting factor when that grid is solid.
