        I greatly admire your sense of charity.  It may exceed your
        technical acumen to some degree (or it may not) -- but I do
        admire it.

        It seems to be stretching physics to rather severe degree
        to declare a glow discharge and an arc to be one and the
        same.

        The reason an arc is so-called is because of the shape it
        assumes (it's from the same Latin root as arch).  Although
        we Tesla-ers sometimes describe our discharges as "arcs",
        the strict definition requires the discharge to take place
        between incandescent electrodes.

                Being humorous?  Oh?  And like I wasn't?  (Already I'm
                insulted   [ doesn't take much does it? ] ).

                Six-ft. discharge from a 900-watt neon transformer?

                Sounds like Guiness Book of Record stuff to me.

                That's 72-inches, son.   I think most of us will
                believe that when we see it - along with that
                200-ft. (or whatever) coil which went to that
                mysterious (unnamed) Pacific island.
