Since this talk about multi-static gaps has been propagating on
this listserv, I've been wondering about the feasibility of such a gap,
carried to the Nth degree, on a hi-power coil. Like ten or twenty gaps
divided equally, made with big pieces of material acting as big heat sinks,
and lots of airflow with a big fan.
You see, I fear I am destined to have to build a RSG, and am actually
seeking parts to do so. However, as long as it is possible, I'm going to
continue to delude myself into believing it's possible to consider alternatives.
(for my about 10,000 watt, 27,000v, 16-20inch coil).
Yeah, I know - I'm nuts ;-o
