Russ,

Back in the earlier days of RADAR, various styles of rotary spark gaps
were designed, and this approach was tried. It didn't work very well  -
the very hot plasma tended to rapidly erode the insulating material.
Glasoe covers this technique a bit in "Pulse Generators", McGraw-Hill,
1948. I'm not aware of any modern day coilers trying this however...
