	Sure.  Its called an SSTC, or one of the huge number of
	variants.

	Suggest checking the archives under gap losses, or similar
	subjects.  By all means rediscuss, however much discussion
	has taken place.

	Bottom Line (so far) seems to be that for sheer power handling,
	cost, and robustness, a good spark gap is hard to beat.

	OTHER approaches also have losses. 

	By all means, there may be something to find, however it has
	been discussed.
