How bout this for a gap? A disk interrupted gap.

["Garry F." <garryfre-at-pacbell-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

I was reading the book from Brent Turner and as I was reading about the triode,
I had an idea. I don't think this idea is unique tho, I doubt that I am the
first to think about it.
 
Picture a gap, that had a non-conducting rotating disk with slots in between
the gap where the slots serve to allow a path for sparking and the spaces
between the slots serve to cut quench the gap where the slots arrive over the
electrodes just at the right time and the space quench the gap at the right
time.
 
This might be accomplished by adjusting the speed of the disk OR prescise
placement of the slots. Experimental disks could be cut from cardboard and
slots cut into the disks and a LED with a reciever could be used to test the
timing of the disk. Once the proper position of the slots is determined, the
actual disk could be cut accordingly.
 
I think it's an interesting idea, but I imagine it would be pretty tricky to
get the timing such that voltage would not soar too high before a slot arrived
at the gap.
 
Perhaps a safety gap would be indicated.
 
I don't have the knowledge or resources to build, or test such a thing yet but
maybe someone out there has already tried it or might want to try it.
 
It certainly would have the advantage of not having contacts that could fly off
the disk at high speed as in a regular rotory gap.
