hi scott and all
ok full contact spark gap that sounds like it might work if your
dealing with low power but as power increases so does the wear on
your very small piece of bridging electrode i dare say it would
desintegrate quite quickly or simply overheat and damage or warp the
disc plus a solid state device whatever the size would be about a
million times smaller ,tesla mentioned a mercry break this also was
supposed to be a sparkless gap ive thought and thought about this
thing and i dare say others have too the words "holy"and "grail"jump
to mind so go for it anything thats even close to working will turn
you godlike lol
regards
earl
but then again i have no idea what im talking about!!

Hi everybody.
Since everybody is talking about spark gaps, I figured I'd
throw out an idea I've had rolling around in my head for a
while. A spark gap has losses in the spark, but solid state
cannot handle the raw power a spark can (not yet anyway), so what
if we eliminate the losses by having direct contact, and eliminate
the power issue by dumping the semiconductors? Here is my idea,
take a rotary spark gap, and cut the disk mounted electrodes flush
with the disk surface, then mount brass bushings between two
shafts, pinching the disk between them. As the disk turns it will
make contact with the bushings and complete the tank circuit,
dumping loads of power into the primary. The obvious problem with
this is it will arc before it rolls over the contact defeating the
whole purpose, but my thinking is you could use a smaller rod to
increase "quenching" and submerge the whole thing in mineral oil
to keep stuff cool and cut down on spark, but you will need a
really tough motor. Has anybody out there tried this already?
would there be any benefit? would it be as difficult to build as I
think it would be? Just curious, thank you much.
Scott Bogard.
