Tew kewl ;-)  I read a while back about someone claiming 3 foot sparks from
dual- ignition coils. Can someone search the archive & find it? Would be
nice to have a decent boolean search engine on the Tesla List's web page.
Otherwise, when I get a 10 Gig disk I'll go through the agony of snatching
the whole archive so I can search it effectively on my own PC.

Great!, but isn't voltage typicaly 50KV/inch?

But how much energy/bang & average power?

Thanks...

1/4 Joule 10/second is 4 watts average

How else do you know what its good for :-)

See my "ignition coil measurements" post for my ignition coil measurements.
