Just put one up. It's a just a quick "idea" sketch. It's built basically as
seen
here.
It's at  http://www.geocities-dot-com/capecanaveral/hangar/3108/squirlcage2.jpg

Opposite of the pipe ends, not on each side of the cage. Not really
different than
a standard gap RSG electrically. There are a lot of different ways to do
the same
thing.

Sort of. When a single pipe is closest to a pair of fixed electrodes.
However, the
fixed electrodes can be positioned in a few different ways. For example,
completely center when a pipe passes by or offset in a way that when the
spinning
pipes are leaving one fixed electrode it is just reaching another. Don't
really
know if this would be any different for an arc formation or quenching, but
it will
be fun to play with and find out.
