Summary: I built one but never got as good effects

I built a Tesla Coil when I was in High School in the early 70's.  I used the
popular electronics "big-tc" plans but for some reason I never got the kind
of effects you people have described.  My system used about 5 feet of carpet
tubing for the secondary (heavy laquered cardboard about 4-5" around).  There
were 3 glass plate capacitors about 1.5 feet square wired in parallel, a spark
gap and primary with about 10-12 turns of heavy wire.  The primary was driven
by a 12kv neon sign transformer.  The best I ever got out of it was a 6-8
inch discharge (to a nail on a broomstick).  Did I do something wrong or is
my coil too small?

Regarding weapons...I heard something bantered about on CNN awhile back about
generating "cold implosions" by projecting "scalers".  The equipment was 
supposed to be based on some of Tesla's work.  Any idea what they are talking
about.
