Re: [TCML] 5" Sparks - Approx 35 watts input power: Tesla was correct!

Peter, Jeff,
I agree with what Peter says below.  Also I don't understand why  anyone
would consider it difficult to produce a 6" spark using 35 watts even  for a 
type of tesla coil (non-kicker type).  Using my formula:
  spark length inches = 1.7* sqrt input watts (wallplug)
gives a result of 10" for 35 watts.  However small coils seem to give  shorter
sparks than the formula suggests, so perhaps the spark would be about 
6" or 7" long.
