Im curious as to why the VTTC has very little to put out as noise 
pollution.  Both of my VTTCs simply make a 60hz tone with some hissing 
noises, but quiet for the most part.  Of course when the coils get bigger, 
that sound get a little more intimidating!  So what are the physics behind 
this?  The arcs have more current and look thicker but make less noise.

Also, what makes the arcs from VTTCs and some SSTCs to have a straight 
thorny look to them?

These are just the questions that many asked at the Teslathon, that i had 
no idea about how to answer.

PS, just to clear things up, are VTTCs continuous wave(CW)??
