Re: [TCML] Pig based coil design.

Gary -

Two questions:

1.  You stated: "The variac tunes the spark gap to the exact speed to get 
maximum output."
    By "exact speed" you mean airflow rate, correct? There is no rotary 
spark gap, and the only variable is the amount of air passing throiugh the 
static spark gap?

2. By "12 foot arcs", you mean single arc channel or streamer, from topload 
to some other object, and not two simultaneous six-foot arcs from each side 
of your topload? In your photo, it looks like the coil is generating two 
simultaneous 5-6 foot arcs from each side of the spherical topload.
