A friend asked me to post this:

He's designing a coil that might have up to 30 Kw input on the primary (!).

Would there be a practical differance in performance in going from 3/4"
to 1" copper tube ?

The price is about double for the 1", which is why he's asking.

C = Pi * Dia, so I'd say that resistance would go down by 25%...

Given the losses in a standard sparkgap, I'd guess that you wouldn't 
see too much differance.

What does the collective wisdom say about this ?
