I imagine NO.

Not an expert but the whole premise of these systems is to maintain the 
arc, not extinguish it as we desire for TC use.

This was a clear lesson on one of my earlier static gaps.  I used dome nuts 
on the end of brass rod and some lengths of copper pipe for heat 
dissipation.  The dome nuts formed hollows in the ends which trapped 
heated/ionized gas and the subsequent performance was ABYSMAL !

I would imagine these hollow rods would suffer exactly the same problem 
....... unless you forced high pressure air down the middle ..... HMMMM ???

Cheers

Mark
