Fr. McGahee,

You have just described _exactly_ the concept I came up with about two 
years ago which I dubbed the 'Stephens Coaxial Magnifier'.  I and 
Malcolm Watts discussed it quite some time ago off-list.

I think it represents a terrific fine tuning of the basic classical Tesla coil 
engineering/design.

Now that the cat's out of the bag, do I just imagine or actually 
hear  the word  'Contest'?  : )
