	Extremely interesting comment-- and I think I see the conundrum-- 
it is a version of the usual butterfly-in-Bermuda banter, the effects of 
changing one aspect of a system may vastly alter the system itself and 
all of its assumed parameters, so that the resulting effect may not 
correspond just to the adjustment, but to all of the things it affects.  
	This breaks down commonly held assumptions about the 
"separateness" of abstract terms which we may apply to the Tesla coil, 
and also any sense that there is a "theory" behind the event which may 
explain it completely.  Am I in the ballpark?  Agree, disagree?
