Jack,

No!  I'm just saying that it is DIFFERENT!  I have always maintained that 
smaller systems are much more efficient than larger ones, but only so far 
as spark is concerned per watt of energy.   Spark length has no linear 
linkage to energy or power conversion of efficiency!  There are three or 
more characteristic outputs which can be used to determine efficiency of 
a Tesla coil!  It could be looked at in terms of spark length output 
(show and flash), a space heater, an RF generator,  an Ozone engine, etc.

Different systems in different configurations at different power levels 
will be more or less efficient in the above outputs.  The output 
efficiency in any one area will rarely smoothly track the input power 
even with a fixed design configuration!
