James,

If you were to "compare" coils built by Tesla vs our coils today, you will 
be hard pressed to find anything to compare by. Tesla built high frequency 
coils for experimental purposes and sparks were a byproduct (which he spent 
long hours to prevent). But, as Tesla was human, I'm sure he liked sparking 
his coils just like we do. Our coils today are more efficient in materials 
and design (for producing spark lengths at a given input power). There's no 
question about this. Check the archives if you get a chance. There is 
information there regarding some of his coils efficiency, etc.., as this 
topic has come up several times in the past.

Here is an arbitrary example of input watts vs spark length (assume average 
length random air sparks):
Coiler today: 10,000W = 14 feet (your mileage may vary)
Tesla:  10,000 W = 10 feet (his mileage varied too)
Tesla or coiler today: 100,000 W = pretty pictures regardless of efficiency 
to make people go "ooh  aah".

Difference = materials, knowledge of losses, lots of trial and error 
experience with what works and what doesn't, and the simple fact that we 
like making sparks and we like examining the dynamics in the electrical 
behavior of a Tesla Coil. All this leads to better coils (for sparking). 
Tomorrow's coils will outperform today's.

It's not just a hobby, it's an addiction <grin>.

Take care,
Bart
