Back in the dark ages, induction coils were used to feed Tesla Coils the way 
NSTs are now.  It's a good way to run a TC from a car battery. Check out the 
info on 
<http://freeweb.pdq-dot-net/headstrong/ind1.htm>  He covers step-by-step 
instructions for reproducing early 1900's induction coils, Tesla coils, 
etc.etc.
