Richard,

You are right about Tesla's ideas, and polyphase power is the way to go 
if you must get the most out of AC. You could actually build or purchse a 
modest 3 phase MG set which would run off a 220 volt single phase motor! 
 The alternator need be the oly three phase item.  I have though of this 
as a very doable stunt and the only way to get quiet 3 phase power in a 
residential neighborhood.

Before I would do this though, I would go to DC power. 100% available 
power 100% of the time, regardless of gap conciderations!  This is the 
number one best power for any Tesla coil system!!!  It would take a bit 
of doing in rectifing and filtering the HV to produce real power.  Greg 
Leyh did it in his system and it works nicely.

Whatever the future holds, keep us informed about your "next step up"!  
Good luck with the 50 KVA power plant!
