My own work here suggests exactly what you are saying. There appears to be
an optimum power curve for any given system beyond which more power just
heats the air. Also sparks in the 30' plus class demand tremendous
expenditures of power to grow even another foot. A completely different
class of systems seems to be required to work beyond 20-30KW. What
embodiment these may take on is beyond by ability to crank out hardware.
Other than for Greg Leyh's system, most in this class which I have seen were
abysmal performers. (based solely on personal surmises and extrapolations)
