I agree with you, Denny; they're missing the point, I think. Do you remember the Fish/Kendig VV carb, back in the late fifties/early sixties? It was proven to be very effective, and in so being, threatened the profitability of the oil companies - it more or less vanished, as did it's inventors; and so it has gone with anything that threatens the moneymaking power of a select group in this world. To all of you who scoff, I suggest that you google "Suppressed Technologies"; some interesting and alarming stuff, there. Or, perhaps, invent some remarkably efficient and highly technologically advanced fuel or energy saving device that would seriously change the status quo, and see what happens - got the guts? I don't.
