Ernest, George,

Good posts.  As for an alternative, I think I may have mentioned the possibilities of butanol as a replacement.  It has nearly the same octane, and nearly the same amount of energy per gallon.  One fellow  I've met is making butanol out of bio-waste and wanted me to test it  in my rotary.  Not on my first flight!  But, it is supposed to be a  potential alternative.

Best Regards,

Steve Thomas

Ernest,
All too true, however I can't help feel we are on a  transitional  path to somewhere, as yet, still unknown, in terms of future fuel  use. I won't go into the vagaries, but lets hope it pans out, maybe  there will be a range of credible cost effective alternatives. I  just wish I knew what the end game will be.
