Great to hear there is work going on to unleash the efficiency potential of methanol.

Well if we are talking a regular production engines on E85, vs optimised designs running on methanol which at present are out of reach with very high compression ratios that will also run regular gas, if the engine is running closed loop, at 9.8:1 we are talking 45% more liquid than gasoline at 14.7:1. Yes or no? Approximately that is, give or take a few points of specific gravity differences. Maybe my math is wrong.

That said, appreciate your insight into how "reversibility" of the combustion process is applicable to a current and regular production engine. Isnt that getting in to a little Alchemy?
