I'm also pro-small engines and boat engines.....

Ethanol is fuel. Use it right and it adds to the supply of homegrown energy. And any cost analysis that doesn’t take into account that fact that it doesn’t “disappear” once it’s been fermented, but that only the sugars have been largely used up would also take a barrel of oil and pretend it’s wise to throw away what remains when the amount of gasoline has been refined that can be refined.
All it takes for engines to be fine with it is the correct plastics.
