I think this article on the use of e85 fuel in a two-stroke outboard is pretty neat; I don't think there's a long term update by the author, but intriguing nonetheless.
What are all of your takes on using neat ethanol &/o e85 in a 2-stroke? In a 4-stroke? Especially insight on technical challenges, personal anecdotes, that time you ran a model t on moon-shine, etc.

Discussions on economic/environmental/political implications of ethanol vs. petro-gasoline are tangential to what I care about, so I've also created this thread so that anyone who really wants to speak to that aspect may easily do so.
