Hmm, this was really well written, I'm quite surprised that i read it to the end because of my very low attention span. I had actually come across the idea of using alcohol as fuel particularly in Brazil as you mentioned.
I remember wondering why its adoption wasn't already widespread, but you pointed out that already. I would like to know, what's the cost of buying a litre of the ethanol based fuel compared to buying the regular fuel?
