There are many problem with running even 10% ethanol in many aircraft, so how many people are planing to factor this into their current project? once your aircraft can run on the stuff without problems, where are you going to fill up?
I see so many benefits to this fuel, the biggest "wow that is cool" is that stuff that grows along the side of/or makes up your airstrip. grass. sit down with mates, have a think tank and build a still to make moon-shine to power your engine.
I watched a show a few years back on this old guy in Brazil, he was a crop dusting business operator who for the past 10 years had been running his planes on 100% ethanol that he got for free off his sugar cane growing friends he worked for without the slightest problem to his engines, due to the fact that the aircraft were set up correctly.
What are your thoughts, remembering that we are talking about an aircraft that will run on 100% ethanol with out ANY problems............
