Where did you see these prices? I haven't seen such cheap E85 around here.
Mason City, IA The spread is such because there is no transport involved as the product is made locally.

A few other points:
Don't think you can run E85 in any vehicle. Before long you will be replacing rubber parts (hopefully before they rupture).
Never said you could or should. In fact I specified in an earlier post.

Although ethanol is higher octane, it doesn't mean it's higher energy, just that's it's less vulnerable to predetonation. Most engines designed to burn gasoline have a compression ratio of 8.5:1 to 12:1, a much higher ratio is designed to get the most out of ethanol, and that would make it incapable of burning gasoline. Who in the auto industry wants to invest in an engine that only burns a fuel that may not be here tomorrow? How many of you would buy such an engine?
Hydrogen is an even bigger waste of time and resources. Hydrogen is no more a fuel than car batteries are a fuel. H does not occur on its own anywhere on earth. Making it is a very energy intensive procedure and we're lucky to get 15% of that energy back at a car's wheels. We're better served putting that energy and research into batteries for electric cars where we can get 80% of that energy back at the wheels.
I brought up hydrogen as it is touted by some to become the ultimate fuel via fuel cells if I recall correctly. In any event, there are many possibilities out there. I will agree we have not tapped the depth of our collective ingenuity to supply our lives with energy for the future. While ethanol may not be long term, or perfect, it replaced MTBE as an additive, and does not need any modification to use.
