Kenny: Well put! If D-20, or similar, was non corrosive to our existing pipelines and storage tanks, and distribution would not be a problem, and we could have something REALLY BIG. I noticed from the Wiki link: However, for optimizing engine performance, fuel availability, toxicity and political advantage, a blend of ethanol, methanol and petroleum is likely to be preferable to using any of these individual substances alone." I'd guess D-20 qualifies as a blend, with emulsified water, so chances are pretty high that corrosive nature of methanol is less of a factor. Cool beans! HB
