Scott,
There is a lot of opposition to any alternative fuel that is not 100 Octane. I don't know the particulars either as my brain isn't even geared for raising crops. (However, it does fairly well with fertilizer). If I'm not full of fertilized, the alternate fuel we end up with, will be half as efficient and cost half again as much, as 100LL. Sooner or later a battery or power source capable of providing very significant power will be developed and combustion engines will die on the vine. Already the technology exist to build windows with tiny bio-solar cells to collect power. But we need an efficient way to store the power generated. 10,000 golf cart batteries isn't the answer. But I think it would be great to get two or three of the proponents of alternative fuels to attend a Nationals. Maybe next year in Tahlequah?

He flew down to the meeting in an RV 10 which is powered by pure ethanol. He mentioned that the EPA has already petitioned Congress to eliminate the lead in aviation fuel. The Government is considering a UL 94 or a UL 84 as a replacement. It could be 92 and 82. It takes 1.5 times the amount of Ethanol to equal the BTU's of our present aviation fuels. I can't rmember all of the scientific data that he presented as my mind is trained to deal with fertilizers and raising crops as opposed to technical engine and fuel related properties. An engine that is rigged for Ethanol use can use 100LL, unleaded auto fuel as well as pure alcohol. The engine must be fuel injected also. It would be interesting to have him speak at an EOC convention. Maybe that can happen if we host the conv in Nebr. again. Scott
