I'm for butanol as a fuel source too, if Dupont and others can make it available at a reasonable price. However, I thought I'd make the case for non-corn ethanol too. I am an environmental professional and I would like to point out that there are major efforts underway right now to produce ethanol from other forms of cellulose and starch including from municipal solid waste. There are plants which will go beyond the pilot scale in the next calendar year to use municipal waste as a carbon source for ethanol. I assume the technology could be converted to produce butanol in the future if the bugs can be trained properly.
