I'm not big on subsidies for things that are not economically feasable. If a
bunch of folks want to get together privatly and make the stuff and sell it to
each other, that is fine. But until it is competetive with other fuels,
taxpayers whould not be footing the bill.

I'm the same way, the problem is that our current system doesn't price
in the cost to the environment, so poluting solutions cost less in the
short run. I think they call it "Tragedy of the commons", the idea
that since the environment isn't owned by anyone, people use it and
trash it, each person extracting the maximum short term benefit from
it. Its a real problem.

If it is denser, as the description of power and economy implies (like diesel
versus avgas, fewer gallons per hour but a gallon weighs more) maybe it isn't a
bad deal. Do you happen to know the density of biofuel versus diesel, or the
BTU's per unit volume or anything like that?

My recollection is that they are almost the same.
