I'm aware that hemp has uses. :)

And I think as an economic crop, hemp qua crop makes sense. Trying to get it
accepted is another matter, a propaganda matter.

However, regarding hemp qua fuel: inasmuch as hemp still has to be cultivated,
there's an energy cost associated with that. Assuming hemp is as efficient as
soybeans at generating oil (that seems like a conservative estimate), and
assuming similar cultivation/processing costs (not sure this is true), a first
approximation of the energy credit (or debt) ought to be easily calculable. I
don't have the numbers at present. But we don't see a lot of soybean-powered
cars, do we? Now if hemp were incredibly better as a fuel, or incredibly cheaper
to cultivate, this use might still pan out. I'm curious to know if the book you
mention goes into this, or just handwaves about it.

I'll try to look up that book. Have you got an ISDN number handy? Thanks.
