Re: [hreg] Methane digesters
I never said anything about easy, as a matter of fact I said I would be
building a small one to get acquainted with the process. The processors
in Nepal are built for family farms, not agribusiness. I am aware of
the problems with temperature, but also the problems of scale. Chicken
factories have a totally different set of values from a sustainable
farm, what we think is worth doing, agribusiness doesn't. Cost benefit
to a sustainable farm is very different from agribusiness. We are
concerned with more than just dollars and we don't use paid help. If I
believed the statements of agribusiness, I wouldn't have a farm. They
are forever telling me I can't do what I do, do.
