There are a number of ways in which many farmers, both those on the
sustainable side and the heavy chemical users, can reduce the use of on
farm use of fossil fuels. One of those is to capture and use at least some
of that methane that is generated by farm animals and the decomposition of
their manure products. A few in the sustainable community have used, or
are still using methane on the farm and a very few may even be suing it in
But I am wondering why there is not more emphasis on finding and using
alternative forms of energy. One alternative form which is a result of the
space program is hydrogen fuel cells. Hydrogen fuel cells produce
electricity without producing any harmful emissions. ZERO emissions. A
few have been used experimentally in city buses and maybe elsewhere, but
there seems no support for it i government circles. Or at least very
little visible support. I wonder why this is so? Could it be the
officials in the Departments of Commerce and energy do not want to upset
the oil companies?
Hydrogen fuel cells have come a long way and are quite efficient now as
well as being light weight enough to almost completely offset the lower
output obtainable than that from fossil fuel engines.
If every one agrees that the continued use of fossil fuel is a major
cause of the global warming, and also that we are rapidly exhausting the
world supply of these fuels, why is there so little effort now being
devoted to converting to alternate sources of energy? Anyone care to comment?
