Kermit,
They make great cattle feed and the ash content is high enough to cause
clinkering problems. There are just better uses for them.

Subject: [Gasification] questions
One majorquestion that I have about gasification is why corn cobs are
not mentioned moreas a major fuel source. There must be a lot of them and as
combined heat andpower they could keep farm houses, schools, and apartments
warm. I know thatsome of them are returned to the soil and some are probably
used to distillethanol. Wouldn’t it be better to distill the ethanol with solar
energy or withcombined heat and manufacturing (comanufacturing)? Is cellulosic
ethanol likelyto become important? Another question is, can we gasify the cobs
and thenreturn the ashes to the soil or must we put carbon back to the soil
tofertilize it? Would powdered coal stayindefinitely in the soil and do the
same thing? On this list I have seenopinions on both side of this but I hope
someone knows the truth.
Sincefertilizer is all important to gasification and it will be
scarce, we shouldconsider the use of sewage for fertilizer. One of the reasons
that sewage issaid to be unfit is that medicines and other impurities would
poison us.Wouldn’t gasification destroy many of these organic compounds and
thus purifythe ashes so they could be used as fertilizer for food crops?
Inorganic compoundsprobably would not be destroyed and in recycling fertilizer,
salt might be theultimate pollutant.
Tom Reed’sgasification driven tractor seemed to me to be one of the
best gasification projects.I did think that the sheet metal would rust pretty
quickly and that it neededcast iron. I wonder if it ever worked enough to plow
with. I believe that somefarm made ethanol used as a starting and power
increasing fuel might make itmore practical. Making farming self supporting in
terms of energy seems like agood idea.
There are manycorn fields surrounding Ann Arbor yet the best energy
project the city has cameup with is a large array of solar panels. Why not use
those corn cobs? Where isthe propaganda machine for biomass energy? I believe
that available biomassenergy is greater than either solar or wind but the
environmentalists ignoreand deplore it. One way to advertise the virtue of
biomass energy would be tocreate a large farm with an apartment on it.
Gasification, can combine heat andpower for the building and also create enough
fuel for plowing from farmbiomass. This would create a huge advertising of the
need for gasification.
