Ethanol production from corn has tripled the price, but much of it is market
anticipation in the Chicago Board of Trade pits and not the demand over supply price determining reality.
Commodity traders are very good at boosting markets on fear. $6.00 a bushel corn has $3.00 worth of fear in it. $100 a barrel oil has at least $50 worth of
fear in it. $150 a barrel of oil has $100 of fear in it, but that burns out quickly and the price falls.
Ethanol
brings problems to the fuel market. While it will mix with
gasoline
it is not transportable in existing pipelines. It contains water
that corrodes the pipelines and pumps causing large leaks. It is
also
hygroscopic; acquires water from
air, diluting the product and rendering the gasoline-ethanol mix
unusable as fuel. Chemically removing water
from
ethanol is expensive and time consuming.
Ethanol a consumable
intoxicant and heavily taxed in that form. If we produce large amounts of
pure ethanol it must be expected some of it will go into bootlegging
operations where ersatz whisky, gin and vodka can easily be made by mixing pure
alcohol with syrups and flavors to avoid taxes. This would balloon the
ATF bureau while the price of world corn skyrockets to create international
problems inflating the price of beef and the tortillas of
Butanol, the four
carbon alcohol solves all these problems, and many more. It is 100
octane, ping free and produces as much power as octane, the prototype gasoline
molecule where ethanol produces about 70% of the power of octane.
Butanol is less volatile than gasoline. This means it
does not evaporate as quickly and produces much less flammable vapors making it
a safer fuel in storage and accidents. Butanol can be used in
today's cars without modification. It can be transported in pipelines as
it is not corrosive to the seals used in pipelines and pumps.
Butanol can be made from waste corn and wheat stalks, grass
clippings, wood chips, sawdust and any other cellulosic material or
"stover." The bacteria responsible for this
chemical miracle is Clostridia acetobutylicum. It has been in wide use
since 1916 and it can be bred to work in a wide range of temperatures and with
virtually any cellulosic raw material including cheese whey, now an industrial
waste.
Butanol fermentation systems working entirely on sun
powered heaters won’t need expensive carbon based fuels. They require
one time building and assembly being little more than plumbing and computer
controlled pumps. They should run for decades with minimal maintenance. Where yeast fermentations need a lot of heat
and only produce 15% product the bacterial kind work over a wider range of
temperatures and produce up to 35% product before the product poisons the
process.
A new bacterial technology called TEnbox™ in which the bacteria grow faster, some report 50 times faster, has been developed and is under further study, but one of the exciting aspects of butanol production is that it does not require distillation that uses huge amounts of energy. It is only necessary to chill water down to 0 degrees Celsius, but not freeze, and 93% of the butanol separates to float on the water where it can be decanted off. This process can be done in any location and some climates offer special advantages.
Bacteria are easy to modify as their generations are
short lived. Were we to set up ten samples of a strain of Clostridia
acetobutylicum using a particular kind of raw material we would find that one
of the fermentation vessels worked a little better than the others. We
could use the contents of that vessel to seed the next round of fermentations
and another would be the winner in our set of conditions. In eight or ten
rounds of this work we would soon have a new variety of Clostridia
acetobutylicum ideal for the location.
We can fine tune the bacteria to work
well from
Recently (Feb. 2008) Dr. B. Gregg Mitchell of Scripps Institute of
Oceanography gave a talk about future energy sources wherein he stated
that while we could get 48 gallons of Diesal fuel from an acre of
soybeans annually, 113 gallons from an acre of peanuts or 124 from an
acre of Rape (Canola) seed we could get 15,000 gallons from an acre
devoted to algae culture which now exists experimentally in Calapatria,
California and could be marketed for $2 per gallon. The really
exciting idea is that of setting up such farms in calm bays like much
of Baja, California which could easily make all the fuel needed in
north America.
Politics hold this technology
back while the elected class titillates the farm lobby and runs the price of
corn up. The nation is more important than any special interest group. Butanol technology is here now. It is the fuel of the future.
