- Subject: biomass fuel????
-
- again here is another bogus argument for legalization. I happen to have
- gotten a degree in geographer with an emphasis on economice geography, in two
- classes i took we focused on biomass for energy and the facts are that NO
- plant including hemp is going to be able to compete with other fuel and
- energy sources, the main expense is capital equipment costs and the amount of
- biomass is not even the second largest cost, its labor.
-
- i met jack herer once and pointed out what i considered an error in his
- thinking about methenol. it appears to me that he assumes that a gallon of
- methenol is equal to a gallon of gasoline(octane) however octane is about
- twice as energetic as mentenol by mass and volume(which are nearly one to
- one) he said he would check once he got back to calif. but i never heard from
- him again.
-
- mentenol is no pollution salvation either, what you make up in CO2 scrubbing
- in growing hemp is lost by the production of NOx and carbon monoxide in the
- tailpipe.
-
- right now petroleum is selling for about 15 dollars per 50 gallon barrel
- which means a synthetic version would have to sell for the same to be
- competive. when the united states tried to develop a synfuel industry based
- on coal in the early 80s they found that to be competive oil would have to be
- about 50 dollars a barrel or higher.
- with coal you already had a concentrated supply of organic material and the
- industry couldn't make against low priced oil.
-
- besides there is a lot of biomass for the taking out there it is called
- municipal waste sludge and does have porperties similar to peat.
-
- dollar for dollar if i was in charge of investing to create alternative
- energy sources i would never put money into biomass. solarvoltiac and wind
- power would give a higher(positive at least) return.
-
- the fact is that plants in general are very inefficent at capturing the
- energy in sunlight. even in the best conditions plants can only utilize about
- 2% of it. clorophyll is specific to about 630nm(nanometers) wavelengths of
- electromagnetic energy(light) whereas solarvoltaics as efficent as 15% have
- recently been developed in australia and relatively cheap one at 10% are
- available now.
-
- i would suggest reading a magazine called independent energy if one is
- interested in the professional thinking among those actually puttting money
- into new sources of energy. biomass is not a big topic there. cogeneration,
- solar, wind and hydro are.
-
- i think that industrial arguments are never going to sway someone who already
- thinks the smoking marijuana is a bad thing to do. it has not work well
- outside the hemp community itself. to me, a picture of a seventy year old man
- in prison for the rest of his life for a marijuana only charge is much more
- persasive.
-
- paul
-
- just to make things clear i think hemp for fiber and paper are sound
- arguments technically but still lack the kind of emotional pull that a human
- rights argument has.

- There are those people, rather well qualified, who would disagree with
- you here. Folke Dovring points out in his book, "Farming for Fuel" that
- fossil fuels are actually heavily subsidized through United States DoD
- funding. When this cost is factored in, methanol is roughly competitive
- to current oil prices, per BTU.
-

-
- Properly built and tuned methanol engines do not do this. South America's
- formaldehied problem could be cured overnight by a massive campaign of
- auto mechanics.

- .. with a *much* higher initial investment, and without the advantages
- of a liquid fuel (unless you want them to pay for the technology
- to produce hydrogen, too.)
-
- Even relatively cheap ones are beyond the means of most farmers. Keep
- in mind that it is very inexpensive to cover acres and acres of land
- with hemp plants.
-
- Energy companies are currently burning
- *trees* as a source for electric power. I can see a clear demand
- for hemp biomass here.

-
- Agreed, and it is these industries which will bootstrap the biomass
- fuel industry by producing enough spare feedstock to develop
- a technologically advanced pyrolytic fuel reactor.

-
- i work for a publisher of scholarly journals and one of my favorites is
- called the journal of non-renewable resources. in an article that addresses
- your question, petroluem supplies could last forty years or longer. depending
- on if you project increasing consumption, new proven reserves, currently
- non-economic deposits( for example there is a lot of oil under ohio but it is
- in micro-field that would warrant a well) the figure could stretch out to
- about seventy years. in addition to that there are tremendous supplies of
- natural gas and coal in the world as well tremendous potential in wind and
- solar power.
-
- just because something is technically feasible does not mean it is
- economically practical.
-
- as an enviornmentalist i am hopeful for a completely non-carbon based fuel
- system for cars, hopefully electric, even burning compressed or liquid
- hydrogen creates NOx compounds because nitrogen in the atomosphere is still
- in the combustion chamber.

-
- Noone has gotten that far -- all the countries with a hemp industry older
- than a deacade have little in the way of technology. China is the
- most advanced. However, they may have started a pilot project to burn
- raw hemp feedstock in Australia in the generation of electricity.

-
- Formaldehyde is what concerns the South American countries with
- methanol vehicle fleets. They don't seem too concerned with Nitrogen
- compounds. There are a whole host of environmental problems with electric
- cars, mainly in the manufacture of the parts especially the batteries,
- which you fail to mention. Internal combustion is still a superior
- technolgy for small passenger vehicles, though hybrid models show some
- promise of increased efficiency.

-
- No, power companies are actually growing trees to burn instead of coal.
- They have developed fast growing pines that even rival hemp for biomass
- production. These are whole-tree harvested and used for nothing but fuel.
- Something you also neglect to figure in are all the useful
- industrial byproducts of the pyrolytic process.
