Yes your are right when you are saying that it isn't possible with the state of the actual agriculture to deliver all the fuel which is needed.
But Nature has still more possibilities we all can dream of!
1. Instead of building flex-fuel-cars it is better to build smaller cars with motors that run on only one fuel. It is much easier to design a motor for only one fuel and the motor is more efficient (less compromises).
2. You can get vegetable oil from a field plus (!) the usual yield of corn, wheat, etc. when you practice the method of intercropping (
http://en.wikipedia.org/wiki/Intercropping ) respectiveley mixed intercropping. A good mixture is e.g. false flax or gold-of-pleasure (Camelina sativa) in combination with grain (Wheat, rye, etc.) or even better together with legumes (peas, beans, etc.). A study in Germany showed that you can get up to 270 Liter of false-flax-oil per hectare (about 2,5 acres) by growing peas together with false-flax. So you get even more oil than you need for processing the culture till the harvest.
3. David Blume explaines how to produce efficiently and with competitive prices alcohol (e.g. in the following document about using food waste or agricultural waste):
"Selecting feedstocks" (for making Alcohol)
http://www.alcoholcanbeagas.net/book_me ... 29/384/429
So you need no pipeline to transport ethanol or other alcohols around the states.
You grow your fuel at your site!
No transport with oil spilling supertankers, no explosions in big refineries, no hazard through pipelines.
4. He also explaines that there are not only 434,164,946 acres of “cropland” in the US, but also 939,279,056 acres of “farmland, but it’s not as level and the soil not as deep.
Permaculture (Geoff Lawton and his miracle at the Dead Sea in Jordania; P.A. Yeomans and his Keyline-System (
http://www.yeomansplow.com.au/yeomans-k ... system.htm ) together with his method to convert quickly poor soil into fertile ground:
http://www.soilandhealth.org/01aglibrar ... 25ch5.html) can do a lot for the soil and for the water-cycles in nature, especially in the actual situation where the Ogallala-Aquifer is running empty.
5. Oilseed crops are producing the more yield the more sun they get: peanut, sunflower, olives, etc.
There are other plants like jatropha bush which grows and yields oil containing nuts even in dry conditions.
6. In southern states with dry regions millet is also a possibility to grow food for animals.
7. Once hemp is reintroduced again all the problems with water supply are problems of the past: Hemp needs only a fraction of the water cotton needs to produce a certain amount of fibres. It enhances the soil, needs very few fertilizers and almost no pestizides or herbizides. So this plant would be a economical miracle.
Guess who prohibited the cultivation of hemp in the USA!
There are Bacteria, called Rhizobacteria, and among them is
a special type which can convert aeroeus nitrogen into nitrogen which can be absorbed by plants (for Legumes as well as for grain crops!).
Now guess which companies have a patent on Rhizobacteria?
It's ESSO CHEMICAL CANADA and Agrium Inc. (a small tiny fertilizer production company,formerly known as Cominco Fertilizers (Calgary, CA)). Funny, isn't it. A Big Oil company investing money in a quite useless technology.
You have to search for the following names:
Kloepper, Joseph (Georgetown, CA, US), Scher, Fran (Bramalea, CA, US)
These are only some impressions what else is possible by working together with Nature in a smart and wise manor.
