Hey Jack, what exactly do you think farm tractors run on, sunshine?

Hey, Genius. Do you think those tractors are just sitting idle unless they're producing corn for ethanol? Naw. I reckon they're out there in the fields burning fuel whether they're producing corn for livestock feed or for feeding SUVs.

Please relay to everyone how the U.S. halting buying oil from the Arabs is going to change anything?

Gladly. You'll notice I didn't say anything about "shutting down the Arabs." I don't care what the rest of the world does. But if the US could become independent of Arab oil, then fewer AMERICAN dollars would enrich a bunch of thieving Bedouins.

All that would happen is we would buy from the Norwegians or Russians and the the Arabs would sell to them.

You slept a lot during math class, didn't you?

Tell everyone how that will shut down the Arabs.

Naw, you go ahead. That's YOUR thesis, not mine.

The only pockets that will get hurt will be ours as we would pay even higher prices for imported oil.

Was Econ right after math?

Ethanol from corn is barely feasible.

Well, yes and no. Ethanol, without by-products, from corn is barely feasible. The value of the gluten or DDG's (as well as the existence of cash and futures markets in corn) make corn ethanol quite feasible.

YOU CAN GROW HEMP IN A WHOLE HECK OF A LOT MORE LAND WITHOUT THE TOXIC CHEMICAL USED FOR COTTON. THE MULTIPLE USE FACTOR FOR FUEL OIL IS JUST ONE OF THE PLUS ITEMS.

THANKS FOR THE RESPONSE. TIMELY.

I see it this way:

The Arab countries produce only two things: oil and terrorists. They import everything else, including food (to feed terrorists), cloth (to hide suicide bomb belts on terrorists), industrial chemicals (to make suicide bomb belts for terrorists), and manufactured goods (such as AK47's to arm terrorists).

Only one of their exports, the oil, can be considered a trade good with a market value (they provide the terrorists to the rest of the world gratis). That makes oil their only source of income to use in exchange for the products they import (such as food, cloth etc).

When a major oil comsumer like the United States develops viable alternatives to Arab Oil, regardless of whether it's Arctic Wildlife Refuge Oil, or BioDiesel, or Wind Power, or Nuclear, or whatever, the worldwide consumption of oil decreases. The lower international demand means a lower price for oil on the international market, meaning less money flows into Arab countries for them use to to buy food, cloth, etc. for raising, equipping, and exporting terrorists.

Facts won't matter here.

hmmm. I thought it was the evil professors at the liberal universities that we weren't supposed to side with. I guess I was wrong.

You obviously didn't read the article. It takes more energy (oil, natural gas, nuclear, whatever) to produce ethanol than it produces.

Do you believe everything you read?

Ever listen to Dr. Bill Wattenberg on KGO San Francisco? He has reasoned for years that ethanol is a waste of energy, as well as solar power. He testified to the California legislature about the carcinogenic effect of MTBE before they made it mandatory in gasoline. He's been working in the energy and defense fields for decades; he is a scientist armed with facts, not prejudice. I trust what he says. He is an advocate of nuclear power, in fact, he has worked on the building and disposing of waste from the plants. Check out his show's website at pushback.com.

The numbers I have for oil production from industrial hemp (Cannabis sativa) result from similar amounts of fertilization, irrigation, pesticides, and whatnot as the other crops. Hemp will grow without fertilizer, irrigation, pesticides, and whatnot (like all plants), but not nearly as well and with a massively reduced yield (especially seed oil yield).

USED FOR COTTON.

But we are not discussing cotton or other fiber crops. We are discussing energy crops. Industrial hemp is a very good fiber crop. If you want to make cloth or paper, industrial hemp would be a very good idea (if it were legal). However, industrial hemp is a poor energy crop. If you want to fuel your car, grow rapeseed or something better.

THE MULTIPLE USE FACTOR FOR FUEL OIL IS JUST ONE OF THE PLUS ITEMS.

Now if you're talking about taking the extra seed byproduct from growing hemp for fiber and putting it into a general oil seed feedstock for producing energy, then there's nothing wrong with your position. However, the low oil energy per acre output for hemp (especially compared to it's high fiber per acre output) means it will never be more than a tiny blip in any renewable energy economy.

If you're advocating growing hemp specifically as an energy crop, there are many significantly better energy crops out there.

"Ethanol also burns out the fuel injectors and the fuel line linings."

I lost your meaning. Are you saying that ethanol cleans the fuel injectors and deposits in the fuel line? I think it is the use of the word "burns." The use of the word "burns" could mean a corrosive effect. I am do not know how there is a corrosive effect from ethanol since this entire system is metallic.

But there are much better fuel crop sources for Ethanol than Corn.

And much better renewable fuels then Ethanol.

If a farmer is looking to maximize his subsidy income, growing corn for Ethanol is a good idea for him. If he is looking to maximize his BTU production, growing rapeseed (or another oil crop) for BioDiesel is a much better idea.

Farmers pay the bills with dollars, not BTUs, so they grow corn for Ethanol.

"No, YOU misunderstood IronJack's meaning. Whether or not ethanol takes more energy to produce than it gives off as a fuel (kind of disproven by Bommer's posting), IF we use American coal as the source of fossil energy for the distillation process (the biggest "energy hit" during production), this displaces a large amount of foreign crude oil--far more than just the ethanol produced."

Then you both are a little dim, because you might as well crack the coal to begin with instead of creating a massive farm welfare state. Unless that's the goal, in which case we might as well go back to burning wood in steam engines because that would certainly create more work.

And if you are going to all this trouble, why not just go nuclear in the first place. I think you guys are just Rube Goldberg wannabees.

"There's no term in a thermodynamics equation that includes a financial term. "

Sure there is, it is a stand in for free energy costs which contain an entropy term. So you don't know what you are talking about.

"When a major oil comsumer like the United States develops viable alternatives to Arab Oil, regardless of whether it's Arctic Wildlife Refuge Oil, or BioDiesel, or Wind Power, or Nuclear, or whatever, the worldwide consumption of oil decreases. "

Not really, it simply flows elsewhere in the world. This increases production in those countries, which at first subsidizes them because of the lower cost, however more production leads to - more production, So the long term use of oil and profits to the Arabs is not much reduced, and may be paradoxically increased.

Methanol from corn production is a good idea. The waste from such production has high value uses that can be sold to offset its costs.

I might add that a new process may take the ethanol process one step further. There is a chemical engineer that has developed a process to make diesel fuel directly from any organic material. Now the corn cob and the corn stalk can be used to make diesel fuel, along with garbage and any waste product that has carbon. The fuel vapors from the process provides the energy to crack the molecules down to fuel grade diesel. Is it soup yet?

...it takes 29 percent more fossil energy to turn corn into ethanol than the amount of fuel the process produces.

But maybe if the Government spent a few hundred million (not suggesting that anybody should spend any of their money) to build an ethanol pipeline infrastructure to transport the fuel we could cut this down to only 20 percent?

Then again, how about we just let the market forces decide. Historically speaking the market has a pretty good track record.

Good idea, although I would be happier if it were off Martha's Vinyard. Good tag line!

You are making one false assumption. You are assuming that if the United States reduces or eliminates it's demand for Arab Oil, that demand will be taken up by other countries so that the worldwide demand for Arab Oil will remain the same.

Which is patently untrue.

Sure, other countries may increase their Arab Oil consumption of prices decline because of the elimination of the U.S. demand, but in no way would such an increase be sufficient to match the eliminated U.S. demand. We consume a LOT of oil, and industries can only expand at a limited rate. Countries consume the oil they can afford, or their economies and industries require. They do not purchase oil just to waste it (despite what the Anti-SUV tree hugger crowd might say).
