Dept. of Energy Rejects Corn Fuel Future

eldavojohn writes "The United States' Department of Energy is stating that corn based fuel is not the future. From the article, "I'm not going to predict what the price of corn is going to do, but I will tell you the future of biofuels is not based on corn," U.S. Deputy Energy Secretary Clay Sell said in an interview. Output of U.S. ethanol, which is mostly made from corn, is expected to jump in 2007 from 5.6 billion gallons per year to 8 billion gpy, as nearly 80 bio-refineries sprout up. In related news, Fidel Castro is blasting the production of corn fuel as a blatant waste of food that would otherwise feed 3 billion people who will die of hunger."

three billion?

Even if you buy their generous estimate of 35K deaths/day, that's over 200 years to reach 3 billion deaths.

Because the diesel/electric motors in trains aren't done for efficiency reasons, they're done because of space constraints.

First, trains don't have batteries. It's just:
engine->genset->electric motor.

Diesel engines (especially large ones) work within a very narrow power band. For on highway trucks it's around 1000 - 2000 RPM. This is great when pulling a heavy load, but it means that you're gearing has to be set up accordingly. This is why 18-wheelers have 13 speed gear boxes.

With the amount of torque that trains need to get up to speed the gear box would need to be as long, if not longer, than the train itself. You'd need a 10000:1 (made up number) gear ratio to get the train moving, but that ratio would only be good for 1000-2000 RPM, so you'd have to shift to 9999:1, etc.

The genset -> electric motor works great because the electric motor has a near infinite 'gear ratio' and provides peak torque from 0 RPM.

However there are losses, you'll never get better than a drive where the engine is connected directly to the wheels, this is why some automatic transmissions allow you to lock up the torque converter.

Diesel hybrids are coming, but the gains over a traditional diesel engine aren't as great as over a gasoline engine.

Bullshit! Read the fucking editorial, it is in spanish, if you can't read get someone to translate it to you. I quote here:

"(...) independientemente de la excelente tecnología brasileña para producir alcohol, en Cuba el empleo de tal tecnología para la producción directa de alcohol a partir del jugo de caña no constituye más que un sueño o un desvarío de los que se ilusionan con esa idea. En nuestro país, las tierras dedicadas a la producción directa de alcohol pueden ser mucho más útiles en la producción de alimentos para el pueblo y en la protección del medio ambiente."

Translates (roughly) as:

Independently of the excellent Brazilian ethanol production technology, in Cuba the use of such technology to direct production of ethanol from the sugar cane is nothing but a dream or a fantasy from the ones who have illusions with this idea. In our country, the soil dedicated to the direct production of ethanol can be much more useful in the food production for the people and for the protection of the environment.

So, stop spreading lies and RTF Editorial.

"Unless I'm missing something in translated translation, I looks to me that he is saying their soil is better for food and they won't be doing it."
No, he is saying, although their soil is appropriated for sugar cane (and I add, dutch, spanish and portuguese fought for it in the past exactly because of it), he believes the soil better use is for food, because people is more important that everything else. That's the point of the whole article.

Nothing about the GP's stating he wanted sugar cane used so his crops would be worth more.

GP implied that Fidel's interest on shifting the ethanol production from corn to sugar cane is benefitial to Cuba. Fidel's point is that everything ethanol is bad if land that could be used to produce food is used to produce fuel.

In case your wondering, taking the majority of the competitions product off the market makes your prices go up. It is the free market thing."

Yes. Except that there is no Free Market in Cuba. And that, even if there was, there is this little thing called U.S. mandated worldwide embargo on any Cuban export, so they couldn't benefit from it. Don't they teach those things there on history/geography classes?

I don't think jobs are the problem, but the supply of food.

Actually, famine nowadays is rarely a function of food supply alone. per Wiki:

Modern famines have often occurred in nations that, as a whole, were not initially suffering a shortage of food. The largest famine ever (proportional to the affected population) was the Irish Potato Famine, which began in 1845 and occurred as food was being shipped from Ireland to England because the English could afford to pay higher prices. The largest famine ever (in absolute terms) was the Chinese famine of 1959-60 that occurred as a result of the Great Leap Forward. In a similar manner, the 1973 famine in Ethiopia was concentrated in the Wollo region, although food was being shipped out of Wollo to the capital city of Addis Ababa where it could command higher prices. In contrast, at the same time that the citizens of the dictatorships of Ethiopia and Sudan had massive famines in the late-1970s and early-1980s, the democracies of Botswana and Zimbabwe avoided them, despite having worse drops in national food production.

According to Nobel-peace prize winning economist Amartya Sen quoted here, there is without exception a political component involved that allows the food shortage to progress beyond food insecurity:

I have discussed elsewhere the remarkable fact that, in the terrible history of famines in the world, no substantial famine has ever occurred in any independent and democratic country with a relatively free press. We cannot find exceptions to this rule, no matter where we look: the recent famines of Ethiopia, Somalia, or other dictatorial regimes; famines in the Soviet Union in the 1930s; China's 1958-61 famine with the failure of the Great Leap Forward; or earlier still, the famines in Ireland or India under alien rule. China, although it was in many ways doing much better economically than India, still managed (unlike India) to have a famine, indeed the largest recorded famine in world history: Nearly 30 million people died in the famine of 1958-61, while faulty governmental policies remained uncorrected for three full years.

There's no such thing as U.S. mandated worldwide embargo. I am from Brazil and had a girlfriend workin for a company which has some factories in Cuba (Souza Cruz Tobacco). You can find Cuban products (not so many of them) in almost every city on Europe (including U.K.), South America and Asia. Also, major european Hotel companies have business in the island. Fidel Castro also receives a lot of oil for free from his ally Hugo Chavez. The embargo applies only to American companies, and it's perfectly just, as american citizens and companies that were expropriated by Fidel's revolution never received compensation for the theft. Don't they teach those things there on history/geography classes?

Re:zombie castro said what?

Hey man, seems like we went to the same schools tho, because I'm also a Brazilian :) Anyway, you may want to read the Helms-Burton Act, passed in 1996 by the U.S. congress, and that mandates, among other things:

* International Sanctions against the Castro Government. Economic embargo, any non-US company that deals economically with Cuba can be subjected to legal action and that company's leadership can be barred from entry into the United States. Sanctions may be applied to non-U.S. companies trading with Cuba. This means that internationally operating companies have to choose between Cuba and the US, which is a much larger market.

IF that is not enough an worldwide embargo, what is?

And I know they teach this on Brazilian schools, so, let's cut the "don't they teach this" thing and move on.
