The Great Ethanol Scam
theodp writes "Over at BusinessWeek, Ed Wallace is creating quite a stir, reporting that not only is ethanol proving to be a dud as a fuel substitute, but there is increasing evidence that it is destroying engines in large numbers. Before lobbyists convince the government to increase the allowable amount of ethanol in fuel to 15%, Wallace suggests it's time to look at ethanol's effect on smog, fuel efficiency, global warming emissions, and food prices. Wallace concedes there will be some winners if the government moves the ethanol mandate to 15% — auto mechanics, for whom he says it will be the dawn of a new golden age."
It's next to impossible to find a gas station that does not have Ethanol in it's fuel. It doesn't help that two huge ADM plants are with in 90 minutes of where I live. Regardless, there is a single Shell station in the area that has 93 octane V-power that is without ethanol. The cost different of $0.30/gal is offset by the noticeable decrease in fuel consumption, increased power, and smoothing the idle. Yes, my car is tuned to require at least 91 octane.

I'm sorry, but your argument is bullshit.
At first, ethanol in Brazilian fuel is nothing more than a subside for northeastern Brazilian farmers, just like it is a subside for US corn farmers. It's not economically friendly. It's a more like a farming sweat shop. Northeastern Brazil is, by far, the country more backwards place. Workers live in substandard conditions and slavery is not really uncommon in poorest places.
At second, it's not environmentally friendly. Sugar cane is burned before being harvest. Particulates and smoke are really bad for neighbor population. Lack of crop rotation impoverishes the soil.
I'm a Brazilian myself and, obviously, new exports are always welcome. But not sugar cane. Let it die. It's just a way for the the country semi feudal elite to keep exploiting poor people, like it's being doing since 1500. Let the soil grow food. It's not a solution. It never was.
English is not my first language. Corrections and suggestions are welcome.
Other types of biofuel may be better than corn, but they have their problems too. According to a shocking report by "Time Magazine", "if the world gets even 10% of its energy from these new kinds of crops, most tropical forests will probably disappear."
Not surprisingly, lobbyists for American agribusiness are angry as hell about the conclusions of the EPA study.
Really, the best way to partially fix this nonsense is to make Iowa (and its corn farmers) the last state to participate in both the Republican primary and the Democratic primary. Due to the importance of Iowa as the first state in the presidential primaries (including caucuses), Iowan agribusiness has a stranglehold on American politics, and its politicians do stupid things (like supporting corn-based ethanol) in order to cater to Iowa.
Also, has anyone noticed that no one has mentioned the #1 reason for the growing energy problem and its associated pollution problem? The #1 reason is overpopulation. If we reduced greenhouse-gas emissions by 3% over 10 years but increased the population by 3% over the same period across all nations, then we effectively accomplished nothing.
Can anyone guess why overpopulation is never mentioned by American politicians? Could the concept of overpopulation be too closely tied to illegal immigration?
In Brazil, you can buy your alcohol cheap!
On a more serious note, all this ethanol scare tactics are BS. The problems that ethanol cause with food prices are because the US is using corn as a base source. If they used a more sensible crop like sugar cane it'd be better.
I've been to Brazil, I've seen how well their ethanol infrastructure works. To all you ethanol haters/fear mongers I have only this to say:
It works, bitches.
I hate printers.
but the main reason we use corn is that the price of corn is below the cost for the farmer to grow it... and we have square miles of it piled up lying around, that's why it's subsidized. Farmers see ethanol as a way to sell their crop at a PROFIT... imagine that.
The original Model T was designed to run on Ethanol, the idea of Ford was that the farmers could still their own from their own crops. It wasn't until Rockefeller got involved that the political tables turned to oil.. and because of the higher temps of gas engines, they had to use Lead additive as a buffer (which they already knew was poisonous) versus ethanol, which ran cooler but wasn't "flashy".
In Brazil, ethanol production is a bright star in this world of diminishing petroleum reserves. Alcohol exports reached a record of nearly 1.4 billion gallons last years. Most ethanol is produced from sugar cane. Most sugar cane is cut by hand. It is hard, arduous labour. The "cortadores de cana" (workers) are paid directly based on the quantity of sugar cane they cut - so there is no such thing as holiday pay, sick leave, or coffee breaks. Time not cutting cane is money lost. Now that is the best scenario. Often, slave labour is employed on farms and in sugar cane fields in Brazil. Every month there it seems workers are rescued from another slavery operation. It makes one wonder how much is not discovered. If it is not slavery, it is sugar cane cutters who are paid in drugs. Once addicted to crack cocaine, they'll keep on working for that next fix. Now, the president of Brazil is a very enlightened man, and on the side of the common workers. In fact, his party is called the Workers Party. He is very concerned about the sugar cane cutters - Not at all! One would think the cutters would be the first to benefit from record sugar cane profits, but they are forgotten once they burn themselves out cutting cane. Meanwhile, the big producers get richer off the sweating backs of the workers, and the politicians get richer off the backs of every one. This is what I have heard, anyway. In Brazil, it is best not to say things like this - wiser to post anon.
I am Brazilian, an engineer and was also an early adopter of the Ethanol technology, having Ethanol cars since 1982. I converted three of my family's cars from Ethanol to Gasoline in 1990 - due to a extreme short supply of Ethanol at that time - when I learn by practicing how different were the cars.
Some information about the Brazilian experience:
- Early on the Brazilian automotive industry realized the alcohol fuel (mostly Ethanol plus some water and other impurities) corroded standard fuel systems. Every part of the fuel system had to be re-engineered, in particular metallic alloys. Note that the players in Brazil at that time were GM, Ford, Volkswagen and Fiat. It strikes me the US automotive industry has not warned consumers about this fact.
- Ethanol packs less energy per mass unit or per volume unit. Nevertheless engines can have higher compression ratios, compensating in part the gross energy deficit by converting more thermal energy into kinetic energy. In fact the addition of Ethanol to gasoline has the positive effect of "elevating its octane index". Pretty much as lead additives used in the past. Overall, similar models prepared to burn alcohol were quicker but they also spent more fuel per mile - other conditions being the same. Which was mostly perceived as a nice trade-off. So in the shot term you will have an engine with less pre-detonation.
- Sugarcane is damn efficient in converting solar energy into sugar. Moreover most sugarcane crops are be located in tropical (by definition) ares. Compare the solar power received in Latitude 36 with Latitude 23. The US Ethanol energy output is double handicapped, both by a low quality crop (for the purpose of producing alcohol) and by a lot less solar power.
- Ethanol fuel generates different pollutants. In particular it generates aldehydes. There is smog after all, although of a different quality.
Besides, the fuel consumption in Brazil is a fraction of the US. There are less cars there and they tend to be a lot smaller - and more economical. The Brazilian Ethanol program success cannot not be remotely considered to be a model for the US. The US have other energy sources that make a lot more sense, such as coal and natural gas.
I have believed the US Ethanol program is a lot wishful thinking fueled by quite questionable agendas. As the article says.
