The only change will come when your congress person knows they will be voted out of office if they don't start making wise decisions.
 
Wise decisions that are good for the constituency and not their re-election war chest.
  
Ethanol from corn has been foolish and has been costly and destructive to the economy.
 
And most of all to the environment. Think about the Dead Zone in the Gulf of Mexico. Probably more damage to the environment and fishery than the recent catastrophic oil spill.
 
An area the size of the State of Massachusetts is currently located in the Gulf of Mexico, called the “dead zone,” which is a vast marine wasteland where fish and other marine life can’t survive. The fertilizer and nutrient-rich sentiment wash off from area farmlands, causing massive algae blooms that deprive the dead zone of oxygen.
 
The dead zone is about 17-21 percent larger today, compared to the first measurement taken in 1985. Since 2001, five large record-breaking Gulf dead zones have been detected, with the largest measuring a massive 8,894 square miles.

The lower mileage ethanol produces ONLY happens in FLEX FUEL cars.
 
Brazil developed ethanol only cars that had GREAT mileage and performance.
 
However, just like diesel engines, ethanol engines cannot run on gasoline.
 
If the US sold those cars even the mileage problem you so well point out would be solved.
 
So, again, it is NOT a problem of ethanol in general, ONLY US ETHANOL.

Time for a reality check. If the US were to adopt ethanol only cars as you say are in Brazil, we would be in worse shape. We cannot produce enough ethanol to keep up with the 3% mandate currently in place. If we took off the tariff and bought all of your ethanol it would not be enough to power 5% of our vehicles. Then you would have all those ethanol only cars and no ethanol. You should be happy we are not buying much of your ethanol.
 
There will NEVER be ethanol only cars sold in the USA. We don't want the mess you had following the last time ethanol was all the rage in the 1970s. We have had flex fuel vehicles sold in the USA for well over 20 years. And there are about a dozen stations in the whole state of CA that sell E85. Only ONE in San Diego County where I live. And it cost more than gas.
 
Another thing you leave out in your exuberance for ethanol is transportation. You cannot just stick it in a pipeline and get it to market. It all has to be shipped by expensive tanker trucks.
 
Plus the USA already produces nearly twice as much ethanol as Brazil. And that is not enough to meet our current mandate.
 
For the USA Ethanol is a GIANT SCAM.

Time for a reading check.
 
Brazil uses only 1,2% of its land for ethanol production, and it produces it from sugarcane, which yields 9 TIMES more energy than american corn.
 
So you can be sure there would be PLENTY of ethanol for america.
 
And there was no "mess" in the 1970 as you claim.
 
Time for a READING and LEARNING check.
 
And sorry if you consider it "exuberance". It is just HARD FACTS. Deal.

You would have to plant 37% of all the land in Brazil in sugar cane to produce enough for the vehicles in the USA. Of course we are not going to convert 244 million vehicles to run on ethanol so that is a moot point. I am not sure where you come up with 9 times more energy. A gallon of ethanol produces 76,100 btu/gal whether produced with sugar cane or corn or trees. gasoline is 114,000 btu/gal and diesel #2 produces 129,500 btu/gal. That means to get the same energy out of ethanol as gasoline you have to burn 1.5 gallons. I know you like the stuff and that is fine. I don't believe you have looked at the reality of ethanol as used in the USA. It is a political football. It is purely paybacks from our government to companies like ADM and the mega corn farmers. If the Federal Government really believed it would help our dependence from countries like Saudi Arabia, they would drop the tariff and buy all Brazil could produce. We still produce way more ethanol than Brazil even though it is NOT close to cost effective.
 
PS
The clearing of the rain forest and burning to prepare for growing crops is also environmentally BAD. It will take close to 100 years to mitigate the GHG produced during the clearing of the land for crop use.

That is just not true. Several of us have done the calculated MPG with E10 and pure gas and found the ethanol penalty in fuel economy is very real.

Sorry, but again you are talking without a proper knowledge of the facts
 
The rainforest regions in Brazil harbour a fungus called Mycovellosiella koepkei which inhibits growth: so it´s just pointless to even try to grow sugar cane in the amazon, as you get poor results.
 
Just like there´s another called "vassoura de bruxa" which affects cocoa plantations and only lived in Ecuador.
 
And on the 9 energy thing it´s a WIDELY known fact: google a little.
 
And let me remind you that FLEX ENGINES ARE NOT ETHANOL ENGINES. I DO NOT SUPPORT FLEX ENGINES for the energy reasons you point out.
 
I firmly believe that ethanol is a PROVEN solution and if instead of talking about mileage and other nonsense, if PROPERLY adopted (and not the way it is done) it will SAVE american lives.
 
And I say save because we all know those poor troopers went to Iraq to get more oil.

No, you have NOT.
 
Ethanol requires an ENTIRELY different engine with specs you do NOT have.
 
You just compared it with the same compression ratio and spark timing, and of course got WRONG results.
 
Again: ethanol engines are NOT flex fuel engines.

You are flat out wrong on the subject. The Cars sold in Brazil ARE Flex Fuel.
 
Even Brazilian President Luiz Inacio Lula da Silva has gotten behind the flex-fuel concept, here driving GM's first factory-produced car that runs on gasoline, alcohol or natural gas.
 
SAO PAULO, Brazil — If it wasn’t for the TotalFlex logo on the new Gol subcompacts leaving a sprawling Volkswagen plant, the shiny cars would be indistinguishable from millions already on the road across Latin America.
 
But these Gols and other models produced by Fiat SpA and General Motors Corp. have modified engines that, given the rising price of oil, are making Brazilians smile at the gas pumps. They run on gasoline, alcohol or any combination of the two and now represent nearly 20 percent of the new cars sold in Brazil.
 
With alcohol — also called ethanol — cleaner and selling at half the price of gas in South America’s largest country, Brazilians who have bought 200,000 “flex-fuel” cars since their launch last year say deciding which fuel to use is a no-brainer.

March 8, 2010 in Ethanol
 
10 million FLEX FUEL cars sold in Brazil.
 
Almost all vehicles sold in Brazil are flex-fuel capable (up to 85% ethanol blends, E85) and some are even compatible with 100% ethanol (E100). Every gas station in the country sells E85 and almost all sell E100. This has all been accomplished without government subsidies. As the Brazilian sugarcane organization, UNICA, likes to boast, the industry is completely self sustaining at this point. I’ve written about all this in the past, but as a recap, Brazil’s ethanol success is documented in these statistics:
 
90% of all new automobiles sold are flex-fuel automobiles
100% of GM vehicles produced in Brazil are flex-fuel
 
http://gas2.org/2010/03/08/brazils-10-millionth-ethanol-flex-fuel-vehicle-hits-t- - he-road/
 
If you have any data that refutes the claim that Brazilian cars are Flex Fuel, feel free to post. So far all you have offered is your opinion. Which is fine as long as you can back it up with facts.

As usual you are confusing things by throwing WRONG or UNRELATED data (like this case).
 
Brazil stopped selling PURE ethanol cars in 2007: 86% of the cars being sold today are FLEX and 0% are ethanol.
 
And that´s a HUGE mistake for the reasons I pointed out twice already.
 
That has NOTHING TO DO with ethanol engines being different and BETTER than the flex fuel crap that is available in Brazil and in the US today.
