No. Now there is a surplus of corn and most other US grain. If a shortage occurs a year from now, it remains to be seen. The market will adjust. As price rises, less corn will be used. Substitution with other grain will reduce corn consumption as well.

The horsepower thing is really simple. One pound of ethanol requires 33% less air to burn than one pound of gasoline. So, at full throttle, a fixed diameter intake will allow over 50% more fuel into the engine. Pound per pound both fuels will produce the about the same amount of combustion byproduct. Gasoline has a slight advantage. Make no mistake, ethanol will develop more hp than gasoline, but you will use more fuel in the process.
In addition, ethanol has a higher octane rating. This means ethanol can be ignited sooner than gasoline can and burn longer at a higher temperature (without knock). More heat during combustion means more transfer of energy to kinetic energy. How far the carmaker allows timing to advance determines how well the engine will use ethanol. In general, the greater the timing advance, the better the fuel economy.

"Ethanol is a great fuel in an engine designed to maximize its value...none of the big 3 offer such an engine"
I would disagree. We purchased a new Chevrolet Tahoe in 2002. We have run mostly E85 through it. We have measured almost every tank of fuel into the vehicle. Under similar driving conditions, the fuel economy is indistinguishable between E85 and gasoline.
I also had the opportunity to speak with the General Motors VP of alternate Fuels a few years ago. He indicated that when running E85 in our Tahoe, the engine would develope an addition 20 hp or more over regular gasoline.
We certainly don't have anything to complain about.

~Doesn't look like you tried very hard. Search this very forum and you will find links to many different studies showing ethanol production is net energy GAIN. You will find exactly ONE study saying it's a net loss (Patzek/Pimental, Cornell University). Regarding your carbs needing cleaning - let gasoline sit around, doesn't matter if there is ethanol in it or not, and it will go bad. -Matt

5150windsurfer ponders "I've tried unsuccessfully to find out if ethanol products are a net gain in energy or not. In other words, does it take more energy to produce ethanol than what the ethanol actually contains."
According to the US Dept. of Energy's Ethanol Myths and Facts site, "Ethanol has a positive energy balance – that is, the energy content of ethanol is greater than the fossil energy used to produce it – and this balance is constantly improving with new technologies". The site says that it takes 0.74 BTUs to make a BTU of ethanol. Comparatively, it takes 1.23 BTUs to make a BTU of gasoline, so gasoline has a negative energy balance.

You are overlooking a fundamental piece of history. While 39% of the corn may be going into ethanol (and animal feed) production, farmers have increased corn production by 40% since 2007. No children have starved in the making of ethanol.

I used to work for a sugar cane growing company and I did a lot of research on ethanol as it can be derived from sugar cane as well as corn. In fact it is seven times more efficient to get it from sugar cane. Brazil gets all of their ethanol from sugar cane as does Australia. At least when I did my research more than five years ago that was the case; i can't say what they are doing tody. I say all of this because my research showed that ethanol from corn is extremely inefficient in fact even getting it from sugar which is so much more efficient was such a risky business that no one wanted to spend the money to build the ethanol conversion plant. Ethanol producers only make money when oil is super expensive and we all know how oil prices go up and down. If ethanol is truly a substitute for gasoline or can at least lower our dependence on foreign oil or any oil for that matter then I am fine with making government subsidies to get the business started. Things like building the conversion plants and paying for first crop seed, stuff like that. But the current system doesn't pay farmers to grow ethanol it just sets high prices for their finished product. So they grow a lot of corn but sell it at high prices for ethanol leaving all of the original corn customers paying high prices for the feedstock needed for chickens, cows etc. which drives up cost throughout the supply chain. The US ethanol program has a lot of flaws. I think it is more to do with political lobbiest from the corn growers than any thing else.

Actually, MTBE reduces fuel economy more than does ethanol. Yes there is phase separation with MTBE fuel. It just happens much sooner with the MTBE fuel. Water enters the fuel system the say way without regard to the type of fuel: heating and cooling of the fuel in a partially fulled tank. Its called condensation.
Farm subsidies in the US have decreased as a result of increased demand for corn.

From the EPA: "However, researchers have limited data about what the health effects may be if a person swallows (ingests) MTBE. EPA's Office of Water has concluded that available data are not adequate to estimate potential health risks of MTBE at low exposure levels in drinking water but that the data support the conclusion that MTBE is a potential human carcinogen at high doses."
It seems the EPA isn't quite so quick to give MTBE a clean bill of health. "As of 2007, researchers have limited data about the health effects of ingestion of MTBE. The United States Environmental Protection Agency (EPA) has concluded that available data are inadequate to quantify health risks of MTBE at low exposure levels in drinking water, but that the data support the conclusion that MTBE is a potential human carcinogen at high doses."
MTBE doesn't cling well to soil, meaning it migrates quickly into underground water sources after a fuel spill. It takes only a small amount to affect the taste. It takes many years for it to start to disappear. It does evaporate quickly from a reservoir, but not from underground sources, such as the aquifers that many places get drinking water from.
So, I guess you would be comfortable serving your family cold drinks with MTBE-laced ice cubes, then?

"MTBE is a carcinogen"
MTBE is NOT a carcinogen.
" The National Toxicology Program (NTP) is formed from parts of several different US government agencies, including the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). Exposures that are thought to be carcinogenic are included in the Report on Carcinogens, published every few years. The NTP has reviewed MTBE and voted not to include it in the lists of compounds known or reasonably anticipated to be human carcinogens.
The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO). Its major goal is to identify causes of cancer. The IARC has concluded that there is inadequate human evidence, and limited animal evidence, for the carcinogenicity of MTBE, leading to an overall evaluation of MTBE as "not classifiable as to its carcinogenicity to humans.""

Where do you get your information from? You need a new source. MTBE is a carcinogen, and polluted a lot of groundwater, no we don't use it in our fuels! In 2001 MTBE poisoning of groundwater was found in every province in Canada. It has been phased out by all Canadian gasoline producers as of a 2004 report. We have E10 in every regular pump in Manitoba. We have no problems, and, as a bonus we don't need to add fuel-line anti-freeze to our tanks in winter, which is expensive bottled alcohol anyway.

"Perhaps it is not a scam but it certainly is a shame! Gasoline diluted with ethanol decreases gas mileage and performance. "
Any reduction in fuel economy depends on the car. Nost people using fuel containing 10% ethanol or less will not be able to detect any difference in fuel economy.
As far as decreases in performance, that doesn't happen. Ethanol produces more horse power than gasoline, in any given engine. The higher the ethanol content, the greater the increase in horse power.
