damage from ethanol?
Someone in a country other than the USA has done a study of the
effects of 20% ethanol/80% gasoline on engines by running a weedwacker and an outboard motor on such a mixture. He reports: "The study of ethanol's impact on engines found the 10 per cent blend caused no substantial changes, except slight swelling and blistering on the carburettor and an increase in carbon deposits on pistons. But when the fuel contained 20 per cent ethanol, substantial problems were encountered. The outboard engine stalled on occasions, exhaust gas temperature increased by a significant margin and in some cases there was extensive corrosion of engine parts." Could someone list all the reasons this is not a good test. (I suspect you'll all think of some of the same things, so maybe look at previous answers before answering.) Any reasons it is a good test are also appreciated. |

This is nothing new. This was more an issue for older cars when ethanol was
first blended in, but that was years ago. In Illinois everything has been an ethanol blend (10% I think) for years. If the engine and parts are built right, you can run 85% ethanol. I think a lot of cars coming off the line today can handle it. But a weedwacker and a boat engine are probably just not designed for that much ethanol in the mix. S |

I would still like to see a valid study showing that ethanol is a valid alternative to gasoline. There are knowledgeable individuals that state that it takes more energy to produce it than we get out. Therefore may be nothing more than a subsidy to the farmers. Mostly I hear "political babble" by people that know nothing of the subject. |

They sell more ethanol than gasoline, and 70% of the cars sold last year will run on 100^ gasoline or 100% ethanol or anything in between. (Mrsgator probably knows that they they make it from sugar cane. If our cars burned ethanol also, maybe we could import that from Brazil or somewhere else, or we could import the sugar cane, or we could load the ship with mash and let it ferment on the way to the US.) Ethanol is physically inferior and more costly than gasoline. Prices change. Gas is 3 dollars a gallon now. How much will it be 2 years, 10 years from now, after China and India want to buy even more. And they aren't going to be the last countries that expand their demand. How much will it be after some oil fields dry up? The support for it is political, and not just the farmers.

We're not dependent on it? By that logic, we are better off burning domestic candles than importing sunlight: How does one import sunlight? Furthermore, unless we want shorter nights, we have enough sunlight already. http://bastiat.org/en/petition.html I think instead of imagining this is all politics, we should take note of the fact that support our prejudices and the ones that contradict them. |

And maybe the net energy balance for sugar cane to ethanol is better than corn to ethanol? More fermentable sugar from x lbs. of sugar cane plant than from x lbs of corn plant? I know you can just chop off a random hunk of sugar cane and chew on it to get sugar, and that sure doesn't work with a corn stalk. |

Talk to someone who's invested in a fuel ethanol plant. Ask them what kind
of profits the plant is generating. Even if you tax the fuel ethanol the same as you tax gasoline, it can be produced at a considerably lower cost than gasoline can be produced and marketed from $50 crude, let alone $70 crude. Brazil will have a hard time making inroads into the fuel ethanol markets in the interior parts of the U.S. because of transportation costs. They can have an impact near the costal areas. Most of the fuel ethanol in the U.S. is produced in the Midwest, the corn belt. The further you have to transport from the Midwest, the less competitive it becomes. California, for example, imports a lot of fuel ethanol at relatively high cost, primarily because of the environmental benefits of mixing it with gasoline and the fact that they don't have the right crops to produce it themselves. The oil companies do not favor fuel ethanol (or any other bio-fuel, for that matter). I wonder why, although I suspect I already know the answer. The oil industry has been consolidating for a number of years. They've managed to reduce the number of refineries to the point that they just have enough refinery capacity to meet current demand (note what happened to gasoline prices when Katrina took refinery capacity off line). Any large scale fuel ethanol production will upset their delicate balance and bring more competition to the oil industry. Obviously, not something they want to see, considering the amounts of profits they are enjoying under the current conditions. For now, corn is the most feasible material to use for fuel ethanol production in this country. And, by the way, the corn is not lost as an animal feed just because it's been used to produce fuel ethanol. The primary byproduct of a fuel ethanol plant is a dried distillers grain, which is a high protein animal feed. A lot of work is being done to develop processes to economically produce fuel ethanol from biomass/cellulose, i.e., sawdust and such. If that happens (and it will eventually), watch what fuel ethanol does. Coal fired fuel ethanol plants that meet all environmental requirements are being built today. If crude prices stay above $35 dollars a barrel, the fuel ethanol plants will do fine. We need to let the marketplace decide if fuel ethanol is feasible. Harry "Richard J Kinch" wrote in message .. .

However, I would like to see a current valid study that shows that ethanol can be produced for those low prices. So many that I see are quite old and it seems to me that most are just reporters making guesses. Since ethanol must be shipped by rail it presently becomes very expensive in many parts of the country. http://zfacts.com/p/60.html |

Bunk. Photosynthesis is inherently weak and wasteful. Ethanol is a technically inferior fuel. The justification is more or less, "we may lose money on every gallon, but we'll make it up on volume". When compared to gasoline, you won't get an argument that ethanol can't give you the energy output that gasoline can. But, it does have sufficient energy output to drive a vehicle and, when added in amounts around 10%, ethanol has beneficial environmental effects and the mix is not as energy inefficient as pure ethanol because of the improved burning of the gasoline portion of the mix. Nature, left to it's own devices, came up with a fantastic process to capture energy from the sunlight. We've been deriving benefits from that process for years as we pump crude oil from the ground, crude oil that the photosynthetic process enabled natural earth processes to store away. Eventually, that storehouse will be depleted. Can we replace it with some renewable fuel source? We'd better be able to. Will it be fuel ethanol derived from grain? Definitely not completely. Could it be fuel ethanol derived from cellulosic materials? Yes, if that process is sufficiently perfected. More likely, it will be replaced by a mix of technologies. There's a lot of concern that the use of corn for manufacturing fuel ethanol primarily benefits the corn producer. I think that the folks who voice this concern miss that fact that every form of energy that we use benefits some more that others, i.e., OPEC, the crude producers, drilling equipment manufacturers and the people who drill wells, oil companies, coal producers, natural gas suppliers, electricity producers, and on and on. You can bet that the fuel ethanol plants currently operating aren't losing money. Those on the drawing boards, and there are a considerable number planned, will never be built if it looks like they'll lose money. Again, let the marketplace decide if it's weak and wasteful. The marketplace in this country is very efficient at ferreting out inefficient processes. Harry |

Mostly I hear "political babble" by people that know nothing of the subject. Ethanol production from corn barely breaks even on energy balance, provided you squeeze every bit of energy out of the entire process. Burn the waste stalks, roots, etc. and capture that heat; capture the heat from distillation rather than let it waste; etc. etc. The reason being that modern agricultural is so hugely dependent on ammonium nitrate fertilizer, and ammonium nitrate fertilizer is made by consuming huge amounts of energy. Without that, you couldn't get 10% of the yield of corn you do now. Sugar to ethanol production seems to be more efficient, at least in big sugar cane producing countries, I don't know if it would work in the US; Brazil had been pushing to sell cheap ethanol fuel to the US for years but was prevented by tariffs, etc.; but now they have hit a point where they can no longer produce enough for their own needs. Ethanol as a fuel works pretty well, with a few problems; as you note, materials have to be ensured to be ethanol resistant, which is not always the case with gasoline engines. Also, ethanol can carry a lot of water along with it, so corrosion can be a problem unless specifically designed to withstand it. Ethanol has 1/2 the energy content of gasoline, so you get only 1/2 the mpg, and carburetors, injectors, etc. have to be designed to flow twice the fuel. Since you can't tailor the vapor pressure of ethanol the way you can with gasoline, which is a mixture of various volatilities, starting with ethanol fuel on a cold day is basically impossible; you need to either heat the engine or use some start of starting fluid until the engine has heated itself. Also, if you've stood around ethanol burning race cars, the exhaust is frigging awful, it makes your eyes water. I think it's formaldehyde in the exhaust, but I may be wrong. However, I assume catalytic converters might fix that? On the up side, ethanol has a high octane rating and will allow high compression, and also burns very cool so that high performance can be achieved without risk of destroying the engine. Both reasons why it is so popular in some race series, even though it only delivers half the energy. |

It seems most estimates come in the range of it taking 3/4 to 1.25 (sometimes up to 3)gallons of gas or diesel to produce a gallon of ethanol, & the most favorable studies show it a wash AT BEST. THEN you have to figure in the lower energy of ethanol on top of that... a 28 mpg(on gas - highway) Taurus(Taurus FFV - the ones with the little green leaf front fender badges) becomes something like 20 mpg on E85(15% gas, 85% ethanol). It's been a while since I've done it, but you can do a web search for "E85 Taurus" to get some of the empirical data from these tests. Rob |

For many weedwackers, the test makes sense. If they run 90% gas and
105 ethanol, they've left out the oil. What's the mix, 1:32? If so, you should have about 3% oil. Shouldn't the mix be 9.7% eth, 3.1% oil and 87.2% gas? Am I being too literal (and cynical) here? Never underestimate the ability to make a study say what you want. |

Our OIL driven economy is being held hostage to the middle eastern
dictators. terrorists dont like us because we meddle there So I say build the plants and convert the cars as fast as possible, and let them drown in their own oil.... growing corn or vegetable waste for conversion into ethanol might help reduce global warming, as the plants clean the air. Ih yeah make all ethanol TOTALLY TAX FREE FOR 10 YEARS TO ENCOURAGE THE CONVERSION! just this alone will save about 50 cents a gallon on the pump price |

But when the fuel contained 20 per cent ethanol, substantial problems were encountered. The outboard engine stalled on occasions, exhaust gas temperature increased by a significant margin and in some cases there was extensive corrosion of engine parts." Could someone list all the reasons this is not a good test. But it is a good test. It is a good test of what happens to certain weedwackers and outboard motors. That is all that it covers. If you want to know what happens in an automotive engine, you have to test it in that engine. There are a lot of differences. (I suspect you'll all think of some of the same things, so maybe look at previous answers before answering.) Any reasons it is a good test are also appreciated. -- Joseph Meehan Dia duit |

i find alot of chainsaws and weedwackers wont restart when hot
because the ethenol/gas boils and wont pump... let em cool and they start and run fine. lucas http://www.minibite.com/america/malone.htm |

I wonder if the OP (mm) expected all this when he asked his question :-)

Brazil is self-suffcient on fuel producing lots of ethanol. U.S. could do it too. and why not?. |

The US, for examples, blocked sugar imports with trade restrictions and a propped-up US price to support US sugar businesses - like sugar beet. Ethanol has to be based on a marginal crop that can grow without intense farming techniques. Otherwise, it will cost more energy to make than to use. Mike |

This is another example of how only a part of the story gets told and how people go off half cocked. Another key point to the Brazil story is they didn't just use Ethanol to become energy independent. Last week there was a picture of the President of Brazil on an offshore oil well, turning the valve on, bringing it online. Yet, if you talk about drilling off shore in most areas of the US, the environmental extremists all come running around telling you it shouldn't be done. Then they point to the wonders of Brazil as an example of how to achieve energy independence, hoping nobody will notice the truth. The reality is we should be pursuing multiple solutions. Opening up more areas to drilling *(ANWAR, offshore, etc), building nukes, ethanol provided it's cost effective, wind, more research on solar, more conservation, etc. But anytime you try to do almost any one of these, some nuts show up to **** and moan and stop it. |

There is no silver bullet, but a lot of smaller changes have some hope of getting us a lot closer to the solution. But anytime you try to do almost any one of these, some nuts show up to **** and moan and stop it. And unfortunately, most people claim these ****ers and moaners are all left-wing environmentalists, In fact, right-wing politicians in the back pockets of special interest groups are just as much of a problem. Mike People claim that the environmental kooks are a problem becauce they are totally unreasonable and opposed to almost everything. No offshore drilling, no nukes, no drilling in ANWAR, no storage sites for nuke waste, no builiding of dams. A classic case of the hypocracy is Robert Kennedy Jr. Big environmentalist telling us all how we should be changing our lives to help the environment, conserve resources and how we should be adopting all these great clean renewable energy sources. But, he sees nothing wrong in personally owning several large SUVs, more than one home and riding in private jets. Currently three is a proposal to build a wind farm off Cape Cod. Who are two of the chief opponents? Kennedy and fellow liberal Walter Cronkite. They know what's good for all of us, they just won't have any part of it for themselves. You can say what you want about right wing Republicans being in the back pockets of special interest groups, but in general, they are not opposed to everything and do want to move ahead on finding more energy, which we ultimately need. All the whacko environmentalists want to do is obstruct everything, including windmills, while many of them like Kennedy, consume resources with abandon. |

According to mm :
Someone in a country other than the USA has done a study of the effects of 20% ethanol/80% gasoline on engines by running a weedwacker and an outboard motor on such a mixture. He reports: "The study of ethanol's impact on engines found the 10 per cent blend caused no substantial changes, except slight swelling and blistering on the carburettor and an increase in carbon deposits on pistons.

Could someone list all the reasons this is not a good test. (I suspect you'll all think of some of the same things, so maybe look at previous answers before answering.) Any reasons it is a good test are also appreciated. Not having seen the report, I'd remark/ask questions on the following: 1) Comparing what are probably two-stroke with oil mixed in is not a fair comparison with a 4 stroke car engine. 2) Where did he get his ethanol from? How much water did it have? This is more likely to be the cause of blistering/corrosion than anything else. 3) Did he retune the engines properly for the different mixes? Increased heating is more suggestive of bad tuning - ethanol should be cooler. 4) Comparing engines that have virtually _no_ consideration of ethanol fuels in their design to engines that do isn't a reasonable test. 5) "Swelling of the carburettor?" A metal carb swelled? I don't think so. Suggestive of plastic (especially nylon) carb parts. Nylon swells when wet with water or alcohol. Engines designed for ethanol should not have nylon in its fuel system. Ethanol works just fine in engines provided that the engine designer has taken a few things into account. For example, one of the things that used to happen is clogged carbs after a car switched from gas to a ethanol blend. You see, if there's water present, the ethanol will pick it up. If the car had a paper fuel filter, the water would cause it to disintegrate, and the paper sludge could plug things up. If you had picked up gas from a tank that just switched to an ethanol blend, there can be an enormous amount of water in it (I'm told that these tanks can sometimes have several inches or more of water in the bottom. Which is only a problem with straight-gas if the gas level is very low and/or recently disturbed. Ethanol will simply suck it all up. They don't make fuel filters that way anymore. -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them. |

You CANT increase production of oil indefinely, it has a finite amount
in the earth, and will only cost more in the future. Its best to move top something produced entirely in the US even if its not a ideal fuel. At least this way we are in charge of our own destiny. Make ethanol gasoline tax free for 10 years to encourage conversion, let the arabs drown in their own oil. |
