1) oil companies are sponsoring research to disprove the use of ethanol
Does anyone know if you have to have a licenses to transport unleaded gas?
2) critics love making assumptions that ethanol production isn't positive energy by adding in extra items like irrigation that generally aren't used in most fields.
I live in Central NY. When do you think it's time to take my winter tires off?
3) critics don't believe that supporting ethanol research and production will lead to the development of better fuels such as butanol and other designer alcohols.
Anyone know of a used segway shop in south Florida?
4) critics are short sighted in seeing only the downside of the current instead of the positive posibilities of the future. The government doesn't fund ethanol because it is great now, it is investing in the future.

The ethanol mandate illustrates how environmentalism has become a vehicle for dishing out pork while harming consumers, taxpayers -- and the environment. Although the mandate seems dead for now, it could be revived by Congress, where Senate Majority Leader Robert Dole is a big supporter. The issue will be a test of whether the Republicans are serious about basing environmental policy on sound science.What kind of commute would be worse for a car?
But surely the harmful environmental consequences of oxygenated fuels are outweighed by their usefulness in reducing carbon-monoxide levels? Unfortunately, they don't seem to be doing so. In April 1993, Chemical and Engineering News reported research by a team at the University of Colorado, Denver, on the effects of using oxygenated fuels in Colorado's Front Range area. The oxygenated-fuels program is estimated to have cost the drivers in this area, which includes Denver, Colorado Springs, and Fort Collins, $14 million a year in higher fuel prices alone. Carbon-monoxide levels have fallen, but when a careful statistical analysis takes into account the fact that the automobile stock over the peroid studied changed to one with cleaner-burning engines, the carbon-monoxide drop that can be attributed to oxygenated fuels becomes statistically insignificant. Ambient carbon-monoxide levels had begun to fall well before the use of oxygenated fuels. Thus the TV ads of Archer Daniels Midland (the major producer of ethanol in the United States) hyping the wonders of ethanol in the Denver area should be heavily discounted.
Furthermore, the data suggest that the use of oxygenated fuels may have increased the ambient levels of formaldehyde (a known carcinogen produced by MTBE) in the Front Range area. Data from Albuquerque indicate an increase of atmospheric organic acids because of the use of ethanol. The University of Colorado report agreed with a 1992 report by the Colorado legislature that found "limited benefits" from the use of oxygenated fuels.

In short, there is little evidence that the oxygenated-fuels program is doing any environmental good, or that ethanol is superior to MTBE. To date, the main effects of the oxygenated-fuels program have been increases in taxes, in the cost of gasoline, and in noxious pollutants.
Why do we not tout motorcycles and scooters more?
BUT ethanol has one politically positive attribute: it can be used to subsidize farms. The leading defenders of the ethanol mandate in the Senate, where an attempt to derail it failed last year, are from the Midwest or have logrolling obligations to the grain-producing states. (The mandate went so far as to specify that the ethanol was to be made from nothing but grain, even though ethanol made from water and ethylene in a refinery is chemically identical and can be produced at a fraction of the cost.) Last year's debate was nonpartisan, with Democrats Bill Bradley (N.J.) and J. Bennett Johnston (La.) leading the opposition. Bradley opposed the mandate on environmental and economic grounds, pointing out that ethanol already enjoys a 54-cent-per-gallon subsidy and that the mandate would cost consumers hundreds of millions of dollars a year. A. B. Early, environmental-quality program director for the Sierra Club, argued that the mandate would increase the potential for smog and air toxins.
How can I find the average traffic on a freeway at a certain time?
Ethanol, however, does not seem to be a promising substitute. The reaction of volatile organic compounds, nitrogen oxides, and sunlight is a major cause of smog. Organic compounds are considerably more volatile in gasoline mixed with ethanol than in gasoline mixed with MTBE. Furthermore, ethanol use in automobiles produces acetaldehyde, a precursor to PAN (peroxyacetyl nitrate), which is known to be harmful to plants, as well as a probable cause of cancer. One of the highest PAN levels in the world occurs in Rio de Janeiro because of Brazil's push to use ethanol in automobiles.
Why are anti skid zones on roundabouts always covered in skid marks?
One of the main arguments against ethanol is that you can't produce it at a cost cheap enough at a large enough scale and that it takes more energy to produce the ethanol than the ethanol actually produces. This means that it is a very uneconomic fuel on it's own. It can probably be used as a suppliment to petrol however I doubt it's viability as a fuel in it's own right.We don't hear of road rage so much any more, do you think it is occuring less often?
The reasons someone could be against it are numerable... here are just a few.Have you ever experienced road rage?
The cost to produce ethanol from corn is much higher than what other countries are paying to produce it from sugarcane.
The cost of corn rises and that in turn causes the cost of meat to go up because the farmers have to pay more to feed the cows.
This also causes food prices to go up around the world. The more corn we keep the less we export and substantially reducing this grain export flow would send shock waves throughout the world economy.
When ridesharing / carpooling - How important is a "guaranteed ride home" program to you?
The U.S.'s National Chicken Council reports that the ethanol's demand for corn (around 14% of the country's corn production) has inflated corn prices in such a way that the wholesale price of chicken increased by six% per pound in January
What are the red and white gates that are seen on I-64 exits?
The biggest problem with the use of E85 ethanol is that it's looked upon as a temporary and unrealistic fix. They "claim" that there's no way the U.S. could produce enough corn to make enough E85 ethanol to fuel the number of cars we would need to run on E85 ethanol to really make an impact on our need for oil (of course, the researchers saying this have ties to the big oil companies, so what do you expect them to say?) The other half of the argument is that fuel-cell technology is "expected" to be fully developed and used as the primary fuel source for motor vehicles within the next ten years (but it's the Big Three saying this, and we all know THEY have ties to the big oil companies too). The U.S. should have pushed development of E85 ethanol vehicles after the energy crisis of the 1970's, but the Big Three is not notorious for innovation -- and you wonder why the Japanese are kicking the crap out of us in the world car market...Best GPS for rerouting and regular destinations?
Nobody hates corn and some people like big oil, but there are a lot of other factors.How come after being warned to drive slowly, people drive really fast on rainy days?
Despite all of the problems with oil (like getting it out of countries full of angry arabs or from 10 miles beneath the sea bed), it's actually a cheap form of energy. The only trouble is, there's a limited amount down there and nobody knows just how long it's going to stay cheap. The other problem is that nobody knows exactly what effect increasing CO2 has on the climate (yeah I know lots of people think they're experts). That's another topic - I won't go into now.
What does hov mean on lanes in towns like memph tn.?
One limitations with corn is the investment required to get large scale ethanol production running. Ethanol from fermentation relies on yeast and it ties up the equipment for a long time, compare that with refining gasoline from oil - a refinery can pump out gasoline pretty fast. I think there are only pilot schemes in the US to make ethanol from corn. Most fuel ethanol is synthesized from oil.
American transportation.... money over safety and efficiency?
There just isn't anywhere near enough corn under cultivation to make a big dent in fuel demand. Compare how much corn people eat every day with how much gasoline people use. Big difference isn't there.
I how do i fight a traffic tickets in nyc for a moving volation.?
Another problem is that ethanol doesn't have anywhere near the energy yield of gasoline, so you need a lot more ethanol than gasoline to power a car.
What do you hate the most ...?
Someone estimated that if the entire agricultural capacity of the USA was turned over to ethanol production for motor use, there would still not be enough. What makes it worse is that producing EtOH from starch crops or even sugar consumes a lot of energy. The energy balace may be positive, but it may also be negative. Probably depends on exactly what process you use.How much money is gas in Kamloops, BC?
For the present E15 is probably a good fuel because most cars can handle it with ease, though I find that even E10 makes the fuel pumps in my car noisy.
How do I calculate mileage rate (reimbursement) for driving my car for work?
You will probably get a better energy balance from biodiesel or straight vegetable oil, either mixed with petro-diesel fuel, or on it's own.
Why are most man holes smack in the middle of a street?
Lot of drivers in Australia have converted to liquified petroleum gas, (LPG) specially high mileage drivers like taxis and other town runabouts. The still maintain their petrol tanks though.
Any suggestions regarding rental trucks for moving across states?
The problem with ethanol is production vs cost. Currently (after watching a show on the Discovery channel), corn will only produce a return of 6 barrels per acre (this is after planting, irrigation, harvest, and processing), but a return of 600 barrels per 100 acres is not cost effective. Sugar cane will only produce a return of 8 barrels per acre, which also makes this crop prohibitive in cost of production. The only crop which makes sense is Prairie Grass, which will produce a return of 16 barrels per acre, per harvest. Prairie Grass can be harvested up to 3 times per year. Sugar cane takes two years to grow, and corn is an annual crop. So do the math.Uh oh, here come the flat-earthers, i.e. the "global warming isn't happening" ostriches. Okay, have your SUVs.
One valid point I've heard is that ethanol requires a lot of energy to produce; you must *distill* the stuff by boiling and condensation. So what? The same is true of gasoline and diesel; that's what happens inside a refinery fractioning column.

What is the max weight a Segway can use before it fails to move?
In my opinion a better answer is biodiesel/SVO (straight vegetable oil). SVO can be used straight in a modified engine. Or ANY engine can run biodiesel, and the biodiesel modification is very low energy, needing only heating to 130ºF. Also, SVO is readily available to anyone right now; last I looked, CostCo had it for $2.59/gal. in 5-gal. fryer packs.
How long does it take to drive one mile at 65mph in seconds? 75mph?
they do not know what it is. or that it gives you more hp. because it burns faster and you would use less. and that any car can run it. mostly because they think its a aditive which most people think are just gimicks.More Questions & Answers ...
