A simple solution to pain at the pump?
Greener and cheaper, ethanol could fuel rural America — and won't feed Mideast terrorism

This report aired Dateline Sunday, May 7
Pain at the pump is the price of this country’s addiction to oil. Americans are feeling it intensely—outraged over oil company profits, fearful that another hurricane in the gulf, or a terror attack in the Middle East is all it would take to send prices even higher.
But what if there was one solution to all of this? Something that could solve AmericaÂ’s energy crisis, strengthen our national security, and help save the planet at the same time?
Vinod Khosla: I looked, did my research and found this was brain dead simple to do.
Stone Phillips, Dateline anchor: Is it going to mean spending less at the pump?
Khosla: Absolutely. The consumer would be paying a dollar a gallon or less.
At age 51, Vinod Khosla is one of the worldÂ’s most successful venture capitalists and a self-made multibillionaire.
He came to the U.S. from India in 1976, and over the next 25 years, is said to have created six new jobs for every day heÂ’d been in the country. Though not a household name, Khosla was a co-founder of Sun Microsystems and renowned in business circles for his meticulous research and ability to spot the kind of innovative technology that can revolutionize an industry.
Three years ago, he turned his attention to alternative fuels.
Khosla: What could be better than a greener fuel thatÂ’s cheaper for consumers, that doesnÂ’t feed Mideast terrorism, yet instead fuels rural America?
He’s talking about a new generation of ethanol— the fuel made from plants. It’s one fuel he says is just around the corner and will deliver 4 to 10 times the energy of today’s corn ethanol. Khosla knows, because he’s talked to top scientists, visited labs and he’s a bio-medical engineer himself. He believes this new ethanol can replace gasoline and eliminate America’s dependence on foreign oil.
Phillips: How long before you believe this country could be energy independent if it switched to homegrown bushels instead of imported barrels?
Khosla: I think youÂ’ll be surprised by my answer. In less than five years, we can irreversibly start a path that can get us independent of petroleum.
Phillips: What convinced you this was a must for America?
Khosla: I heard about Brazil. I heard they were already doing it. BrazilÂ’s proven it already. How dumb can we be? Sao Paulo, Brazil is a sprawling city of 18 million people. Late last month, we flew there with Khosla to see what a country transformed by ethanol looks like.
Phillips: This has you pretty charged up, doesnÂ’t it?
Khosla: It is very exciting. Here, ethanol is just part of life. ItÂ’s sold at every gas station, including some with very familiar names. Consumers canÂ’t get enough.
Brazil’s been committed to ethanol for 30 years, but if you want to know how it became such a hot commodity lately, start by looking for this label: “flex”. It means cars can run on gas or ethanol. The key to ethanol’s popularity here in Brazil is choice. If you drive a flex-fuel car, you get to choose every time you pull up to the pump.
The choices are gasoline, ethanol—or alcohol as they call it there, or a mixture of the two. You check the prices and make your choice.
Most drivers here choose ethanol, because itÂ’s so much cheaper that even though they get fewer miles to the gallon, it still saves them money.
The flex-fuel cars that triggered the ethanol boom were introduced here three years ago. Already, three of every four new cars sold have the technology.
And whoÂ’s helping to feed BrazilÂ’s flex-fuel fever? American car makers like GM and Ford.
Barry Engle, president of Ford Brazil: 70 percent of a particular model is sold with the flex engine. And 90 days from now it will be 100 percent.
Barry Engle is the president of Ford Brazil.
Engle: This isnÂ’t science fiction, this is real world technology that weÂ’re using in Brazil everyday on a broad scale basis.
At a time when ford and other U.S. automakers are posting huge losses, sales in Brazil are up.
Phillips: Are you telling your fellow executives up in Detroit, "Get more flex-fuel, this is the future?" Has that been the message that you feel like youÂ’ve been bringing?Engle: Yes. There is already, in Detroit, a lot of interest in this particular technology.
In fact, both Ford and GM already sell flex cars in the U.S. And how much more does this new technology add to the sticker price? Not a dime.
Phillips: This is not an expensive proposition for automobile makers.Engle: No. It doesnÂ’t have to be. Phillips: And thereÂ’s no reason it canÂ’t be translated elsewhere?
Engle: As long as the fuel is available.
In Brazil, that fuel is plentiful thanks to a crop as sweet as candy— sugar cane.
Brazil is turning sugar cane into the equivalent of 300,000 barrels of oil a day. To people in this country, what youÂ’re looking at is a field of dreams: Homegrown security that has helped this country to completely free itself from foreign oil.
Last month, Brazil announced it no longer has to import oil from the Middle East or anywhere else. And much of the credit goes to ethanol.
The world's largest sugar cane mill is located in Barra Bonita, Brazil, producing more than 100 million gallons of ethanol a year.
After the cane is harvested, by hand or machine, the stalks are fed into the mill. TheyÂ’re crushed. The juice separated and sent to tanks to ferment. Ethanol operations are really just industrial-sized moonshine stills. Khosla sampled the product straight from tank.
But what really intoxicates him isnÂ’t what he tasted, but the opportunity he sees in whatÂ’s being thrown away. With new technology, Khosla says you can process these mountains of leftovers and triple the amount of ethanol you get, dramatically reducing costs.
Khosla: My bet is itÂ’d be a lot cheaper than $1 a gallon. It might even be less than 70 cents a gallon right there. Right today.
And that’s exactly Khosla’s vision for America— putting new generation ethanol plants next to paper mills, turning their leftovers into fuel. Or even next to orange juice factories, where he says ethanol from peels could replace petroleum.
But thatÂ’s only part of it. To really make America an ethanol nation, Khosla says billions of gallons will come from something as common as prairie grass. He says itÂ’ll be much cheaper and deliver 10 times the energy it takes to make it.
Khosla: We could return the country back to the prairie grass that it used to have hundreds of years ago and make, and meet all our petroleum needs.
Phillips: Back to the future?
Khosla: Back to the future. There is nothing standing in the way.
He’s so sure about it he’s become an ethanol evangelist— preaching to governors, senators and even key advisors to the president who despite his roots in Texas oil is sounding like one of the converted.
In his April 25th speech, President Bush said, “Ethanol will replace gasoline consumption. Ethanol is good for the whole country.”
Khosla: The environmentalists love it because itÂ’s greener. The neo-conservatives like it because it ensures energy independence and security for America. The farmers love it because it takes oil dollars and moves it to rural America.
Phillips: It sounds almost too good to be true.
Khosla: I’m not this “imagine some kind of hypothetical future” kind of person. But it is a very pragmatic vision.
He may be man of vision but KhoslaÂ’s under no illusions about the resistance ethanol faces back home from big oil.
Some oil companies have complained that putting ethanol at their stations would require costly and complicated changes to their trucks, tanks and pumps.
Phillips: How much of a burden will that put on oil companies to start distributing ethanol? To dedicate a pump to ethanol? I mean what about trucks? What about their holding tanks?
Khosla: In most cases, the same holding tanks can be used. The same trucks can be used to transport the ethanol. There are logistics problems to be solved, to be sure, but itÂ’s not a difficult transition. IÂ’ve looked at all the issues they raise. In fact, most of them are bogus.
As for the expense, Khosla estimates it would cost about $15 to 20 million to offer ethanol pumps at a thousand gas stations in California.
Khosla: $15 to 20 million dollars. Exxon alone made 36 billion dollars last year.
But Khosla, whoÂ’s invested millions of his own money in companies working on ethanol technology, says government must play a role as well, by requiring that gas stations everywhere offer ethanol, that all new cars be flex-fuel, and that oil companies play fair.
Khosla: We need to make sure that the major oil companies donÂ’t manipulate the price of oil enough to drive ethanol out of business.
Phillips: Do you believe oil companies would deliberately drop the price of oil?
Khosla: Absolutely. A senior executive of a major oil company came up to me and said, “Be careful.” In a very warning tone he said, “Be careful, we can drop the price of gasoline.”
The battle to bring ethanol to your neighborhood pump is just beginning, but Vinod Khosla is confident that time and technology are on his side.
Phillips: What do you say to skeptics, who say, youÂ’re a money maker, youÂ’re an investor and what youÂ’re trying to do here is to drum up support and governmental help to make sure your investment pays off?
Khosla: Well, I am in the business of investing. But in fact, this has become a mission for me: to get the message out of how simple it is to get independent of petroleum. In fact, my mission now is to put the fossil in fossil fuels.
President Bush is expected to meet later this month with the heads of the Big Three American automakers and ethanol will top the agenda. Wal-Mart has also confirmed to Dateline that it's working out details to sell a fuel that's 85 percent ethanol at its retail locations that sell gas.

I don't know if ethenol is a silver-bullet answer, but it's worth a shot anyways.
There is an E-85 station down the street from my house. Fuel is about .75/gal cheaper than regular unleaded.

Had to run the numbers....
The Ethanol Math
US produces 4 billion gallons per year of ethanol. U.S. ethanol production is projected to reach 8 billion gallons annually by 2012.
US consumes 135 billion gallons of gasoline per year with 1.5% growth/yr.
In 2012, at 1.5% growth, the US will consume 148 billion gallons/day.
8 billion gallons of ethanol is equal to 1.2 billion gallons of gasoline (6.8 to 1 net energy production ratio) or less than 1% of projected gasoline consumption in 2012.
USDA data ~ EROEI = 1.34 to 1 ─ So you must make 3.8 gal to produce 1 gal net.
Ethanol has less energy (energy density) per gallon, so you must produce 1.8 gallons of ethanol to replace the energy in 1 gallon of gas.
Energy density: Gasoline = 45 MJ/kg Ethanol = 25 MJ/kg 45/25= 1.8
So to replace a gallon of gas, you must produce 6.8 gallons [3.8×1.8] of ethanol to replace the energy in 1 gallon of gasoline.
Growing corn and producing ethanol are both subsidized, so replacing 1 gallon of gas costs all the subsidies on 6.8 gallons of ethanol.
Government subsidies on ethanol are about 51¢/gallon, subsidies for corn are $0.375/bushel. Corn to ethanol is 2.5 gal/bushel = 15¢/gal, thus, the cost of taxpayer ethanol/corn subsidies to replace 1 gallon of gas = 6.8 x $.66 =$4.49.
Wholesale ethanol is $2.75/gallon $2.75 + $4.49 ethanol/corn subsidy = $7.24/gallon for ethanol.
And this assumes an EROEI>1
Many studies show an EROEI<1
END RESULT = Ethanol will make a few investors wealthy for a very short time.
Don't Believe the Hype.....
Ethanol is a false promise.
RIO DE JANEIRO, Brazil - Brazil's booming ethanol industry has won international acclaim, but recent supply and pricing problems suggest that it's not the grand solution to tight oil supplies and ever-rising prices that had been hoped.
Brazilian ethanol producers are struggling to keep up with domestic demand for ethanol, which is projected to grow by 50 percent over the next five years. Yet a 15 percent jump in prices earlier this year sparked a sharp drop in consumption. Even so, suppliers are struggling to plant enough fields of new sugar cane, from which ethanol is produced here, to keep up with the anticipated growth in demand.
Some energy experts say this has revealed the limits of Brazil's ethanol program and that it is an unreliable energy source, one that can't be depended on to make much of a dent in worldwide use of fossil fuels.
"Here is the classic dilemma of biofuels," said Tad Patzek, geoengineering professor and biofuels expert at the University of California at Berkeley. "They fight for space in the environment, they fight food production and they fight consumption trends. They are not the answer to the energy crisis."
Such hard lessons come as unwelcome news for U.S. consumers, who are encountering record high prices at the gas pump and threats to oil supplies in politically troubled countries.
In his State of the Union address in January, President Bush asked Americans to look toward alternative fuels such as ethanol as a way out of their energy crunch.
Yet if Brazil is hitting bumps on the ethanol road, Americans, who consume more than 10 times as much oil as Brazilians, face a minefield.
Replacing a year's worth of U.S. gasoline consumption with sugar cane-based ethanol would require a swath of farmland a little smaller than California. Replacing that gasoline with less efficient corn-based ethanol, which the United States produces lots of, would require farmland the size of Texas.
"Biofuels will not make any kind of impact on Americans, the way they're consuming now," Patzek said.

Allow me to retort...
E85 is a blend of 85 percent ethanol and 15 percent gasoline. ItÂ’s not being distributed nationwide yet, but the number of outlets is growing steadily.
Like any alcohol-based fuel, youÂ’ll need to re-jet for the increased quantity of fuel youÂ’ll need to run. Also, timing adjustments may have to be made to account for the slower burn rate of ethanol when compared to gasoline, but for most owners of pre-smog cars, thatÂ’s about it. The fifteen-percent gasoline mix makes starting easy and provides ample lubrication for valves and fuel system parts. The ample alcohol content makes sure those same fuel system components stay clean and donÂ’t get gummed up with residue.
Phil Lampert, Executive Director of the National Ethanol Vehicle Coalition, explains
“We take the corn mixture and remove the starch. We then mix the starch with an enzyme (yeast), and produce alcohol. It’s a simple process, just like the illegal stills back in the prohibition era.”
If weÂ’re using corn as the basis for this fuel, who misses out on the corn? Corn feed for livestock was the primary source, so we asked if this meant livestock feed prices would go up, or if American farmers would have to produce more corn? We liked his answers to both sides of this question, too.
“The mash stillage (corn gluten meal) contains 100 percent of the protein, mineral, and vitamins that were in the original corn, and can be fed to livestock after we’re done getting the starch out of it. Nothing is wasted, and the quality of the feed products is not compromised. It’s a win-win situation.”
What about the need to grow more corn to compensate for the increased need, maybe even in the future, for corn to produce ethanol?
“Well, 10 billion bushels of corn were grown in the U.S. last year. 6 billion bushels of that was used for feed. About 2.5 gallons of ethanol can be made from each bushel of corn. We’re adding value to something that is otherwise wasted. This is a renewable fuel product. We don’t need to expand the growth corn from coast to coast to do this. It’s already here.”
“Even other farmed crops (like rice) grow straw on their fields in the off-season. This straw was once burned, but that’s illegal now. So, farmers began taking it to landfills just to dispose of it; now we can make alcohol out of it. With things like this straw, or even wood waste, we’re adding value where there was none before.”
What is necessary to convert an older, pre-smog era American car (like a Â’60s-era musclecar) to run on E85? Many of the original gaskets, rubbers, and polymers made in the musclecar era are not engineered to handle alcohol. However, if youÂ’ve got a rebuilt engine, you should be fine, especially if you used top-quality gaskets when you rebuilt it.
Regarding the fuel tank (one of the largest investments for upgrading a late-model vehicle to run on E85), the classic cars all have steel tanks, so running alcohol-based fuel is no problem. Aluminum or plastic tanks are not compatible with E85, but you can still run aluminum tanks if theyÂ’re coated internally. For the majority of older American cars with steel tanks, we only recommend you look over the entire fuel system. If youÂ’ve got new lines, seals, and gaskets in your fuel system, E85 should not be a problem.
So, why havenÂ’t we seen this on every street corner in America? Again, we asked Phil. His response makes good sense.
“The oil companies aren’t really supporting this, and it’s not hard to understand. This product has the potential to cut into their sales by about 85 percent! So, we’re working with independently-owned stations where they are willing to dedicate a pump to E85.
This technology is showing up in new cars, too. We found a bunch of information on FordÂ’s website about it, and their flexible fuel vehicles (FFVs) are able to run any mix of ethanol or gasoline. The computer can determine the percentage of alcohol in the gasoline, and will automatically tune the engineÂ’s fuel and ignition curves to compensate for any potential mix.
The use of E-85 reduces carbon dioxide emissions from vehicles by as much as 20 percent, compared to gasoline, and may help reduce emission of greenhouse gases.
The bottom line here is that weÂ’ve finally got something to be happy about when discussing fuel for our high horsepower addictions. We might no longer have to pay high prices for good gas, keep 55-gallon drums stored, or stoop to low compression to run low-octane gas. We wonÂ’t have to hear flak from environmentalists about how our cars are destroying the earth we live on, and we could help our great country take steps toward loosening the noose the Middle East has around our oil-hungry necks.
Jeff Lorch is an engineer from Minnesota focusing on using E85 in performance applications.
“My interest in ethanol stems from growing up on a Minnesota farm. The idea of using a renewable fuel produced from corn was very exciting. I gathered all available information on ethanol, and what I learned solidified the prospect of an ethanol blend being the high performance fuel of the future.
“We’ve been working on a ’69 Mach 1 Mustang. Our objective was to build a “Flex Fuel” engine that would run primarily on E85, but could also use premium pump gas. In addition, I use a 400 hp nitrous plate system, however special consideration MUST be taken when tuning nitrous on E85. A safe target nitrous/E85 ratio is 3.5:1. All stated power numbers are for the engine without nitrous.”
“On a dedicated E85 engine, compression ratios of 12:1-13:1 are likely to take advantage of the higher octane. However, to be able to use both E85 and premium pump gas, we chose 10.7:1 for a safe compression ratio in this FE-based combination. The engine buildup was the same as any high performance street/strip application.”
“Once complete, the engine was first dyno tuned on 93-octane pump gas. We found peak performance to be with 38 degrees of timing and with the fuel jet diameters at .112-inch front and .101-inch rear. The optimum air/fuel ratio was 13.5:1. This combination made 492 lb/ft of torque at 4,500 rpm and 495 hp at 5,900 rpm.”
“We then switched to E85, where we found peak performance at 42 degrees of timing and with the fuel jet diameters at .149-inch front and .149-inch rear. This made 487 lb/ft of torque at 4,700 rpm and 501 hp at 5,900 rpm. Here, the optimum A/F ratio was 10.5:1. This particular engine combination required an average jet diameter increase of 40 percent. This may be on the high end, but was required to compensate for a lower booster signal.”
With regard to hot rodding, the richer mixture should help with evaporative cooling of the fuel-air charge, especially if thereÂ’s a Roots blower whipping it up.
If you want to learn more about E85, we’d highly suggest typing “E85 fuel” into your favorite Internet search engine. There is plenty of great information out there regarding this fuel, and if we hot rodders can get behind this product and encourage its distribution and use, we would only be helping ourselves.
E85 can be used in many late-model applications, with many more coming to market each year. If your vehicle has an FFV logo, youÂ’re ready to go.

Dave Bennett is a Pontiac enthusiast from Minnesota, and wanted to run his 421-powered ’64 Bonneville street/strip car with high compression. “I switched over a year ago from running race gas to E-85, in a 12.8:1 Edelbrock aluminum headed 421ci engine that is used on both the street and strip. On the dyno, we found the ideal air/fuel ratio for E-85 was 10:1, and the engine made 596 hp and 598 ft. lbs. It runs as cool as a cucumber. The only "hitch" I've had so far is getting the carbs tuned right in the mid-range, but this would be a cinch with EFI. The mileage is off, but considering the price for E-85, it can be off a lot compared to $3.50 a gallon for leaded 110 race gas.” Dave’s best ¼-mile elapsed time to date is 11.42 at 124 mph. That might not seem too fast for a high-compression motor, but remember this car is no lightweight, checking in at way over 4,000 lbs. We asked Bennett how he felt about the future of E85 “I would go out on a limb and predict that E-85 is the "race gas" of the future (within 5 years) - others in our area have "discovered" it. Four or five other guys were running it at the drag strip this summer, and the circle track guys are starting to use it - after all, it's "pump gas". During my dyno pulls, my intake manifold temperature was 40 degrees F.” How much additional jetting would a classic 421 Tri-Power require? “After I made the switch, another one of the guys in our local club converted over with a vintage high-compression (13:1) 421 with tri-power. He ended up in the mid-90's for jet sizes in all three carbs- not on a dyno, but just by "shade tree" tuning. Once he got it jetted in the ballpark, he became a believer. Unlike gasoline, you can run on the fat side with ethanol without a big horsepower drop up in the higher rpm ranges.”

If you do the math, no way could we just up and go alky in everything... but, it is an alternative to buying some of our oil from overseas, it's renewable, and we have lots of empty farm land sitting unused.

The problems with Ethanol is that it will damage certain types of fiberglass, plastics, epoxy etc. I have also been told that it is caustic to aluminum. I would worry about what it will do to fuel system in you vehicles.
I will not put any fuel with Ethanol in it in my Skater because it has epoxy coated tanks and they have already had problems with it destroying the tanks. Sounds like it might be the next MTBE. Something to think about. :cool:

Next MTBE that's a little harsh IMHO. Damaging your motor and giving you cancer from your water sound about 180 degrees out. Your not in oil are you. :rolleyes:
