Aside from showing support for the farmers, at $3 a gallon, how long will (VERY FEW) people show support for them at the pump when E-85 kicks a dent in overall mileage. Less miles per gallon for fuel that is rarely any cheaper than gas??? And ... not a single word in here about any environmental benefits via tailpipe emissions. More than likely, there are no big environmental benefits via tailpipe emissions or it would have been touted.

Hybrids are too flimsy and expensive (even with the tax credits). Takes years to recover the added cost of buying a hybrid and it still uses the gas motor full-time when driving above 35mph or below 35mph with a/c or heat running.

Diesels perform well, aren't environmentally unfriendly when you take into account the high miles per gallon (use less gas to travel greater distance) and even when diesel costs more per gallon than gas, you still get more distance from a tank, reducing the actual cost.

What rainbow is everyone chasing with hybrids and E-85? The answers are obvious. Chrysler and MB are going to be the only ones whose alternative technologies (via modern diesels) stand the test of time.

Read on ... This was pulled from today's NY Times.

"Fill Up on Corn if You Can"

SPRINGFIELD, Ill. — Standing next to his pickup truck at a service station here, Robert Beck squeezed a yellow nozzle and filled up with the corn-based fuel blend of 85 percent ethanol and 15 percent gasoline that car companies, farmers and politicians alike love to promote as a way out of America’s oil addiction.

Mr. Beck, an agronomist who travels throughout the Midwest, likes the idea of E-85, as the fuel blend is known, because it is made mostly from a domestic crop. But he still finds that buying the fuel is almost more trouble than it is worth.

“Everyone talks about it, but exactly where is it?” he said. “You have to have more fuel out there for consumers to buy.’’

That could take a while.

To assess just how efforts to help E-85 catch on were going, a New York Times reporter, accompanied part of the time by a photographer, drove through the region where its popularity is greatest. They found that despite all the good will toward ethanol, success is far from assured.

The fuel does have plenty of powerful supporters. General Motors used the Super Bowl this year to kick off its “Live Green, Go Yellow” campaign to encourage Americans to buy vehicles that can run on either E-85 or conventional gasoline. Ford Motor and VeraSun Energy, the second-largest ethanol producer after Archer Daniels Midland, christened 300 miles of highway from Chicago to St. Louis the “Midwest Ethanol Corridor” in a marketing campaign that began in June.

But it also has plenty of drawbacks. Most oil companies want nothing to do with E-85, which they see as a money-losing alternative to their own petroleum-based products. Without help from the oil industry or a lot more flexible-fuel cars on the road, gasoline retailers are hesitant to install the expensive pumps, which can cost up to $200,000 with a new underground storage tank.

“There is no way E-85 can survive on its own without massive government subsidies at the state and federal levels,’’ said Lawrence J. Goldstein, president of the Petroleum Industry Research Foundation, an energy consultancy in New York.

Many drivers whose vehicles can run on ethanol will not buy E-85 unless it is markedly cheaper than regular gasoline, which has not always been the case. Part of the reason is basic economics: E-85 delivers only three-quarters as much energy per gallon as gasoline, meaning drivers will have to fill up their tanks more often if they choose to use the fuel.

More than 850 service stations now carry E-85, an increase from 350 since the beginning of 2005, but the fuel is still unavailable at most of the 169,000 stations in the United States. Sales are so slim that some retailers count their regular E-85 customers on one hand.

Customers like Mr. Beck, who want the fuel, struggle to find it: in Illinois, 135 stations carry it, but in neighboring Missouri only 54 stations have E-85 pumps. Kansas has 13.

None of this has discouraged E-85’s supporters, who are relentlessly pushing to expand use of the fuel, which already benefits from a tax credit of 51 cents a gallon for producers of all forms of ethanol.

And in states like Illinois, the country’s second-biggest corn producer, after Iowa, politicians are lining up state financing to subsidize the installation of pumps at service stations, while offering rebate incentives to customers who use the fuel.

“E-85 is really I-85 — it’s about energy independence,” said Daniel Yergin, chairman of Cambridge Energy Research Associates, an energy consultancy.

But that dream remains far out of reach. For one thing, E-85 barely exists outside the Corn Belt. You cannot fuel up on it in New York or New England. California has only one station.

And even in Chicago, at the entrance to the ethanol corridor, it was hard to find a flexible-fuel car for the road trip. When Janet Conlon, a travel agent from Garber Travel, contacted four major rental car agencies, none said they had such cars available.

“Nobody had a clue what I was talking about,” Ms. Conlon said. The Times ended up renting a flexible-fuel Chevrolet Impala from a company affiliated with General Motors.

At the first stop, Becker’s Hotrod BP in Dwight, Ill., 75 miles south of Chicago, E-85 was selling for $2.70 a gallon, 50 cents cheaper than the station’s regular unleaded.

Four years ago, the Illinois Corn Growers Association approached Phillip E. Becker, the station’s owner and a longtime gasoline retailer, with an offer to pay to install an E-85 pump, an investment of about $100,000. Because the alcohol in E-85 corrodes traditional gasoline storage tanks, a new underground one was necessary, along with special fuel lines and a special dispenser.

Mr. Becker, wanting to help local farmers, accepted the deal, agreeing to sell the E-85 at no profit for at least five years so he could offer it at a price lower than gasoline.

“I am selling this at cost as a good-will thing,” Mr. Becker said. The E-85, he said, also helps bring passengers into his store for sodas and collectible toy cars, and into an adjoining Burger King, in which he has a business interest. But without the help of the growers’ association, he said, he probably would not have made the investment.

Mr. Becker has enjoyed the local celebrity his E-85 pump has brought him. Officials from the state of Illinois have even shot photos there for postcards that are placed in the vehicles of state employees, urging them to stop at Becker’s.

E-85 sales at his service station, though, have proved erratic. They rose as high as 9,000 gallons a month in September last year when gasoline prices climbed over $3 a gallon, widening the spread with ethanol prices. But in July, Becker’s pumped only 3,010 gallons of E-85, after gasoline prices dropped and ethanol prices rose.

Mr. Becker said he had “four really good customers,” two of them believing so strongly in E-85 that they traded in their vehicles for flexible-fuel ones. “E-85 is all they burn, no matter what the price is,” he said.

The farmers continue to champion their project. In June, they parked a small 1940’s-era corn wagon at a highway ramp near Mr. Becker’s stations to advertise the E-85 price. General Motors included him in a recent regional promotion in which the company gave away $1,000 in free fuel — E-85 or gasoline — to purchasers of flexible-fuel vehicles.

The three-month promotion, however, did not help overall sales at nearby Tyler Chevrolet/Buick, said Byron Moore, the new-car sales manager. At best, it may have caused some buyers already set on certain truck models to choose the flexible-fuel engine to grab the free fuel.

But Mr. Moore said he doubted the buyers would actually fill up on E-85 very often, because “the word is out” that the fuel offered less mileage per gallon than gasoline. Ethanol is made up mostly of alcohol and yields less energy.

Mr. Becker said he saw E-85 sales slip when the price got to within a dime of gasoline. Mr. Beck, the E-85 customer in Springfield, said he had decided that E-85 was worth buying for his Ford truck only if the price was at least 30 cents lower than gasoline.

Volatile ethanol prices in recent months, driven by a regulatory change that has led to its increased use as a 10 percent additive in more states, have stymied the goals of E-85’s supporters. The National Ethanol Vehicle Coalition, a lobby group founded by corn growers, had estimated the number of stations would grow to 2,500 this year. Now, the coalition is willing to settle for 1,200, said Michelle Kautz, a spokeswoman for the group.

Still, the buzz over E-85 is growing — where it is available. Further south along Interstate 55, Theresa Kight, a cashier at a Qik-n-EZ in Normal, Ill., said more customers were asking about the station’s E-85 pumps. “A lot of them that are interested buy it just to support the farmers,” Ms. Kight said.

Outside the station, though, Kevin Hart, a heating and air-conditioning service contractor, was fueling up his van on gasoline. “Using more E-85 won’t solve the problem” of too much oil consumption and too little conservation, he said. “People will just think they are helping the environment, so now ‘I can burn more fuel.’ ’’

But the owners of Qik-n-EZ said they believed in E-85’s potential to diversify the country’s fuel sources — and help the Midwest’s economy. Grady Chronister, the president and founder of the company, said the stations, which get all their ethanol from VeraSun, were selling the E-85 very close to cost.

“This is not a product that warrants the financial investment at this time,” said Mr. Chronister, who added that his family owns farms that grow corn, giving them extra incentive to support E-85. “But we are glad we did it. We are in favor of alternative energy forms, especially those produced here in the United States.”

Along the ethanol corridor very few people were actually buying E-85. At a Qik-n-EZ in Springfield, there was a 45-minute wait before the first customer, Mr. Beck, arrived to refuel his 2006 Ford F-150 truck at the lone E-85 pump set well away from the four rows of gasoline pumps.

After buying his truck in April, Mr. Beck discovered only two months ago that it was dual-fuel. In the past, most drivers did not even know they had flexible-fuel vehicles because the car companies did not bother to tell them and the engines are virtually indistinguishable.

But from now on, “we’re going to do more to let people know what they have,” said Susan Cischke, vice president for environmental and energy engineering at Ford. She said Ford marked its flexible-fuel vehicles on the hood and fuel cap.

American automakers hope to double annual production of flexible-fuel vehicles, to two million, by 2010. There are now about 5 million on the road, out of 238 million total vehicles.

Detroit has much to gain from producing E-85-ready vehicles. In addition to acting as a positive diversion from their broader financial problems, the flexible-fuel vehicles help them meet federal standards for average fuel economy without having to build far more expensive hybrid cars.

But car companies bristle at the notion that they alone can make E-85 a national or even regional success. “This is a bigger problem than one industry can solve,” Frederick Henderson, the chief financial officer at General Motors, said recently.

Major oil companies, which own fewer than 10 percent of the country’s gasoline stations, say they will not stand in the way of retailers who want to put in E-85 pumps. But they will not help, either.

That has placed the burden on the states where E-85 is linked with the success of ethanol. This year, Iowa, the country’s biggest corn producer, began giving its retailers a 25-cent-a-gallon credit for selling E-85 and is providing up to half the cost of installing E-85 pumps. The governor of Illinois, Rod R. Blagojevich, just proposed spending $30 million to add 900 pumps over the next five years, a sevenfold increase.

At the retail level, however, the effort to trumpet E-85 is inconsistent at best. Mr. Beck said he found the Springfield station only after doing some research, because the E-85 Web site run by the National Ethanol Vehicle Coalition lists pumps only by city, with a limited mapping function that fails to show drivers their location in relation to each other.

Unlike the standard gasoline pumps, the E-85 pump at the Qik-n-EZ did not take credit cards, forcing Mr. Beck to stand in line for 15 minutes behind customers buying beer, cigarettes and lottery tickets.

“You would think it would be as easy as buying fuel,’’ he said, “but it is a pain in the fanny.”

And there is no room for error when trying to drive only on E-85. Do not leave Emporia, Kan., for instance, without fueling up a nearly empty tank first. Otherwise, somewhere on the Kansas Turnpike the fuel gauge needle goes below empty.

What then? Turn off the air-conditioning, coast part of the way in neutral and, finally, a service station — the only one for another 30 miles — has gasoline. But no E-85.

Well, I agree with most of your points. Here are my views on hybrids, e-85, and diesels.

E-85 and Biodiesel are wonderful alternatives to foreign oil, but they aren't going to be widespread until the mfrs stick behind them and prices come down. BioDiesel is much better since it is blended with regular diesel, only slightly increases the price, requires no modification, and reduces consumption of foreign oil. E85 isn't approved for use in all vehicles by mfrs. and the cost is much higher than regular gasoline. Gasoline engines already have milage working against them and you don't have to be a math professor to figure out that it isn't worth it when it costs more and yields less mpg. The only reason I can see someone using it is if they really want to put money back into the local economy...which is usually the reason people buy bioD. On the other hand, BioD has about 10% less BTU then D2 but since diesels are already much more efficient than gassers, 10% isn't that big a deal..especially when using a lower blend like B2 or B5. The major problem down the road is that we can't meet the demand for fuel with E85 or BioD...so the best we can hope for at this point is to reduce our Dino oil consumption with a renewable source of fuel.

Hybrids simply aren't worth it IMHO. In order to get the most benefit you would have to live in 70deg temps all the time (won't require A/C or heat) and drive in city stop-n-go 98% of the time. What they are good for is reduced emissions, and more performance. The batteries are VERY expensive.

With the new ULSD, I think we will see a lot more diesel offerings because auto makers will be able to market them to all 50 states (instead of 45). From a financial standpoint, it just doesn't make sense to most of the automakers to put diesels as an option when they can only sell them in 45 of the states. Also, GM poisoned a lot of people against diesels back in the late 70s & early 80s. It is going to take a lot of marketing to get that stinky, smelly, smoky, unreliable image out of Joe/Jane Consumer's head.

The quickest and easiest solution to the fuel crisis is the Diesel Engine and BioDiesel Fuel. Biodiesel does not degrade performance or mileage compared to straight diesel by any big amount and it can be blended based on availability. Hybrids are not that far away from being a vialble solution also. They just have to reduce the "premium" they charge the consumer for the "priviledge" of owning one. A Diesel Hybid would be the best solution IMHO. You get the best city mileage with the Electric Motor that engages for stop and go traffic and the best highway and crusing mileage with the Diesel Engine. Even offroad the Electric Motor would be nice. They put out instant torque and you "could" run silently if you had a "switch" to disengage the Diesel Engine. I even think with a roof modified as a "solar panel" you could run around town in Electric Mode most of the time.

If that doesn't do it then we have to put a mast with a sail on our Jeeps and drive on windy days...

In order to reduce the premium, they would have to reduce the cost of the extra parts. The battery alone on these things is over $3,000. Plus, they have to give customers longer warranties on the hybrid power train to cover the battery going bad at say 60k miles. Not only that, but once the battery has lost it's peak charge....it is all downhill from there as the amount of time the battery can go between full charge/discharge will become shorter and shorter which of course translates into a decrease in fuel economy.

This is my idea, and I know it may sound crazy...but with the motor and transmission all being computer controlled, why couldn't way have a switch that allows us to adjust the performance of the vehicle. This would be very similar to modules that are added after-market that have various different settings for performance. You could have an economy map and a performance map in the ECM and TCM on a vehicle, and a switch or button to manipulate this setting. The most important part being that you could stay in economy mode most of the time and then switch into power mode when you want to have fun, climb hills, tow, etc. They are already increasing fuel economy on large V8 engines using cylinder deactivation or DOD technologies, why would this not be possible? The problem with hybrid vehicles is that you more equipment which means more can go wrong. If you want an electric car, why not create a vehicle that runs primarily on electric and has a single cylinder generator running on BioDiesel to recharge the batteries. Talk about economy....now that would be some economy.

I like the diesel hydraulic hybrids. The technology is an assembly of proven technologies that have been around for years. Eaton currently has a working Humvee that is being tested by the military.

The air car is pretty cool too. It is amazing what research is/has been going on. I hope some of them will start to take off soon. I have high hopes for hydrogen powered cars, not so much in fuel cells but from a compressed tank. Hydrogen is so simple to make that it is ridiculous. There is so much promise in a lot of technologies it is hard to guess which will win out.

I generally agree with most of the points here with the obvious note that biodiesel is the way to go. For those who doubt our ability to produce enough bioD, google "algae biodiesel". Some guys from UNH (I think) have found a species of algae that make an oil that can be refined into biodiesel. They estimated that they could transition 100% of US diesel demand by planting this algae in the cooling ponds of US power plants. This is effectively free land as it isn't used for anything else.

And I have to disagree on the hydrogen point. The math simply doesn't add up.

See: http://www.caranddriver.com/article.asp ... le_id=9978

Basically, it takes WAY more energy to get the hydrogen and then compress it so it will fit in the car than you get back out of it in energy.

The only way hydrogen could ever work is if we figure out fusion such that electricity is so cheap we don't know what to do w/ it all. And then in that case cars should just run on batteries. :wink:

You are right about electricity having to be flowing out of our ears in order for hydrogen to work, but if wind and solar really take off, well its all solar if you think about it, then that will be a possibility. Then you are stuck with how are you going to store all of that energy, batteries MAY come a long way fast but especially for the auto industry hydrogen makes more sense. Batteries will probably always need an extended time to charge in order to get a long run time from them.

Now the Biodiesel by way of algae, that is slick. I read about that years ago in a book called From the Fryer to the Fuel Tank, or something close to that.

I have also been reading about the Jatropha plant that they are growing in some 3rd world countries to use for biodiesel production. I think I read that it can produce 1600 litres/hecatare or about 171 gallons/acre. Im not sure how promising that is but it is getting some people out of poverty, on land that was basically farmed out years ago.

Jeger, hydrogen is a red herring, pushed by demagogues to distract the weak-minded masses from the real problem: the need for more responsible primary energy sources.

There is a simple thermodynamic Law of Nature here that we all need to understand: on THIS planet, hydrogen cannot ever become a primary energy source because to make it you MUST put in more energy than you can possibly get out of using the hydrogen.

In short, hydrogen is a water pipe, not a well. It is at best, and then only by the solution of some daunting technical problems, a way to move energy from here to there, not an energy source. And we already have bunches of very good ways to move energy. It is energy sources on which we are short.

So, hold fast to those high hopes for hydrogen for us, will ya? They'll keep you mostly out of the way of those of us trying to come up with real solutions.

Just one minor caveat to your point-what you say is true with present technology. It is within the realm of possibilty that a new catalyst, or chem engineering breakthrough will change the equation.

Naturist,
Just what is a Primary source of energy? Biodiesel, no, it is made from oils from plant and animal sources, Crude oil, no it is made from really old, plant/animal sources. Coal, no, natural gas, no. Hydrogen, NO. Propane NO. Plant and animal sources, NO. Hydro power, solar panels, geothermal power, NO, NO, & NO. Every kind of energy that we use is simply a conversion from one source to the next, flowing through the pipes as you say. The sun is the source of energy for this planet, all that we do is convert it into a form that we can use.

Converting Using and Storing that energy in the most efficient way is what we need to figure out. You will never get more or even the same amount of energy out of something that is put into it. How energy efficient is it to make hydrogen? I dont know. How energy efficient is it to make biodiesel, including what it takes to plant and harvest your crop or to grow and process some algea?

I am not getting in anyones way to a solution, I will support most any effort for clean renewable "conversion" of the suns energy that someone wants to go for, the cleaner the better. Which way is going to be the best? I couldnt tell you, but if you dont keep an open mind we will never find out.

Naturist sure is full of himself as usual. It's a shame all of us weak minded people get in his way. Now about all those plants and animals that must have lived miles below (under the sea floor) the Gulf of Mexico to produce the new oil field recently discovered.......kinda makes ya go hum!

Yeah Im not so sure about the formation of oil myself... We may learn one day that the earth has an oil cycle, just like it has a water cycle, oxygen cycle etc. I hope that is not the case though. Imagine the pollution if we learned that it is impossible to run out of oil :!:

That's tight, the primary source of nearly all other forms of energy here is the Sun. Hydrogen may be the exception.

There are ways to convert Hydrogen that are more cost effective, Solar for one. The problem is storage since Hydrogen is hard to compress into compact containers without liquifying which brings on its own issues. At some point there will be a breakthough in technology that will make Hydrogen more practical just as there have been breakthoughs in other areas. In the meantime we need to focus more on bio fuel solutions.

There are two things that the developed nations can ill afford. They are 1) reliance on others for energy and 2) reliance on others for food. These are the two things that we just don't get in the US. We develop our most productive farm lands for cookie cutter houses, strip malls and manufacturing plants and then import food with little production oversite with respect of safety and health from third world countries. We have used food as a diplomatic weapon for decades. In the last six years we have reversed the trend of being a food exporter to becoming a food importer. The day will come when we hqave the tables turned on us with food just as we have with oil.

Google "Solar Striling" and take a look at those setups if you havnt already. Seems like I read that they can reach about 30% efficiency in converting sunlight into electricity, that is not bad at all. And they are really not that complicated.

I agree with the priortizing bio fuel advances. It is an easy fit with current technology, Im not sure how ethanol will fare but biodiesel might be hard to stop now.

Naturist is right, hydrogen at present is an energy transfer medium, like the power cables from an electric plant to your house. At present, we have to produce hydrogen, using more energy than what we get out of it. If and when we learn to produce hydrogen such that we get more energy out of it than we spend producing it, then it could be considered an energy SOURCE, or more correctly, the means used could be considered an energy source (algae, etc).

Hydro, coal, oil, solar, etc are usually considered to be energy sources because we can readily extract far more useable energy out of them than what was spent converting their energy to a useable form.

That's what a big part of the debate on ethanol and biodiesel is about, whether or not tha amount of useable energy we get out of the finished product is worth the amount of energy spent producing them.

As far as using hydrogen in your car, and especially hydrogen fuel cells in your car, I wouldn't hold my breath. Barring an unforseen breakthrough, we're talking decades if ever. Even the engineers working on developing cheaper fuel cells say they just don't see them ever being cheap enough to justify putting them in autos. And there's also the question of building an entirely new fueling infrastructure.

Any bio fuel or alternative to dino is easy to stop. All are more expensive than dino so all you need to do is magically find a new, plentiful source of dino (read the recent gulf discovery here) and drop the price of crude just as te new bio sources are getting traction. Keep the price lower (but never as low as it was) and complain about government intervention until the bio alternatives are forgotten, the technology developers are off on new projects, then start jacking the prics up again.

Europe deals with this by taxing dino to make bio more comparable in price and limiting dependence on foreign oil in the mix. Even if bio fuels can not replace 100% of dino, any reduction in imports is a step ahead. It is also a step in improving our environment rather than fattening a half dozen CEO's stock portfolios.
