An Alternative to Alternative Fuels and Vehicles
markmcb writes "While the world is working to solve energy and environmental issues with today's petroleum fuels, some vehicles simply don't have good alternatives, namely off-road platforms. For those not willing to give up their gas-guzzling habits, Matt Vea offers an innovative alternative. Using the OBDII interface in his Jeep, a laptop, and the infinite power of Excel, Matt conducts some performance tests and uses the results to tweak both his vehicle's engine and his personal driving habits for optimal fuel consumption both on and off road." Rigorous testing and good use of available technology; nice work.
Move to the city, man's natural habitat.
And now, a PSA from David Lynch.
Since such a large portion of SUV consumers are suburbians who go everywhere on well-paved roads and never use their vehicle's off-road capabilities, I think choosing a more economical car the next time around would be a better way to conserve fuel.
Petroleum!
Great idea. Let's burn coal to power our cars instead of oil.
Huge improvement, sir. Or at least it is if we have clean coal power.
I pretend to know more than I really do by mooching off google and wikipedia.
Duh!
Res publica non dominetur
Look.. back in the early 80's my uncle, a doctor, used to keep an SUV for cases when emergencies demanded he trundle off through snow bound michigan streets to see critical patients, but in today's age more than half the vehicles on the road come with all wheel drive and traction control, and luxury sedans now have the option of adjustable suspensions to increase ground clearance. He has one of these now and it serves him better.
Further, fewer than 1% of SUV owners actually take their cars offroad. Most people now buy these things for their own vanity and nothing else.
Meanwhile, while they guzzle fuel at 3mpg, they drive the price of this increasingly limited and taxed resource to the point where there are news reports of the working poor having to pawn off household objects merely to make it into work.
At this point this activity is approaching immorality. I know of few other activities (besides lobbying) which actively make other people poorer for no reason.

"...the infinite power of Excel..."

I beg your pardon? Since when does proprietary software have infinite power? I think you mean the infinite power of OpenOffice Calc!

Reduction is a way more important first step than switching. Once people have reduced their energy needs, then current, as well as future, alternatives are more viable.
Engineering is the art of compromise.
Why is this on slashdot exactly? This guy just tuned his car and followed some tips we've known about improving gas mileage for years. This isn't a new alternative to alternative fuels and vehicles, this is stuff car guys have been doing ever since the first ECUs were put into cars (and before that they'd have to change a mechanical system to tune the car.) Normally it's to improve performance but it can be used to improve gas mileage also.
As far as I can tell any means of electric vehicle would be an absolutely kickass offroad vehicle. The extreme torque and smootheness of electric motors are ideal for rock crawlers and other similar 4wd vehicles. It doesn't really matter where you get the electricity from. Heck, imagine one truck carries a giant fuel cell and tows the rock crawlers to the hills while powering them up too. Hybrid would be cool too, but you'd still have the gas/diesel engine to deal with.
*The most erroneous stories are those we think we know best - and therefore never scrutinize or question.*
At this point can we just admit we are all screwed?! Cheap abundant oil is vanishing and there is no plan B.
Ethanol - Not going to happen. Best case EROEI of just 34% compared to 3000% for light sweet crude???!! Ethanol is not going to happen
Hydrogen - Another non-starter. No way to store it for long periods. Negative EROEI.
Biodiesel - EROEI of 95%, still not nearly good enough to keep the interstate highway going.
Nuclear Fission - Too many enviroweenies, too specialized, too long to build a plant.
Wind - Fine for powering a small town, but no where near the power needed to run modern society.
Solar Photovoltaics - Another non starter. Not enough raw materials to make the necessary panels.
Solar Thermal - Useless above 30 degree+ lat
Nuclear Fusion - 50 years away
And as everyone knows, electricity comes from the wall! I suppose it is true that burning mass amounts of coal/oil is more effient than the small amounts in cars, but it still takes energy. In my area, we are lucky to have cheap hydro electric power, which is relativly good (I know, land use, CO2 from the decaying plants dug up from the site, etc etc). Nuclear, wind, or solar would be nice. And at least what is in the article is more efficient than the standard hummer.
I have freaks! I did something right...
Too fucking bad, you'll have to get used to it. Sooner rather than later.
I have to comment on the recent redshift in the mods lately.
I've seen numerous libertarian and left winged comments modded down as flamebait, offtopic, or overrated despite being insightful or otherwise interesting, presumably because the mods "didnt agree with it".
I posit that slashdot's metamod system is broken, since it allows partisan mods to anonymously troll comment sections at their leisure.
A note to these people: you dont like what's being said? well find someone who is refuting that point and mod it up, modding other people down because you dont like what they say smacks of fascism.

Great idea. Let's burn coal to power our cars instead of oil.
You burn coal to produce electricity? What century are you from? Next you'll start telling me that your country used slaves for labor-intensive work or some such nonsense.
For instance, when driving one has to impart some amount of KE into the car. KE is mv^2. What this means is that a car going 85mph has twice twice the KE as a car going 60mph . Now, if a car is light, like a roadster at 2200 lbs, one could go 85 and not gain any more than a Pilot going 60. And yet every day I see these huge cars going 90 mph, while I am going 70, and all these people complaining about gas consumption? It makes no sense. If they were truly concerned, they would go slower than me!
I really applaud this guy. He really tried to maximize a solution using reasonable constraints. If everyone did the same, instead of whining that they are being crunched by the price of gas, we would be in a much better place.
His recommendations are good. Accelerate slowly, especially if you have a massive car. Any physics or engineering person knows how much this helps in energy expenditure. Keep tires inflated well, and if you car came with improper tires, buy new one. You SUV is not a car, and should not drive like one. Don't drive fast, especially if you make frequent stops. The energy profile will be against you. This is why hybrids are do good for the city. Do not drive fast period. Not only does it waste gas, but if imperils all other drivers.
The day that I see most SUVs in the right two lanes, going 5-10 miles under the speed limit, is the day I believe that gas prices are too high. Right now gas prices are just inconvenient.

Rather than give a small bonus to people who buy SUVs, I'd like to see a massive penalty charged to people who don't.
Are hybrids the answer? Not to the final exam, but they are for the mid-term. The answer to the final exam will need to be electric vehicles with locally generated wind/solar electricity.
Leave oil to the 18 wheelers that keep the country moving, that would drop the price to the point that the small operators can still move equipment around the country while a better way to make a fully electric 18 wheeler hits.
My mom says I'm cool.
The recommendations have direct bearing on some of the newer fly-by-wire cars. I have a 2003 Nissan Spec-V and it is all FBW. By experimentation I have found that keeping the RPM's between 2000 and 2500, depending on the gear and speed, I can get up to 33 MPG on the highway... and yes, the ECU does learn your driving habits. Now, if we could just disconnect the black box lie-detector...
How about we just stop making car engine sizes so big? The average European engine size is somewhere around 2l, why do north Americans think they "need" engine sizes in excess of 4l?
Lower the engine size some, that'd save fuel.
Ford Taurus comes to mind. V6 mid-size sedan plus a big trunk. Does better than 22 MPG!
But it's not as cool.
Blar.
ECU fuel milleage is calculated by the duty cycle of the fuel injectors. The ECU assumes optimum flow...but flow doesn't stay optimum. The closed loop O2 sensor can 'trim' the system by a crude guess at un-burned fuel in the exhaust.
It looks like the margin of error of his experiment pretyt much makes his numbers a wash.
Blar.
But there's no point in attacking a crazy idea. Crazy people, on the other hand, are ripe targets.
Slashdot - where whining about luck is the new way to make the world you want.
The fundamental assumption is that just about all gas-engined cars run the same thermodynamic cycle and about the same compression ratio these days, so the non-ideal Otto cycle runs about 38 percent efficiency. Ross then presents an empirical model of both the manifold vacuum pumping loss and the mechanical friction losses in an engine as a function of speed and load; he also assumes that the transmission is 90 percent efficient, and there is a fixed power loss from engine accessories. Throw in the rolling resistance of a car, the aerodynamic drag, and voila, you get the steady-state highway cruise no-wind fuel economy.
Crunching the numbers on my 97 Camry 2.2 litre, using gas with 115,000 BTU/gal, 80 deg F air temp, no wind, I should get 41.7 MPG at 55 MPH, 40.1 at 60 MPH, and 37.5 MPG at 65 MPH. By comparison, I did a road test both ways on a short section of freeway at 55 MPH and averaged 41.1 MPG on a fuel mileage meter connected to the OBD-II, and I get about 36 MPG on trips where I travel 65.
You would think that the dominant loss at highway speed is the air drag, and going from 55 to 65 you are increasing in speed by 20 percent so your gas mileage should take a 40 percent hit. Well it does not, in large measure because the friction in your engine along with part-load manifold vacuum "pumping loss" in large measure tend to dominate. One way to manufacture vehicles with better highway mileage would be to use smaller engines turning over at slower speeds, and the formulas show that if I put a 0.8 litre engine in the Camry, I would get 47 MPG at 65 MPH but I would not have any reserve to climb a hill without downshifting.
The EPA has their Test Car List Data web page which gives car weight, engine displacement and final drive ratio, and drag coefficient values from which one can try out this model and make predictions of the steady-speed mileage of various cars. They give a coast down time from 55 to 45 MPG in seconds and they also give a dyno drag model of the form F = A + B V + C V^2 where A, B, C are numbers in their table and V is speed in MPH.
The funny thing about their A B C numbers is that some cars have anomolously low C numbers (the V^2 air drag) but suspiciously high B numbers (viscous drag of the transmission in neutral in a coastdown test?) and similar cars (like the Ford Taurus with two different 3 litre engines) have widely different ABC numbers and even noticably different coastdowns. I suspect the whole EPA testing procedures would not hold up to rigorous error analysis -- I wonder if anyone has done any sensitivity/numerical conditioning analysis on their procedure determining the ABC numbers used to program the dyno -- but like legislation and sausage making, you probably don't want to know what is going on.
"It is much cheaper -- and more fuel efficient -- to transport 2 tons of food in a single shipment than it is to transport 2 tons of food in a thousand 2kg shipments inside separate vehicles. Yes, the food you buy from the grocery store had to be shipped there, but economies of scale apply to the pre-grocery-store shipping."
So slashdot IS saying that distributors are necessary. What next? Publishers are too?
modding other people down because you dont like what they say smacks of fascism
Either you don't quite know what "fascism" means, or you think that some government agency is modding down comments you like. Neither of those positions is any more lucid than you would appear to think the modders' opinions are.
You combat uninformed contrary opinions (in mod format or otherwise) by making unassailable, rational, non-whiny points. If you can't rise to that standard, then perhaps moaning about the mods is the more comfortable venue. Better, though, to work on the subject at hand, than to blame the audience for how poorly some comment landed on the thousands of people here who will see it.
Don't disappoint your bird dog. Go to the range.
Robert Heinlein had a nifty idea in "Coventry" - a 1940 short story. He called it a Steel Tortoise:
"..The vehicle he had chosen was not an unreasonable substitute for burros. It was extremely rugged, easy to operate, and almost foolproof. It drew its power from six square yards of sunpower screens on its low curved roof. These drove a constant-load motor..."
Maybe someone could work on one of those...
How can you say that someone should find better recreation just because YOU don't feel that it's worth the cost? I really wish that it was not necessary to use up so much of our limited resources to do what I enjoy, but I'm not about to give up all of my hobbies just because they are not good for the oil crisis.
;)
Myself, I take part in many of these fuel consuming activities. My favorite activity is skydiving, talk about waisting fossil fuels for fun, we burn gallons of jet fuel per person everytime we go up, and we do this multiple times a day. It's my money, my free time, and I'm gonna do whatever I enjoy! I also enjoy speed boats (fuel hogs), and like the author, 4x4 offroading.
I enjoy having a great time, and I have faith that we will adapt and overcome before we run out of oil. At least I hope we do, because solar powered planes are gonna be a bitch on cloudy days.

I don't think I've seen anyone comeup with an alternvative for Construction Equipment yet.
What are we to use for bulldozers, cranes and what of the machines in the logging and mining industries etc. when we run out of petroleum? Seriously.
And to cover all my bases before there's a +5 Funny reply.... before anyone thinks of mentioning it, I know of some construction equipment that used Energon cubes http://en.wikipedia.org/wiki/Constructicons. But the brand that was making it was Evil. We wouldn't want to rely on them.
But I'm expecting gas to hit $8 to $10 a gallon shortly when Israel really gets serious about blowing up the middle east (They're just getting warmed up on Lebanon.) The minute they really get pissed off and nuke someone you may as well just park your car and fill it up with mothballs.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Chill out dude...If you can pull out of your little flame there, and re-read, I said 'perhaps finding a different recreation would work best'. I never said 'no one should use SUVs to take a little kayak to some isolated stream somewhere'. I thought if someone is concerned enough about the environment to expend all of the effort the author did, maybe searching for a way to reduce their consumption to 0 would be another consideration.
Have you ever considered a very large ACME slingshot yourself??
I rarely read replies, it's my opinion and if you thought about your opinion a little more, I'm OK with that.
That article is full of errors, misinformation and fallacious arguments. Here are just a few of many reasons why NYC is not the utopia presented in that nonsense. NYC has the highest asthma rates in the country. Cyclists and pedestrians are killed by motor vehicles at a weekly rate. One is hard pressed to find any grass that doesn't have excrement and garbage all over it. And the "middle class" has been completely eviscerated in NYC - a family of 3 with an income under $100,000 per year have to live like refugees.

I am 6 feet 4 inches tall (38+ inch in-seam), and the car is *perfect* for my height, the best I've ever had. Fold down the rear seats, and it will hold my custom-made extra-large bicycle and my (5 feet 10 inch) wife's bicycle and plenty of additional stowage. No mechanical or electrical problems (it's only 4 years old, ask me in 5 years; we drive our cars >12 years). My wife decided which cars were acceptable from a safety rating perspective, and I got the one I wanted.
The car has plenty of turbo-juice to get onto the freeway from an on-ramp safely.
This is not rocket science and it is possible to have a vehicle that carries you, your friends and furniture without blowing our environmental budget. Our other car is a small sedan that also gets OK mileage (a 1996 Integra), which in a year or two will be replaced with the most efficient vehicle we can find that meets required safety criteria. Maybe hybrid, maybe low-emission diesel.
I don't feel much like an eco-nazi, but to be perfectly straight, my wife and I much prefer walking to the local supermarket: Quality time together is in short supply these days.
Anyone wanting a good buzz should consider aerobic exercise (I like riding a bicycle). With a bit of training, the aerobic rush is awesome, the biochemical effects begin immediately and last several days. Longer term, the exercise helps with stamina and delayed onset of diseases of age. I am 49, eat anything I want any time I want and am not overweight (198 lb).
The human body is built to be worked. Reasonable nutrition and good consistent workouts are just about the best way to maintain the only body you will ever have.
I like to ride my bike,

I like to ride it where I like.
For people who really do want / need to go offroad, then there are small SUVs that are quite capable: Subaru Foresters and Suzuki Grand Vitara to name a couple. On a recent trip to Uluru (Ayers Rock) via the Oodnadatta track our heavily loaded Forester got 8.5 l/100 km (US 28 mpg), with a roofbox. Their off-road ability is quite high, and can be further increased with sump guards, heavy-duty tyres, lift kits, and so on. You don't need a tank like a Landcruiser or Jeep.

Nice detailed article. I'd love to see the results for a vehicle that was less overspecialized though. My ideal test car would be optimized for expressway commuting like a Toyota Camry or a Nissan Maxima. The Jeep is really set up and styled for off road use and as far as mileage is concerned that yeilds a compromise in gearing, frontal area and coefficient of drag. I'd bet that with a Maxima or a Camry or pretty much any street Sedan or Coupe you'd find the mileage peak between 100 and 130 kph (62 ~ 81 mph). I'd love to test this out with my own fleet. Anecdotally I would say that my mileage peak is right around 100 kph and I'm pretty close to the EPA's 14% improved mileage using cruise control over flat or hilly terrain. I think that the big difference is that I'm driving sedans that are setup for the expressway so they are geared to have the mileage peak at highway speeds.

portion of the population that has a real need for an SUV. But of course they buy a real SUV, one that can handle off road. Ever notice how most SUVs handle like a shopping cart on basically all terrain.
The phrase "more better" is acceptable English. suck it grammar Nazis
For those who don't understand why SUV's are so popular in the US, It's a national overcompensation thing, big car,compensates for small appendage!
I think that the real tragedy in energy consumption is that many large municipalities don't invest in sufficient mass-transit systems. I live in suburb of St. Louis, MO. St. Louis has *some* busses and a Metro Link train that really only serves as a way to get from a few select parking lots to a couple of stadiums and convention centers. When they tried to extend the train into the suburbs to provide a truly useful system, it was voted down because people were afraid it would bring crime from the city into the suburbs. I guess criminals don't have cars?
It was really an eye-opener to visit a place like Washington D.C. that has a truly awesome train system supplemented with a lot of buses. It consisted of several different train lines, a few of which reached *deep* into the suburbs. Seattle, WA, which has a monorail capable of going TWO places, also has a magnificent bus system. There Metro transit authority has a webpage that will plan your trip based on starting point, destination and arrival times. Wifi is extremely common in the various businesses there and the city is even peppered with free municiple Wifi hotspots. So if you have a laptop with you, you never have to worry about being able to figure out which bus to take. Seattle is also currently building a more useful train system as well.
So, lord forbid we save energy, reduce carbon emissions and give the underpriveleged a leg up on getting to their jobs, because, you know, criminals don't have cars and HOLY JESUS WHAT IF WE MEET A POOR PERSON?!
The best alternative I have ever seen to improve fuel economics on vehicles is this new Flagear fully continuous gearbox: http://flagear.fladby.com/
The gearbox is computer controlled to keep the ratio between engine speed (rpm) and the effect needed optimally at all times, thereby keeping the engine speed as low as possible which in general results in up to 50-80% less consumption of fuel.
The environmental benefits will be huge. 50-80% reduction of the fuel consumption will fulfill the Kyoto- agreement 5-7 times.
What happens when you 'when-you-have-to-use-gas' and you find out you have used it all up?
Invest in some decent public transport, think long term. It won't work for everywhere but will cut a lot of those urban/suburban traffic jams. Check out how busy the car parks are in European 'park and ride' edge of town parking locations are, that offer out of town drivers the opportunity to park and then get cheap shared transport (buses, metros, trams) into the city centre 5 miles away. They are all doing the same journey (out of town to the centre) at the same time 5 days a week.
Run some decent long distance trains on main transport corridors, European trains travel at 100mph plus, faster than cars. Think about the big economic picture (how much do we save if you factor in wider aspects) than just costing the train travel at how ever much they need to break even independently.
I calculated once that my preferred vehicle (bicycle) gets over 200 MPG easily and probably even more, considering $3/gal for gas. It basically boils down to this.
How many calories can I buy for $3? Assuming pasta is $0.50/lb, I can get about 10k calories for $3, which is enough for about 200-250 miles of riding depending upon how fast I am going. Crusing at my normal speed of about 22-23MPH, I figure 40cal/mile... at an elevated cruise of 26MPH, I figure about 60cal/mile. Climbing a 12% grade gives about 100cal/mile. So, if I'm on a flat ride, the number is up in the 250 range and on a hilly ride, it could be as low as *gasp* 150.
This is an order of magnitude greater than the mileage my SUV gets... although I haven't yet figured out how to haul a load of 2x4s from Lowes to my house on the bike yet...
It's amazing to me to see the lengths that people will go to to continue to drive their crappy box cars. You look at the math he put up and it's plain as day that the lame aerodynamics are the driving force behind his poor fuel economy. Rather than shift to another, more efficient body style Mr. Vanity persists in tweaking that which will give him a 1% miles per gallon benefit. Let's all have a parade in his honor! Here's a man attempting to ignore the big picture (oil is finite, kiddies, and we're running out), why is this laudable?
For the record, I haul refridgerators, 13' sections of carpet, etc from stores in my area to my house on a bike trailer I built. I am in better shape than most of the people that I know and have more money in my account than most of them. There are options.
I'm not sure if everyone really thought this through, but bio fuel comes from stuff we would normally eat. So what happens if the entire world switched to bio fuel that's "grown in the heartland"? Will we have to chose between eating and driving? To me it just seems like a bad idea to make you're energy source and food source compete. There's already enough hunger in the world, why turn food into fuel? Do we then stop sending out foreign aid and such because we need fuel instead? As far as electric cars go, where do you get that electricity from? Probably from the local power plant which is most likely burnign coal/oil. Currently the only ways we have to make sustainable clean energy are hydro power and nuclear power(waste isn't too clean). Hydro only works in certain areas, and nuclear is protested by enviromentalists and leaves quite a mess. If we go solar, what happens on a cloudy day? Does the whole nation shut down? With wind what happens when the wind dies down for a long period of time? These are great things to help boost energy, but will not sustain an entire nation. I have no idea what the answer is, but these ideas don't seem like it.
> I'd love to see the results for a vehicle that was less overspecialized though.
:-)
sure, but if you want to compare them to the jeep on the highway, it's only fair to have them also compete offroad.
i've got an olds aurora with a v8 (a very aerodynamic sedan), and have been doing quite a lot of the same analysis this guy, though less formally. I can get 30 mpg if i'm very gentle on acceleration, keep it under 75 mph, etc. Drafting can probably get it to 35 mpg with two car lengths between, but the guys that drive the semis don't like that much. I think you might be able to get this car to 40 mpg through modifications, running on flat terrain at sea level and keeping the speed to 60-65 mph. Maybe. I'd be surprised if you could get an accord to 80 mpg with similar approach - maybe 50-55 I'd think.
Also noticed as the author mentioned that cruise control doesn't save gas on large hills. It's way better to pull off on the acceleration until you're just doing 35 mph on the way up, and give gas until you're doing 120+ mph on the way down.
But back to my original point, this car can't tow more than 3,000 pounds (no horse trailers), has miserable clearance, and can't pull a stump worth a damn.
These arguments always kill me.
Okay, lets take a typical scenario.
You commute to work (alone), you also have a family and maybe want to tow a boat.
How about two cars.
Get an old used pocket size car for the day to day commute (this is the over-whelming majority of your miles anyway). Then get a nice newer sufficiently large vehicle for the family (and towing) for the times you need it. The nice vehicle won't get very many miles and can stay nice (keeping a higher resale value), and an old beater for commuting won't cost much to begin with and will save lots of gas. Just get an old VW Golf or Subaru 2dr or something similar (around 40mpg).
Save money, save the planet, stop arguing, yada yada yada.
----- If communism is a system where the government owns business, what do you call a system where business owns govern
Have you seen the price of gas? Some people are already starting to choose between eating and driving. Even more will have to choose when all those summer vacationers stay home, and the tourism industry lays people off.
./ -- profit is roughly what you sell something for minus what you paid to get it minus expenses. If profits are at record highs, then there's a much larger selling price than acquisition price. All because of "instability" and "uncertainty". IOW, the guys at the Big Oil companies learned a lesson from Microsoft -- they're using Fear, Uncertainty, and Doubt to make money. The only difference is that with a fungible resource that everyone uses, you don't make people fear and doubt the competition. You make them fear and doubt the supply chain, so that you can create a sense of a shortage or of an impending shortage whether or not that's actually the case.
BTW, don't let anyone tell you Bush invaded Iraq for cheap oil. No oil man wants cheap oil. They all want exactly what we have now -- scared markets that drive up the market price without necessarily raising the price of extraction and refinement. If Bush did this for Big Oil instead of his stated reasons, then the payoff is now, not after the war.
Remember, market price applies to people who buy oil on the market. The Big Oil companies don't buy oil on the marjets, they sell it there. It still costs about what it did in 2000 to extract the oil. It costs a little more to refine it because of hurricane Katrina. The big oil companies can't say it's more expensive to extract the oil because of the strife in Iraq, because oil companies weren't allowed to do business with Iraq (except to the amount of the oil-for-food program) before. The price is riding concerns over instability and uncertainty. Big Oil profits are the highest ever.
Here's a basic economics lesson for those of you who may be rusty in the discipline or may be too tired to realize it at whatever late and/or early hour you read
Your attitude is naive.
The GP -- the skydiver -- is paying for the energy he's using when he goes skydiving. He pays for the charter of the plane (probably splitting it with the other people who are going, and also paying for a lot of other stuff, like the pilot, etc.). But he paid for the energy that it's taking to get him up there so he can enjoy his fun floating down.
Likewise, the person driving the Suburban around town to get their groceries is paying for it every time they fill up its tanks at the pump. Maybe you think it's stupid and wasteful, but apparently they disagree -- and they're spending their money on the gas they're burning to prove it.
It's not as if people don't think about the cost of energy -- they do; it's just that their cost/benefit analysis comes out differently than if you did the same thing. The guy going skydiving is saying "it's worth x dollars and y liters of aviation-grade kerosene so I can go parachuting," and the woman with the Suburban is saying "it's worth z dollars and n gallons of gasoline for me to drive around in a car that's bigger than everyone else's."
They're not taking anything from you in doing this -- you could have had the same amount of gas that they did (it's not like it's rationed), if you had wanted to pay for it. When the supply starts to dry up, and the price increases, doubtless people will reconsider whether their gas-intensive recreational activities are worth the cost anymore, or whether their ginormous vehicles are really practical. But for right now, those people are voting in the most important way they can -- with their wallets -- and saying that it is worth it.
Now you could argue that the price of gas is artificially inexpensive, compared to what it should be if all the negative externalities associated with its use were taken into account. I might even agree with you there. (Although I don't think that just increasing taxes on it, whose revenue flows into general funds and is squandered, instead of actually being spent on those externalities, is productive.)
You could also argue, and here I would agree, that the companies and other entities regulating the price of petroleum products today aren't doing a very good job taking into account the future demand for their product. That is to say, they're selling too much of it too quickly right now, in order to reap short-term gains, when instead they could get a lot more for it by extracting it more slowly and selling it at a higher price to those people willing to pay. (Aviation, for instance, is impractical without fossil fuels -- very few other things have the required energy density.) However, this is a wholly separate argument from what people should be able to do with that gas, provided they're buying it at the market rate along with everyone else.
Even when gas is $15 a gallon, there will still be some people who think it's worthwhile to drive an inefficiently large car, or own gas-powered personal watercraft, or go skydiving -- and that's their decision. They have just as much a right to do that with the gas that they buy, as you do, to go wherever you want on your scooter and its tankful, which you bought. As long as both of you are paying the same price for the same product, meaning that you both get to perform the cost/benefit analysis, it's the height of arrogance to pass judgement on others' hobbies.

Certainly your skydiver is paying for the cost of his energy, as the charter company wouldn't be around very long otherwise. However, the arguement made by most environmentalists is that the price of gasoline does not include the full social costs of it's use (which is true) and they argue that they are very large (which is subject to further research and debate). From your examples and tone, I'm guessing you may have read this already, but for others, here's by far the best look at the subject. http://www.sfu.ca/~allen/CoaseJLE1960.pdf
Degaussing scares the bad magnetism out of the monitor and fills it with good karma.
Go to ebay and buy an inexpensive playpen, stroller, chair, highchair and overnight bag, and store them at your folks' house. It's amazing how much time, hassle and nerves this small investment will save you ... trust me (9 month-old son here).
I'm not saying oil is awesome or anything like that. I am also not talking about Bush or Iraq, those are totally unrelated to my question. The simple question is what happens when our nation decides that instead of producing food to eat we should produce food for fuel? I'm just asking if anyone has any hard evidence yet about whether this can be sustained. Can we make enough food to both eat and have fuel? Also, what about the other consequences of linking fuel to food. If fuel demand spikes, then food prices could also spike. Farmers will have to chose if they are going to grow food or fuel, which ultimately results in less food being produced. I don't think oil is the answer, I am just pointing out that there may be same bad consequences when we link food and fuel.
the other poster suggested replacing all of the stuff you have to carry.
Let me offer another idea. How about a compact utility trailer to haul the extras. A good one can be found for a couple hundred. An added benefit is if you are planning a weekend trip, you spouse can prepare the trailer on friday while you are still at work (as opposed to waiting for the vehicle to get home). A small trailer is also easier to load/unload than the trunk or back of an SUV. Its also much cheaper than the price differential of a bigger vehicle.
Then, you can hook-up and go.
Only yiou can decide if its the solution for you but, it should definitely get some consideration.
This isn't unlike my argument about pick-up trucks. The majority are purchased for very occational hauling. A cheap 8' trailer from harbour freight can make this up. I picked up their folding trailer. The bonus is, while folded up, it takes hardly any space in the garage and when loaded, it can be easily transferred between vehicles. Of course, for your usage, you probably want an enclosed one.

Don't disappoint your bird dog. Go to the range.
I agree another farm subsidy, oh, I mean corn based ethanol, probably isn't the way to go.
BTW, the only problem with your math is using ethanol to *replace* petroleum instead of augment it. That said, I thank you for running the numbers instead of the mouth. If more people actually examined the numbers, as you have, then these pdiscussions would have more meaningful content.
Run a google for Brazil and Ethanol, you'll see wide usage, and production from sugar beets.

An alternative to off road vehicles? How about a horse?
Sounds like a CVT (Continuously Variable Trans). CVTs are already 90% efficient and optimize RPMs. Adding another 10% efficiency will increase economy by another 10% or so, and the best CVTs get maybe 20% better mileage than a traditional automatic and are 5% better than a good manual gearbox. Another 10% gain won't cut consumption by 50-80%!
-b.
Those are all factors, but not all of which can be controlled. It pisses me off to no end that I am seeing increasing numbers of huge fricking motorhomes passing through my city here in BC, Canada (many domestic or visiting from the US). First of all, I see no reason that anyone needs to tote the equivilent to a small luxury house down the road, and secondly because the gas consumption is insane. Long weekend coming, gas goes up. I actually do see a decrease in regular users during the peaks, as many sane people wait for it to drop again. On the other hand, you will still see plenty of idiots filling up their gas-guzzling motorhomes because it seems that they can only get about 100-200km without needing another fill... usually $100-200+/fill
So why would the gas companies not jack up prices? Sure, a few people will cut back when the prices are high, but there are still plenty of idiots with SUV's, motorhomes, and the rest guzzling down more and more gas, enough to make it plenty profitable for the gas co's to keep jacking up the prices.
Nowhere near half the vehicles on the road have AWD/4WD. I would save not even half the vehicles on the road are models that offer AWD/4WD. But there are a lot of them out there. Also, your stuff about adjustable ground clearance isn't really true. The only non-SUV that had that (recently) was the Audi allroad. That vehicle is no longer available. Audi killed that vehicle in favor of the Q7, an SUV.
And people have been buying SUVs for vanity nearly forever. As you say, rarely do people take them off road. And on road, AWD doesn't make your car safer, it just makes it possible to get there sometimes when you might not have been able to otherwise. But in those cases, virtually everyone has the option to just stay home. That's a lot safer. People have been buying them because they are afraid to buy wagons and minivans (depending on the size of your loads) because they're not "manly".
There is another problem with your comments. Those sedans with AWD still get horrible mpg. You give up 2 mpg highway and 1-2 mpg city to pick up AWD. It is very difficult to find an AWD sedan/wagon that gets over 25mpg highway. My A6 gets 24mpg. The allroad variant of it mentioned above gets 21mpg. This is all dismal.
The working poor needing to pawn stuff is because you can get secondhand SUVs very cheaply, especially Explorers, which get truly awful mpg. People need to be smarter with their money. Don't just buy the cheapest vehicle, buy the one you can afford to run.
Unfortunately, this cuts both aways. When buying my A6, I look at the options, and it would have been much cheaper to buy an SUV for $30K even though the mpg would be worse, compared to the $44K I paid for my A6. If I had made the fiscally smart decision on buying, I would be using even more fuel than I am right now.
There's only one way to incent people to buy vehicles that get better mpg, despite higher initial price. Unfortunately it's very unpopular.

Wow, welcome to slashdot, where any fool can post whatever fiction they want. How about not posting tax info until you move out of your parents' basement and file a tax return or two?
The tax break _was_ (its since been repealed) for small businesses (not individuals) purchasing vehicles with a GVWR over 6000lbs. This most definitely does not include a honda CRV. Absolutely nothing to do with anything "off-road".
It was mostly designed to help farmers, since (pre-SUV popularity), 6000 lb weight ratings were pretty much just for big pickups actually used to haul stuff. Nowadays, very large SUVs bought by doctors/lawyers (=small businesses) were qualifying for the tax break, so it was repealed. Think of it as a "bug" in the law, which got fixed fairly quickly, by gov't standards.
I made a trip to Puerto Rico last year, and I was a bit amazed at the architecture: with the exception of downtown San Juan and tourist hotels, all of the habitations have no glass. Designs are built open to the air, with shutters built-in to all the windows. There are window air-conditioners, but nobody bothers with forced-air HVAC systems.
Sounds inefficient, right? Wrong. For most of the year, the people leave their houses open to the air witout using the AC, and it is quite nice. During the humid summer months, when mosquitos are about, they use the shutters to close up the house at night, and run the window air-conditioner to cool the room enough to sleep.
This is a nice compromise, because in a place like Puerto Rico, glass is an expensive building material, and is also a liability come hurricane season. Shutters make a lot more sense, both as hurricane protection, and as a cheap way to insulate and easily cool single rooms.

The cartels controlling the oil prices are in the mideast and we
can't do anything abou that.
And yes, the gasoline consumption of the USA does make up a nontrivial
fraction of global oil consumption, and now half of US personal
vehicles are "light trucks & SUVs", whereas by actual utility,
it ought to be about 10%, as it is in most other places on the planet.
In other words, banning needless trucks and SUVs in US would be as
significant in oil consumption as many of the largest oil projects on the planet
put together.
Want to cut gas consumption in half? Start by clearing up the traffic people sit in every day. There, billions saved. It's a start
That's enormously harder because it means forcing people out of where they live
and destroying the value of the homes. Why do the hard task instead of having
people buy a damn station wagon instead of a Land Rover?
Obviously, its a politically incorrect hypothesis but, seems to me the main differences between, on the one hand, Europe, Canada, Australia, and on the other hand, the United States is the demographic make up of the population. America is 2/3 non hispanic whites and, I believe about 12 percent black and something like 14 percent hispanic with the rest made up of various other ethnicities. Obviously, not the same case as in the other nations (and continent) I mentioned. As the indigenous caucasian populations of Europe are displaced more and more in the coming years, you folks are going to be in for quite a surprise. Maintaining a high level of culture and society gets harder and harder when a large and growing percentage of your population accounts for the grossly disproportionate levels of crime, parasitic siphoning of social services and a general wreckless disregard for established norms of decency and civility.
Be sure to thank your precious representatives in Brussels for me.
Of course, this doesn't help us in New York, Mass, Connecticut, California, and other states who have chosen prohibition of new diesel sales until fuel regs catch up. For newer, 2007+ models, the government WILL be telling you which diesel of the two you can use, punishable by heavy fines, of course. Good luck finding the right nozzle!
Dammit Otto, you have lupus.
... If you're talking about drag racing, there's no skill involved in that boring sport. Rev up, dump the clutch, and go straight. So boring.
According to this page, drag racing fans often witness acceleration faster than the space shuttle launching or a catapult assisted jet fighter, with deceleration of up to 5G's. The possibility of separated retinae for the driver seems to indicate this sport would be anything but boring for both fan and driver.
Now imagine holding a highly modified pro-stock harley to your ass while laying face forward as your launched like a pellet from a slingshot to finally reach 180MPH in about 7 seconds. The only thing between your now dirty shorts and the hot rubber tire is a 1/4 inch thick piece of poorly insulated fiberglass. I would think anyone capable of that feat has plenty 'o skill for this sport!
Integrity is what you are when nobody is looking.
This is a typical fallacy that many people seem to believe. The power required to drive a vehicle faster increases with the cube of velocity. There's no way to break the laws of physics.
You will generally find the mileage peak of any particular vehicle at the slowest engine speed which is capable of maintaining forward velocity in its highest transmission configuration. For most cars these days, you will find that that point generally exists somewhere in the 40-50 MPH range. As an example, say 1800 RPM in 5th gear for a typical small-ish (say, sub 3000cc) engine.
Maybe Europe is a "big city" but there's a lot of public transport right across the continent. Yes there's population density in places like Netherlands, but there's a lot of public transport intercity use in rural France, Germany, etc. On the population density argument: again, back to my post: offer urban and suburban transport and 'park and ride' - get people to drive their cars from the low density place to the edge of cities and then share transport from there. For practice rather than theory discussing if public transport works I point you to: Europe, China, India: big places, lots of rural population, lots of train and bus use. Whether it 'works' or not I think is largely socially constructed, people's personal preferences play a large part.
:-) I don't benefit either way, but I like the cleaner air. My main commute is by bike into work each day, 8 miles each way, longer than some people admittedly. I travel on pedestrian and cycle only redways so cars are irrelevant to my commute. Sometimes I drive a car (me and my girlfriend bought one between us) but as somebody who tends to walk or cycle to the shops, I'm really concerned at how much people will use their cars - maybe driving half a mile to pick up a paper and a pint of milk on a sunny day.
Re: your point about public transport about not being able to pay for itself - think outside the box and say "so what?" maybe if it's a social good then it doesn't matter if it doesn't pay for itself? Nobody suggests reducing the army because it doesn't make a financial profit, it's considered to be a necessary part of the country's infrastructure. Nobody closes schools because they don't make a net cash profit from their users. Could air travel pay for itself if air fuel was taxed? it's currently exempt from fuel taxes so skews the actual cost - what would tickets cost if air fuel was taxed at the same rate as automobile fuel? Cost out public transport with its fuel tax set at zero and see what you get. At some point somebody's decided that for social reasons air fuel is tax free. How about making public transport fuel tax free?
Re: grand plans on reducing traffic - well sometimes I get the train from a small town to London, and cycle round London. So stationary autos are actually preferable to fast moving autos for me
I wish I some mod points....this comment needs to be much higher.
I have always felt that one cause of the difference between my actions and more serious environmentalists is a matter of a convenience/inconvenience factor. An environmentalist may be willing to pedal 25 miles to work, take an hour or more, arrive all sweaty, and spend another 15 mins. taking a shower. Or spend almost two hours and take the bus(I've checked the schedule...). I am not willing to do that, and ride a 45MPG motorcycle (I live in Phoenix and do this every day because my daughter drives my truck for her much shorter commute.) I'm willing to tolerate the few weeks of 110 degree heat (in full gear, mind you), while I notice the number of bikers declines quite significantly this time of year. It appears their convenience/inconvenience is different from mine.
I rarely read replies, it's my opinion and if you thought about your opinion a little more, I'm OK with that.
That poster started the discusion using his 22MPG CR-V as an example. He wanted the room. I countered that you could get a vehicle with the same or better room for better than 22MPG.
What model are your 'sports cars' that get 40MPH? They must accelerate like a tortoise.
Way to read too much into a statement and over-react.
Blar.
I see. Yes, that is definitely a concern. Sorry for being so snarky.
Hopefully, the farmers won't be the ones who have to make the decision. Most biofuels are being made from crops that are already being grown for food. Corn oil and soybean oil are often already the target, so the fact that table grains and grains for high oil content are often different stocks of seed should hopefully be a limited issue.
Using the same source for both would have an upward pressure on the prices for both, to be sure. Hopefully in mkost cases it won't knock things completely out of whack. If there was a serious drought, a crop blight, or an attack with an indescriminate herbicide (agent orange, anyone?), the prices of food and fuel would hoth skyrocket. That's the worst scenario.
OTOH, the cost of fuel to ship food from rural farming regions to urban areas is already driving prices much higher than they could be given more even use of the land. If the cost of the raw material for both goes up hand in hand, that's exponential instead of linear. The cost of fuel is also already driving up the cost of production signifigantly, since there is fuel involved in running farm equiptment. So we'd be going from two price pressures on the crops to three on the fuel costs, plus the added demand pressure from using as the fuel.
It's truly a whole new economics, and it may mean the slow return of local farms in areas that don't currently have them. Since ethanol in particular can't yet be reliably transported by pipeline, local fuel production facilities make much more sense too. It's too bad the Feds are just now getting around to wanting to update the locks and dams on the nation's main rivers, because barges are the cheapest way to ship large amounts of grain. Bigger locks mean more barges per tugboat. Trains will hopefully be used more than trucks for the large amounts of corn, soybeans, and grain oils that have to move outside the pipeline, as that's a big cost savings, too.
