Brew Your Own Auto Fuel For 41 Cents A Gallon
Iphtashu Fitz writes "Damon Toal-Rossi of Iowa City, Iowa had enough of the high price of gasoline, so it didn't take too much for his friend to talk him into switching to biodiesel, an alternative fuel based on soy or vegetable oil. But after a few months of driving 10 miles to a biodiesel fuel station he decided it was time to start brewing his own. It didn't take him long to find a recipe for biodiesel, and with used cooking oil that he gets for free from a nearby restaurant, he figures he's now getting 44 miles per gallon out of his diesel powered VW Golf and only paying 41 cents a gallon. According to the National Biodiesel Board the number of biodiesel stations in the US rose by 50% last year (to a whopping 200). The president of the American Soybean Association claims biodiesel has almost the same amount of energy as petroleum-based diesel, but cleans an engine's fuel injectors and cuts down on the number of required oil changes. Perhaps these are some of the reasons why diesel powered cars are making a comeback in the US."
a) Have a diesel car.
b) Have somebody who will give you free used oil.
Not all of us live nearby KFC :)
Sounds like a fun project though. The warnings about the various poisons certainly got my attention.

Nifty, but if we all went out and did this, the price would skyrocket. Hell, if only all the people who read this story on Slashdot went out and did this, the price would skyrocket.
All this story says is, "If you get free stuff, you can make other cheap stuff out of it." Regrettably, we're not solving any energy problems by starting with "If you get free stuff..."
(It's great the guy did this and I respect the hack that this embodies. But people shouldn't try to draw too many conclusions from this. All the cooking oil I've used so far this year (and I don't order many fried foods from restaurants so that's the majority of "my" share of oil) wouldn't hardly get me out of the city.)
is that biodiesel gels at about 32 degress F. So, if you are parking your car outside in below-freezing temperatures, you have to mix it with petroleum diesel and/or add anti-gelling additives.
Biodisel is a bad solution to the oil problems in america. Why? Because if 50% of cars on the road today had biodeisel, then the price would skyrocket. Why? Although McD's produces a ton of greaseburgers, there simply won't be enough used oil to produce enough fuel for everyone. Wish I had the link to the stats... I'll google around and give the link.
Good quote, too many chars. Seriously, the slashdot 120 char limit sucks!
People are not starving because there is not enough food in the world, but because in too many places the distribution system is not very efficient, or is actively perverted by armies, dictators, and other autocrats. If we can find a way to use inexpensive, renewable plant matter to generate energy, it will ultimately improve the lives of people all over the world, especially in those places too poor to buy oil right noww.
No, not really. It has more to do with skyrocketing gasoline costs and the fact that TDI technology is miles above the old diesels. It's quieter, more efficient, more powerful, the blocks are lighter thanks to superior materials, and TDI isn't nearly as sensitive to the cold- it doesn't even need the glowplugs above 40 or so degrees. The glowplug system is tied into the central locking, so when you approach the car and unlock the doors, it figures out if it's cold enough to need the glowplugs and starts warming them; as a result, the car's ready to go before you are, most of the time. Diesel is also much more prevalent now that there are a lot more diesels in pickups, vans, etc used by small businesses and non-fleet operators.
That addresses many of the concerns the public had about diesel- hard to find fuel, noisy, heavy, and a bitch in the cold.
A lot of people get hybrids wrong too, thinking it's all the hippies buying them. Dealers say that was true initially, now it's just regular commuters who want the most efficient car. Biodiesel is a boutique fuel aside from use in fleets in 2% mixes to replace sulfur in low-sulfur fuels.
Please help metamoderate.
The biggest savings these people are experiencing is from avoiding road taxes, which are a major part of the price of commercial gasoline or diesel. Right now the "underground" biodiesel movement exists in a gray area. There are too few people for the authorities to bother cracking down on, but if enough people start doing it they will. Right now, untaxed diesel for off-road use in boats and industrial/farm equipment is dyed red. If you're caught with "red" diesel in your car or truck, you'll have to pay huge fines. The dye is stubborn, too -- once it's in there, it stays for many, many tanksful.
Sooner or later there's going to be a crackdown. Making your own biodiesel may soon be illegal, for all practical purposes -- either explicitly, or through red tape that's too hard to deal with. You're either going to have to add red dye, prove that you're paying road taxes, or something.
Personally, I think the best way for the government to spur development of alternative fuel infrastructure is to offer a road tax holiday for alternative fuel users -- say 5 years or so. Let this apply to all biodiesel, CNG, hydrogen, ethanol, and electric vehicles.
.... with millions of people starving to death in the world, that we use food (soybeans, etc) to make fuel. It's really sad actually.
Nobel prize winning economist Amartya Sen argues that there has never been a famine in a working democracy. This leads to the conclusion that famines are ultimately political in nature. There's always a warlord blocking food convoys, or a landlord exacting rent right off the dinner table. Or there may be plenty of food, but the sociopolitical environment does not provide the means for a person to acquire the food.
I remember seeing footing of the great depression, in which dairy farmers dumped huge vats of milk on the ground. The problem was that they weren't getting paid enough for their milk to live on, so in protest they just dumped the milk. Perhaps they were trying to raise the price by limiting supply. In either case, if people went without milk, it wasn't because there wasn't enough milk, it was because of political and economic factors that prevented the distribution of milk to those who needed it.

There are hundreds of such companies in the U.S. alone. The government didn't bid these contracts - they awarded them without competition. Normally, government bids are extremely competitive because of large numbers of companies. Raytheon is a false analogy - missiles are not the same as civil engineering and logistics. Far more companies are available to provide the latter.
Au contraire. In many, many fields private sector margins have been cut to the bone since 1990 as competition resulted in efficiency, process redesign, downsizing, and mergers.
What government contracts offer is steady guarantees, with reasonable margins, which is why they are so desperately competed for by many companies.
However, the deals Halliburton and Bechtel have in Iraq are nearly unprecedented. They are cost-plus deals. Meaning, Halliburton tells the army how much they spent
The private sector figured out a hundred years the obvious reasons why this doesn't work: your contractor now has incentive to screw you. They get rewarded for sloppy performance and procrastination, or even outright conscious delay. And human nature is what it is.
This is why private sector contracts - and better goverment contracts - bid for a set price and deadline. Now it becomes the contractor's job to figure out how to make a profit by getting the work done under the cost cap.
The cost-plus no-bid deals handed out for Iraq are unheard of in the business world, because it's a stupid, stupid way to do business, from a purely economic perspective. But, the nature of politics today seems to make it impossible to even discuss these things without getting called a "commie librul". You know the world's screwed up when smart business sense = communist liberalism.
Another suggestion of a "company that would take the work"... try the Army. Until a few years ago, they provided almost all of their own logistics. It's not at all clear that it's cheaper to do it with private companies.
It also means the military now depends on civilian companies that can and will cut and run if the security situation gets too bad
Imagine how fast Halliburton would be gone if some terrorist DID set off a stolen nuke in Iraq, killing 1000 of their employees. But nuke or no nuke, someone's got to feed our troops. This is why Army logistics should stay in the Army.
I stole this sig from someone cleverer than me.
Gasoline is only $2/gallon if your planet is worth nothing.
I was in a college group that studied the biodiesel option, and we came to another conclusion, methane would be better. We can get it from our own societal waste products, it is much easier to store than hydrogen, and most vehicles can be converted to methane at a far lower price than any other conversion (hybrid/fuel cell/electric). There is an infrastructure in place that can be converted to dispense the product, and vehicles generally get a 3-8mpg improvement running on methane.
I have no idea why this idea has never been persued by a few corporations. All the technology is already in place, the program could be started today, and creating methane reactors for our bio-waste would actually be a simple prospect.

Hey there's this awesome invention, maybe you've heard of it, it's called the Sun. At our distance from it we receive about 1kW/m^2 of energy at ground level. That is a lot of energy to collect. Photosynthetic organisms make excellent use of this energy and can do all sorts of cool things with it.
Oh yeah we can also convert this energy into other forms and store it for our own use chemically. Crop tenders, processing equipment, water pumps, and many other aspects of biodiesel manufacture can be performed by solar powered machinery.
Besides you seem to not understand the biofuel carbon cycle is closed. Any carbon released from burning biodiesel is carbon absorbed from the atmosphere during photosynthesis. If you've got an end-to-end solar-biodiesel system you're not releasing any extra carbon into the environment. Pumping fossil fuels out of the ground and burning them is releasing carbon into the environment that has been effectively removed from it for millions of years.
