Slashdot Mirror
Around The Country Without Gasoline
IronChefMorimoto writes "Autoweek has an interesting write up on an Australian man's 16K mile trek around the United States using anything but gasoline to power his variety of alternative fuel vehicles. Featured are bio-diesel Hummers and RVs, a solar-powered canoe, and an excrement-powered scooter." Note that if your car generates electricity, you could conceivably make a few bucks selling juice to the grid at peak hours.
Really? He's got a pooper scooter?
Better yet, ride a bike around the country. Bio-powered. Some emissions, but nothing the environment can't handle. :)
I watched C-beams glitter in the dark near the Tannhauser gate.
People have been travelling great distances without gasoline since prehistoric times.
Hell, Columbus crossed the Atlantic Ocean without it.
Unknown host pong.
excrement-powered scooter
I'm sure it's gets shitty mileage.
Disconnect your television. Do your own research. Draw your own conclusions. They're probably lying. Don't be a sheep.
I found most interesting that the only vaguely technical discussion of biodiesel in the puff-piece was a bit of bashing:
What the article neglects to mention is that the dino-diesel sold in California also wreaked havoc with older diesel engines, and all left-coasters have already done the trivial job of modernizing their fuel systems.How does the Slashdot Effect happen given that no slashdotters ever RTFA?
I've driven and worked on passenger car diesels exclusively for the past ten years. They're robust and reliable, but you can't just fuel them on anything. They run terribly on gasoline!
The most critical part of the diesel is the fuel pump and injectors. They run at 3000-5000 psi with very low volume per stroke, so leakage cannot be tolerated. The fuel has to be filtered extremely well (sub micron). My worry with biodiesel is that it might plug filters due to microbial growth [always a problem in diesel], or the vegatable oil hydrolyze into organic acid plus glycerol. The organic acids will cause corrosion of the injector pump plungers and injector tips. Not good at all. The fuel will also have different rubber swell characteristics, so you may get fuel leaks. I'd try this first on a imetal-to-metal Mercedes with simple to replace rubber rather than a Peugeot or VW with a fuel-lubricated pump and that main O ring soaking in fuel.
I expect vegatable oil could be made to work with additives: a biostat, acid neutralizer plus seal swell control. But it would have to remain a separate product becauase petroleum oil and vegatable oils aren't miscible. If you wanted a blend, you'd need an emulsifier, and the results might be too viscous.
Biodiesel doesn't have anything to do with cutting down emissions. You're still burning hydrocarbons.
Yeah, Daryl Hannah is on the interview circuit telling the world that the only byproducts are harmless steam and a wonderful flowery smell. She's a fucking moron.
Not relying on fossil fuels is a noble goal, but the problems of CO and CO2 emissions (and others) are still there. Burning biodiesel even creates a whole new range of compounds that burning petrolium diesel doesnt.
I don't need no instructions to know how to rock!!!!
" Biodiesel doesn't have anything to do with cutting down emissions. You're still burning hydrocarbons."
Actually, regardless of whether or not Darryl Hannah is a moron, you are wrong.
Because the carbon in the vegetable oil used to make biodiesel is already part of the carbon cycle (opposed to having been sequestered underground for millions of years), biodiesel does not, for the most part, contribute to a NET INCREASE in carbon dioxide.
In fact, research by the US DOE suggests that biodiesel use cuts net CO2 emissions by 78%.

The reason it isn't 100% is because the methanol reacted with the veggie oil to make the methyl ester comes from petroleum in the US. You can make ethyl ester biodiesel using non-petrochemical based ethanol, but the process control is less forgiving.
I have to stop at the Taco Bell and "gas up".
Free Mac Mini Yeah, it's
Do I get an invite if I don't think murder is wrong? :D
I got into an interesting argument with a fellow anthropology major[1] about this -- She says that "'Murder is Wrong' is the only 'cultural absolute'", and I say that it's a useless definition, as the definition for 'murder' changes between cultures. You could abstract the statement out to say, 'Killing is wrong in some context in any given culture.', but the definition is still useless -- every single culture has prohibitions on something, and knowing that all cultures have some sort of prohibition against killing in certain contexts is worth Fsck-All, because the definition is so vague.
It's like saying that the corner grocery store is a walk lasting between ten minutes and two years away, maybe. Utterly useless to anyone wanting to get to the grocer.
[1] Note that I'm considering a switch to biochem, mainly because I really hate all the fscking hippies in the Anthro department who can't understand that we aren't going back to teepees and granola.
