Researchers Develop Biofuel Alternative To Ethanol

coondoggie writes "Researchers say they have developed a method of using bacteria to convert decaying grass directly into isobutanol, which can be burned in regular car engines with a heat value higher than ethanol but similar to gasoline. The research could mean great savings in processing costs and time, plus isobutanol is a higher grade of alcohol than ethanol, according to the Department of Energy's BioEnergy Science Center (BESC) and its Oak Ridge National Laboratory"

      That's a bunch of fucking bullshit. With the TDI's, the only problem you'll encounter running biodiesel is maybe a dead injection pump due to seal cracking, which is caused by the lack of sulfates in the fuel... Since low-sulfur diesel was introduced about five years ago, all new vehicles have pump seals that work perfectly well with biodiesel -- my injection pump from 2002 went pretty quickly, and I had it rebuilt with modern seals that work properly with biodiesel and I've had no problems in over five years. Biodiesel will not hurt your TDI, it's a load of crap.

    4. Re:Finally! by kevinNCSU · · Score: 3, Informative

      I thought the new low-sulfur fuel came due to the new particulate emissions level mandates which are part of the problem. They added a particulate filter to the exhaust that has to periodically burn up the matter collected there. Most new diesel engines (post 2007) do this by injecting fuel into the cylinder right after the cylinder fires and exhaust valve opens so that it vaporizes and travels to the exhaust where it can heat up the particulate filter and burn off the collected matter. Since bio-diesel is denser and doesn't vaporize as easily it ends up getting stuck to the piston walls and getting into the engine oil where it dilutes it and then damages the engine.

      Not all new diesels have this problem, some companies decided to put an injector in the exhaust itself in order to deal with this, but most went the other route because it's cheaper so you shouldn't just assume post-2007 cars will run on even small mixtures of biodiesel anymore.

    Whereas right now, corn productions is managed efficiently, and the starving people all get food... right.

    Starvation is mostly a logistics and political problem. Low-grade corn is cheap near where it's produced, but that's generally not where people are starving. Moving the food to the people costs money, which raises the final cost beyond what the people can afford. A government could subsidize that cost, but that kind of action is often systematically abused and easily spun by political opponents as "propping up those greedy transport companies".

    Basic economic analysis tells us that with starving people needing food, but only being able to pay a lower amount for it, a smart distribution company will simply ignore those people in favor of markets that will turn a profit. The simplest solution is to make starving areas profitable, either with a subsidy or by lowering the cost of transport.

    The biofuel thing has always mystified me. If there are two things in the world that are more scarce and fundamental to life than oil, they've got to be arable land and irrigation water. The corn ethanol thing caused all sorts of havoc in farming and food pricing, particularly with international farmers destroying staple food crops to grow fuel plants and selling corn to oil producers instead of families. This is not the way of the future.

    If this grass can grow in otherwise unusable land, and it can grow without diverting otherwise useful drinking or irrigation water, then fine. I'm very skeptical that even if that is technically possible that it will play out as such once the prices come in and farmers have to choose between taking money from poor hungry people or rich gas guzzlers.

      The benefit of cellulosic biofuels like the ones mentioned in this study is that the entire plant can be converted to fuel (rather than just the fruit), resulting in higher yields; less land is needed to produce the same amount of energy.

      Additionally, most grasses that would be used as feedstocks, such as switchgrass, are perennial plants. According to Wikipedia:

      "The main agronomic advantages of switchgrass as a bioenergy crop are its stand longevity, drought and flooding tolerance, relatively low herbicide and fertilizer input requirements, ease of management, hardiness in poor soil and climate conditions, and widespread adaptability in temperate climates." In other words, switchgrass will be a viable crop in many areas that aren't suitable for food anyway."

    Corn does make livestock sick. If you feed a cow nothing but corn, they get overgrowths of bacteria in their rumen, produce excessive gas, and can suffer from stomach and intestinal ruptures. This is a large part of the reason why 80% of antibiotics used in the USA are fed to farm animals as prophylaxis, in an attempt to prevent stomach ruptures and feedlot deaths. You're correct, though, that the sick livestock cost ranchers. They just don't see any (fast, easy) way out of the feedlot model. The feedlot cows are ALL sick, but just healthy enough to walk from truck to slaughterhouse. That's close to all the USDA requires.
