Thread: Bacteria that eat waste & shit petrol

    Bacteria that eat waste & shit petrol

    So, biology is coming into its own, with many companies and laboratories designing bacteria to make gasoline. After all, we can ferment alcohol. Why not gasoline? As explained in an earlier article (Source), alcohol has several major disadvantages. First, it is corrosive to pipes. Second, it is not sufficient. Even if all the corn grown in the United States were converted to alcohol, it could replace only 12 percent of the gasoline used. Third, it is not as energy dense as petroleum.

    Wise.

    Bacteria that eat waste & shit petrol

    bacteria that create diesel fuel.
    Silicon Valley is experimenting with bacteria that have been genetically altered to provide ‘renewable petroleum’.

    “Ten years ago I could never have imagined I’d be doing this,” says Greg Pal, 33, a former software executive, as he squints into the late afternoon Californian sun. “I mean, this is essentially agriculture, right? But the people I talk to – especially the ones coming out of business school – this is the one hot area everyone wants to get into.”

    He means bugs. To be more precise: the genetic alteration of bugs – very, very small ones – so that when they feed on agricultural waste such as woodchips or wheat straw, they do something extraordinary. They excrete crude oil.

    Unbelievably, this is not science fiction. Mr Pal holds up a small beaker of bug excretion that could, theoretically, be poured into the tank of the giant Lexus SUV next to us. Not that Mr Pal is willing to risk it just yet. He gives it a month before the first vehicle is filled up on what he calls “renewable petroleum”. After that, he grins, “it’s a brave new world”.

    Mr Pal is a senior director of LS9, one of several companies in or near Silicon Valley that have spurned traditional high-tech activities such as software and networking and embarked instead on an extraordinary race to make $140-a-barrel oil (£70) from Saudi Arabia obsolete. “All of us here – everyone in this company and in this industry, are aware of the urgency,” Mr Pal says.

    What is most remarkable about what they are doing is that instead of trying to reengineer the global economy – as is required, for example, for the use of hydrogen fuel – they are trying to make a product that is interchangeable with oil. The company claims that this “Oil 2.0” will not only be renewable but also carbon negative – meaning that the carbon it emits will be less than that sucked from the atmosphere by the raw materials from which it is made.

    LS9 has already convinced one oil industry veteran of its plan: Bob Walsh, 50, who now serves as the firm’s president after a 26-year career at Shell, most recently running European supply operations in London. “How many times in your life do you get the opportunity to grow a multi-billion-dollar company?” he asks. It is a bold statement from a man who works in a glorified cubicle in a San Francisco industrial estate for a company that describes itself as being “prerevenue”.

    Inside LS9’s cluttered laboratory – funded by $20 million of start-up capital from investors including Vinod Khosla, the Indian-American entrepreneur who co-founded Sun Micro-systems – Mr Pal explains that LS9’s bugs are single-cell organisms, each a fraction of a billionth the size of an ant. They start out as industrial yeast or nonpathogenic strains of E. coli, but LS9 modifies them by custom-de-signing their DNA. “Five to seven years ago, that process would have taken months and cost hundreds of thousands of dollars,” he says. “Now it can take weeks and cost maybe $20,000.”

    Because crude oil (which can be refined into other products, such as petroleum or jet fuel) is only a few molecular stages removed from the fatty acids normally excreted by yeast or E. coli during fermentation, it does not take much fiddling to get the desired result.

    For fermentation to take place you need raw material, or feedstock, as it is known in the biofuels industry. Anything will do as long as it can be broken down into sugars, with the byproduct ideally burnt to produce electricity to run the plant.

    The company is not interested in using corn as feedstock, given the much-publicised problems created by using food crops for fuel, such as the tortilla inflation that recently caused food riots in Mexico City. Instead, different types of agricultural waste will be used according to whatever makes sense for the local climate and economy: wheat straw in California, for example, or woodchips in the South.

    Using genetically modified bugs for fermentation is essentially the same as using natural bacteria to produce ethanol, although the energy-intensive final process of distillation is virtually eliminated because the bugs excrete a substance that is almost pump-ready.

    The closest that LS9 has come to mass production is a 1,000-litre fermenting machine, which looks like a large stainless-steel jar, next to a wardrobe-sized computer connected by a tangle of cables and tubes. It has not yet been plugged in. The machine produces the equivalent of one barrel a week and takes up 40 sq ft of floor space.

    However, to substitute America’s weekly oil consumption of 143 million barrels, you would need a facility that covered about 205 square miles, an area roughly the size of Chicago.

    That is the main problem: although LS9 can produce its bug fuel in laboratory beakers, it has no idea whether it will be able produce the same results on a nationwide or even global scale.

    “Our plan is to have a demonstration-scale plant operational by 2010 and, in parallel, we’ll be working on the design and construction of a commercial-scale facility to open in 2011,” says Mr Pal, adding that if LS9 used Brazilian sugar cane as its feedstock, its fuel would probably cost about $50 a barrel.

    Are Americans ready to be putting genetically modified bug excretion in their cars? “It’s not the same as with food,” Mr Pal says. “We’re putting these bacteria in a very isolated container: their entire universe is in that tank. When we’re done with them, they’re destroyed.”

    Besides, he says, there is greater good being served. “I have two children, and climate change is something that they are going to face. The energy crisis is something that they are going to face. We have a collective responsibility to do this.”

    sounds like a pretty cool idea. 2010 only 2 years away. have to see if we hear more on this in the future.
    oh well

    why not just cut out the middleman and make a photosynthesizing bug that makes oil?

    Wesley,

    Algae oil promises truly green fuel

    THIS is one biofuel that lives up to its green billing in more ways than one. It's an emerald-green crude oil, produced by photosynthesis in algae, which could fuel cars, trucks and aircraft - without consuming crops that can be used as food.

    "This product can go right into today's oil pipeline," claims Jason Pyle of Sapphire Energy in San Diego, California, which developed the fuel. He says the "green crude" is similar in quality to naturally occurring crude oil. It is produced as a by-product of photosynthesis by a genetically engineered strain of algae, housed in tanks of treated waste-water and exposed to sunlight. The tanks can be placed on non-arable land.
    It's on its way.
    ...it's worse than we thought. it turns out the people at the white house are not secret muslims, they're nerds.

    cool idea's , like the first post stated about the room needed to do these things. maybe build a bunch of plants in some remote areas? getting oil from bugs , OPEC would shit.
    oh well

    Why not just use Salt Water that already burns at 1500 degrees???....Cause the goverment don't want it!!! All the politicans would loose to much money in oil stocks is why.

    Art,

    This could be one valid reason:

    There is another design flaw in Aquygen, one that it shares with the Kanzius RFG. Both struggle with the energy input to energy output ratio -- or efficiency. This huge stumbling block causes many to view inventions like Aquygen and the RFG as useless science. While the RFG produces a hydrogen flame that burns stably, the amount of energy it puts out is less than the amount of energy needed to power the RFG. In this sense, any energy that comes out of the salt-water flame cannot be considered a source of power. It's just a manifestation of the energy being put into it, only in a lesser amount. This makes it unlikely that the RFG could produce a real, viable source of fuel. (Source)

    Get the bugs to eat sewage. Gas production from sewage has always been in the background, but possibly if the sludge is also used it would become more economically acceptable

    what are the emissions created when burning this fuel?
