from bugs to fuel

new way to make fuel. quote from the article

"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."


I hope we can have some of these bugs at home.



for some reason the link didnt work, but here is the story:

"From The Times
June 14, 2008
Scientists find bugs that eat waste and excrete petrol
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.”

this is pretty big news, surprised noone posted any reply's.

Some of the investors are pretty big guys, guy that founded Sun microsystems who is richer than hell.

The company is still private(wanted to buy stock) probably wont go public for a long time if ever.

Yeah, first thing I thought of was to buys dome stock . . . private, doh!

I'll be keeping my eye on them.

There are quite a few companies here in the valley that are focusing on renewable and alternative energies. It's becoming the dot-com of this decade, and some of the concepts are quite bizarre!

We'll have to wait and see if bug crap replaces diesel in the near future...

folks were talking about developments in biofuels from algae and biodiesel years ago. I think algae was even subsidized back in the 70's but it never went anywhere because oil dropped back down.
These crazy prices might be just what we need to finally kick the middle east oil habit.
Imagine what things would be like if we DIDNT need saudi arabia, etc?
A major shift in political power.

Many of these discoveries were started many years ago in the '70s and after, when the 1st oil crisis hit the world.
Many of these were silently put to an end from Oil companies that bought them out.

I am glad they are coming back

This isnt algae though. Algae requires sunlight + acres of shallow water, then you harvest it, and process it and gather the oil.

This bacteria will be capable of just receiving simple sugars from most anything and turning them into an oil product. Keep feeding it and it will keep producing and multiplying.

probably all in a closed system in a building.

i believe the article mentioned using sugar cane from Brazil to make 50$ a barrel oil Without Subsidization.

Thats fantastic, and there are other things im sure they can make it use, such as wood chips from the lumber market?

All kinds of things that might be considered garbage could be recycled in this way to make cheap oil, just reprocess it with these bacteria and turn it into a different form of energy.

Meh im just very interested in this.

there is a fairly long video of the man involved with this, on the internet ill post up in a few minutes when i find it.

he explains the process a little bit in this presentation.
