Bugs Eat Wast and Produce Petrol


Look at what's new in Silicon Valley. Could this be part of our energy future?



LINK to article


“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 re engineer 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.

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-z 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.

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.”

Power points

— Google has set up an initiative to develop electricity from cheap renewable energy sources

— Craig Venter, who mapped the human genome, has created a company to create hydrogen and ethanol from genetically engineered bugs

— The US Energy and Agriculture Departments said in 2005 that there was land available to produce enough biomass (nonedible plant parts) to replace 30 per cent of current liquid transport fuels

UK OKs human-animal embryo research

British authorities have given the go ahead for scientists to use animal embryos in their efforts to make Human Stem Cells. For moi, it isn't a question of whether this will work or whether this will be helpful to people. It is a question of where does it lead? Man, over an over again, proves that he is not capable of acting responsibly with the technology he already possesses, let alone any new technology. As if we are not destroying our ability to endure upon the planet already, what happens when the building blocks of life are f*ck'd with?

We already have genetically modified fruits and vegetables. Many that are overtaking natural species, and many that are designed to die off and not self propagate. We read that cloned meat, from cloned animals who have higher rates of disease and mutations, is in the US food system. Mmm, serve up that steak.

Where is it all leading to?

British authorities on Thursday approved scientists' use of animal eggs to create human stem cells, a ruling that will boost the supply of stem cells for research.

The decision means that researchers will be able to refine their techniques for producing human stem cells by practicing first on animal eggs, of which there is a steady supply. Similar work involving human-animal stem cells is also under way in China and the United States.

"This is good news for research, but most importantly, it is good news for patients," said Sophie Petit-Zeman of the Association of Medical Research Charities.

Scientists have been exploring the use of stem cells to cure many degenerative diseases such as Parkinson's, since the cells have the ability to develop into any cell in the human body.

The Human Fertilization and Embryology Authority said it had granted conditional one-year licenses to two institutions to conduct research using mixed human-animal embryos. In Britain, all research involving human eggs and embryos must be approved by the authority.

Scientists from King's College and Newcastle University submitted applications last year to create human stem cells using animal eggs.

Artificial Life Forms?

A scientist is expected to announce early this next week that he has actually created the first artificial life form. By learning the language of our genetic code, now scientists are beginning to write in that code. The result, and never before seen DNA strand that will be transplanted into a bacteria cell which it will then take over.

What follows, if this proves true, is a perpetual model for countless other DNA experiments to easily follow.

Some quotes from the Guardian Unlimited story:

Mr Venter said he had carried out an ethical review before completing the experiment. "We feel that this is good science," he said. He has further heightened the controversy surrounding his potential breakthrough by applying for a patent for the synthetic bacterium.

Pat Mooney, director of a Canadian bioethics organisation, ETC group, said the move was an enormous challenge to society to debate the risks involved. "Governments, and society in general, is way behind the ball. This is a wake-up call - what does it mean to create new life forms in a test-tube?"

He said Mr Venter was creating a "chassis on which you could build almost anything. It could be a contribution to humanity such as new drugs or a huge threat to humanity such as bio-weapons".


Now, let's stop to ponder all the possibilities...

Bah, nobody has ever really thought out the consequences of using any of science we currently have, and that really hasn't harmed us has it? How bad could it be?

Mr Venter believes designer genomes have enormous positive potential if properly regulated. In the long-term, he hopes they could lead to alternative energy sources previously unthinkable. Bacteria could be created, he speculates, that could help mop up excessive carbon dioxide, thus contributing to the solution to global warming, or produce fuels such as butane or propane made entirely from sugar.

"We are not afraid to take on things that are important just because they stimulate thinking," he said. "We are dealing in big ideas. We are trying to create a new value system for life. When dealing at this scale, you can't expect everybody to be happy."


Yeah, see, we are going to get a new value system for life. So, you know, there is that trade off. I mean...what the hell does a 'new value system for life' mean?

The value of life seems to be relative to who is doing the valuing. In a world of questionable ethics and morals of those in the positions to use this new science, or more pointedly profit by it, one has to assume that those that can will. Where do we then, as a nation and as a world, put boundaries? where do we ensure that our values are not compromised in the name of money, power, or any so called quick fixes to the complicated problems that we create for ourselves. Will we use such knowledge for the greater good of all? or will we use it like a new drug to hide our symptoms, to ignore our deeper issues of how we conduct ourselves in relationship to the planet and one another. In a society more and more dependent on solutions in a pill what will the pharmaceutical corporations be selling you?

Ancient Greek Astronomical Machine



This discovery shows an incredible amount of advanced mathematics belonged to someone over 2,000 years ago. Very cool story.

Scientists have finally demystified the incredible workings of a 2,000-year-old astronomical calculator built by ancient Greeks.

A new analysis of the Antikythera Mechanism [image], a clock-like machine consisting of more than 30 precise, hand-cut bronze gears, show it to be more advanced than previously thought—so much so that nothing comparable was built for another thousand years.
