Bugs Eat Wast and Produce Petrol

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

“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

Electric Sports Car Rolls Out

A sports car that can go from 0 to 60 in 4 seconds — and is 100% electric. You have to plug it in for a recharge every 250 miles or so, but it's a small sacrifice for something that gets an equivalent of 135 miles per gallon (conversion of electric energy into gallons of gas gives the mpg amount).

Mike Strizki lives in the nation's first solar-hydrogen house. The technology this civil engineer has been able to string together – solar panels, a hydrogen fuel cell, storage tanks, and a piece of equipment called an electrolyzer – provides electricity to his home year-round, even on the cloudiest of winter days.

Mr. Strizki's monthly utility bill is zero – he's off the power grid – and his system creates no carbon-dioxide emissions. Neither does the fuel-cell car parked in his garage, which runs off the hydrogen his system creates.

It sounds promising, even utopian: homemade, storable energy that doesn't contribute to global warming. But does Strizki's method – converting electricity generated from renewable sources into hydrogen – make sense for widespread adoption?

According to some renewable-energy experts, the answer is "no," at least not anytime soon. The system is too expensive, they say, and the process of creating hydrogen from clean sources is itself laced with inefficiency – the numbers just don't add up.

Strizki's response: "Nothing is as wildly expensive as destroying the whole planet."

Life free from the power gridStrizki lives with his wife in a rural section of Central New Jersey. His 12-acre property is surrounded by trees and his gravel driveway leads to a winding country road. His 3,500-square-foot house has all the amenities, including a hot tub and a big-screen TV.

It was here, four years ago, that Strizki set out to do something that's never been done in this country – power his home completely through a combination of solar and hydrogen. "My motivation was, I saw what fossil fuels were doing to the environment," he says.

Strizki works for a company that installs solar panels. In previous jobs, he's helped integrate hydrogen fuel cells into cars, a boat, a fire truck, and an airplane. His latest project, the one involving his house, is an extension of that expertise.

Geothermal Power Dissed by Administration

The Bush administration wants to eliminate federal support for geothermal power just as many U.S. states are looking to cut greenhouse gas emissions and raise renewable power output.

The move has angered scientists who say there is enough hot water underground to meet all U.S. electricity needs without greenhouse gas emissions.

"The
Department of Energy has not requested funds for geothermal research in our fiscal-year 2008 budget," said Christina Kielich, a spokeswoman for the Department of Energy. "Geothermal is a mature technology. Our focus is on breakthrough energy research and development."

The administration of George W. Bush has made renewable energy a priority as it seeks to wean the United States off foreign oil, but it emphasizes use of biofuels like ethanol and biodiesel for vehicles and nuclear research for electricity.

"In spite of its enormous potential, the geothermal option for the United States has been largely ignored," a recent study led by the Massachusetts Institute of Technology said.

Last year, the DOE requested no funding for geothermal for the 2007 fiscal year, after funding averaged about $26 million over the previous six years, but Congress restored $5 million. This year, the DOE's $24.3 billion budget request includes a 38 percent federal spending increase for nuclear power, but nothing for geothermal.

Advocates say they hope Congress can restore at least $25 million in funding to keep geothermal research on track.

"It's too early to pick our resources. We need them all," said Karl Gawell, executive director of the Geothermal Energy Association.

New geothermal power projects by 2050 could provide 100,000 megawatts of electricity -- enough to power about 80 million U.S. homes, or as much as U.S. nuclear power plants make today, the MIT study said.

But U.S. geothermal development will need $300 million to $400 million over 15 years to make this type of power competitive versus other forms of power generation, the study said.
