The X-Games, Microbe Edition

Monday, November 24th, 2008

Rugged microbes equipped with a unique set of survival skills find high-temperature and acidic conditions a welcome home. And scientists have a peculiar fondness for these “extremeophiles,” freaks of nature that live outside the boundaries of normal existence. These are bugs that can grow in the harshest of conditions, from sulphuric acid to high-salt environments.

Part of the reason scientists are interested is extremeophiles potential to be put to work to produce next-generation cellulosic-based biofuels.

How? These microbes can perform feats that bioengineers till now only dreamed of. They offer, perhaps, the best hope to tear down rigid plant material without using specialized chemicals or high amounts of energy and, perhaps, one day to create new fuels to power autos and trucks. Scientists and engineers at Sandia National Labs are taking the lead in the effort.

“We are looking at extremeophiles that can thrive in high temperature and acidic conditions,” said Rajat Sapra, staff scientist and engineer with Sandia National Labs. “Bugs that can grow in sulphuric acid are of great importance because nature has already done all of the genetic customization and adaption. It saves scientists trying to create superbugs with these modified capabilities.”

Over the course of the next few years, Sandia scientists are planning on working with the three different parts of the cellulosic biofuel process, which include deconstruction technologies for breaking down cellulosic materials and engineering extremeophiles for pretreatment processes.

“What we look at in terms of processes is trying to streamline these extremeophiles,” says Sapra. “If you look at stonewashed jeans, that process is achieved through the use of a bacterial extremeophile.”

The world of biofuels and cellulosic ethanol comes down to a pretty simple equation. Cellulosic sugars are based on six carbon sugars, which is common among plants. The longer the length of the carbon chains, the more energy density is stored inside the plant material. The researchers explain energy density with a simple equation of one gallon of ethanol having the same energy density as 0.6 gallons of gasoline.

Trouble is all of that energy density is locked up pretty snugly in the cellulose and lignin materials of plant, which means you have to pay an energy or chemical cost to break it down to get at the rich density of energy. It isn’t the challenge of converting sugars to ethanol, it is how to break down the plant material into a mulch that can then provide sugars.

Sometimes missing from the big discussions about biofuel processing is the energy cost of getting the foodstuffs to the place where the fuel is going to be refined. It doesn’t make a lot of sense, for example, to transport large volumes of poplar trees from one region to another by truck.

That’s why scientists like Sapra are clear about the real Achilles’ heel for making biofuels economic and scalable. It comes down to looking at the entire process as an integrated one. And the key focus is taking into account the enormous scale of the process.

At the end of the day, the real answer for sustainable, economically viable biofuels resides in grasses and woody plants, instead of food crops. Agricultural waste is a starting point. Growing and extracting for corn stover and rice straw is all about converting waste plant material that would otherwise be burned into a high-energy-density material from which ethanol can be processed and refined.

There are three basic steps in biofuel production. First is taking the biomass and breaking it down. Second is deconstructing the material into polymers. Third is converting the sugars into fuels.

Researchers and engineers are focused on the goal of taking the entire conversion of biomass material into sugars and ethanol and doing it in one large vat or container. This is called consolidated bioprocessing and has obvious advantages over other approaches in both economics and efficiency.

Even though second-generation biofuels are still years off, the ability to harness the mysterious ways by which nature has solved extremeophiles’ problems of survival is surely going to be a boon to efficient fuel production. — Lee Bruno

Sundown for California

Monday, November 17th, 2008

Twenty-five years ago, along with another young journalist, I coauthored a book called California, Inc. about our adopted home state. The book described “California’s rise to economic, political, and cultural ascendancy.”

As relative newcomers at the time, we saw California as a place of limitless possibility. And over most of the next two decades, my coauthor, Paul Grabowicz, and I could feel comfortable that we were indeed predicting the future.

But much has changed in recent years. And today our Golden State appears headed, if not for imminent disaster, then toward an unanticipated, maddening, and largely unnecessary mediocrity.

Since 2000, California’s job growth rate - which in the late 1970s surged at many times the national average - has lagged behind the national average by almost 20 percent. Rapid population growth, once synonymous with the state, has slowed dramatically. Most troubling of all, domestic out-migration, about even in 2001, swelled to over 260,000 in 2007 and now surpasses international immigration. Texas has replaced California as the leading growth center for Hispanics.

Out-migration is a key factor, along with a weak economy, for the collapse of the housing market. Simply put, the population growth expected for many areas has not materialized, nor the new jobs that might attract newcomers. In the past year, four of the top six housing markets in terms of price decline have been in California, including Sacramento, San Diego, Riverside, and Los Angeles. The Central Valley towns of Stockton, Merced, and Modesto have all been awarded the dubious honors of the highest foreclosure rates in the nation during the past year.

Even with prices down, many of the most desirable places in California are also among the most unaffordable in the nation. Less than 15 percent of households earning the local median income can afford a home in L.A. or San Francisco. In Santa Barbara, San Diego, Oxnard, Santa Cruz, or San Jose, it’s less than a third. That’s about half the number who can buy in the big Texas or North Carolina markets. Moreover, state officials warned in October that they might have to seek as much as $7 billion in loans from the U.S. Treasury. This is a disappointing turn for a state that once saw itself as the harbinger of the future.

Not surprisingly, few Californians see a turnaround soon. In the most recent Field Poll in July, a record high 63 percent of Californians said they are financially worse off than they were a year ago, while a record low 14 percent described themselves as better off. Poll director Mark DiCamillo called it “the broadest sentiment of pessimism we’ve ever seen.”

Of course, California can still attract many newcomers, particularly young and ambitious people who dream of a career in Hollywood or Silicon Valley. The problem is that when you grow up and have failed to secure your own dotcom or television series, life in Texas, Arizona, North Carolina, or even Kansas starts looking better. According to real estate analysts, the only thing preventing the current outflow from being worse is that homeowners cannot sell their residences in order to move.

All of this suggests a historic slide of California’s role as a bastion of upward mobility. In 1946, Californians enjoyed the nation’s highest living standards and the third highest per-capita income, noted journalist John Gunther. As recently as the 1980s, Californians generally got richer faster than other Americans did. Now, median household income growth trails the national average while the already large divide between the social classes - often bemoaned by the state’s political left - grows faster than in the rest of the country.

Can California recover the vitality that defines her heritage?

Today, notes a recent Public Policy Institute of California study, California has the 15th highest poverty rate in the nation. Only New York and the District of Columbia fare worse if the cost of living is factored in. Indeed, after accounting for cost of living, L.A., Monterey, and San Francisco counties - all places known for concentrations of wealth - have poverty populations of 20 percent. “San Francisco,” says historian Kevin Starr, a native of the city, “is a cross between Carmel and Calcutta.”

The Political Roots of the California Ascendancy

You can blame many factors for California’s fall from grace: too much immigration from poor countries, the impact of global competition on technology and aerospace industries, the end of the Cold War, failing schools, and the 12 years of political control by the Texas-centric Bushes. Yet other states have weathered similar storms and still gained ground on the Golden State.

The real problem lies in the decline of the state’s political culture. “Our society may be evolving spectacularly but our politics are devolving,” suggests Starr, the state’s most eminent historian. “California is in no way a role model for anyone from outside the state.”

For much of the 20th century, California - already blessed by climate, topography, and fertility - was also relatively well governed. California’s schools, universities, and infrastructure were considered among the finest anywhere. From the 1920s on, its prevailing ideology was a kind of business-like progressivism. Californians in both parties embraced the idea that government could be a positive force in the economic and social life of California. However, they also embraced the latest notions of scientific management. One report from the administration of California’s Republican Governor Hiram Johnson, produced in the early part of the 20th century, stated that the goal was “to systematize the business of the State of California.”

California’s state government laid the foundation for its remarkable ascendancy. Progressivism’s pragmatic orientation, the melding of science and technology into government, the large-scale investment in infrastructure, and a strong nonpartisan tradition produced spectacular results. In his famous book Inside USA in 1946, Gunther gushingly described California as “the most spectacular and most diversified American state … so ripe, golden.”

Another Republican California governor, Earl Warren, who served between 1943 and 1953, epitomized progressive virtues - pragmatic in policy, nonpartisan in approach, and activist in his manner. Later on, as the GOP became more conservative, the progressive mantle shifted to the Democrats. Under Governor Edmund G. “Pat” Brown, elected in 1958, the state continued with an aggressive program of public works, a rapid expansion of higher education, and the massive California Water Project.

Like his Republican progressive predecessors, Brown advocated civil rights for minorities but also promoted business interests, notably in real estate development, Hollywood, aerospace, and agribusiness. Equally important, the Democrat embraced the traditional good government principles of the progressives. Shortly after taking office, Brown initiated a thorough reorganization of state government, attempting to make it more businesslike. California, Brown himself noted, needed “to apply the latest concepts of management, organization, and cost control just as modern corporations have done.”

The End of the Progressive Era

By the mid-1960s, Brown’s traditional progressivism was being undermined by rising interest-group liberalism. State employees, left-liberal lobby groups, and minorities were demanding more and more from the governor. Fed up with ever-growing taxes and social spending, business interests became increasingly alienated. Once seen as a boon to the private sector, state government was becoming perceived by corporate interests as overly meddlesome and hostile.

Perhaps even more damaging was the cultural rift that developed. Many white middle- and working-class voters felt threatened by the rise of new militant minority and student groups. Riots at Berkeley and Watts deepened resentments against the university and African Americans, two linchpins of Brown’s support.

In the 1966 gubernatorial election, Ronald Reagan smashed Brown and the remnants of the old progressive coalition. The former actor captured both business support and grassroots votes in previously Democratic-leaning areas in suburban L.A. and the Central Valley. Numerous interviews conducted with his closest confidants at the time make clear that they did not intend to impose a conservative social agenda, but hoped to slow the regulatory regime and restore order on the state’s campuses and ghetto streets.

One scholar has claimed that Reagan “destroyed” progressivism, but some of the blame should also be laid at the feet of the Democrats. To be sure, Reagan slowed the growth of government, but infrastructure building continued and the state university grew, as did many social problems. Much the same could be said of later Republican governors George Deukmejian and Pete Wilson, whose policies were only moderately conservative.

Enter Governor Moonbeam

The real problems for the progressive model, ironically, began to surface with the rise of Pat Brown’s son, Governor Edmund G. “Jerry” Brown Jr. He veered away from the traditional focus on nonpartisan governance and infrastructure spending - what long-time advisor Tom Quinn called “this build, build, build thing” - and instead focused on an environmentally friendly, “small is beautiful” approach.

However, the real problems did not ultimately reside with the brash, creative, and sometimes unpredictable young governor himself. Entrenched Democratic interest groups, particularly public employees, resisted property tax relief for California’s middle-class homeowners. Ultimately, this failure brought about the passage of Proposition 13, a strict limit on property taxes that would sharply curtail infrastructure spending and reduce the ability of local governments to address serious problems.

During Brown’s watch, and even despite his occasional opposition, the Democratic Party came increasingly under the sway of public employees, trial lawyers, and narrow interest activist groups. Their ability to raise money and impose their political will often outweighed that of even the most powerful business interests.

The full bill for this transformation would eventually be paid not by Brown, but by his former chief of staff, Gray Davis. Becoming governor in 1998, Davis became the prisoner of the special interest groups with whom his predecessors, Deukmejian and Wilson, had struggled.

By then, California’s shift to the Democrats had become inexorable and, with the fading of a GOP counterweight, influence within the party flowed to its more radical factions further to the political left. As a result, the state moved decisively away from the economic growth focus of Pat Brown. It seemed determined to wage war against its own economy. As pet social programs, entitlements, and state employee pensions soared, infrastructure spending - the hallmark of the Pat Brown regime and once 20 percent of the state budget - shrank to less than 3 percent.

The educational system, closely aligned with the Democrats in the legislature, accelerated its secular decline. Once full of highly skilled workers, California has become increasingly less so. For example, California ranks second in the percentage of its 65-year-olds holding an associate degree or higher and fifth in those with a bachelor’s degree. But when you look at the 25-to-34 age group, those rankings fade to 30th and 24th.

Instead of reversing these trends, the state legislature decided to spend its money on public employees and impose ever more regulatory burdens on business. Davis, a clever and experienced public servant, understood this but could not fight the zealots in his own party. When the state’s revenues shrank after the high-tech bust in 2000, he appeared to be their complete captive. Perhaps the most telling example of the misplaced priorities of the state’s majority party took place amid the state budget crisis when legislators, facing an imminent fiscal disaster, took time to debate legislation about providing more protections for transgender Californians.

Enter the Girlie Man

Davis’s apparent inability to gain control of the looming budget crisis opened the door to his 2003 recall and the election of a Republican, Arnold Schwarzenegger. The former bodybuilder and action hero promised to clean up “the mess” in California. He took aim at what he derided as the “girlie men” in the legislature, promising to get the state’s affairs in order. It was not to be. After a bruising defeat by liberal interest groups over a series of propositions, the onetime tough guy embraced what he called “bipartisanship.” The media, particularly on the national level, cooed, but in reality the governor simply ceded initiative to the very “girlie men” - the left-leaning state legislators - that he formerly promised to rein in.

Under Schwarzenegger, notes former GOP Assemblyman Keith Richman, the state budget actually grew even faster - 10 percent annually as opposed to 7 percent - than under his spendthrift Democratic predecessor, Gray Davis.

Dan Walters, the dean of California political reporters, argues that Schwarzenegger never bothered to learn the basics of state governance. As a result, state spending, particularly on state employees and their pensions, continued with no notion that another budget crisis was looming.

The Economic Crash

The Terminator and his advisors also never understood the economic rot undermining the state. The governor assumed little could be done to preserve manufacturing, warehousing, and other high-paying blue-collar jobs in California. Instead, he bought the idea that “creative” professionals in technology, finance, and entertainment could keep the state economically vibrant.

To be sure, the big players in technology and entertainment still often keep their main offices, and sometimes their research facilities, in California. However, they also tend to locate their middle management and production jobs to more affordable, enterprise-friendly states and countries. This is one reason, notes the Milken Institute’s Ross DeVol, that tech growth has been relatively weak even during the much-ballyhooed Internet 2.0 boom.

Worst of all, the governor’s economic team did not see the danger of the state’s growing reliance on the real estate bubble. According to my colleagues at the Praxis Strategy Group and others, as much as 50 percent of the state’s job growth in the 2000s relied on an inflated property market. It worked for a time, keeping many people - investors, homeowners, construction workers, financial types - gainfully employed and the state, for a while, solvent. A better-informed governor might have known it would all unravel. Indeed, in early 2007, even as it was clear that the bubble was deflating, Schwarzenegger continued to play vaingloriously to the klieg lights, promoting California as “the harmonious state, the prosperous state, the cutting-edge state … a model not just for 21st-century American society, but the world.”

Instead of addressing the fundamental fiscal and economic problems, the governor preened for the local and national media by making California the focal point for addressing global climate change. He also proposed a gigantic $14 billion healthcare program largely funded by a state that has beleaguered smaller businesses.

Fiscal reality scuttled the healthcare plan, but business is still trying to figure out how to cope with a carbon regime faced by few of their competitors. Meanwhile, California’s unemployment is now over 7.3 percent, fourth worst in the nation, behind only Michigan, Mississippi, and Rhode Island.

In wide regions of the state - from San Diego up through the Central Valley - the only boom is in the foreclosure business. Nor are the inner-city revivals doing much better. Shining condominium towers in Oakland, L.A., and San Diego have either cut their prices or, in many cases, gone rental, a fitting tribute to an age of diminished expectations.

…and Now the Return of Governor Moonbeam?

The state’s Republicans might be expected to exploit such a record of Democratic failure but seem incapable of doing so. Since the mid-1990s and Pete Wilson’s embrace of Proposition 187, the ballot measure designed to restrict social services provided to illegal immigrants, many grassroots elements of the party have tended to demonize the immigrants who make up almost 40 percent of the workforce.

The state is already close to a minority majority; Latinos alone make up half of the current kindergarten class. Republicans could blame the Democrats for the state’s persistent fiscal crisis. They could score points against the elitist aspects of ultra-green policies, the gluttony of public employees, the prospect of higher taxes, and the more radical parts of the left’s social agenda. However, that argument must be addressed toward, not against, the state’s increasingly minority middle class.

Instead, the most probable political scenario is more of the same, or worse. The two leading candidates for governor, San Francisco Mayor Gavin Newsom and 70-year-old Attorney General Jerry Brown, are considerably to the left of and even greener than Schwarzenegger.

Brown is clearly the stronger candidate, with a demonstrated appeal to minority voters that Newsom lacks. And Brown enjoys greater name recognition and better access to the big urban land interests, Hollywood, and Silicon Valley, the main money sources of the party other than the unions. In addition, Newsom is particularly ill suited to make even Jerry Brown seem out of touch. In a campaign, Newsom will have to justify his city’s policy of shielding illegal alien felons. He has spoken publicly about fining residents up to $1,000 for failing to sort their garbage correctly, something sure to repel most Californians.

Yet a second Brown administration poses enormous risks. Although somewhat pragmatic as mayor of Oakland, Brown has become an increasingly strident apostle of Al Gore’s global warming ideology. Brown calls global warming “the most important environmental issue facing the state and the world.” He has made it clear that he hopes to use legislative and executive power to curb suburban growth and induce people to cram themselves into California’s already congested, often crime-ridden cities.

Brown also seems determined to declare a holy war against the state’s already weakened agricultural and industrial base. As attorney general, he has pledged to block a proposed northern California plant that violates green values by using plastic bottles, a policy which, if he carries it out to its logical end, will decimate almost every blue-collar and industrial industry in the state.

So is there hope for the Golden State? Perhaps, although California likely will never regain the preeminence of a quarter century ago. Brown is many things, but he is also smart and flexible, as he showed by embracing Proposition 13 after its passage in 1978. He could still find a way to push the legitimate part of the green agenda, such as expansion of renewable fuels, without forcing every carbon- consuming business or single-family homebuilder out of the state.

Finally, there is this: no place in North America enjoys California’s combination of fertility, natural beauty, and diversity. Many Californians accept high housing prices, silly regulations, and noxious lawyers as part of the price of paradise. In a country of 50 states and more than 300 million people, there should still be a niche for an exceptional place, even if it no longer can pretend to lead the nation.

Biologically Inspired Repair for Leaky Water Pipes

Friday, November 14th, 2008

The drinking-water pipe network in the United States extends more than 700,000 miles — four times the length of the national highway system. Much of the infrastructure is more than 100 years old.

It is estimated by the American Water Works Association that U.S. water utilities will need to invest $250 billion over the next 30 years to replace the aging pipes, many of which leak.

That typically involves digging up streets, which is costly. Enter a new platelet technology being tested by Yorkshire Water in the UK. It was developed by a company called Brinker, which was spun off from the University of Aberdeen. (It’s estimated that about a third of London’s drinking water is lost through leaking pipes.)

The technology is already used by the natural gas and oil industries to plug holes in leaky water pipes used to increase the pressure for extraction. Brinker says the technology’s parameters are: pressures from 2 to over 500 bars; and holes in pipes from 0.3mm to 50mm in diameter. The company says holes that big have been successfully sealed.

The platelet technology works the same way blood platelets seal a bleeding wound. They work under pressure, traveling inside a water pipe to seal the leak from within. 

The platelets are composed of materials that have passed stringent tests to ensure they don’t pose a risk to people who drink them. Testing is currently underway and the expectation is to have the technology in widespread commercial use in 2010.

What’s the spending outlook this year and next for water technologies like Brinker’s? A recent survey conducted by Changewave Research revealed the recession is weighing heavily on projected spending for water projects.

Desalination technology purchases are expected to be down by nearly 33 percent over the next 12 months, while long-term investment in infrastructure repair and replacement for pipes is holding steady or expected to attract more spending than any other water category over the next two years.

What’s more, wastewater treatment and water filtration are expected to get a bump in spending from the residual effect of water-infrastructure spending. Changewave Research’s  survey also found that the company best positioned to benefit in the water industry is General Electric.

With the expected steady investment in water-pipe replacement and repair infrastructure, the upside of Brinker’s platelet technology looks promising for a lot of leaky municipal water systems.

Another interesting water technology comes from Tongji University in Shanghai where researchers worked with Wei-xian Zhang, a professor of civil and environmental engineering at Lehigh University and recently completed a multiyear project studying how iron can be used to detoxify pollutants in industrial wastewater.
The iron, called zero valent iron because it is not oxidized, was obtained in the form of shavings or turnings from local metal-processing shops for less than 15 cents a pound.

Following a pilot test of the iron-detox approach two years ago, the Shanghai government approved a grant to construct a full-scale treatment reactor in the Taopu district.  It can process almost 16 million gallons a day of wastewater. Prior to the experiment, few people believed scrap iron could be used to clean water. –Lee Bruno

Mid-Level Ethanol Blends & Impact on Automakers

Tuesday, November 11th, 2008

Mid-level ethanol blends such as E12, E15, E20 and even as high as E40 have garnered a lot of attention lately. Mainly because ethanol producers want a quick and easy way to soak up a surplus of ethanol that will soon reach the saturation point for the current supply in the marketplace.

Under current federal law, conventional fuel cannot contain more than 10 percent ethanol, known as E10, but proponents for higher mid-level blends would like to replace the current gasoline mixture with higher levels of ethanol, which would change the fuel used in vehicles and small engines.

GM’s concerns with higher ethanol blends include the capability of our engines and fuel systems to handle them. Anecdotally, some might do fine. But there are 250 million vehicles on the road in the U.S. and only about 7 million of them are designed to handle higher ethanol blends.

and ethanol up to 85% ethanol. Conventional engines, however, are
not necessarily equipped to run on ethanol mixes greater than 15%.

In addition, there are marine and industrial engines, plus a host of outboards, lawn and garden equipment, motorcycles and various off-road vehicles that would be impacted as well.  None of this equipment was designed to use mid-level ethanol blends and some was not designed to use ethanol at all.

Higher ethanol blends run hotter in many non-flex-fuel equipped vehicles and virtually all of the non-automotive equipment, and the way this process works is that a small change in temperature produces a very large change in behavior.

The biggest question is long-term durability.  The only durability study conducted on these fuels to date was done for the Australian Department of the Environment (ref. Fuel Quality Publications, Australian Government).

It found corrosion, seal attack, and catalyst damage due to the engine control system’s failure to adapt to the ethanol and using the wrong mixture at high power.

When the U.S. Department of Energy (DOE) released its preliminary test findings on E15 and E20 last month, little was said about six of 13 vehicles tested exhibiting catalyst overheating.  A damaged catalyst is less effective at eliminating pollutants and allows increased tailpipe pollution.  The leaner fuel mixture – ethanol is 35 percent oxygen – also lead to drivability and operability issues in older vehicles and non-automotive equipment.

GM is working with other automakers, the oil industry, DOE and EPA to develop and execute test programs to determine and document the effects of these higher blends on the existing fleet.  This work takes time.

At GM, we think E85 ethanol is the best alternative to petroleum in the near term, but in order for ethanol, or any alternative fuel, to succeed it needs the good will of the public and government behind it.  Prematurely implementing a higher ethanol blend that damages the gasoline-fueled equipment could cause irreparable harm to ethanol’s reputation.  And ethanol took a big hit with the Australian public following the introduction of mid-level blends in limited areas.  This is what prompted the Australian Department of the Environment to fund the E20 study performed by Orbital Engine Co.

GM has worked to expand the E85 infrastructure in this country, assisting more than 300 stations in 15 states with securing state and other grants to help offset the cost of installing E85 pumps.  We are now implementing a partnership with the National Governors Association to help 10 states grow their E85 infrastructure (ref. States to Enhance Access to E85 Fueling Stations, National Governors Association).

Our commitment to E85 includes making 50 percent of our vehicles capable of running on gasoline, E85 or any combination of the two by 2012, provided there is sufficient infrastructure in place.  Let’s be clear about the math: No combination of mid-level blends will add up to enough ethanol use to meet the Renewable Fuels Standard that calls for 36 billion gallons of ethanol a year by 2022.

E85, which is an alternative fuel vs. a fuel additive, is a choice we provide free to GM customers.  We know choice can work, as it has in Brazil and Sweden, where governments required fueling infrastructure to support FFVs.  Customers typically choose between ethanol and gasoline, depending on which is the best deal.

The bottom line is GM supports and encourages greater ethanol fuel availability for our flex-fuel vehicles, but we are concerned about customers misfueling conventional vehicles by using fuels containing more than 10 percent ethanol.  The long-term durability of higher ethanol blends in conventional engines needs to be tested thoroughly because advocates are proposing to change gasoline for all of us, forever.

Smart Cleantech Catalysts

Thursday, November 6th, 2008

The problem for scientists and engineers has been that in order to tune a catalyst to do what is desired, you need to know how it adapts during a reaction. Trouble is, watching catalysts in action has escaped the reach of scientists until now.

With the aid of powerful spectroscopy technology, U.S. Department of Energy Lawrence Berkeley National Laboratory scientists observed catalysts restructuring themselves in response to various gases swirling around them.

The spectroscopy helps provide a window into these reactions for tuning catalysts. These insights are expected to help improve pollution control as well as fuel cell technologies. Smarter catalysts hold promise for removing toxins from water and helping feed hydrogen fuel cells.

Scientists used an advanced spectroscopy system at Berkeley Lab’s Advanced Light Source to study nanoparticles composed of two catalytic metals.

In the lab, Gabor Somorjai, a researcher who holds joint appointments with the Berkeley Lab’s Materials Sciences Division and UC Berkeley’s department of chemistry, teamed up with spectroscopy expert Miquel Salmeron of Berkeley Lab’s Materials Sciences Division and UC Berkeley’s department of materials sciences and engineering.

The two scientists observed how particles changed their composition in the presence of different reactants. Prior to these observations, scientists had to rely on snapshots of catalysts taken before and after a reaction.

The scientists said that the observations gleaned from watching catalysts change in real time is extremely valuable in helping design smart catalysts that change as a reaction evolves.

Armed with this information, scientists think they can develop nanoparticle catalysts and reactants tailored to most efficiently yield a product, whether it’s gasoline or cleaner emissions.

Epic Correction Leads to Depressed Solar Sector

Wednesday, November 5th, 2008

How epic has this correction been? The answer is worse than the 1987 programmatic crash (S&P -32%) but not as bad, to-date, as the 1973 oil crisis (S&P -48%) or the dot-com bubble (S&P -49%). For an excellent graphic of these events and the current housing bubble (S&P -45%) visit CalculatedRisk.com. In this graph each of the indices starts at the same point on the top of the vertical axis, which represents the percentage amount of drop in index value. With the horizontal axis representing time, it can be seen that while the percentage drop of the S&P 500 is not quite as severe as in the case of the corrections of ‘73 or ‘00, those corrections took 2-3 years to hit bottom. We are less than one year into this correction and the S&P is down 44%.

For sustainable energy the correction to-date has been even more severe. Our graph from the October 7, 2007 S&P 500 peak to the end of October 2008 shows the changes to the four sectors we have been tracking since the S&P peak. At their minimums the four indices were down between 65 - 80%.

So what am I optimistic about? Simple, I’m optimistic the sustainable energy industry will continue to exist and at some point prices get so low that the stocks represent attactive buys. I think this is particularly true for solar as the statistics below show for 10 of the US traded companies I track in the Camino SOLAR index (detail here).

SOLAR growth rates would have to slow dramatically to make the companies overpriced at current levels. Even if their earnings growth slows by a factor of 4 these ten companies would still be fairly priced. And I don’t see many reasons to expect such a slowing. Modules prices are expected to fall which should boast sales and improve customer ROI. Retail electric prices are virtually unaffected by oil prices in many economies so the basic economic benefit of solar isn’t going away. Subsidies are locked in in the US. Financing should be available with the massive governmental pushes to create liquidity while lowering rates. And the technology continues to improve further driving down costs and improving solar’s competitive position.

There may be other bargins in the sustainable energy sector but the solar sector is a good place to start with plenty of potential investment targets.

Global Warming: Why cut one 3,000th of a Degree?

Wednesday, November 5th, 2008

Global warming is seen everywhere as one of the most important issues. From the EU to the G8, leaders trip over one another to affirm their commitment to cutting CO2 to heal the world. What they do not often acknowledge - in part because it would lose them support - is that the solutions proffered are incredibly costly and will end up doing amazingly little good, even in a century’s time. This is the truly inconvenient truth of the politics of global warming.

Let’s be clear. I’m not contesting the existence of global warming. Doing so is silly, given the clear and strong results from the UN climate panel. Global warming will most probably warm the planet by between 1.6 and 3.8C above current temperatures by the end of the century. The total cost of the consequences of this warming is estimated by William Nordhaus, of Yale University, to be $15 trillion.

However, we need to keep our cool: global warming’s total cost will be only about one half of 1 per cent of the net worth of the 21st century; that is the current worth of all the wealth projected to be generated in this century. Panicking is unlikely to lead to sensible policies. It could lead to exorbitantly expensive policies, which will do great harm.

Delivering better nutrition, education, and
fighting disease all yield far better returns.

Many of the proffered global warming policies are designed to help politicians bathe in the warm glow of good intentions, with little or no regard to the mounting costs and infinitesimal benefits.
 
It is a well-rehearsed point that the Kyoto Protocol was a terribly inefficient, hugely costly way to do virtually no good. Even if every industrialised country, including the United States, had accepted the protocol, and everyone had lived up to its requirements for the entire century, it would have had virtually no impact, even a hundred years from now. It would reduce the global temperature increase by an immeasurable 0.15C by the year 2100. The cost of implementing Kyoto, taking the average figure from the various top macroeconomic models, would have been almost £100 billion annually for the rest of the century.

The US declined to sign up to Kyoto and many countries, including Spain, Japan, Canada, and Greece, have had a hard time living up to their pledges. It is likely that the total reduction in carbon emissions will be less than 5 per cent of what Kyoto promised.

Yet the EU and others advocate that Kyoto-style policies are still right, only that much more than Kyoto is needed. The EU has promised to cut its emissions by 20 per cent by 2020, through a 20 per cent increase in renewables. There seems to be no better reason for this decision than that 20 and 20 in 2020 sounds good. Gordon Brown has wholeheartedly backed the plan, which includes making a dramatic increase in renewables - mainly 3,500 wind turbines in the North Sea.

The British Government estimates the cumulative carbon saving from all its plans at somewhere between 950 and 1,100 million tonnes of CO2 by 2030. The Department for Business will not give a figure beyond that timeframe but, given that wind turbines have a lifetime of about two decades, this seems the relevant cumulative reduction given the investment. The department confirms that the total investment from public and private sources into renewables will be about £100 billion.

Computer modelling - using DICE (dynamic integrated model of climate and the economy) - shows that the net effect of the UK renewables effort is impossibly tiny. The temperature increase by 2100 without Mr Brown’s plan would have been 2.4536181C. With the best-case scenario the huge UK effort means that the temperature at the end of the century would be 2.4532342C. The effect is a difference of about 0.00038C - or about one three-thousandth of a degree in a hundred years. This is the equivalent of delaying the temperature increase by the end of the century by a little less than a week.

Of course, these numbers are way too precise: different models and assumptions would give somewhat different results. Yet because we are talking about relative change, the absolute climate sensitivity of the particular model matters very little. Thus the order of magnitude is robust and indicates an astonishingly small effect for a very large cost.

If one imagines that the reductions could be sustained across the century (which presumably would also call for five repeated investments of hundreds of billions of pounds), the effect is still very small - a temperature reduction of about one six-hundredth of a degree.

Using the latest academic meta-study by Professor Richard Tol we can calculate that cutting 1,100 million tonnes of CO2 would create benefits worth £4 billion in terms of the impact on agriculture, forestry, preventing deaths from heat and cold, disease and unmanaged eco-systems. At a cost of £100 billion, the investment involves paying £1 to do less than 4p worth of good.

The UK emits about 2 per cent of global CO2. Thus we could imagine the world as composed of 50 UKs, each emitting one fiftieth of the carbon. If all 50 of our “UKs” paid a £100 billion to reduce temperatures by one three-thousandth of a degree in 100 years, the result would be still be trivial: one sixtieth of a degree by the end of the century. Costs would most probably increase similarly, fiftyfold to £5,000 billion. This amazing sum would simply postpone global warming and its problems by a mere 11 months by the end of the century.

The cost of £5,000 billion is equivalent to a hundredfold increase in global donations to developing countries. To make a simple comparison, the UN estimates that for about £40 billion annually, we could solve all major basic problems in the world - we could give clean drinking water, sanitation, basic education and healthcare to every person in the world. But instead we are spending a fortune achieving almost nothing.

Of course, we shouldn’t ignore global warming. But instead of trying to cut CO2 emissions, we should focus on dramatically increasing the funding into energy research and development. What matters is getting low-cost low-carbon technology available faster. If the price of renewable energy dropped below the cost of fossil fuels by mid-century, everyone - including China and India - would switch to the greener alternatives. Work done by the Copenhagen Consensus suggests that such a policy could be 300 times better for the world than the UK approach. We could end up doing more than £11 worth of good for each £1 invested. While we would do much more good in total terms, the cost would also be much lower, and hence much more likely to be implemented.

When it comes to climate, we have to come to our senses. Yes, global warming is real and caused by human beings, but it doesn’t mean we should panic in our policy decisions. We need to do the right thing - and invest in discovering and developing new low-carbon technology.
