Bioengineering is coming fast.

Tuesday, October 30th, 2012

An interesting article from bbc explains how concrete treated with a species of bacillus can “heal concrete” cracks by making more limestone.

Experimental concrete that patches up cracks by itself is to undergo outdoor testing.

The concrete contains limestone-producing bacteria, which are activated by corrosive rainwater working its way into the structure.

The new material could potentially increase the service life of the concrete – with considerable cost savings as a result.

The work is taking place at Delft Technical University, the Netherlands.

It is the brainchild of microbiologist Henk Jonkers and concrete technologist Eric Schlangen.

If all goes well, Dr Jonkers says they could start the process of commercialising the system in 2-3 years.

From the article, it sounds like these are not engineered bacteria but engineering may increase yield.

“Micro-cracks” are an expected part of the hardening process and do not directly cause strength loss. Fractures with a width of about 0.2mm are allowed under norms used by the concrete industry.

But over time, water – along with aggressive chemicals in it – gets into these cracks and corrodes the concrete.

“For durability reasons – in order to improve the service life of the construction – it is important to get these micro-cracks healed,” Dr Jonkers told BBC News.

Bacterial spores and the nutrients they will need to feed on are added as granules into the concrete mix. But water is the missing ingredient required for the microbes to grow. Concrete is the world’s most popular building material, but cracking is a problem

So the spores remain dormant until rainwater works its way into the cracks and activates them. The harmless bacteria – belonging to the Bacillus genus – then feed on the nutrients to produce limestone.

The bacterial food incorporated into the healing agent is calcium lactate – a component of milk. The microbes used in the granules are able to tolerate the highly alkaline environment of the concrete.

The cost will be high per unit but in the overall scheme of things, reduction in maintenance and longer functional life will dwarf cost issues.

Far out there.

Once again, Craig Venter is looking for new challenges. The latest may be Martian DNA.

I have thought for some time that life on Mars is going to consist of microorganisms and be buried several feet below the surface of the planet soil. I have even blogged about it before.

Now, there is a possibility of a nucleotide sequencer that could go to Mars on the next probe in 2018.

In what could become a race for the first extraterrestrial genome, researcher J. Craig Venter said Tuesday that his Maryland academic institute and his company, Synthetic Genomics, would develop a machine capable of sequencing and beaming back DNA data from the planet.

Separately, Jonathan Rothberg, founder of Ion Torrent, a DNA sequencing company, is collaborating on an effort to equip his company’s “Personal Genome Machine” for a similar task.

“We want to make sure an Ion Torrent goes to Mars,” Rothberg told Technology Review.

Although neither team yet has a berth on a Mars rocket, their plans reflect the belief that the simplest way to prove there is life on Mars is to send a DNA sequencing machine.

“There will be DNA life forms there,” Venter predicted Tuesday in New York, where he was speaking at the Wired Health Conference.

Venter said researchers working with him have already begun tests at a Mars-like site in the Mojave Desert. Their goal, he said, is to demonstrate a machine capable of autonomously isolating microbes from soil, sequencing their DNA, and then transmitting the information to a remote computer, as would be required on an unmanned Mars mission. Heather Kowalski, a spokeswoman for Venter, confirmed the existence of the project but said the prototype system was “not yet 100 percent robotic.”

Doing this on Mars would avoid the problem of contamination by earth organisms. New life forms that don’t use DNA might be a problem but most people who have thought about this believe that DNA is the genetic material of all life forms. Of course, protein, which may have been the original genetic material on earth could also be the Martian equivalent.

We are starting to see commercial spacecraft develop and one was used to reach the international space station recently. A Mars mission is another order of complexity but by 2018, it may be an option.

UPDATE: A new report describes obtaining natural gas (methane) from coal using bacteria or archea.

Many coal beds contain large amounts of methane that can be harvested by drilling wells. In recent decades, researchers have demonstrated that a large fraction of the natural gas found in the coal beds is produced by naturally occurring microörganisms that feed on coal, and they have found ways to stimulate the microbes to produce more methane. Luca Technologies, based in Golden, Colorado, is using this approach to increase production from coal beds with existing methane wells. Another company, Next Fuel, based in Sheridan, Wyoming, recently showed that it could use similar technology to produce methane from coal beds that didn’t already have methane in them, raising the possibility that vast amounts of coal that’s currently too expensive to mine could be converted into natural gas.

What will we find on Mars that might be an analogous system ?

Craig Venter and biofuels

Monday, October 15th, 2012

Biofuels have gotten somewhat of a bad rep with conservatives because they are linked to Obama’s green energy boondoggles. Steve Hayward, at Powerline, thinks that success will be enough to turn the greenies against them. First they will be genetically engineered and will be developed by “Big Oil” partnering with entrepreneurs like Craig Venter who deciphered the human genome with private resources. He was in competition with the government funded “Human Genome Project.” My book review of Venter’s autobiography is here.

Venter does well in explaining his research and the article follows it well.

Venter said in an interview, “It’s pretty obvious that there’s nothing in the natural world to make the levels that are needed,” and he pointed to algae oil yield volumes needing approximately 20,000 gallons per acre equivalent of algae.

Venter and his research team, of course, in spring 2010, successfully created the first synthetic bacterial cell, which was controlled completely by a synthetic genome. Or as Venter explained it in his recent interview, as the first cell “to have a computer for a parent,” or “designed DNA on a living system.” Venter now says he has increasingly realized that a fully synthetic cell is the way to go to create competitive algae fuel. When it comes to tweaking naturally occurring algae cells, he says, “you’ll never get there with that. We need a fundamental change to how we approach all this.”

This will be enough to antagonize the Luddite Greenies who are ideologically hostile to genetic engineering. Some writers are already predicting problems.

Venter, the first mapper of the human genome and creator of the first synthetic cell (pictured above), said his scientific team and ExxonMobil have failed to find naturally occurring algae strains that can be converted into a commercial-scale biofuel. ExxonMobil and Venter’s La Jolla, Ca.-based Synthetic Genomics Inc., or SGI, continue to attempt to manipulate natural algae, but he said he already sees the answer elsewhere — in the creation of a man-made strain. “I believe that a fully synthetic cell approach will be the best way to get to a truly disruptive change,” Venter told me in an email exchange.

Venter made his remarks before a conference this week on the future of energy at the New America Foundation in Washington, D.C., and in subsequent emailed replies to questions.

When announced in July 2009, the Venter-ExxonMobil alliance of colossals attracted wide publicity. It called for ExxonMobil to spend up to $600 million if publicly undisclosed milestones were reached in the lab. The Wall Street Journal said the partnership might signal “a coming of age” for algae biofuel. Greenbang fretted that the alliance might actually prove “unholy,” but not Gigaom, which said it could be “algae’s big break.”

The terms of the alliance omit the fully synthetic approach that Venter is now advocating, so he is conducting “an ongoing dialog” with Exxon about a new agreement, he said. He appeared to suggest that such a new compact would require more Exxon investment.

If I were in charge of investing in alternate energy research, I would take what Venter says very seriously.

I assume that our skill set in this area has been one of the attractions for Exxon to work with us. Our success at building the first synthetic cell is only from last year and had not been achieved when we formed the agreement between SGI and Exxon. So I would say it is an ongoing dialog.

The future lies with algae and modifications of coal. Ethanol is a dead end. Venter is not the only one interested.

One of the dangers of using the synthetic algae cells is the fear that the cells could somehow be let loose on the outside world, which Venter admits could wreak havoc like turning the oceans into a sea of lipids. But Venter says that designing an organism that has self-destructive properties (it can’t live outside a lab, or it dies with a certain time period) could contain such an organism.

Algae oil company Solazyme, went public this year, and plans to commercialize its algae fuel in the coming years. Solazyme tweaks existing efficient algal strains and grows its designer algae in fermentation tanks without sunlight by feeding it sugar and then using existing industrial equipment extracts the oil. Solazyme’s stock is trading a bit under $10, way down from its IPO price of $18.

I would bet on Venter, first of all because he thinks in terms of private, profit making business. His record is pretty impressive and he has hired a lot of the world’s experienced scientists. I have previously written a number of blog posts on related topics, here, and here, and here, and here.

It’s interesting that the Titanic is being eaten by “Rusticles” that that are eating the iron in the hull. Bacteria that eat iron in an oxygen-free environment are only one of the marvels that are being discovered in the depths of the ocean and in hot vents in volcanic pools.

The coming energy crisis

Friday, January 14th, 2011

The Obama administration is still in the throes of global warming mentality. They have cancelled leases for oil and gas in the huge deposits in western states like Montana. The vast boom going on just to the north in Alberta has not impressed Interior Secretary Salazar. They want to take millions of acres out of the energy search by naming them wilderness, just as Bill Clinton created a huge wilderness area out of good potential energy fields at the end of his administration. They have not made nuclear power plants any easier to build. The Gulf oil leases are still blocked and the moratorium, while allegedly ended, continues in a slow down. The only energy and his acolytes are interested in is “renewable” such as wind and sun. These are boutique power sources and even these are being blocked by Democratic politicians.

But the project is hardly shovel ready. Several regulatory hurdles remain, and opponents of the wind farm have vowed to go to court, potentially stalling Cape Wind for several more years.

For years the Cape Wind project has been the focusof pitched battles splitting politicians and environmental groups. While some environmentalists are prepared to go to court to stop the project, other major groups, including the Sierra Club and Greenpeace, support it.

Senator Edward M. Kennedy of Massachusetts, whose family compound overlooks Nantucket Sound and who died last year, had opposed the project, saying it was a giveaway to a private developer.

It has taken nine years to get this far. In California, another lefty state, a big solar project is being fought by enviros and Democrats. I wonder if the left wants any energy developed. It seems insane but we are getting very close to a tipping point when there will not be time to build new projects and find more oil and gas.

The Democrats, and the vast array of “activists” whom they enable, have demonstrated hostility to all practical forms of energy production and distribution. This is not just a matter of oil & gas drilling: as we have discussed many times on this blog, the U.S. electrical system faces a problematic future. There is every likelihood that, under a Democratic administration/Congress:

a)The building of new coal plants would go from “difficult” to “impossible”
b)The building of nuclear plants would continue to be virtually impossible
c)Even the building of new natural-gas-fired plants would be severely delayed by environmental lawsuits and regulatory maneuvering based on the CO2-is-a-pollutant theory.

Solar and wind, beloved of Democrats, have their uses, but they also have their limitations. I see no evidence that either Obama or the Dem Congressional leadership has any interest in understanding the technical and economic factors that govern the extent to which these technologies can be practically employed. The intermittent nature of wind and usable sun, the difficulty of storing electricity, the supply-chain constraints which govern the large-scale introduction of any new technology–there is much less interest in these things than in the glib repetition of catch-phrases. And even the use of environmentally-blessed technologies will be greatly inhibited by environmentalist protests against the transmission lines required to connect these systems to the cities that need their power. These activists would, of course, gain great impetus from a Democratic administration.

Obama talks a lot about the middle class. The existence of a large and affluent middle class is enabled by widely available and reasonably priced energy, especially electricity. If electric rates are driven up by a factor of 2X or 3X, as is entirely possible with Democratic policies, there will be not only a direct effect on consumers, but an effect on virtually all workers as U.S. businesses–especially manufacturing businesses but also things like data centers–become less competitive.

Lenin once remarked that “Communism is Soviet power plus electrification.” Our present “progressives” seem more interested in de-electrification. Where the New Deal (and the Soviets) wanted to build hydroelectric dams, today’s “progressives” are, for the most part, more interested in destroying them.

Remember, electrical infrastructure is a long-leadtime item, and if we dig outselves into a deep hole in this matter, it will take a long, long time to dig ourselves out..

That was written in 2008. Read the whole thing. It did a pretty good job of predicting the Obama administration’s policies.

The crisis of the intellectual

Saturday, December 11th, 2010

I was directed to an excellent post by Walter Russell Mead today. It is on the subject of the American social model and the coming era of tumultuous social unrest as the old welfare state model collapses. Europe is already seeing this collapse as nations like Greece face bankruptcy and England deals with the consequences of severe cutbacks in social spending to avoid it.

The US is facing similar economic consequences if the level of spending is not addressed soon. The 2010 elections show that the people recognize the crisis but the “political class” seems less concerned.

“It’s telling to note that while 65% of mainstream voters believe cutting spending is more important, 72% of the Political Class say the primary emphasis should be on deficit reduction,” Rasmussen said.

“Deficit reduction” is code for raising taxes. Spending is heavily embedded in the culture of the political class.

Mead is concerned that the intellectual demographic, those with advanced degrees and careers denominated by thinking rather than doing, is unable to cope with the new situation.

There’s a lot of work ahead to enable the United States to meet the coming challenges. I’m reasonably confident that we remain the best placed large society on earth to make the right moves. Our culture of enterprise and risk-taking is still strong; a critical mass of Americans still have the values and the characteristics that helped us overcome the challenges of the last two hundred years.

But when I look at the problems we face, I worry. It’s not just that some of our cultural strengths are eroding as both the financial and intellectual elites rush to shed many of the values that made the country great. And it’s not the deficit: we can and will deal with that if we get our policies and politics right. And it’s certainly not the international competition: our geopolitical advantages remain overwhelming and China, India and the EU all face challenges even more daunting than ours and they lack our long tradition of successful, radical but peaceful reform and renewal.

No, what worries me most today is the state of the people who should be the natural leaders of the next American transformation: our intellectuals and professionals. Not all of them, I hasten to say: the United States is still rich in great scholars and daring thinkers. A few of them even blog.

His concern is that the intellectuals seem caught in a mind set that goes back to the 19th century and the Progressive Era.

Since the late nineteenth century most intellectuals have identified progress with the advance of the bureaucratic, redistributionist and administrative state. The government, guided by credentialed intellectuals with scientific training and values, would lead society through the economic and political perils of the day. An ever more powerful state would play an ever larger role in achieving ever greater degrees of affluence and stability for the population at large, redistributing wealth to provide basic sustenance and justice to the poor. The social mission of intellectuals was to build political support for the development of the new order, to provide enlightened guidance based on rational and scientific thought to policymakers, to administer the state through a merit based civil service, and to train new generations of managers and administrators.

It’s interesting that one of the comments, a lengthy one, exactly restates this issue but supports this model and argues with Mead that it is still superior.

Second, there are the related questions of interest and class. Most intellectuals today still live in a guild economy. The learned professions – lawyers, doctors, university professors, the clergy of most mainline denominations, and (aspirationally anyway) school teachers and journalists – are organized in modern day versions of the medieval guilds. Membership in the guilds is restricted, and the self-regulated guilds do their best to uphold an ideal of service and fairness and also to defend the economic interests of the members. The culture and structure of the learned professions shape the world view of most American intellectuals today, but high on the list of necessary changes our society must make is the restructuring and in many cases the destruction of the guilds. Just as the industrial revolution broke up the manufacturing guilds, the information revolution today is breaking up the knowledge guilds.

He goes on to criticize medicine as a guild but I think he is unaware of the rapid changes going on in medicine today. The image of the family GP is quickly shifting to the multispecialty group with primary care provided by nurse practitioners and physician assistants. Those who want a personal relationship with a primary care physician, or even a favored specialist, will increasingly be required to pay cash for the privilege as many doctors who want to continue this model of practice are dropping out of insurance and Medicare contracts because of the micromanagement and poor reimbursement.

In most of our learned professions and knowledge guilds today, promotion is linked to the needs and aspirations of the guild rather than to society at large. Promotion in the academy is almost universally linked to the production of ever more specialized, theory-rich (and, outside the natural sciences, too often application-poor) texts, pulling the discourse in one discipline after another into increasingly self-referential black holes. We suffer from ‘runaway guilds’: costs skyrocket in medicine, the civil service, education and the law in part because the imperatives of the guilds and the interests of their members too often triumph over the needs and interests of the wider society.

Almost everywhere one looks in American intellectual institutions there is a hypertrophy of the theoretical, galloping credentialism and a withering of the real. In literature, critics and theoreticians erect increasingly complex structures of interpretation and reflection – while the general audience for good literature diminishes from year to year. We are moving towards a society in which a tiny but very well credentialed minority obsessively produces arcane and self referential (but carefully peer reviewed) theory about texts that nobody reads.

Once again, costs in medicine are a subject by themselves but the solution does not lie in controlling doctors incomes. With respect to the academic institutions, I have personal experience here and will describe some of it. The Humanities have been hollowed out by a trend to both politicize and to leave the subject behind as “critical thinking” goes on to analysis that has little to do with it. The Sokol Hoax is but one example.

The Sokal affair (also known as Sokal’s hoax) was a publishing hoax perpetrated by Alan Sokal, a physics professor at New York University. In 1996, Sokal submitted an article to Social Text, an academic journal of postmodern cultural studies. The submission was an experiment to test the magazine’s intellectual rigor and, specifically, to learn if such a journal would “publish an article liberally salted with nonsense if it (a) sounded good and (b) flattered the editors’ ideological preconceptions.”[1]

The hoax precipitated a furor but did not result in much improvement in such publications. My daughter had personal experience when her freshman courses in English Composition and American History Since 1877 both contained numerous examples of political and “social justice” alteration of the subject matter. For example, she was taught that the pioneers in the west survived by “learning to live like the Native Americans.” The fact is that the pioneers were mostly farmers and ranchers and the Native American tribes of the southwest were hunter gatherer societies who did not use agriculture or animal husbandry. She was also taught that the “Silent Majority” of the 1960s were white people who rejected the Civil Rights Act of 1964. Thus they were racists. Even Wikipedia, no conservative source, disagrees:

The term was popularized (though not first used) by U.S. President Richard Nixon in a November 3, 1969, speech in which he said, “And so tonight—to you, the great silent majority of my fellow Americans—I ask for your support.”[1] In this usage it referred to those Americans who did not join in the large demonstrations against the Vietnam War at the time, who did not join in the counterculture, and who did not participate in public discourse. Nixon along with many others saw this group as being overshadowed in the media by the more vocal minority.

She has since transferred to another college.

The foundational assumptions of American intellectuals as a group are firmly based on the assumptions of the progressive state and the Blue Social Model. Those who run our government agencies, our universities, our foundations, our mainstream media outlets and other key institutions cannot at this point look the future in the face. The world is moving in ways so opposed to their most hallowed assumptions that they simply cannot make sense of it. They resist blindly and uncreatively and, unable to appreciate the extraordinary prospects for human liberation that this change can bring, they are incapable of creative and innovative response.

I think this is the source of the “media bias” so prominently referred to by the Right and by many who are not politically focused. This is why talk radio and Fox News have been such huge successes to the consternation of the political class and their supporters. Charles Krauthammer famously said, “Rupert Murdoch (owner of Fox News) found a niche market that contained 50% of the population.”

The Tea Parties are another manifestation of the frustration of the general population with the political class but also with the intellectual class that seems to be wedded to the first. The university community is, at least in the non-science segment of it, to be increasingly isolated from the concerns of the society that supports them. CalTech has for many years had a Humanities program to expose science and engineering students to culture. Unfortunately, a student in a large university will find much less culture and much more politics in Humanities departments these days.

A couple of other blog posts are worth reading on this subject. One is here and the other is here. They are both worth reading in full.

Brave New World

Tuesday, November 16th, 2010

UPDATE: More on TSA sexual molestation.

There is building resistance to the new body scanners being used at airports. The response of Janet Napolitano is typical of clueless progressives in power. More of her idiocy here.

when Janet Incompetano (as Mark Steyn calls her) was asked if Muslim women sporting hijabs would have to go through the same full-body pat downs, she equivocated and said, “adjustments will be made where they need to be made” and “With respect to that particular issue, I think there will be more to come.”

And more wisdom from Big Sis:

But, she said, “if there are adjustments we need to make to these procedures as we move forward, we have an open ear. We will listen.”
She added that “if people want to travel by some other means,” they have that right.

I’m sure the airlines will be pleased to hear that. In fact, there is an alternative.

The 2001 law creating the TSA gave airports the right to opt out of the TSA program in favor of private screeners after a two-year period. Now, with the TSA engulfed in controversy and hated by millions of weary and sometimes humiliated travelers, Rep. John Mica, the Republican who will soon be chairman of the House Committee on Transportation and Infrastructure, is reminding airports that they have a choice.

It will be interesting to see how this plays out. There is growing resistance to the high handedness of the TSA.

There’s some really deep feeling brewing out there about the TSA’s newly intensified searches of airline passengers. I’m wondering what potential this very particular issue has for skewing politics more generally.

Think about why this issue has such a strong emotional impact: The government wants to see you naked or grope your genitals. It is conditioning an important aspect of personal freedom — flying in airplanes — on your resigning yourself — and your children — to sexual assault. I was chatting with someone the other day who seemed more angry about this than any other political issue.

This is more big government reaching into every aspect of life, even your underwear. The most ridiculous aspect of this is the searching of the pilots. Pilots are starting to rebel and I don’t blame them a bit. Why would a pilot need a bomb when he is in control of the airplane?

Cyberwarfare

Sunday, September 26th, 2010

We may be entering an era when cyberwar is a real threat, at least to some. I was a computer programmer in 1958-59 but that is the stone age of computing. The machine I programmed was An IBM 650 which was so primitive that it did not use hexadecimal code. This was even before FORTRAN was written so I claim no current expertise. Later, after medical school, I took some computer science courses and learned to program in Pascal and C. Still later, I learned Visual Basic but never got very far in C++ so I am pretty much a neophyte in Object Oriented Programming. The term, often abbreviated to OOP, is a way of creating small pieces of code that can be reused over and over without rewriting it and the attendant risk of error. It is also faster. This also applies to modular programming and the differences are explained in the wiki entry.

It now appears that a new “worm” has been created by someone that is capable of attacking the Iranian nuclear program. Roger Simon is the only one I have seen so far discussing it and its implications. This involves small devices called PLCs, or “Programmable Logic Controllers” some of which run your washing machine. They are the heart of computer controlled machinery, such as the 30,000 Iranian centrifuges that are purifying Uranium 235. What if all those 30,000 centrifuges went crazy, spinning so fast that they self destructed ?

This brings up the subject of Stuxnet, a computer “worm.” It attacks one specific system, the Siemens company’s SCADA systems. It happens that Siemens designed and built the SCADA systems that run its nuclear program. What a coincidence !

Has the war with Iran already begun ? Maybe.

But just as television news was transformed by technology before the Iranian Revolution in 1979, and politics was transformed by social networking before it appeared that Twitter would bring about a second Iranian Revolution, process and progress need crystallizing events, where the political and cultural significance of technological innovation becomes indisputable.

Such a moment came in July with the discovery of a worm known as Stuxnet, which sought out a particular version of the Siemens’ SCADA (supervisory control and data acquisition) systems that control power grids and industrial plants. According to Ralph Langner, an expert in industrial control systems who published a study of the worm last week, Stuxnet was capable of taking over SCADA controls in order to deliver a kinetic attack by causing critical systems to physically malfunction. The systems infected weren’t randomly targeted: a majority are in Iran.

It’s an interesting idea. A lot of Windows 7 code was written by Israeli engineers. Maybe their target is more than the nuclear program.

Stuxnet is an even more dramatic transformational event: warfare is never going to be the same, at least while the underlying protocols governing the Internet create these kinds of systemic vulnerabilities. But even if there was agreement to rewrite these protocols starting tomorrow, such a project would take a decade. So, let the damage assessment begin. Who knows? By demonstrating how Iran could so very easily experience a Chernobyl-like catastrophe, or the entire destruction of its conventional energy grid, the first round of the “war” may have already been won.

Unfortunately, the Chinese have been working very hard at the same sort of thing and we had a determined cyberattack on the Pentagon e-mail system two years ago. This may be what war looks like in the future.

UPDATE: Some body is noticing.

Working with tools.

Sunday, June 27th, 2010

UPDATE: It now appears that a plumber in Kansas has provided a major design improvement to the BP oil well cap. He designed a cap using a flange arrangement similar to that used in high pressure hotel sewage lines. Once again, American ingenuity to the rescue as the tool user saves all the PhDs from their mishap.

I have previously posted my concern about the low status of manual arts in the educational and vocational fields in this country. This also applies to science but to a lesser degree. That previous post was obviously prior to the encounter between Barack Obama and Joe the Plumber.

One major point is the fact that Joe is making $250,000 a year at that point. How many law school graduates made that much in 2008?

Even in the field of innovation, it does not require a PhD to innovate in design or manufacturing. The basic problem, to me, seems to be the lack of manual skills with tools. People who make things, or can fix things, are the bedrock of a society that needs to design and manufacture quality objects. There is even a connection to the ability to do science. I wonder how many engineers cannot take apart and reassemble the things they design or work on. The same applies to surgery. Manual dexterity should be a basic requirement for the surgeon.

Today, there are a lot of unemployed people with useless degrees who would be better off learning plumbing or auto repair. In World War II, we benefited from the technical skills of the American soldiers who had learned to work with tools and many of whom could fix cars. The solution to the hedgerows of Normandy was an American army sergeant who devised a hedgerow cutter for the front of the Sherman tank. His name was Curtis G Culin and he was one of the heroes of World War II.

Dwight D. Eisenhower as President of the United States, in a January 10, 1961, speech to the American Society of Mechanical Engineers:
There was a little sergeant. His name was Culin, and he had an idea. And his idea was that we could fasten knives, great big steel knives in front of these tanks, and as they came along they would cut off these banks right at ground level – they would go through on the level keel – would carry with themselves a little bit of camouflage for a while. And this idea was brought to the captain, to the major, to the colonel, and it got high enough that somebody did something about it — and that was General Bradley — and he did it very quickly. Because this seemed like a crazy idea, they did not even go to the engineers very fast, because they were afraid of the technical advice, and then someone did have a big questions, “Where are you going to find the steel for all this thing?” Well now, happily the Germans tried to keep us from going on the beaches with great steel “chevaux de fries” – big crosses, there were all big bars of steel down on the beach where the Germans left it. And he got it – got these things sharpened up – and it worked fine. The biggest and happiest group I suppose in all the Allied Armies that night were those that knew that this thing worked. And it worked beautifully.

One of the reasons I like Neville Shute’s novels is because he has that theme in several of them. One, titled “Round the Bend” has as its theme the development of a new religion among men who work on airplanes. It is set in Asia and concerns the religions of Asia such as Islam, Hinduism and Buddhism. The chief character is an airplane mechanic who teaches other mechanics that to do a careful, flawless job in working on an airplane is the same as praying. His interpretation of Islam (The novel was written in 1951) becomes extremely popular in the Persian Gulf region as the imams see this as a new view of religion that attracts the young men who have become interested in mechanics and science and have drifted away from traditional life. His new creed is equally popular with Buddhists and Hundus, all of them aircraft mechanics and pilots. The resulting increase in quality of the work is appreciated by the airlines and he becomes a cult figure.

Like many of Shute’s novels, the engineer, even without a degree, is the hero. I wish we had more of this. Shute knew what he was writing about as he was a successful aeronautical engineer who had owned his own company. I titled my other post, The Manual LIfe. I wish it was more appreciated.
