An Open Letter In Response to Stephen H. Unger’s Essay “Unwanted Newborns: A Painful Problem”

Dear Steve,

Your “Ends and Means” essays are always worth reading, and I appreciate being on your email list. I value the experience of being on the IEEE Society on Social Implications of Technology board with you for a time, and it has been a privilege to know one of the founding fathers of engineering ethics. It is with that same sense of collegiality and fair discussion which we shared in SSIT board meetings that I undertake to disagree with you regarding your latest essay, “Unwanted Newborns: A Painful Problem.”

I will first try to restate your argument as accurately as I can. Your analysis is basically an exercise in utilitarian ethics, and its underlying premise is that actions are to be judged according to whether they accrue to the greater happiness of people, and by the same token, whether they result in less unhappiness. Another premise is your definition of who counts as a person. In previous essays you have put forward the idea that murder is wrong mainly because it makes people afraid of being murdered, which is, among other things, a type of unhappiness. You draw upon this notion to examine the case of newborn babies who for various reasons (handicaps, disabilities, the unfitness or unwillingness of the mother) are not desired by their parents and are a potential burden on society. Because newborn babies give no evidence of fearing or even understanding death, you conclude that they cannot be subject to such fear. They are therefore exempt from the main reason you have previously put forward to justify society’s no-murder rule. You conclude that the government (or society) should defer to the persons most concerned—namely, the parents—in the case of unwanted newborns, and if the parents decide to kill the child (either actively by execution or passively by withholding treatment, medication, or food), your ethical reasoning tells you that such an act is not wrong, as difficult as it might be for all concerned.

Steve, if I agreed with your premises, I would have to agree with your conclusion because it follows logically from your premises. But your premises are mistaken. Here is how.

Your major misstep is to exclude newborn babies from the category of those with a right to life for the reason that they cannot (apparently) conceive of or fear death. This is in contrast to the approach favored by many right-to-life groups and individuals (including myself), which is to confer the right to life upon any biological entity that can be shown to be a human being at any stage of development or consequent stage of life. The latter criterion includes everyone from a just-fertilized human ovum all the way to a 100-year-old man in a persistent vegetative state.

There are important differences between these two criteria.

Your criterion is based on a behavior, or rather, the lack of a specific insight on the part of the baby which we deduce from the baby’s behavior: namely, the knowledge and fear of death. My criterion is based on physical evidence that can be easily and scientifically verified, e. g. by a DNA test to show whether the being in question is a member of the species Homo sapiens. This criterion essentially says, “If it is alive, and if it is human, then it qualifies as a person.” I think you will admit that applying my criterion is a fairly simple and straightforward matter that in most cases can be done by inspection.

But what about your criterion? Exactly when does a baby reach the age at which it can understand and fear death? Moreover, does this fear have to be active, or merely a potential fear? And how do you know whether it is present or not in any given individual? Must we develop an “awareness-of-death inventory” and administer it before legitimately taking a newborn child’s life? We are talking about an extremely serious matter here—the qualifications for membership in the rights-endowed human race—and it will not do to make unverified assumptions or generalizations. I hope you will not accuse me of undue levity if I say that I have known some teenagers who, at least by their behavior, showed no evidence whatever of the fear of death. Should they therefore be disqualified from membership in the category of humans, allowing us to kill them at will? Handicapped infants are not the only beings who can become a burden to their parents.

I find it ironic that you, who make no secret of your Jewish heritage, nevertheless contrast your position with that of the Nazi regime, which engaged in the killing of innocent human beings on a mass-production scale. I disagree when you say that adopting your idea to exclude newborns from the right to life will not lead to a slippery slope downward toward another Holocaust. Both you and the Nazi regime have already taken the first step: namely, the act of dehumanizing someone who most people would normally regard as a person.

If you study the memoirs of former concentration-camp guards, you will find that their need to view the prisoners as cattle, vermin, raw material for soap—anything other than a fellow human being—was critical to the guards’ ability to continue the heinous work in which they were engaged. Once they admitted to themselves that the naked, trembling body before them embodied a soul just like theirs, the game was over, and there was nothing left to them but suicide, desertion, or insanity.

Once you make membership in the human race dependent on any manifested ability and not on objective physical facts, you have crossed a critical line, and the rest is merely details. Whether you specify the ability to fear death, or to say “Heil Hitler” or “Hail, Caesar,” or integrate sin(x) dx, or anything else, you have fundamentally changed the category of qualification from that of physical nature to that of performance or behavior. To qualify as human, one must not simply be human, one must do something that is regarded as characteristic of humans. Exactly what activity is used as a criterion is secondary.

Even if you and I were to agree that a performance-based qualification for human rights should be adopted, the one you choose is problematic in the extreme. You cannot prove that babies do not fear death in the same way that I can prove by a DNA test that a baby is human. The idea that babies do not fear death is a speculative conclusion based on the lack of evidence to the contrary. And as most scientists would agree, absence of evidence is not evidence of absence. While newborn babies cannot talk and therefore cannot communicate the essence of their experiences to us, no one except newborns has any idea of what it is like to be a newborn, any more than I have an idea of exactly what it is like to be a wombat or a gerbil. Who knows but what any unpleasant experience, from hunger to the sight of an unfamiliar face, is more terrifying to an infant than facing a firing squad is for an adult? Certainly some babies scream as though it is.

Your failure to follow out some of the implications of your logic leads you to make some unguarded statements that, on examination, turn out to be little more than hopeful wishes rather than reasonable bases upon which to erect a system of ethics. For example, in discussing your principle that murder is to be avoided because it causes the fear of death in others, you write, “Nobody should have valid cause to worry that they might at some time in the immediate, or even remote, future be deprived of their lives.” You probably had in mind an unwritten supporting clause, namely, “deprived, that is, by the intentional actions of others.” But Steve, every one of us has valid cause to worry that we might at some time in the future be deprived of our lives. So far, the death rate among humans is 100%. The art of living consists largely in resisting the despair that continued contemplation of our deaths will induce. And there are two main ways to fight this despair.

One way is to philosophize. And philosophizing is anything but an exact science. One reason that different philosophers reach such a variety of conclusions about any given moral issue is that they begin with different assumptions. And while many given philosophical systems can be made internally consistent, each must begin from assumptions that can only be granted or denied, not argued about logically unless the participants share a deeper basis of assumptions on which their argument is based.

There are many moral philosophies that deny it is permissible to kill newborns. The fact that your particular line of reasoning concludes the opposite simply expresses the fact that you have chosen a different set of assumptions than other moral philosophers have. But having chosen those assumptions, you can go on about the business of life knowing that you have at least made an effort to be logically consistent. And until death puts an end to all philosophizing, your philosophy can provide you with a guide to moral action.

The other way humanity has found to combat the despair of the contemplation of death is through religion. You mention religion, or rather “religions” toward the end of your essay, but after admitting that most world religions do not condone “neonaticide,” you say that because we in the U. S. live in a pluralistic society, religious scruples about killing newborns should not be imposed on those who do not subscribe to them. So your ultimate response to religious arguments against killing newborns is to claim political immunity from such proscriptions.

How did it come about that you live in a society which respects your right to dissent from the beliefs of a religious majority? The founders of the United States wisely saw that a coerced religion is really no religion at all. They valued religion too much to make it compulsory. They left citizens responsible only to God, or their own consciences, with regard to religious belief, and prohibited the governmental establishment of religion, as well as any law preventing the free exercise thereof. Why they did so is a matter of some historical complexity, but an important contributing factor was the then relatively new idea in Protestant Christianity that faith in God was a matter for individual inquiry and decision, rather than a government-imposed requirement.

By contrast, history shows that governments based on an explicitly atheistic philosophy have no compunction about defining humanity in almost arbitrary ways, and in terminating those whose right to life has been revoked by their failure to meet certain requirements for behavior, or descent, or income level, or almost anything else you care to name. In adopting a policy such as the one you urge, the U. S. government would be endorsing the idea that personhood depends on an aspect of intellectual capacity, not on the simple fact of being human. Of course, the Roe v. Wade decision arbitrarily deprived millions of unborn children of the right to life, but the fact that opposition to that decision and its consequences is as strong now as it was thirty years ago shows that many U. S. citizens disagree with the arbitrary removal of the right to life simply because the life in question is inconvenient or painful for others.

Steve, I value my memories of the many times that you spoke your mind regardless of the consequences, and made a positive difference in the way engineering ethics is discussed, debated, and practiced. It saddens me to see you apply your great abilities to a moral problem and come out on the wrong side. While I do not have much hope that my words will persuade you to change your position, I would like to think that my respectful opposition to it is in the same honorable tradition that you yourself have established.

Yours sincerely,

Karl Stephan

Wendell Berry and the Two Economies

Modern engineering as it is currently practiced is deeply embedded in the context of the global economy of modern industrial societies. Large corporations are the only organizations complex enough to coordinate the production of things as intricate as computers or airliners. So when someone such as writer and philosopher Wendell Berry criticizes the economic basis on which current engineering depends, his words are worth considering for their indirect implication that engineering, too, in some respects, is a house built on sand.

In an essay entitled “Two Economies,” Berry first recognizes the thing we usually mean when we say “economy”: a global system of exchange based on what is called fiat money—money that is a creature of governments which, as the U. S. Federal Reserve recently announced plans to do, can create as much as $600 billion out of thin air over a period of a few months. And that is one of Berry’s complaints about that economy: the fact that it is not based on anything beyond the say-so of certain powerful people and interests who attempt to control it to their advantage.

But beyond the thing that is usually meant by “the economy” lies an all-encompassing principle or entity that Berry chooses to call the Great Economy. It is, he says, “. . . the ultimate condition of our experience and of the practical questions rising from our experience” and is “both known and unknown, visible and invisible, comprehensible and mysterious.” The idea of the Great Economy makes no sense outside of religious considerations, but that need not detain us, since every great classical religion says something meaningful about the Great Economy, though not in those terms.

In contrast to the human-created economy which is to some extent manageable, the Great Economy cannot be managed. It can only be conformed to by individuals and groups who acknowledge their inability to be fundamentally in control of their existence. Only when we admit that can we go about the business of constructing a human economy that works according to the terms of the Great Economy.

How would the world’s economy change if it conformed more to the Great Economy? I can mention only a couple of Berry’s ideas in the limited space available here. One is to cease viewing the various goods of the Great Economy as resources to be exploited. Berry says of the modern industrial economy that the “invariable mode of its relation both to nature and to human culture is that of mining: withdrawal from a limited fund until that fund is exhausted.” According to Berry, the industrial economy acknowledges no limits and recognizes no ultimate goals: it “cannot prescribe the terms of its own success.”

Berry sees much that is fundamentally wrong with things that most of us take for granted and rarely think about. He is not surprised that proponents of free enterprise end up so often on the dockets of criminal courts, and that much of modern medicine has become an “exploitive industry, profitable in direct proportion to its hurry and its mechanical indifference.” The reason is that as long as one never looks beyond the limits of a human-created economy, one ignores the Great Economy at his peril. But such ignorance comes at a price, and billions of people around the world pay that price every day.

Berry is probably the leading living proponent of the philosophical and economic movement called agrarianism. More than just a simplistic back-to-the-farm philosophy, agrarianism sees humanity in a holistic way that views work, leisure, money, community, and government as integrated parts of the Great Economy. One of the first arguments most engineers might think of when confronting the ideas of agrarianism is that if everybody tried to live out its principles, our present way of life would be destroyed. Not everybody can live as a subsistence farmer, or even has the interest, ability, or resources for such a life.

But that argument is itself taken from the industrial-economy playbook, which instantly takes any proposal and tries to homogenize it, duplicate it, and apply it worldwide. Those very actions are counter to agrarian principles, which are primarily local, personal, and can take form only in the context of small communities where people know each other. And in fact, as Berry points out, there are thousands of Amish farmers and other members of certain religious communities (including monasteries) where a good bit of the agrarian ideal works in practice.

So what should an engineer take away from Berry’s picture of the Great Economy that surrounds our human economies like a family home encompasses children in a back-yard treehouse? Well, short of dropping out and joining an Amish community, religion and all, I think engineers could benefit in several ways from thinking about Berry’s ideas. No plans turn out quite the way we expect, for one thing. That sounds like a restatement of Murphy’s Law (“if anything can go wrong, it will”), but in fact it is an admission that the imponderable and unpredictable, especially if human beings are involved, can easily overwhelm the calculable and certain. And thinking about the people who ultimately use the things engineers work on, and the cultural and spiritual contexts of their lives, is something we could all do more of, to the benefit of both society and our own organizations.

Many of the dire predictions Berry has made over the years have either come to pass to some degree, or are so much a chronic condition of our times that we have ceased to notice them. But we can sometimes learn more from our critics than from our friends, and I would urge anyone who has never read anything by Wendell Berry to do so soon.

Engineering Ethics and Natural Law

As anybody who has read this blog for a while knows, I do not view engineering ethics as a narrow, specialized field where only experts can render the right opinions. I believe anyone who has enough moral sense to graduate with an engineering degree has the ability to think ethically, and with a little help and advice can make good ethical judgments about a wide variety of professional concerns. Today I will explain why I think this is true.


If a person can think clearly enough to do engineering, he or she has what I will term a “deep knowledge” of right and wrong. This knowledge is not the same as what we conventionally call “conscience”: it is more like the fundamental principles on which everyone’s conscience is based. Some examples of this deep knowledge are things like:


Being fair is better than being unfair.


Betraying a friend is wrong.


Marital infidelity is wrong.


Evidence for this deep knowledge is to be found on every children’s playground and in the legends, literature, and law of every culture. It is simply an empirical fact that normal human beings have an inborn knowledge of right and wrong at a deep level.


This is not to say that everyone in every culture agrees on every detail of every ethical question. This deep knowledge combines with cultural norms, life experiences, training, and other factors to produce a conscience of which we are consciously aware. Some people manage to suppress their deep knowledge so that even their conscience does not bother them as they go about committing serial murders or turn themselves into suicide bombers. But rest assured the knowledge is there; it has simply been suppressed by other influences. The idea that this deep knowledge of right and wrong exists at some level in every human being is called “natural law.”


A person who has mastered the technical material of an engineering discipline has the intellectual capacity to understand and imagine the ethical consequences of engineering activity. Whether or not they apply their minds to this question is a matter of training and discipline. Up to the twentieth century, most people (including a good many who benefited from college educations) belonged to a religious tradition which encouraged acceptance of the principles of natural law, and legal codes were largely in conformance both with religious tradition and natural law as well. But with the advent of various totalitarian governments and a broad rejection of religion as a serious matter in higher education and elite classes, things changed.


Today you will find little support for the idea that everyone has a deep built-in knowledge of right and wrong which simply needs to be elucidated to become effective. Colleges and universities either avoid the subject altogether or teach ethics in a way that would never work for mathematics or physics. Imagine in your first physics class if the instructor got up and said something like, “There are many physics traditions: some people believe F = ma, while others believe F = m + a and still others believe F = m/a. We will not insist on any one of these, and simply want to tolerate everyone’s opinions on the subject while thinking how to apply these principles to practical situations.” It sounds absurd, and yet many instructors of professional ethics take what amounts to that position with regard to ethical principles. And if you go to experts who base their ethics on elaborately wrought philosophical structures, you can find someone who will justify anything from drug testing using people hired off the streets, to infanticide (the famous Princeton philosopher Peter Singer has said that killing newborns is not the same thing as killing a person).


As natural-law philosopher J. Budziszewski has said, our deep knowledge of right and wrong is still there, but factors such as the atrophy of tradition, the cult of the expert, and the disabling of shock and shame have made it harder for us to connect with that deep knowledge and act on it. Thus it can be that trying to do ethics in accordance with certain complex philosophical approaches can take you to a conclusion that makes logical sense, given your philosophical assumptions, and yet feels wrong. I am here to say that in such a case, you probably ought to go with your feelings.


But not always: “going with your feelings” is one more factor that has landed us in more trouble with regard to natural law. A moment’s thought will reveal how wrong it is to say that one’s feelings must always be followed as a guide to action. Yet for people who have no belief in the deep knowledge of right and wrong, and base their moral decisions on examples from popular culture where following your feelings is a bedrock principle, there may be nothing better to turn to. Feelings are real, and paying attention to your feelings is important, but unless you are some kind of saint, obeying your feelings is not going to lead to the right decision all the time (and even the saints admitted to having wrong feelings from time to time).

If I had room, I could explore the reasons for believing in this deep knowledge, which ultimately lead back to the idea of a Creator who designed them into us in conformance with the way the world is. But the nice thing about natural law is that even if a person doesn’t believe in God, the deep knowledge is there, and if you can help bring it to the surface, their conscience will guide them to the right decision regardless.


This is why I believe engineering ethics is not just a field for experts. Everyone can do it, but it requires thought as well as feelings, will as well as intelligence, and reliance on something that is ultimately not of our own making.


Sources: I relied on J. Budziszewski’s book What We Can’t Not Know: A Guide (Spence, 2003) for the basic ideas in this blog. It is highly recommended as a readable yet sophisticated and thorough treatment of applied natural law. I last mentioned natural law in my blog of Nov. 23, 2009 (“Ethics: Evolved or Given?”).

One Spammer Down, Thousands to Go

The people who invented what we now know as the Internet almost certainly did not intend for it to be used mostly for sending unwanted messages that cost the recipient a lot more than the sender, seldom get read, and serve almost no redeeming social purpose. But according to the Wikipedia article on e-mail spam, 78% of all e-mail messages sent over the Internet are the mass-produced, often illegal type of advertising known as spam. Last month, this incredible flood of junk slowed down by about a fifth after Russian authorities took actions against Igor A. Gusev, the head of Spamit.com. Gusev, who fled the country after his house was raided Sept. 27, ran Spamit.com as a kind of spam wholesaler, paying “retail” spammers to send junk e-mails. Once his website closed, many senders of spam saw no point in carrying on and shut down, at least temporarily. Experts cite this as the main cause of about a 20% decrease in the volume of spam worldwide. However, they expect that other entrepreneurs in this sordid activity will soon show up to take up the slack left by Gusev’s departure.


The Internet has taken its place alongside power grids, water-supply systems, and snail mail as one of the modern-day utilities we all rely on. But I was amazed to learn that nearly four-fifths of all e-mails sent are spam. If I consider what fraction of snail mail delivered to my door is in the same category, however, it’s not so surprising.


Every form of unsolicited advertising entails some effort, however minor, on the part of the intended recipient. Even ignoring billboards on the freeway takes a bit of mental effort, although it’s so miniscule as to be negligible. Throwing away physical pieces of paper that come in the postal mail is a more substantial time-and-effort sink, although one’s expenditure is limited to the reading needed to save the desirable or necessary things such as bills and toss the rest. But the main cost of snail-mail advertising is borne by the sender.


Not so for spam. As the Wikipedia article on e-mail spam points out, spam is equivalent to postage-due advertising, since the per-message cost to the spammer is an insignificant fraction of what it costs the recipient to deal with spam, either through blocking filters or the old-fashioned way of selecting and deleting it. Either way, the estimated cost to the recipient per spam message is about ten cents, which multiplied by the many billions of spams per year means that U. S. businesses alone spend on the order of $20 billion a year that they would not have to spend if spam weren’t such a problem. And this doesn’t even begin to address the other issues connected with spam, such as the illegal “botnets” set up by spammers to send most of the stuff, the phishing attacks that many spam messages contain, and the viruses and other malware that spam can infest your computer with.


So why has this pernicious situation been allowed to develop? One big problem is the prevailing U. S. law governing spam, the CAN-SPAM Act of 2003. This law sets certain standards for spam in order for it to be legal, such as truth in the subject line and no forged addresses. As long as spam meets these fairly low standards, it is not illegal, at least according to Federal law, which pre-empted most state laws about spam. CAN-SPAM is a lot more lenient than many European laws against spam, and since the U. S. is the place where much spam originates (or at least is sent from by botnets, which are themselves illegal), our relatively lax laws exacerbate the problem for the rest of the world. Since spammers easily can live in one country, conduct their business transactions in a second country, and do their technical operations in several other places around the world, combating the problem in an organized way requires international cooperation. And unless things get really serious, such as the prospect of some kind of organized attack on a nation’s Internet infrastructure, ordinary spam is not something that attracts the attention of the limited resources of international law enforcement organizations.


All the same, it is too bad that the present Internet structure makes it so easy for spammers to get away with their nefarious activities. Engineers like efficiency, and to see nearly 4/5 of a resource go to something that is usually illegal, almost never succeeds in the sense of generating responses, and does nothing but annoy most recipients and cost them money to get rid of, is just a shame. It may be too late to do much about it, such as redesigning the Internet to make unsolicited emails harder to send. There are occasional discussions about redoing the fundamental technical structure of the Internet, right down to the protocols, but this would be like switching the world’s electric utilities from AC to DC, a huge production that would not be easy to carry out. Short of that, I suppose we will all just have to regard spam as one of those necessary evils like noise in communications channels. Noise is due to fundamental physical laws, while spam derives ultimately from choices people make. The fact that some people will make wrong or evil choices seems to be as reliable as the law of gravity, though. It was G. K. Chesterton who said thatz the Christian doctrine of original sin—the idea that everyone is born with the ability to sin—is the only one for which there is abundant empirical evidence. And spam seems to bear that out.

Wave Shield: Prize, Placebo, or Fraud?

The other day, my wife brought home from the health-food store a brochure advertising something called a “Wave Shield.” The headline on it reads, “Finally, cellular protection.” They’re not talking about body cells, but cell phones and cordless phones. Even before wireless consumer products hit the market, scientists were studying the question of whether the low-level radio-frequency electromagnetic emissions from cell phones and similar wireless devices could cause bodily harm. While this is no place to review the vast literature on the subject, I have read summaries and am qualified to express an opinion, because electromagnetics is my professional specialty. The best I can tell from the decades of research is that, if there is any deleterious effect of cell-phone use in terms of causing brain cancer or other serious health problems, it is a very small effect and probably insignificant compared to most other elective hazards of daily life, such as using cell phones while driving.


However, there have been enough scary news reports over the years to raise at least a suspicion in the public mind that something bad may result from using cell phones and other wireless gizmos. The Wave Shield company of Boca Raton, Florida has decided to cash in on that suspicion. Here is how.


Their advertisements are carefully designed to stay within the letter of the scientific facts. Every statement of possible damage due to wireless-device use is couched in terms of “may” or “could,” not “will.” But their pictures of three-year-olds using cell phones and MRI cross-sections of before-and-after rat brains subjected to RF (the intensity is not stated, but it was probably far in excess of anything a cell phone would radiate) are all designed to inspire fear in the reader.


Once that happens, here comes the solution: a little metal ring with a tiny piece of window-screen-like metal mesh in it. The idea is, you fit this thing around the earpiece of your phone, and it reduces the radiation in the immediate vicinity of the screen, say, half an inch away or so. It does essentially nothing to keep most of the radiation from the phone away from your brain. To their credit, the Wave Shield people admit as much: “The vast majority of electromagnetic radiation emitted by cellular and cordless phones comes from the antenna and parts of the phone other than the ear piece. Wave shield products have no effect on this electromagnetic energy.” But they are counting on the public’s “innumeracy” (inability to make quantitative judgments other than comparing prices), fearfulness, and ignorance of electromagnetic theory to yield them a customer base willing to pay twenty or thirty bucks for a little ring with a screen in it.


The company’s website has testimonials, which I have no reason to believe are not genuine. But here we encounter the placebo effect: the fact that taking even sugar pills that cannot possibly have any objective chemical action on a given malady will nevertheless make a certain percentage of ill people feel better. Nobody in the testimonials says they have been cured of brain cancer, but they cite reduction of headaches and a perception that the phone is cooler as benefits of the Wave Shield. The “cooling” probably results from the space opened up between the head and the phone by the thickness of the ring. You could get the same effect from a piece of cardboard taped to the phone, but it wouldn’t look as good. And the perceived reduction in headaches could be a classic case of the placebo effect in operation.


This campaign is a specific example of a common phenomenon in the advertising of technical products which, if not strictly unethical, certainly takes an arguably unfair advantage of potential customers. It is what I call the “appeal to the lizard brain.” Apparently, psychologists working with advertisers have found that while most people are capable of following logical arguments and making buying decisions based on conscious rational thought, we all have a more primitive part of the brain which we share with lower animals such as lizards. This lizard brain knows nothing of logic, and instead operates on emotionally-based criteria such as fear and a striving for the satisfaction of physical appetites for comfort, food, and sex. The popularity of large SUVs, for example, derives largely from the fact that the lizard brain thinks driving around in a big intimidating car will keep you safer than driving a small, pipsqueak car. This is despite the fact that the better maneuverability of small cars makes them safer, in many cases.


Another way advertisers appeal to the lizard brain is by saying the cautious legal things in words, but showing emotionally charged pictures that contradict the words. Wave Shield shows they have learned this lesson with their photos of innocent children using cell phones and ghastly deteriorated brains designed to make you ask, “Is that happening to my brain?” Makers of drugs that lower cholesterol do the same thing. If you watch an ad for one of those drugs, while you hear the announcer reading the long list of side effects and saying the drug should be supplemented by changes in diet and exercise, the screen shows photos of luscious, fat-heavy pot roasts and bowls of ice cream—all things you are NOT supposed to eat if you’re lowering your cholesterol. The message, of course, is that if you take our drug, you can eat anything you like and not worry about your cholesterol.


Engineers engaged in such enterprises may take the attitude that “hey, all they pay me to do is to make sure the product meets the technical specifications. What marketing does with it is not my problem.” Well, if advertising strays over the line into fraud, it can be your problem. And even if the advertising is technically within the letter of the law—as with Wave Shield’s disclaimer that their product basically doesn’t do squat, but couched in language that most consumers won’t understand or pay attention to—if the overall effect is to sell somebody a thing that doesn’t really do what the lizard brain thinks it will, the spirit of the laws against fraud has been violated.


All the same, there is nothing new about this sort of thing. The best guard against it is an educated public and a profession of engineers who will not tolerate misleading advertising of products they contribute to.

Happy Ending for Chilean Mine Rescue, But What Next?

Anyone who watched last Wednesday as the thirty-three trapped Chilean miners were hauled up one by one through a two-thousand-foot borehole must have felt at least some emotion as we witnessed the great joy and relief the miners and their relatives and friends expressed. This was truly the best possible ending to a type of disaster that so often ends with funerals instead of parties. Many kudos go to the Chilean, Canadian, and American engineers and managers who drilled access and transportation boreholes accurately, safely, and in record time to make the rescue possible. But the highest congratulations go to the miners themselves, who, despite rumors of arguments deep underground, managed to survive those first seventeen days on two days’ worth of rations and hope that help was on its way. The truth of their survival is probably better than the fictionalized movie and book versions that no doubt will be forthcoming. But as an Associated Press article published yesterday examines the futures of these miners, this would be a good time to look at the ethics and economics of mine operations in general.

As the AP article points out, by U. S. standards all the miners are very poor, and since the company that owned the collapsed mine has now declared bankruptcy, all its three-hundred-some-odd miners are now out of work. One miner returned to a “wood-and-tin” house where sixteen people live, and the street where he lives was lined with plastic bags filled with air because the residents could not afford balloons. Working in a mine—at least as long as you don’t own it—is no way to get rich, except perhaps by comparison to what you were doing before. If you were a subsistence farmer whose livelihood depended on the vagaries of wind and rain, you might view a mining job as a great way to improve your life. It lets you live in a city or town rather than the country, it gives you a regular job that doesn’t depend on the weather, and as long as your health and strength hold up, you can even earn enough to provide for a family.

With the exception of freelance prospecting, mining is a capital-intensive business, which means the people who put in the money to make the mine work are the ones who reap the profits. The miners themselves are paid wages and perhaps some benefits, and take the risks normally associated with mining. There is apparently no such thing as an absolutely safe mine, unless no one ever goes in it, and the day of totally robotic mining has not yet arrived. So for the foreseeable future, there will be mine owning and operating companies that hire local people to do the dirty, dangerous work underground.

There will also be a tension between spending money on safety equipment, training, and other overhead expenses that improve the miner’s lot, and spending it on means of exploiting the mine itself. This is why governments enact mine safety regulations and enforce them, because human nature is such that if firms are left strictly to themselves, the dangerous cost-cutting mines make more money and drive out the safer ones, other things being equal (which they never are, of course). The ultimate unrestricted free-market situation for mining in South America existed during the early years of Spanish exploration in the 1500s, where natives were basically enslaved to work the mines. Things are much better now, but the temptation to create a kind of de facto slavery with company towns and stores is always present, and has to be guarded against.

In the best possible circumstances, mine operators treat their employees fairly and run their mines under a consistent and justly administered set of rules that make the playing field as even as possible in a given country. Commodity prices, which ultimately determine whether a given mine is profitable, are currently beyond the control of any one country, but whenever a mine’s output is worth mining, all parties involved can work together to achieve a stable balance between safety and efficient production.

Another lesson from the Copiapo mine saga is that engineering can do only so much. The character and behavior of the miners themselves was critical in this rescue. If thirty-three college professors had been trapped underground instead of thirty-three miners, I fear the only thing the drill would have found after seventeen days would be the minutes of a long and increasingly contentious faculty meeting that concluded in mass slaughter. Despite the hopes and speculations of groups such as the transhumanists and others who think man will eventually conquer nature completely, technology can do only so much. The humanity and faith of the miners and their people aboveground made as much or more difference to the outcome as the best technology could offer. Of all the lessons we can learn from Copiapo, I think that may be the most important one.

Red Tide of Disaster in Hungary

The town of Kolontar in western Hungary is about halfway between Budapest and the Austrian border. Like many other former Iron Curtain countries, Hungary has its share of old heavy-industry installations, and an alumina processing plant stands next to Kolontar. The facility no doubt provides some welcome employment, but the preferred method of making alumina is a nasty business. You start with bauxite, which is a mixture of pure alumina (aluminum oxide, from which the metal is made) and other minerals. These other minerals do not dissolve when you treat the ground-up bauxite with sodium hydroxide, otherwise known as lye. The alumina stays in solution as it converts to aluminum hydroxide, you filter out the undissolved material, and then heat up the hydroxide to turn it back into pure alumina, now minus the other minerals.

So far, so good. But what do you do with the leftovers, especially when we’re talking about tons of material a day? The byproduct of this process is called “red mud,” and there’s not much use for it. It still has the pH (a measure of acidity or basicity) of lye, and if there were any heavy metals such as arsenic or mercury in the original bauxite, they are still in the red mud. The Hungarian Aluminum Production and Trade Company, which owns the plant, chose to build large open retaining reservoirs and simply ran the mud out to the reservoirs. As long as the reservoirs held together, this at least localized the problem. But last Monday, Oct. 4, one of the retaining walls (perhaps weakened by heavy summer rains) collapsed. According to an MSNBC report, the resulting red tide flooded most of Kolontar and parts of other nearby towns, killed at least seven people, and sent 150 or so to hospitals for treatment of alkali burns and other injuries.

The investigation into the cause of the collapse is just beginning, but the issue I’d like to address is the practice of what you might call deferred environmental protection. Thousands of various industrial processes make byproducts which, like red mud, take up a lot of space but have no economic value. In fact, to the extent that getting rid of them costs money, they have negative economic value. To treat red mud so that it could be used as fill at construction sites or even in garden soil would cost a lot, first to neutralize the alkali content with acid and then to filter or extract the hazardous heavy metals. If the firm that runs the Kolontar facility spent all this money to make red mud at least disposable without danger, their alumina would cost more than the average commodity price, and the firm would likely go out of business—at least out of the alumina business.

I’m no chemical engineer, and I don’t know what the standard practices are for alumina production. But I suspect that in today’s global economy, the other alumina producers are doing pretty much the same thing as the Kolontar factory did. The only reason we haven’t heard about them is that their reservoirs haven’t sprung leaks—yet.

To what extent should we tolerate the warehousing of hazardous materials in localities where they do no immediate harm, as long as proper precautions are taken? At any given time around the world, there are thousands of tons of highly poisonous materials in chemical plants, factories, and city warehouses, and an accidental release of just one of these materials could kill thousands, as it did in the 1984 Bhopal, India toxic-gas disaster. But because our modern industrial society demands good things that require dealing with these nasty chemicals, we put up with the danger of having them around. And it is largely the responsibility of engineers to see that hazardous materials stay under control, even if they have no useful economic purpose.

Sometimes indefinite storage of hazardous waste just has to be built in to a business plan. Because there is not yet a national storage facility for radioactive waste, most U. S. nuclear power plants have to store their spent fuel on site. The cost of doing this projected into the indefinite future is factored into the cost of doing business. Fortunately, the volume of nuclear waste is much smaller than the waste products of a coal-fired power plant, for example, so the storage problem has proved to be manageable so far.

But alumina production is a different affair. In 2009 the stuff was selling for only about $300 a ton, so dealing with a highly competitive world commodity market means that alumina producers simply can’t afford a lot of fancy pollution-remediation facilities that their competitors aren’t using. In countries such as the U. S. where environmental laws are fairly strict, you don’t see a lot of alumina factories, partly because compliance with the laws here would quite possibly price their product out of the market altogether. If you take a strictly nationalistic viewpoint, you could say that if a country such as Hungary chooses to let its industries produce cheap, profitable commodities at the expense of polluting large tracts of land and putting whole villages at risk, then it’s their right. But I doubt that a well-functioning democracy would knowingly allow the kind of dangerous behavior that resulted in last week’s red-mud disaster.

At the very least, inspections and repairs to the reservoirs should have been better. Future generations would still have to deal with the question of how to dispose of the red mud, but at least the problem would have been under control. Once the investigation is complete, we can make a better-informed judgment about what happened in Kolontar and how similar tragedies can be avoided in the future. But the answers may not be easy to come by.

Innovative Help for Haiti

When the worst earthquake in many decades struck Haiti last Jan. 12, it killed over 200,000 people and wrecked hundreds of thousands of buildings. In the months after the quake, Haiti gradually faded from the news, but for Haitians, the quake continues to be a life-changing event that they will never forget. I’d like to look at some rare good news that has come about in relation to the devastating tragedy of that earthquake.

The sheer size of the housing and construction problem in Haiti has created an opportunity for innovative architectural designs that address the specific complex of needs that Haitian reconstruction embodies. These needs include low cost, earthquake resistance, and simplicity of construction. I recently received an email from a Canadian firm called CBD Building Systems. “CBD” stands for “curved by design.” Their basic notion is simple: use short pieces of lumber (they can even start from mill tailings, pieces that are normally thrown away) to make curved sections of a dome-like building shaped like a large igloo. The vertical members are just straight pieces of wood, while the curvature is established by the horizontal members. (See their website referenced in the “Sources” section for pictures.)

Normally I don’t pay attention to companies that just ask me to mention them on my site, and all I have to go on for this one is what their website says. But as the co-founder said in an email, they claim to be applying engineering ethics “beyond the influence of any building codes” and supplying earthquake-resistant structures at a cost they say is below that of some tent-type temporary housing.

If all this is true (and I have no evidence to the contrary), then I say good for CBD Building Systems. They saw a need in a place where the need exceeds the potential profit, and for reasons that are at least partly altruistic, they have made an extra effort to put their product in Haiti and adapt it to the particular circumstances that prevail in that woebegone country. I do not know if they have made a profit from their Haitian venture so far—it seems doubtful. But there is a long tradition, not so much honored today, of engineering firms that take some of their profits and put them into charitable engineering activities that don’t make money, but do somebody good.

I don’t recall the details, but years ago a profitable, privately held firm called General Radio based in Massachusetts sold a small line of aids for blind people, priced well below cost. CBD Building Systems seems to want to make money as well as benefit the people of Haiti, and other parts of the world where their products can be used. I see nothing wrong with that, especially if non-governmental organizations (NGOs) get involved in funding the effort.

Of course, one must be careful to study the details of the situation on the ground. History is full of stories of development projects that benefited everybody except the people they were designed to benefit. In a presentation by members of Engineers Without Borders, an organization that recruits student volunteers to do engineering projects in developing countries, I learned that up to half the effort expended on a typical project is devoted to researching the specific target clients and location, and tailoring educational and training efforts as well as the technical aspects of the project to ensure that a truly lasting benefit accrues to the people on the receiving end. I hope that the same kind of attention is paid by CBD Building Systems and other similar firms which are developing housing adapted to the Haitian situation.

Of course, engineering is always done in an economic context, and we can’t expect a few clever architectural ideas to solve the problem of poverty in Haiti, or anywhere else. If companies can’t make money with their products, they can’t keep making them, and so housing for impoverished devastated places like Haiti may always be just a sideline to most firms. What would really be innovative is if some of these companies set up manufacturing in Haiti itself, and provide much-needed employment for a country that is chronically near the top of the list of poor Western Hemisphere nations. That isn’t engineering, strictly speaking, but it would represent a different kind of extension of the idea that those of us blessed with the ability to do engineering owe something that we should give back to the world.

I thank Peter Black,CBD Building Systems co-founder, for bringing my attention to their work. While they are not the only firm working in the area of relief housing, their efforts are to be commended, and held up as an example of how engineering can be both profitable and beneficial to those in special need.

P. S. After posting this article, I received the following comment from Peter Black:

We use a dome wood technology to create a linear curved structure 65 ft long and 24 feet wide which houses 12 families and is earthquake and hurricane proof, fire and termite proof with shuttered screen windows, doors, solar powered lights and fans. We considered manufacturing there but the infrastructure is just not there so we designed so 85% of the product's labour will be done by low skilled Haitian workers who work for $6 - $12 per day thus injecting some much needed economic development and Haitian pride. The local workers take the flat-packed wood parts, assemble the frames and erect the structure which is designed to work as a ladder so you erect the shell bottom to top then add the exterior cladding from top to bottom. It takes 3-6 days to install the structure ready to move in. The cost ready to move in is Cdn$15/ sq ft where total living area is 5,376 sq ft or 448 sq ft per apartment. Temporary structures are costing as much as $19/sq ft there.

Is Birth Control a Sustainable Technology?

Last year, the IEEE Society on Social Implications of Technology (IEEE stands for Institute of Electrical and Electronics Engineers) devoted its annual conference to issues of sustainable development. One of the papers was presented by Jeff Robbins, who applied the second law of thermodynamics to the question of technology development. His point was that entropy always increases, and whenever you have a decrease in entropy caused by the production of ordered systems (as in technological development), there has to be a bigger increase in entropy elsewhere.

Robbins assumes that in order to survive, humanity must change its ways with regard to consumption of energy and technological activity. He says “. . . we are living unsustainably, our extravagant consuming feeding off coming generations.” He goes on to cite seven barriers that, as he puts it, stand in the way of “moving in the direction of where we know we have to go.” Leaving aside the question of whether a purely quantitative theory about mass and energy really applies to an issue fraught with social and ethical aspects, I would like to address what Robbins says about one of the “barriers” to sustainable development that he sees as a critical problem to be overcome.

Robbins titles this section of his paper, “Be Fruitful and Multiply.” He begins by saying, “When it comes to having children, few people think globally.” He shows how in religious groups such as the Amish or ultraorthodox Jews, where large families are both socially approved and encouraged, population growth is much higher than the average in their host nations. He then plays the Malthusian game of projecting what would happen if every couple had eight children instead of 2.07 or whatever the approved number is for zero population growth, and shows that one couple could produce 67 million offspring that way in only three centuries. And if that couple and their descendants happened to live in North America instead of the lower per-capita energy-use regions of sub-Saharan Africa, their energy consumption would eventually outstrip the planet’s ability to supply it.

In a way, I hate to pick on Robbins, because his fearmongering statistics belie a much larger global trend that he chooses to ignore. To his credit, some of his other barriers have stronger arguments to back them up, but I will reluctantly stick to his point about population growth.

The big news on the population front for the last couple of decades has not been overpopulation, but the coming population bust, which is already far advanced in countries such as Japan. With a birth rate of only 1.2 per woman, Japan is already experiencing the early consequences of a demographic collapse that may turn the country into either a “ghost nation” or a place that will be taken over by immigrants out of necessity. Either way, the dearth of babies has brought an unsustainable decline to the population which threatens Japan’s very existence as a nation.

The U. S. may be experiencing similar problems, though in a less acute way since this country has an exceptionally high birthrate compared to other developed nations. But it doesn’t take a Ph. D. in economics to figure out that if families are smaller, their need for housing declines, and eventually there are fewer families to buy houses in the next generation. There are many causes of the international housing-market collapse, but declining birth rates are certainly a contributing factor. And I’m saying nothing about the problems with social programs such as Social Security that depend on transferring wealth from the (presumably growing) younger population to retirees.

In fairness to Robbins, he may be aware of these trends, but in order to have something to say he picks on isolated groups where large families are the norm. If sustainable development means development that takes future generations into consideration, what about the very existence of those future generations? Before you can receive the benefits from the wise and sustainable decisions of previous generations, you have to exist. If the countries of the world contracept themselves out of existence and leave a clean, cool, pristine planet to the crickets, that may be very well for the crickets, but we have committed the most fundamental wrong possible against the future generations: we have denied them the privilege of existence. In all the discussions of sustainable development I have seen, the idea that birth control is anything but a beneficent technology with respect to sustainability never comes up. This is probably due to the deeply misanthropic philosophy espoused by the more extreme members of the sustainability contingent. They view people—other people, of course—as the problem, and therefore the idea of making fewer people in the future has to be part of the solution.

Robbins’ scary scenario of vast global overcrowding is almost certainly not going to happen. The United Nations itself (not exactly a hotbed of anti-sustainable-development activism) in its low range of population forecasts (which have historically turned out to be the most accurate) says that if the tendency of wealthier, more educated people to have fewer children continues, global population will peak at around 8 billion in 2040 and then begin a slow overall decline. So much for Malthus. In contrast to global warming, the end of oil, and other dire straits that Robbins cites as something to be feared in the future, the consequences of population collapse are already here and taking their toll on some countries.

As Steven Mosher points out in his Population Research Institute website, you can’t turn population collapse around easily. Once the number of childbearing-age women declines significantly, the demographics reaches almost a point of no return and even if the few women left have much larger families than previously, it’s basically too late to fix things. Of course, neither the Malthusian exponential growth nor the population-collapse exponential decline ever happen exactly in accordance with the math—societies are simply too complicated, and immigration, political changes, and other factors always intervene. But to the extent that the demographics proceed without major interruptions, it is a near certainty that population collapse will occur in a given group with something like the predicted intensity. Much of Western Europe is in the same sinking boat, by the way.

So the next time anybody lists a bunch of technologies that threaten future generations, I want to see birth control in the list. If it’s not included, then we are missing one of the most obvious ignored facts about sustainable development.

Mixing Academia and Military Secrets: The Case of J. Reece Roth

The plasma physicist J. Reece Roth wrote a book on industrial plasma engineering that I have found very useful in my recent research. So when I was asked to recommend a reviewer for a paper on plasma physics, I went on the Internet to find Roth’s email address. To my amazement, the first thing that came up was a story about how Roth had been indicted, tried, and convicted for violating export-law restrictions on technical data he had developed as part of an Air Force research contract. In July of 2009, Roth was sentenced to four years in prison for giving restricted information to Chinese and Iranian nationals and taking a laptop to China with restricted information on it. At this time, the 73-year-old Roth may not actually be in jail yet pending an appeal, but this sad end to a notable career is a cautionary tale for anyone who conducts research in an academic setting with certain types of military funding.

After graduating from MIT in 1959, Roth obtained a Ph. D. from Cornell and joined NASA, where he worked in plasma-fusion technology until 1978. He then joined the University of Tennessee at Knoxville and developed an atmospheric-pressure plasma technology which he published and patented. Around 2000, he co-founded a company called Atmospheric Glow Technologies (AGT) to develop inventions based on his discovery, and for a few years the firm did quite well, licensing several products which were made by other firms.

Along the way, Dr. Roth had made several trips to China in order to present his research work, and was named an honorary professor at two universities there. Like many other researchers in technical fields, he hired Chinese graduate students from time to time and communicated with them regarding the technical details of the research they were doing. So far, none of these activities would be of legal concern. But all that changed when AGT won a Phase I Small Business Innovative Research (SBIR) contract with the U. S. Air Force to do research on plasma actuators for drone aircraft.

There is nothing wrong about professors inventing useful things, or patenting their inventions through their institution’s intellectual property office, or founding companies to exploit the patents. This type of activity is becoming almost routine in academic science and technology, and is vigorously encouraged by many universities. Most people (not all) even think there is nothing wrong with professors who do military research. But if they do, they have to follow the rules.

Certain types of military research contracts have export-restriction clauses in them, meaning that any technical data developed as a result of the contract is subject to export-law restrictions. This is only reasonable behavior on the part of the military, which hopes to gain a technical advantage over their international competition. If the usual free and open access to information that is customary in universities were allowed for focused and applied military research results, the Air Force would be spending its money for the benefit of all military forces in the world, which is not the point. So the SBIR contract that Roth’s company obtained with the Air Force explicitly restricted technical results in this way and made them subject to the Arms Control Export Act (ACEA), which requires obtaining a license before disclosing the information to foreign nationals or exporting it to foreign countries.

Unfortunately for Roth, he thought he knew better than the University of Tennessee’s export coordinator Robin Witherspoon. Instead of founding his company at a physically separate location from his university lab and staffing it with company-hired staff, which would have made it easier to obey the export-restriction laws, he continued to use his university lab and his graduate students for both university and AGT research activities, paying for the AGT work through a subcontract with the university. This is a touchy way of doing things ethically under the best of conditions, and when you add export restrictions to the mix, you get a potentially explosive situation.

In May of 2006, when export coordinator Witherspoon discovered that in blatant contradiction to the terms of the SBIR contract, Roth had hired non-U. S. nationals to work on the project, she told him he had to remove them at once and find U. S. students instead. She also told him not to take any restricted information on a trip he was about to make to China.

Roth apparently believed that until he demonstrated a working prototype, his work was still “fundamental research” and not subject to export restriction laws. Acting on this erroneous supposition, he continued to communicate research results to his Chinese and Iranian graduate students and took to China a laptop containing proposals and research reports on the SBIR project. The University of Tennessee, fearing it would be charged with violations if something wasn’t done fast, informed the FBI and the State Department of Roth’s actions. When he returned from China, he found federal officials waiting for him. They confiscated his laptop and began an investigation that culminated in a federal indictment, a trial, and conviction on thirteen counts of violating the Arms Control Export Act.

Along with his many academic honors, Roth now has the dubious distinction of being the first professor convicted under the ACEA laws. His sad story should be a warning to anyone who wants to pursue the combination of activities that Roth did. Setting up a separate lab with U. S.-only workers would have made more work for Roth and perhaps less profit. But it would have kept him out of trouble with the law.

BP’s Report: No Smoking Gun, But a Lot of Smoke

The long oily summer of the BP oil spill is over, and now the investigation season has begun. BP itself has completed and issued a summary of its own internal investigation, posted for public access on its website. I have had time to read only the executive summary, but even that brief six-page document has technical details I don’t completely understand. However, the basic picture is clear: what happened last April 20 to cause the explosion, fire, deaths, and consequent oil spill that blackened miles of coastline and disrupted entire industries was not a simple one-failure event. Instead, it was a cascade of failures, both mechanical and human, that all went the wrong way to produce the tragedy.

At the time of the accident, the well drilling itself had been completed, and BP together with the actual operator of the rig, Transocean, were under pressure to cap off the well temporarily until a production structure could be put in place. Every modern oil well consists of a hole drilled in the rock, into which a long pipe called the casing is inserted. To keep the highly pressurized oil and gas where it belongs, most of the space (the “annulus” or ring-shaped area) between the outside of the casing and the raw hole is filled with a special cement, so the only place the “hydrocarbons” (BP’s term for oil and gas) can go is into the casing at a controlled location near the bottom of the well. At the very bottom of the casing between it and the bottom of the hole itself is something called a “shoe track.” I’m not sure what it is, but it looks in their drawing like a long can with holes at the bottom. The intention was to seal off this shoe track with the same cement that was being used to fill the space between the casing and the drill-hole wall.

Well, something went wrong: too much nitrogen in the cement, or something. But when the rig operators went to check the integrity of the cement seal by removing the heavy drill mud and replacing it with seawater to check for leaks, the pressure in the well rose beyond allowable limits.

The first place the accident could have been prevented had arrived. If the operators had put back the drill mud and figured out what was wrong instead of proceeding as if things were normal, they would have at least had a chance to avoid problems. But being in a hurry, they accepted the data as showing the cement seal was okay, even though it wasn’t, and eventually left lighter seawater in the well. This allowed high-pressure natural gas to enter the well.

Once the operators realized they had a problem, they sent signals down the well to operate the infamous blowout preventer (BOP), and connected the top of the well to a mud-gas separator on the rig itself. (As most readers probably know by now, the blowout preventer is a big piece of machinery on the ocean floor with two or three redundant systems designed to shut off the well in just such an eventuality as having high-pressure gas flow through it out of control.) Neither of these actions had the intended effect. For a couple of reasons (a bad solenoid valve and a low battery) the BOP failed to operate, and the gas flow coming from the well soon overwhelmed the mud-gas separator’s ability to deal with it. There was a separate overboard diverter line they could have used which might have kept the gas away from places it could ignite a little longer, but it wasn’t used.

Eyewitnesses who were in nearby vessels noted a high-pitched noise of escaping gas just before the explosion. By the time the gas got to areas that were not “electrically classified” (meaning certified as free of ignition sources), it was just a matter of time before an engine sucked in enough natural gas to set it afire. And the tragedy had begun.

The executive summary was written in dry, technical language in which people appear only in the passive voice (e. g. “The first well actions were to close. . .”). But as the immediate party responsible for day-to-day rig operations, Transocean is at fault for a number of things: poor training and management, careless maintenance of critical equipment such as blowout preventers, and allowing schedule pressures to take precedence over safety. But in the eyes of most laws, it is the owner of a rig, not just the operator, whose ultimate responsibility it is to see that the thing doesn’t befoul a good bit of the Gulf of Mexico, as the Deepwater Horizon failure did.

To their credit, BP did establish a fund to pay legitimate claims of damage resulting from the spill, and has paid out a lot of money already. But obviously, it would have been better to operate the rig like the 99+% of other deep-water rigs that successfully drill for and produce oil without major spills or fatal accidents. Besides fouling miles of shoreline, the carelessness exemplified by this tragedy of errors has blackened the reputation of the entire offshore drilling industry, and provoked a harsh government response in the form of the controversial moratorium on drilling operations. Some of the most vocal opponents of this ban were people along the coast that stand to be most affected by any accidents. But the reason for that is simple: offshore oil drilling is a big part of the gulf states’ economy. History may show that this decision was yet another bad judgment call in a cascade of bad judgment calls that began on April 20 on the rig.

At any rate, we will be finding out even more as the Presidential commission and other investigative bodies complete their findings. But already, the technical outlines of the accident are pretty clear. And pretty depressing.
