  • Kerry, the Democrats, and the Demagoguing of Global Warming

    Posted on March 16th, 2014 Helian 2 comments

    Secretary of State John Kerry appeared quite concerned about global warming during a recent visit to Indonesia, telling students,

    The bottom line is this: it is the same thing with climate change. In a sense, climate change can now be considered another weapon of mass destruction, perhaps even the worlds most fearsome weapon of mass destruction.

    A bit later, Harry Reid and his fellow Democrat senators pulled an all-night talkathon to sound the climate change alarm.  According to Reid, climate change is “the worst problem facing the world today.”  All this left reporter Susan Davis at USA Today scratching her head:

    The Democratic effort is cause for some confusion because these senators are calling for action in a chamber they control but without any specific legislation to offer up for a vote, or any timetable for action this year.

    As noted at Hot Air, the talkathon and Kerry’s bloviations were nothing but PR stunts:

    In other words, this is nothing but a stunt — and transparently so. Senate Democrats control all of the Senate committees, and what comes to the Senate floor. Boxer herself is the chair of the committee on environmental affairs, and could push through legislation any time she wants to the floor.

    In other words, it’s business as usual when it comes to environmental activism.  The pose is everything, and the reality is nothing.  The reality is that Kerry, Reid, and the rest are transparently indifferent to the problem of climate change, except as it serves them as a political tool.  If they really cared about it, they would have put a stop to illegal immigration long ago.  The carbon foot print per capita of the United States is four times that of Mexico, and the ratio is much greater for most of the other countries of origin.  If they really cared, they would put a stop to Nuclear Regulatory Commission stonewalling of innovative nuclear plant designs, not to mention grossly excessive litigation hurdles for plant construction.  If they really cared, they would get behind the shale-energy revolution which has cut 300 million tons of US greenhouse gas emissions by replacing heavily polluting coal with natural gas, a contribution greater than that of all the worlds solar and wind power installations combined.  In other words, they don’t care.

    It’s sad, because climate change actually is a potentially serious problem.  Kerry is just blowing hot air himself when he makes statements like,

    We should not allow a tiny minority of shoddy scientists and science and extreme ideologues to compete with scientific fact.

    The idea that someone like Kerry could distinguish “shoddy scientists” from “scientific fact” when it comes to climate change is beyond ludicrous.  What qualifies him to even make such a statement?  Certainly not the faintest understanding of current climate models.  The most powerful computers on earth couldn’t even come close to achieving a deterministic solution of the problem.  It involves billions of degrees of freedom in atmospheric and ocean conditions, and the necessary initial conditions are mostly either unknown or of limited accuracy.  The only way we can even begin to address the problem is with serious (and potentially inaccurate) data interpolation, and probabilistic computer models, the equivalent of “throwing dice” on a vast scale to see which numbers come up.  The statistical noise alone in such models renders it impossible to speak of “scientific facts” when it comes to climate change, but only a range of possible outcomes.  In other words, Kerry’s crude “alarmism” is an easy mark for the climate “denialism” on the other end of the ideological spectrum.  That’s too bad, because denying that any problem exists is just as bad as demagoguing it.

    We may not be able to speak of “scientific facts” when it comes to climate change.  We do know, however, that solar radiation passing through a simplified model of the atmosphere and striking an “average” patch of the earth’s surface will raise the temperature of that atmosphere in proportion to the concentration of greenhouse gases.  The best computer models we have are not perfect, but they’re not useless either, and they predict that significant warming will occur over the coming decades.  In other words, we can’t speak of “facts” or certainty here, but we can say that there is a substantial risk that significant human-induced climate change will occur.  The effects might be benign, outweighed by the same factors that have driven variations in the earth’s climate throughout its history.  They might also be disastrous.  Given that earth is the only planet we have to live on at the moment, it seems foolhardy to rock the boat.

    Under the circumstances, Kerry, Reid, and the rest might want to think twice about the value of crying “wolf” to score cheap political points, when it’s clear that they have no intention of seriously addressing the problem.  Particularly at the end of a 15 year pause in the rate of increase of global temperatures, the result, already much in evidence, will be an increase in cynicism and skepticism that the problem is real.  The resulting reluctance to sacrifice other priorities to address it may come back to haunt the alarmists if, as the boy in the story discovered, the “wolf” turns out to be real.

    What to do?  Some of the most effective solutions are precisely what the alarmists who bray the loudest don’t want to do.  End significant immigration to countries with the most emissions per capita, for one.  Lead in the introduction and adoption of more efficient and safer nuclear technologies and the expansion of nuclear capacity instead of blocking it for another.   Instead, the wildly misnomered “Greens” in Germany are shutting down the nuclear plants in that country, with the entirely predictable result that Germany is currently planning to build 26 new, heavily polluting, coal-fired power plants to replace them.  Divert heavy subsidies for existing solar and wind technologies to investment in green technology research and development.  As those famously “green” Germans discovered once again, taxing the poor to finance the solar energy hobbies of the rich in a cloudy country whose capital lies above the 52nd parallel of latitude is a dubious proposition.  The cost of electricity there after years of massive subsidies to solar and a nuclear shutdown is now twice as high as in heavily nuclear France.  As noted in an article in the Frankfurter Allgemeine Zeitung, the burden of these skyrocketing costs is falling disproportionately on the backs of those least able to afford them.

    Beyond that, we might want to get serious about finding another habitable planet, and developing the technology to get there.  We’ve been doing a lot of rocking the boat lately.  It would behoove us to have an alternative in case it eventually tips over, and the sooner the better.





  • The Derb on Japan’s “Demographic Catastrophe”

    Posted on February 16th, 2014 Helian 5 comments

    John Derbyshire’s reaction to the BBC documentary, “No Sex Please, We’re Japanese,” about Japan’s “demographic catastrophe” is probably somewhat different from what the producers had in mind.  In short, he considers it a feature, not a bug.  In fact, he thinks “The 21st Century Might Belong to Japan” because they are biting the demographic bullet now.

    The documentary follows reporter Anita Rani, a Briton of Indian descent, as she leads us through a series of nightmares in the demographic basket case that is modern Japan.  There is Yubari, a coal-mining town in the north, that once teamed with children, but whose maternity ward has been converted to a dusty storeroom.  There are a pair of late-30’s geeks whose main love interests, schoolgirls aged 15 and 17, reside in the virtual world of a Nintendo box.  There is a prison that is rapidly becoming a geriatric ward.  And finally we cut to the chase.  In a conversation with American-born economist Kathy Matsui, Rani observes sagely, ““Immigration.  Surely that’s the solution that’s staring them in the face.”  Matsui agrees, noting the extreme indebtedness of Japan, its stagnant economy, the increasingly unbearable cost of caring for a rapidly aging population without a steady supply of young taxpayers to milk, etc., etc.  However, she notes, “There is an order of steps that need to occur” for mass immigration to become acceptable in a traditional society like Japan.  Right, just like the order of steps that take you to the top of a gallows.

    According to Derbyshire, “Mass immigration at best postpones the day of reckoning for a few years,” and by biting the bullet now, Japan may, “…speed off ahead of us into some new socio-economic order suited to low population levels and better age ratios, as we struggle with the transition they have already mastered.”  Regardless of how she masters her economic problems, Japan is fortunate indeed to have a “traditional” society that discourages immigration.  As Jayman put it in a recent tweet, “we should be so lucky” as to have a similar problem.  I can but hope that Japan never becomes so suicidal as to take the “order of steps” to mass immigration.

    The peddlers of the “demographic catastrophe” scare stories would have us believe that there can be nothing worse than stagnant or declining economies.  Actually, there is something worse; failure to survive.  You don’t have to go back too many years to come to a time when this was actually a serious concern for Japan.  Just read some of the books and magazines about her published in the 30’s when her population was half what it is today.  However, with the agricultural technology available at the time, it appeared that there was no way she could continue to feed her population if it grew much beyond that.  We now know how she attempted to solve the problem, and the results of that attempt.  Now we are supposed to be shaking in our boots if her population returns to that level at the turn of the next century.

    Apparently we are to believe that such unfortunate byproducts of continuous population growth are all behind us now.  Search the Internet and you can find articles claiming that the planet can easily accommodate 10, 50, or even 100 billion people.  As a wag on the nightly news once put it, “maybe so, but who wants to eat standing up?”  What’s amazing is that this stuff is being eagerly swallowed on both the right and the left.  The Beeb, of course, is reliably leftist, like most of the rest of the western European media, and unlimited immigration is one of the boards that makes up the ideological box that the left lives in these days.  It’s as if the denizens of that box are a bunch of lemmings who can’t wait to commit demographic suicide, or serve as promoters for the next wave of civil wars.

    Consider, for example, the case of Switzerland, whose voters recently decided to apply some reasonable limits to immigration from the rest of the EU.  The German papers and news websites, which I happen to follow, became positively hysterical.  I haven’t seen much to compare with it since the most recent eruption of anti-American hate in the late 90’s and early 2000’s.  Among other things, the evil Swiss were supposed to be hicks from the back woods, consumed by greed.  Their vibrant economy was built with the wealth accumulated by the Nazis and assorted other dictators, etc.  It was a classic example of the response of an ingroup to perceived attack by an outgroup.

    Oddly enough, the right is playing a similar tune.  Anyone who thinks the planet might be better off with a smaller population must be “anti-Life.”  I have personally heard a retired Army 4-star general defend unlimited immigration, supposedly because it’s necessary to support a strong economy and, with it, a powerful military.  I’m of a different opinion.  I’d rather not rock the boat.

    Global warming may or may not be a reality.  We may or may not run out of clean water.  We may or may not be able to produce enough food to feed the planet’s increasing population.  We may or may not run out of affordable energy in the next few hundred years.  It seems to me the pertinent question is, “Why take chances?”

    Does that mean that the readers of this little blog should refrain from having as many children as possible?  Of course not!  Heaven forefend, gentle readers, that any of you should ever become defective biological units.  However, Mother Nature, in her wisdom, enabled us to perceive the world in terms of ingroups and outgroups, with different rules and versions of morality applying to each.  To paraphrase General Patton, the idea isn’t to commit genetic suicide yourself.  The idea is to get the other poor, dumb bastard to commit genetic suicide.  The result will be a world with a manageable population where you will be able to pursue your own version of “human flourishing” in peace.  As for Japan, I don’t doubt that she is still producing men (and women) whose love interests don’t reside in Nintendo boxes.  In time, their children, and their children’s children, will inherit the islands.  When they do, the population demographics will likely take a turn for the better.

    Of course, I’m supplying you with a “should” here, and as my readers know, I don’t admit the existence of objective “shoulds.”  Take it with a grain of salt, if you like.  It certainly won’t bother me.  I’ve made my reasons for preferring genetic survival to a life in which I make a “meaningful contribution” to the rest of mankind, and then croak, clear enough in earlier posts.  My point is, if you happen to share this whim, this preference for survival with me, don’t be concerned the next time you see some feminist harridan railing about the evils of having children.  Why on earth would you ever attempt to persuade her she’s wrong?  The best response is to smile, get a room, and get busy.

    UPDATE:  More on the Derb’s article over at Occam’s Razor


  • Science vs. Ideology in Genetics, in which Richard Dawkins and Professor Ceiling Cat Admonish David Dobbs

    Posted on December 8th, 2013 Helian 1 comment

    Cultural determinism is like the Paris fashions.  It defies ridicule.  The idea is so useful that it won’t drown, despite the torrent of contradictory facts it has been submerged under lately.  The cobbling of utopias is great fun, and utopia is ever so much more plausible if only everything can be changed to the heart’s desire by culture and environment.  One of the more flamboyant examples of the phenomenon recently turned up in Aeon Magazine in the form of an article penned by science journalist David Dobbs.

    The title of the article, Die, Selfish Gene, Die, is provocative enough.  The Selfish Gene, of course, was the subject of a book with that title by Richard Dawkins.  Rubbing salt in the wound, Dobbs adds the byline, “The selfish gene is one of the most successful science metaphors ever invented. Unfortunately, it’s wrong.”  All this irritated Dawkins’ friend Jerry Coyne, to the point that he not only read the rather lengthy article, but penned a pair of rebuttals on his Why Evolution is True website.  It wasn’t hard.

    Dobbs’ claim that Dawkins’ selfish gene version of evolution is wrong was based on his embrace of the idea of genetic accommodation.  Coyne (known to his students as Professor Ceiling Cat, for reasons that will be obvious to anyone who visits his blog) described the idea in his second rebuttal as follows;

    Today’s discussion is on what Dobbs and some of the heroes of his piece (especially Dr. Mary Jane West-Eberhard) see as the truly novel and non-Darwinian refutation of the selfish gene idea: the idea of genetic accommodation.  “Genetic accommodation” has other names: it’s also been called “The Baldwin Effect” and “genetic assimilation.”  But all of these names refer to a single mechanism: instead of existing genetic variation being subject to natural selection in an existing or changing environment, the environment itself evokes phenotypic (not genetic) variation, which is then somehow fixed in the species’ genome.

    Dobbs’ version of this idea leads him to some rather startling assertions.  For example, he writes,

    Gene expression is what makes a gene meaningful, and it’s vital for distinguishing one species from another.  We humans, for instance, share more than half our genomes with flatworms; about 60 per cent with fruit flies and chickens; 80 per cent with cows; and 99 per cent with chimps.  Those genetic distinctions aren’t enough to create all our differences from those animals – what biologists call our phenotype, which is essentially the recognizable thing a genotype builds.  This means that we are human, rather than wormlike, flylike, chickenlike, feline, bovine, or excessively simian, less because we carry different genes from those other species than because our cells read differently our remarkably similar genomes as we develop from zygote to adult.  The writing varies – but hardly as much as the reading.

    Great shades of Trofim Lysenko!  One can almost see the great Soviet con man in one of his Siberian laboratories, turning out a race of centaurs by astutely tweaking the “reading” of the genes of a zebra.  Where is Dobbs going with this?  Let’s cut to the chase and have a look at his thumbnail sketch of genetic accommodation:

    There lies the quick beating heart of her (Mary Jane West-Eberhard’s) argument: the gene follows. And one of the ways the gene follows is through this process called genetic accommodation. Genetic accommodation is a clunky term for a graceful process. It takes a moment to explain. But bear with me a moment, and you’ll understand how you, dear reader, could evolve into a fast and deadly predator.

    Genetic accommodation involves a three-step process.

    First, an organism (or a bunch of organisms, a population) changes its functional form — its phenotype — by making broad changes in gene expression. Second, a gene emerges that happens to help lock in that change in phenotype. Third, the gene spreads through the population.

    For example, suppose you’re a predator. You live with others of your ilk in dense forest. Your kind hunts by stealth: you hide among trees, then jump out and snag your meat. You needn’t be fast, just quick and sneaky.

    You get faster. You mate with another fast hunter, and your kids, hunting with you from early on, soon run faster than you ever did.

    Then a big event — maybe a forest fire, or a plague that kills all your normal prey — forces you into a new environment. This new place is more open, which nixes your jump-and-grab tactic, but it contains plump, juicy animals, the slowest of which you can outrun if you sprint hard. You start running down these critters. As you do, certain genes ramp up expression to build more muscle and fire the muscles more quickly. You get faster. You’re becoming a different animal. You mate with another fast hunter, and your kids, hunting with you from early on, soon run faster than you ever did. Via gene expression, they develop leaner torsos and more muscular, powerful legs. By the time your grandchildren show up, they seem almost like different animals: stronger legs, leaner torsos, and they run way faster than you ever did. And all this has happened without taking on any new genes.

    Then a mutation occurs in one grandkid. This mutation happens to create stronger, faster muscle fibres. This grandchild of yours can naturally and easily run faster than her fastest siblings and cousins. She flies. Her children inherit the gene, and because their speed wows their mating prospects, they mate early and often, and bear lots of kids. Through the generations, this sprinter’s gene thus spreads through the population.

    Now the thing is complete. Your descendants have a new gene that helps secure the adaptive trait you originally developed through gene expression alone. But the new gene didn’t create the new trait. It just made it easier to keep a trait that a change in the environment made valuable. The gene didn’t drive the train; it merely hopped aboard.

    In fact, all this is so banal, and so lacking in any serious departure from anything Dawkins said in The Selfish Gene, that Coyne apparently assumed that he’d missed something, and accused Dobbs of Lamarckism.  After all, if he wasn’t at least implying Lamarckism between the lines, there isn’t the shadow of a hook in this scenario on which to hang the claim that such “genetic accommodation” is in any way revolutionary, non-Darwinian, or non-Dawkinsian.  In fact, if you read the passage closely, you’ll see there’s nothing Lamarckian about it at all.  The kids and grandkids don’t get faster and stronger by inheritance or acquired characteristics, but merely by hanging out with their parental role models.  Evidently Dawkins himself noticed, because at this point he chimed in and wrote his own rebuttal, patiently Fisking Dobbs article, and quite reasonably pointing out that there was nothing in all this that contradicted Darwin or himself in any substantial way at all.

    Coyne and Dawkins concluded from all this that Dobbs was merely grandstanding.  As Dawkins put it, his article was,

    …infected by an all-too-common journalistic tendency, the adversarial urge to (presumably) boost circulation and harvest clicks by pretending to be controversial. You have a topic X, which you laudably want to pass on to your readers. But it’s not enough that X is interesting in its own right; you have to adversarialise it: yell that X is revolutionary, new, paradigm-shifting, dramatically overthrowing some Y.

    True enough, but as scientists often do, Dawkins sees the basic absurdity of the article clearly enough, but fails to see that it is absurd, not because it is bad science, but because it is an ideological morality tale.  Let’s allow Dobbs to explain the moral of the story in his own words:

    The gene does not lead, it follows.

    And ‘evolution is not about single genes’ (West-Eberhard) says.  It’s about genes working together.

    It’s not a selfish gene or a solitary genome.  It’s a social genome.

    Not the selfish gene, but the social genome.

    And so, thanks to the environment, the collective once again triumphs over the “selfish” individual.  If you don’t get the ideological point, dear reader, I’m not going to spell it out for you.  I’ll let the ideologues do that for themselves.  See, for example, Drugged Individualism, in the November 1934 issue of the American Mercury, or The Myth of Individuality (by Theodore Dreiser, no less) in the March issue of the same year.  The hive mind hasn’t changed much in 80 years.


  • New Reactors in the UK and the Future of Nuclear Power

    Posted on October 22nd, 2013 Helian 2 comments

    A consortium led by France’s EDF Energy, including Chinese investors, has agreed with the government of the UK on terms for building a pair of new nuclear reactors at Hinkley Point in the southwest of the country, not far from Bristol.  If a final investment decision is made some time next year, and the plants are actually built, they will probably be big (about 1600 Megawatts) pressurized water reactors (PWR’s) based on the French company Areva’s EPR design.  These are supposed to be  (and probably are) safer, more efficient, and more environmentally friendly than earlier designs.  In general, I tend to be pro-nuclear.  I would certainly feel a lot safer living next to a nuclear plant than a coal plant.  However, I’m a bit ambivalent about these new starts.  I think we could be a lot smarter in the way we implement nuclear power programs.

    Reactors of the type proposed will burn uranium.  Natural uranium consists mostly of two isotopes, U235 and U238, and only U235 can be burnt directly in a nuclear reactor.  Why?  The answer to that question depends on something called “the binding energy of the last neutron.”  Think of a neutron as a bowling ball, and the nucleus of a uranium atom as a deep well.  If the bowling ball happens to roll into the well, it will drop over the edge, eventually smacking into the bottom, and releasing the energy it acquired due to the acceleration of gravity in the process.  The analogous force in the nucleus of a uranium atom is the nuclear force, incomparably greater than the force of gravity, but it acts in much the same way.  The neutron doesn’t notice this very short range force until it gets very close to the nucleus, or “lip of the well,” but when it does, it “falls in” and releases the energy acquired in the process in much the same way.  This energy is what I’ve referred to above as “the binding energy of the last neutron.”

    When this binding energy is released in the nucleus, it causes it to wiggle and vibrate, something like a big drop of water falling through the air.  In the case of U235, the energy is sufficient to cause this “liquid drop” to actually break in two, or “fission.”  Such isotopes are referred to as “fissile.”  In U238, the binding energy of the last neutron alone is not sufficient to cause fission, but the isotope can still actually fission if the neutron happens to be moving very fast when it hits the nucleus, bringing some of its own energy to the mix.  Such isotopes, while not “fissile,” are referred to as “fissionable.”  Unfortunately, the isotope U235 is only 0.7 percent of natural uranium.  Once it’s burnt, the remaining U238 is no longer useful for starting a nuclear chain reaction on its own.

    That would be the end of the story as far as conventional reactors are concerned, except for the fact that something interesting happens to the U238 when it absorbs a neutron.  As mentioned above, it doesn’t fission unless the neutron is going very fast to begin with.  Instead, with the extra neutron, it becomes U239.  However, U239 is unstable, and decays into neptunium 239, which further decays into plutonium 239, or Pu239.  In Pu239 the binding energy of the last neutron IS enough to cause it to fission.  Thus, conventional reactors burn not only U235, but also some of the Pu239 that is produced in this way.  Unfortunately, they don’t produce enough extra plutonium to keep the reactor going, so only a few percent of the U238 is “burnt” in addition to the U235 before the fuel has to be replaced and the old fuel either reprocessed or stored as radioactive waste.  Even though a lot of energy is locked up in the remaining U238, it is usually just discarded or used in such applications as the production of heavy armor or armor piercing munitions.  In other words, the process is something like throwing a log on your fireplace, then fishing it out and throwing it away when only a small fraction of it has been burnt.

    Can anything be done about it?  It turns out that it can.  The key is neutrons.  They not only cause the U235 and Pu239 to fission, but also produce Pu239 via absorption in U238.  What if there were more of them around?  If there were enough, then enough new Pu239 could be produced to replace the U235 and old Pu239 lost to fission, and a much greater fraction of the U238 could be converted into useful energy.  A much bigger piece of the “log” could be burnt.

    As a matter of fact, what I’ve described has actually been done, in so-called breeder reactors.  To answer the question “How?” it’s necessary to understand where all those neutrons come from to begin with.  In fact, they come from the fission process itself.  When an atom of uranium or plutonium fissions, it releases an average of something between 2 and 3 neutrons in the process.  These, in turn, can cause other fissions, keeping the nuclear chain reaction going.  The chances that they actually will cause another fission depends, among other things, on how fast they are going.  In general, the slower the neutron, the greater the probability that it will cause another fission.  For that reason, the neutrons in nuclear reactors are usually “moderated” to slower speeds by allowing them to collide with lighter elements, such as hydrogen.  Think of billiard balls.  If one of them hits another straight on, it will stop, transferring its energy to the second ball.  Much the same thing happens in neutron “moderation.”

    However, more neutrons will be produced in each fission if the neutrons aren’t heavily moderated, but remain “fast.”  In fact, enough can be produced, not only to keep the chain reaction going, but to convert more U238 into useful fuel via neutron absorption than is consumed.  That is the principle of the so-called fast breeder reactor.  Another way to do the same thing is to replace the U238 with the more plentiful naturally occurring element thorium 232.  When it absorbs a neutron, it eventually decays into U233, which, like U235, is fissile.  There are actually many potential advantages to this thorium breeding cycle, such as potentially greater resistance to nuclear weapons proliferation, the ability to run the process at slower average neutron speeds, allowing smaller reactor size and easier control, less production of dangerous, long-lived transuranic actinides, such as plutonium and americium, etc.  In fact, if enough neutrons are flying around, they will fission and eliminate these actinides.  It turns out that’s very important, because they’re the nastiest components of nuclear waste.  If they could be recycled and burned, the amount of residual radiation from the waste produced by operating a nuclear plant for 30 or 40 years could be reduced to a level below that of the original uranium or thorium ore in a matter of only a few hundred years, rather than the many thousands that would otherwise be necessary.

    So breeders can use almost all the potential energy in uranium or thorium instead of just a small fraction, while at the same time minimizing problems with radioactive waste.  What’s not to like?  Why aren’t we doing this?  The answer is profit.  As things now stand, power from breeder reactors of the type I’ve just described would be significantly more expensive than that from conventional reactors like EPR.  EPR’s would use enriched natural uranium, which is still relatively cheap and plentiful.  They would require no expensive reprocessing step.  Ask an industry spokesman, and they will generally assure you (and quite possibly believe themselves, because self-interest has always had a strong delusional effect) that we will never run out of natural uranium, that the radioactive danger from conventional reactor waste has been grossly exaggerated, and there is no long-term proliferation danger from simply discarding plutonium-laced waste somewhere and letting it decay for several thousand years.  I’m not so sure.

    Now, I have no problem with profit, and I find Hollywood’s obsession with the evils of large corporations tiresome, but I really do think this is one area in which government might actually do something useful.  It might involve some mix of increased investment in research and development of advanced reactor technology, including the building of small demonstration reactors, continued robust support for the nuclear Navy, and eliminating subsidies on new conventional reactors.  Somehow, we managed to build scores of research reactors back in the 50’s, 60’s and 70’s.  It would be nice if we could continue building a few more now and then, not only for research into breeder technology, but as test beds for new corrosion and radiation resistant materials and fuels, exploration of high temperature gas-cooled reactors that could not only produce electricity but facilitate the production of hydrogen from water and synthetic natural gas from carbon dioxide and coal, both processes that are potentially much more efficient at high temperatures, and even fusion-fission hybrids if we can ever get fusion to work.

    We aren’t going to run out of energy any time soon, but there are now over 7 billion people on the planet.  Eventually we will run out of fossil fuels, and depending entirely on wind, solar and other renewables to take up the slack seems a little risky to me.  Wasting potential fuel for the reactors of the future doesn’t seem like such a good idea either.  Under the circumstances, keeping breeder technology on the table as a viable alternative doesn’t seem like a bad idea.

  • Fusion Follies at Der Spiegel

    Posted on October 19th, 2013 Helian No comments

    Who says there’s no such thing as German humor?  Take, for example, some of the comments left by Teutonic wags after an article about the recent fusion “breakthrough” reported by scientists at Lawrence Livermore National Laboratory working on the National Ignition Facility (NIF).  One of the first was left by one of Germany’s famous “Greens,” who was worried about the long term effects of fusion energy.  Very long term.  Here’s what he had to say:

    So nuclear fusion is green energy, is it?  The opposite is true.  Nuclear fusion is the form of energy that guarantees that any form of Green will be forever out of the question.  In comparison, Chernobyl is a short-lived joke!  Why?  Have you ever actually considered what will be “burned” with fusion energy?  Hydrogen, one of the two components of water, (and a material without which life is simply impossible)!  Nuclear fusion?  I can already see the wars over water coming.  And, by the way, the process is irreversible.  Once hydrogen is fused, it’s gone forever.  Nothing and no one will ever be able to make water out of it ever again!

    I’m not kidding!  The guy was dead serious.  Of course, this drew a multitude of comments from typical German Besserwisser (better knowers), such as, “If you don’t have a clue, you should shut your trap.”  However, some of the other commenters were more light-hearted.  for example,

    No, no, no.  What eu-fan (the first commenter) doesn’t seem to understand is that this should be seen as a measure against the rise in sea level that will result from global warming.  Less hydrogen -> less water -> reduced sea level -> everything will be OK.

    Another hopeful commenter adds,

    …if it ever actually does succeed, this green fusion, can we have our old-fashioned light bulbs back?

    Noting that the fusion of hydrogen produces helium, another commenter chimes in,

    So, in other words, if a fusion reactor blows up, the result will be a global bird cage:  The helium released will make us all talk like Mickey Mouse!

    In all seriousness, the article in Der Spiegel about the “breakthrough” wasn’t at all bad.  The author actually bothered to ask a local fusion expert, Sibylle Günter, Scientific Director of the Max Planck Institute for Plasma Physics, about Livermore’s “breakthrough.”  She replied,

    The success of our colleagues (at Livermore) is remarkable, and I don’t want to belittle it.  However, when one speaks of a “breakeven point” in the classical sense, in which the fusion energy out equals the total energy in, they still have a long way to go.

    That, of course, is entirely true.  The only way one can speak of a “breakthough” in the recent NIF experiments is by dumbing down the accepted definition of “ignition” from “fusion energy out equals laser energy in” to “fusion energy out equals energy absorbed by the target,” a much lower amount.  That didn’t deter many writers of English-language reports, who couldn’t be troubled to fact check Livermore’s claims with the likes of Dr. Günter.  In some cases the level of fusion wowserism was extreme.  For example, according to the account at Yahoo News,

    After fifty years of research, scientists at the National Ignition Facility (NIF) in Livermore, have made a breakthrough in harnessing and controlling fusion.


    According to the BBC, NIF conducted an experiment where the amount of energy released through the fusion reaction was more than the amount of energy being absorbed by it. This process is known as “ignition” and is the first time it has successfully been done anywhere in the world.

    I’m afraid not.  The definition of “ignition” that has been explicitly accepted by scientists at Livermore is “fusion energy out equals laser energy in.”  That definition puts them on a level playing field with their magnetic fusion competitors.  It’s hardly out of the question that the NIF will reach that goal, but it isn’t there yet.  Not by a long shot.


  • Another Fusion Tease?

    Posted on October 10th, 2013 Helian No comments

    It has always seemed plausible to me that some clever scientist(s) might find a shortcut to fusion that would finally usher in the age of fusion energy, rendering the two “mainstream” approaches, inertial confinement fusion (ICF) and magnetic fusion, obsolete in the process.  It would be nice if it happened sooner rather than later, if only to put a stop to the ITER madness.  For those unfamiliar with the field, the International Thermonuclear Experimental Reactor, or ITER, is a gigantic, hopeless, and incredibly expensive white elephant and welfare project for fusion scientists currently being built in France.  In terms of pure, unabashed wastefulness, think of it as a clone of the International Space Station.  It has always been peddled as a future source of inexhaustible energy.  Trust me, nothing like ITER will ever be economically competitive with alternative energy sources.  Forget all your platitudes about naysayers and “they said it couldn’t be done.”  If you don’t believe me, leave a note to your descendants to fact check me 200 years from now.  They can write a gloating refutation to my blog if I’m wrong, but I doubt that it will be necessary.

    In any case, candidates for the hoped for end run around magnetic and ICF keep turning up, all decked out in the appropriate hype.  So far, at least, none of them has ever panned out.  Enter two stage laser fusion, the latest pretender, introduced over at NextBigFuture with the assurance that it can achieve “10x higher fusion output than using the laser directly and thousands of times better output than hitting a solid target with a laser.”  Not only that, but it actually achieved the fusion of boron and normal hydrogen nuclei, which produces only stable helium atoms.  That’s much harder to achieve than the usual deuterium-tritium fusion between two heavy isotopes of hydrogen, one of which, tritium, is radioactive and found only in tiny traces in nature.  That means it wouldn’t be necessary to breed tritium from the fusion reactions just to keep them going, one of the reasons that ITER will never be practical.

    Well, I’d love to believe this is finally the ONE, but I’m not so sure.  The paper describing the results NBF refers to was published by the journal Nature Communications.  Even if you don’t subscribe, you can click on the figures in the abstract and get the gist of what’s going on.  In the first place, one of the lasers has to accelerate protons to high enough energies to overcome the Coulomb repulsion of the stripped (of electrons) boron nuclei produced by the other laser.  Such laser particle accelerators are certainly practical, but they only work at extremely high power levels.  In other words, they require what’s known in the business as petawatt lasers, capable of achieving powers in excess of a quadrillion (10 to the 15th power) watts.  Power comes in units of energy per unit time, and such lasers generally reach the petawatt threshold by producing a lot of energy in a very, very short time.  Often, we’re talking picoseconds (trillionths of a second).

    Now, you can do really, really cool things with petawatt lasers, such as pulling electron positron pairs right out of the vacuum.  However, their practicality as drivers for fusion power plants, at least in their current incarnation, is virtually nil.  The few currently available, for example, at the University of Rochester’s Laboratory for Laser Energetics, the University of Texas at Austin, the University of Nevada at Reno, etc., are glass lasers.  There’s no way they could achieve the “rep rates” (shot frequency) necessary for useful energy generation.  Achieving lots of fusions, but only for a few picoseconds, isn’t going to solve the world’s energy problems.

    As it happens, conventional accelerators can also be used for fusion.  As a matter of fact, it’s a common way of generating neutrons for such purposes as neutron radiography.  Unfortunately, none of the many fancy accelerator-driven schemes for producing energy that people have come up with over the years has ever worked.  There’s a good physical reason for that.  Instead of using their energy to overcome the Coulomb repulsion of other nuclei (like charges repel, and atomic nuclei are all positively charged), and fuse with them, the accelerated particles prefer to uselessly dump that energy into the electrons surrounding those nuclei.  As a result, it has always taken more energy to drive the accelerators than could be generated in the fusion reactions.  That’s where the “clever” part of this scheme comes in.  In theory, at least, all those pesky electrons are gone, swept away by the second laser.  However, that, too, is an energy drain.  So the question becomes, can both lasers be run efficiently enough and with high enough rep rates and with enough energy output to strip enough boron atoms to get enough of energy out to be worth bothering about, in amounts greater than that needed to drive the lasers?  I don’t think so.  Still, it was a very cool experiment.

  • Fusion Update: The NIF Inches Closer to Ignition

    Posted on August 30th, 2013 Helian No comments

    In a recent press release, Lawrence Livermore National Laboratory (LLNL) announced that it had achieved a yield of 3 x 1015 neutrons in the latest round of experiments at its National Ignition Facility, a giant, 192-beam laser facility designed, as its name implies, to achieve fusion ignition.  That’s nowhere near “ignition,” but still encouraging as it’s three times better than results achieved in earlier experiments.

    The easiest way to achieve fusion is with two heavy isotopes of hydrogen; deuterium, with a nucleus containing one proton and one neutron, and tritium, with a nucleus containing one proton and two neutrons.  Deuterium is not radioactive, and occurs naturally as about one atom to every 6400 atoms of “normal” hydrogen, with a nucleus containing only a single proton.  Tritium is radioactive, and occurs naturally only in tiny trace amounts.  It has a half-life (the time it takes for half of a given amount to undergo radioactive decay) of 12.3 years, and must be produced artificially.  When tritium and deuterium fuse, they release a neutron, a helium nucleus, or alpha particle, and lots of energy (17.6 million electron volts).

    Fortunately (because otherwise it would be too easy to blow up the planet), or unfortunately (if you want to convert the energy into electricity), fusion is hard.  The two atoms don’t like to get too close, because their positively charged nuclei repel each other.  Somehow, a way must be found to make the heavy hydrogen fuel material very hot, causing the thermal motion of the atoms to become very large.  Once they start moving fast enough, they can smash into each other with enough momentum to overcome the repulsion of the positive nuclei, allowing them to fuse.  However, the amount of energy needed per atom is huge, and when atoms get that hot, the last thing they want to do is stay close to each other (think of what happens in the detonation of high explosive.)  There are two mainstream approaches to solving this problem; magnetic fusion, in which the atoms are held in place by powerful magnetic fields while they are heated (the approach being pursued at ITER, the International Thermonuclear Experimental Reactor, currently under construction in France), and inertial confinement fusion (ICF), where the idea is to dump energy into the fuel material so fast that its own inertia holds it in place long enough for fusion to occur.  The NIF is an ICF facility.

    There are various definitions of ICF “ignition,” but, in order to avoid comparisons of apples and oranges between ICF and magnetic fusion experiments, LLNL has explicitly accepted the point at which the fusion energy out equals the laser energy in as the definition of ignition.  In the experiment referred to above, the total fusion energy release was about 10,000 joules, give or take.  Since the laser energy in was around 1.7 million joules, that’s only a little over one half of one percent of what’s needed for ignition.  Paltry, you say?  Not really.  To understand why, you have to know a little about how ICF experiments work.

    Recall that the idea is to heat the fuel material up so fast that its own inertia holds it in place long enough for fusion to occur.  The “obvious” way to do that would be to simply dump in enough laser energy to heat all the fuel material to fusion temperatures at once.  Unfortunately, this “volumetric heating” approach wouldn’t work.  The energy required would be orders of magnitude more than what’s available on the NIF.  What to do?   Apply lots and lots of finesse.  It turns out that if a very small volume or “hot spot” in the fuel material can be brought to fusion conditions, the alpha particles released in the fusion reactions might carry enough energy to heat up the nearby fuel to fusion conditions as well.  Ideally, the result would be an alpha “burn wave,” moving out through the fuel, and consuming it all.  But wait, it ain’t that easy!  An efficient burn wave will occur only if the alphas are slammed to a stop and forced to dump their energy after traveling only a very short distance in the cold fuel material around the hot spot.  Their range is too large unless the fuel is first compressed to a tiny fraction of its original volume, causing its density to increase by orders of magnitude.

    In other words, to get the fuel to fuse, we need to make it very hot, but we also need to compress it to very high density, which can be done much more easily and efficiently if the material is cold!  Somehow, we need to keep the fuel “cold” during the compression process, and then, just at the right moment, suddenly heat up a small volume to fusion conditions.  It turns out that shocks are the answer to the problem.  If a train of four shocks can be set off in the fuel material as it is being compressed, or “imploded,” by the lasers, precisely timed so that they will all converge at just the right moment, it should be possible, in theory at least, to generate a hot spot.  If the nice, spherical symmetry of the fuel target could be maintained during the implosion process, everything should work just fine.  The NIF would have more than enough energy to achieve ignition.  But there’s the rub. Maintaining the necessary symmetry has turned out to be inordinately hard.  Tiny imperfections in the target surface finish, small asymmetries in the laser beams, etc., lead to big deviations from perfect symmetry in the dense, imploded fuel.  These asymmetries have been the main reason the NIF has not been able to achieve its ignition goal to date.

    And that’s why the results of the latest round of experiments haven’t been as “paltry” as they seem.  As noted in the LLNL press release,

    Early calculations show that fusion reactions in the hot plasma started to self-heat the burning core and enhanced the yield by nearly 50 percent, pushing close to the margins of alpha burn, where the fusion reactions dominate the process.

    “The yield was significantly greater than the energy deposited in the hot spot by the implosion,” said Ed Moses, principle associate director for NIF and Photon Science. “This represents an important advance in establishing a self-sustaining burning target, the next critical step on the path to fusion ignition on NIF.”

    That’s not just hype.  If the self-heating can be increased in future experiments, it may be possible to reach a threshold at which the alpha heating sets off a burn wave through the rest of the cold fuel, as described above.  In other words, ignition is hardly a given, but the guys at LLNL still have a fighting chance.  Their main challenge may be to stem the gradual evaporation of political support for NIF while the experiments are underway.  Their own Senator, Diane Feinstein, is anything but an avid supporter.  She recently turned down appeals to halt NIF budget cuts, and says the project needs to be “reassessed” in light of the failure to achieve ignition.

    Such a “reassessment” would be a big mistake.  The NIF was never funded as an energy project.  Its support comes from the National Nuclear Security Administration (NNSA), a semi-autonomous arm of the Department of Energy charged with maintaining the safety and reliability of the nation’s nuclear arsenal.  As a tool for achieving that end, the NIF is without peer in any other country.  It has delivered on all of its performance design goals, including laser energy, illumination symmetry, shot rate, the precision and accuracy of its diagnostic instrumentation, etc.  The facility is of exceptional value to the weapons program even if ignition is never achieved.  It can still generate experimental conditions approaching those present in an exploding nuclear device, and, along with the rest of our suite of “above-ground experimental facilities,” or AGEX, it gives us a major leg up over the competition in maintaining our arsenal and avoiding technological surprise in the post-testing era.

    Why is that important?  Because the alternative is a return to nuclear testing.  Do you think no one at NNSA wants to return to testing, and that the weapon designers at the National Weapons Laboratories wouldn’t jump at the chance?  If so, you’re dreaming.  It seems to me we should be doing our best to keep the nuclear genie in the bottle, not let it out.  Mothballing the NIF would be an excellent start at pulling the cork!

    I understand why the guys at LLNL are hyping the NIF’s potential as a source of energy.  It’s a lot easier to generate political support for lots of electricity with very little radioactive waste and no greenhouse gases than for maintaining our aging arsenal of nuclear weapons.  However, IMHO, ICF is hopeless as a source of electricity, at least for the next few hundred years.  I know many excellent scientists will disagree, but many excellent scientists are also prone to extreme wishful thinking when it comes to rationalizing a technology they’ve devoted their careers to.  Regardless, energy hype isn’t needed to justify the NIF.  It and facilities like it will insure our technological superiority over potential nuclear rivals for years to come, and at the same time provide a potent argument against the resumption of nuclear testing.

  • Academic Left Update: Party Time at Swarthmore

    Posted on May 13th, 2013 Helian 2 comments

    Paul Gross and Norman Levitt published their now classic Higher Superstition: The Academic Left and Its Quarrels with Science almost two decades ago.  The book described the flipping and flopping of the various species of self-appointed saviors of mankind on campus left high and dry by the collapse of Marxism.  In the absence of that grand, unifying philosophy, the authors found them running about like so many chickens with their heads cut off, engaged in internecine warfare, and chasing after the various chimeras of postmodernism, eco-extremism, radical feminism, anti-racist racism, etc.  For some reason, perhaps because they were scientists and they objected to their ox being gored, Gross and Levitt were willing to subject themselves to the incredible boredom of attending the conferences, following the journals, and reading the books emanating from these various swamps.  Since they happened to be on the left of the ideological spectrum themselves, their book was also thoughtfully written and not just one of the usual rants from the right.

    Unfortunately, no one with similar insight and tolerance for pain has published anything of similar stature in the ensuing years.  We have been reduced to scrutinizing the data points that periodically bubble up through the froth to formulate some idea of how close we are to being saved.  Based on the meager information at our disposal, we gather that no great new secular religion has sprung up in the meantime to take the place of Marxism.  The only thing on hand to fill the vacuum left behind by its demise has been radical Islam.  Since, in a sense, it’s the only game in town, we’ve been treated to the amusing spectacle of watching leftist “progressives” making eyes at the fanatical zealots of one of the most reactionary religious systems ever concocted by the mind of man, while the latter have been busily cannibalizing the revolutionary vernacular familiar from the heyday of Communism.

    Other than that, it would seem that the scene today would be quite familiar to readers of Higher Superstition.  Consider, for example, the recent “revolutionary action” that took place on the campus of Swarthmore.  If we are to believe the somewhat overwrought account at National Review Online, it involved intimidation of the school administration and bullying of conservative students at what was advertised as an open Board of Managers meeting.  The ostensible goal of the disruption was to get the administration to agree to the divestment of stocks in fossil fuel companies, apparently based on the rather dubious assumption that nothing disagreeable would happen if all mankind suddenly stopped using them.  However, the divestment thing is hardly what is nearest and dearest to the hearts of the “academic left” at Swarthmore.  What is nearest and dearest?  According to NRO,

    The radicals are demanding a massive expansion of Swarthmore’s politicized “studies” programs, with a new Latino Studies major specifically dedicated to Latinos in the United States, and mandatory classes for all Swarthmore students in ethnic studies and gender and sexuality studies.

    I doubt that the gentry at NRO really understand what is going on here, because they lack the proper grounding in Marxist theory.  As Trotsky might have put it, they just don’t understand the dialectic.  What we are really seeing here is the emergence of a new exploiting class of gigantic proportions, cleverly attempting to obfuscate their true historical role behind a smokescreen of revolutionary jargon.  These people are exploiters, not exploitees.  Ensconced in their ivory towers, untouchable within their tenured cocoons, they are increasingly gaining a monopoly of the social means of education.  Like the bourgeoisie of old, who used the social means of production to suck the blood of the exploited workers, they use their own monopoly to feast on the sweat of the academic proletariat – their students.  They accumulate these useless “studies” courses for the same reasons that the capitalists accumulated money.

    Little realizing that they are being reduced to debt-serfs, with lives sold out and mortgaged to maintain these academic vampires in their accustomed luxury, the student proletariat are kept docile with fairy tales about “saving the world.”  Now, if Marx was right (and how could he possibly be wrong?) this “thesis” of the academic exploiters will soon run head on into the “antithesis” of the developing revolutionary consciousness of the student proletariat they have so cynically betrayed.  At least the bourgeoisie used their monopoly to produce something useful.  The new class of academic exploiters fobs off its victims with “studies” that they will find entirely useless in their struggle against the slavery that awaits them, unless they are among the happy few co-opted into the exploiting class.  Where is this leading?  How will the exploited academic proletariat react when they finally figure out, crushed under a mountain of debt, with heads full of “liberating” jargon and no prospect of employment that the “radical and emancipatory” blather they were being fed really leads to chains and slavery?  I can but quote the ringing warning of Edwin Markham in his famous poem, Man with the Hoe:

    O masters, lords and rulers in all lands,
    How will the Future reckon with this Man?
    How answer his brute question in that hour
    When whirlwinds of rebellion shake the world?

    The pundits at NRO should relax.  If I’ve interpreted the Marxist dialectic correctly, the revolutionary climax will be followed by a brief period of the dictatorship of the academic proletariat, followed by the gradual withering of academic administrations, and a new era of universal wisdom based on enlightened self-education.

    And what of the academic exploiters?  I think it goes without saying that it will be necessary to “expropriate the expropriators.”  However, being by nature a kindly and sedate man, I can only hope that it doesn’t come to the “liquidation of the academic exploiters as a class.”  On the other hand, I don’t want to be accused of “right opportunism” and realize full well that “you have to break some eggs to make an omelet.”

  • German “Greens” and the Poisoning of Eastern Europe

    Posted on April 22nd, 2013 Helian No comments

    A while back in an online discussion with a German “Green,” I pointed out that, if Germany shut down its nuclear plants, coal plants would have to remain in operation to take up the slack.  He was stunned that I could be so obtuse.  Didn’t I realize that the lost nuclear capacity would all be replaced by benign “green” energy technology?  Well, it turns out things didn’t quite work out that way.  In fact, the lost generating capacity is being replaced by – coal.

    Germany is building new coal-fired power plants hand over fist, with 26 of them planned for the immediate future.  According to Der Spiegel, the German news magazine that never misses a trick when it comes to bashing nuclear, that’s a feature, not a bug.  A recent triumphant headline reads, “Export Boom:  German Coal Electricity Floods Europe.”  Expect more of the same from the home of Europe’s most pious environmentalists.  Germany has also been rapidly expanding its solar and wind capacity recently thanks to heavy state subsidies, but the wind doesn’t always blow and the sun doesn’t always shine, especially in Germany.  Coal plants are required to fill in the gaps – lots of them.  Of course, it would be unprofitable to let them sit idle when wind and solar are available, so they are kept going full blast.  When the power isn’t needed in Germany, it is sold abroad, serving as a useful prop to Germany’s export fueled economy.

    Remember the grotesque self-righteousness of Der Spiegel and the German “Greens” during the Kyoto Treaty debates at the end of the Clinton administration?  Complying with the Kyoto provisions cost the Germans nothing.  They had just shut down the heavily polluting and grossly unprofitable industries in the former East Germany, had brought large numbers of new gas-fired plants on line thanks to increasing gas supplies from the North Sea fields, and had topped it off with a lame economy in the 90’s compared to the booming U.S.  Their greenhouse gas emissions had dropped accordingly.  Achieving similar reductions in the U.S. wouldn’t have been a similar “freebie.”  It would have cost tens of thousands of jobs.  The German “Greens” didn’t have the slightest problem with this.  They weren’t interested in achieving a fair agreement that would benefit all.  They were only interested in striking pious poses.

    Well, guess what?  Times have changed.  Last year U.S. carbon emissions were at their lowest level since 1994, and down 3.7% from 2011.  Our emissions are down 7.7% since 2006, the largest drop among major industrial states on the planet.  German emissions were up at least 1.5% last year, and probably more like 2%.  Mention this to a German “Green,” and he’s likely to mumble something about Germany still being within the Kyoto limits.  That’s quite true.  Germany is still riding the shutdown of what news magazine Focus calls “dilapidated, filthy, communist East German industry after the fall of the Berlin Wall,” to maintain the facade of environmental “purity.”

    That’s small comfort to her eastern European neighbors.  Downwind from Germany’s coal-fired plants, their “benefit” from her “green” policies is acid rain, nitrous oxide laced smog, deadly particulates that kill and sicken thousands and, last but not least, a rich harvest of radioactive fallout.  That’s right, Germany didn’t decrease the radioactive hazard to her neighbors by shutting down her nuclear plants.  She vastly increased it.  Coal contains several parts per million each of radioactive uranium and thorium.  These elements are harmless enough – if kept outside the body.  The energetic alpha particles they emit are easily stopped by a normal layer of skin.  When that happens, they dump the energy they carry in a very short distance, but, since skin is dead, it doesn’t matter.  It’s an entirely different matter when they dump those several million electron volts of energy into a living cell – such as a lung cell.  Among other things, that can easily derange the reproductive equipment of the cell, causing cancer.  How can they reach the lungs?  Very easily if the uranium and thorium that emit them are carried in the ash from a coal-fired plant.  A typical coal-fired plant releases about 5 tons of uranium and 12 tons of thorium every year.  The German “Greens” have no problem with this, even though they’re constantly bitching about the relatively miniscule release of uranium from U.S. depleted uranium munitions.  Think scrubber technology helps?  Guess again!  The uranium and thorium are concentrated in the ash, whether it ends up in the air or not.  They can easily leach into surrounding cropland and water supplies.

    The last time there was an attempt to move radioactive waste to the Gorleben storage facility within Germany, the “Greens” could be found striking heroic poses as saviors of the environment all along the line, demonstrating, tearing up tracks, and setting police vehicles on fire.  Their “heroic” actions forced the shutdown of Germany’s nuclear plants.  The “gift” (German for “poison”) of their “heroic” actions to Germany’s neighbors came in the form of acid rain, smog, and airborne radiation.  By any reasonable standard, coal-fired plants are vastly more dangerous and damaging to the environment than the nuclear facilities they replaced.

    It doesn’t matter to Germany’s “Greens.”  The acid rain, the radiation, the danger of global warming they always pretend to be so concerned about?  It doesn’t matter.  For them, as for the vast majority of other environmental zealots worldwide, the pose is everything.  The reality is nothing.


  • More on “Where have all the Babies Gone?”

    Posted on February 25th, 2013 Helian 1 comment

    Apropos the baby bust discussed in my last post, an interesting article on the subject by Joel Kotkin and Harry Siegel recently turned up at The Daily Beast via Newsweek entitled, “Where have all the Babies Gone?”  According to the authors, “More and more Americans are childless by choice.  But what makes sense for the individual may spell disaster for the country as a whole.”  Their forebodings of doom are based on a subset of the reasons cited in Jonathan Last’s “What to Expect when No One’s Expecting,” and are the same as those that usually turn up in similar articles.  The lack of babies, “….is likely to propel us into a spiral of soaring entitlement costs and diminished economic vigor, and create a culture marked by hyperindividualism and dependence on the state as the family unit erodes.”  As I pointed out in my earlier post on the subject, if all these things really will result absent a constantly increasing population, they are not avoidable outcomes, for the simple reason that, at some point, the population of the planet must stop growing.  The only question is, how many people will be around to experience those outcomes when they happen, and what fraction of the planet’s depleted resources will still be around at the time to deal with the situation.  Many of the commenters on the article do an excellent job of pointing that out.  For example, from Si 1979,

    At some point the population has to stop growing, space on the earth is finite.  As such there is going to come a generation that needs to ‘take the hit’ and the earlier that hit is taken the easier it will be.  The larger the population gets the worse an ageing population each generation will experience.  We can take the hit now or leave future generations a much worse problem to deal with.

    To deal with the “problem,” the authors propose some of the usual “solutions”;

    These include such things as reforming the tax code to encourage marriage and children; allowing continued single-family home construction on the urban periphery and renovation of more child-friendly and moderate-density urban neighborhoods; creating extended-leave policies that encourage fathers to take more time with family, as has been modestly successfully in Scandinavia; and other actions to make having children as economically viable, and pleasant, as possible. Men, in particular, will also have to embrace a greater role in sharing child-related chores with women who, increasingly, have careers and interests of their own.

    As a father of children who has strongly encouraged his own children to have children as well, I am fully in favor of all such measures, as long as they remain ineffective.

    The baby promoters have remarkably short historical memories.  Are they unaware of the other side of this coin?  One need go no further back than the 20th century.  What spawned Hitler’s grandiose dreams of “Lebensraum in the east” for Germany, at the expense of Russia?  Hint:  It wasn’t a declining German population.  Why did the Japanese come up with the “Greater East Asian Co-prosperity Sphere” idea and start invading their neighbors?  It happened at a time when her population was expanding at a rapid pace, and was, by the way, only about half of what it is now.  In spite of that, in the days before miracle strains of rice and other grains, it seemed impossible that she would be able to continue to feed her population.  Have we really put such fears of famine behind us for all times?  Such a claim must be based on the reckless assumption that the planet will never again suffer any serious disruptions in food production.  These are hardly isolated examples.  A book by Henry Cox entitled The Problem of Population, which appeared in 1923 and is still available on Amazon, cites numerous other examples.

    Needless to say, I don’t share the fears of the Kotkins and Siegels of the world.  My fear is that we will take foolhardy risks with the health of our planet by spawning unsustainably large populations in the name of maintaining entitlements which mankind has somehow incomprehensibly managed to live without for tens of thousands of years.  In truth, we live in wonderful times.  I and those genetically close to me can procreate without limit on a planet where the population may soon begin to decline to within sustainable limits because increasing numbers of people have decided not to have children.  It’s a win-win.  I’m happy with their choice, and presumably, they’re happy with mine, assuming they want to have some remnant of a working population available to exploit (or at least try to) once they’ve retired.  My only hope is that people like Kotkin and Siegel don’t succeed in rocking the boat.
