Wishful thinking about real estate and biofuel

I wrote a blog entry over at Klintron’s Brain that went from being a couple hundred words to basically a full length article:

Two economic crises face the world today: the credit crunch resulting from the subprime mortgage crisis, and the food prices crisis precipitated by the demand for biofuels. Both are problems we should have identified and solved years ago, but didn’t. Why did we ignore the warning signs and allow ourselves to be hoodwinked into this mess? I believe they both relate to our tendency for wishful thinking.

The Diesel Tree: Grow Your Own Oil

The Brazilian Copaifera langsdorfii, to use its botanical name, can be tapped not unlike a rubber tree, but instead of yielding rubbery latex it gives up a natural diesel. According to the nurseryman selling the trees, one hectare will yield about 12,000 litres annually.

Once filtered-no complex refining required, apparently-it can be placed straight into a diesel tractor or truck. We read that a single Copaifera langsdorfii will continue to produce fuel oil for an impressive 70 years, with the only negative being that its particular form of diesel needs to be used within three months of extraction.

Oddly this is not news. The Center for New Crops & Plant Products, at Purdue University reports that it was first reported to the western world as far back as 1625. They observe reports from 1979 saying “Natives … drill a 5 centimeter hole into the 1-meter thick trunk and put a bung into it. Every 6 months or so, they remove the bung and collect 15 to 20 liters of the hydrocarbon.’ The UN’s Food and Agriculture Organisation noted in a paper at the Eleventh world forestry congress back in 1997 on the topic of tree oil for cars that ‘… the potential of other alternatives such as the Amazon Copaifera langsdorfii need to be investigated.’

WorldChanging: do biofuels do more harm than good?

WorldChanging has a good round-up of anti-biofuel literature here. I looked into getting a biodiesel car last year but eventually decided that biodiesel wasn’t actually preferable to petroleum. Currently, I have no car and would prefer to keep it that way, but if I think if you must drive, it’s better to focus on getting a car with very good gas mileage rather than trying to get something that runs on biodiesel or ethanol.

Perhaps the most promising area of future biofuel development is algae for biofuel. Currently it costs too much, but if someone can figure out how to get the costs down (industrial production in giant vats?) it could work.

It was encouraging to see some open mindedness about nuclear energy from WorldChanging as well:

Sure, the mining, refining and shipping of uranium means that it’s not really a carbon-free technology. And sure, some nuclear plants are finding it hard to keep running, because the rivers they use to cool their reactors are getting too warm during the increasingly hotter summer months.

But at least these are problems we know about, whereas biofuels are suddenly looking like a jack-in-the-box of unpleasant surprises, ranging from higher food prices to ecosystem destruction to an actual worsening of the greenhouse gas emissions problem. I have been staunchly anti-nuclear for all of my adult life; but even I am beginning to scratch my head and wonder whether shutting down Sweden’s nuclear power plants — which the country originally committed to doing by 2010 — is such a good idea just now.

See what Stewart Brand had to say about nuclear here.

(For the record I’m highly skeptical about nuclear, but I do think it should be considered, especially as the risks involved are more and more mediated).

Desert Rock: Tribal Members Push Alternatives, Navajo Nation Wants EPA Action

“Navajo tribal members who believe their voices are needed in the fight against the proposed Desert Rock Power Plant their government supports claim a host of alternatives to burning coal exist on the Navajo Nation. The group, called Din? CARE, holds a viewpoint that is squarely opposite of Desert Rock supporters, such as project spokesman Frank Maisano, of the Washington, D.C., law firm Bracewell & Giuliani LLC.

“It’s a Navajo project and the Navajo are choosing to take part of their vast resources, which include coal, and advance the cause of their people,” Maisano said. “The plant will generate $50 million in revenue per year, bring thousands of construction jobs, 400 permanent jobs and a wealth of indirect benefits.” The massive project, however, is held up in the federal permitting process. Project developers hope to begin construction sometime this year near Burnham in San Juan County.

Din? CARE’s recent release of a report stating its views about the Desert Rock Power Plant project preceded by less than two weeks letters from Navajo President Joe Shirley, Jr. and the Bracewell & Giuliani firm notifying the Environmental Protection Agency of the tribe’s intent to sue to force EPA’s release of its Prevention of Significant Deterioration (air) permit. Desert Rock organizers submitted its air permit application to the EPA in May 2004. A draft permit was issued in August 2006, followed by a series of public meetings and hearings. EPA officials are still evaluating and responding to concerns from comments received at those meetings.”

Global warming and apocaphilia

Alexander Cockburn has recently published an article called “I am an intellectual blasphemer,” about the treatment he has received as a global warming doubter. Full Article: Spiked.

I’m not a scientist, much less a climate scientist. So as a concerned citizen it’s up to me to look to scientists and science journalists to form an educated opinion about human-centric global warming. My conclusion: it appears that the scientific consensus is that global warming is occurring and that it is at least partially caused by human activities. It also appears that global warming doubters have been defecting at a greater rate than global warming believers.

Scientific consensus has been wrong before, and will be wrong again. The case of Galileo is often brought up by those who wish to challenge the authority of the scientific community. And indeed scientific opinion can at times be as ridged as any religion. But history provides us with far more discredited cranks than vindicated Galileos. So if the fate of the planet is at stake, I’ll bet with the scientific community even if I’m rooting for the dark horse (really, it would be nice if there were no such thing as global warming).

But that isn’t really the point of Cockburn’s article. He seems mostly to be miffed at the treatment he’s received for having taken such a politically incorrect view. But how would Cockburn expect people to react if he suddenly took up the creationism, phrenology, radionics, or some other discredited theory? Would he really expect people to take his arguments seriously then?

This experience has given me an understanding of what it must have been like in darker periods to be accused of being a blasphemer; of the summary and unpleasant consequences that can bring. There is a witch-hunting element in climate catastrophism.

Yeah, I’m sure we’ll be seeing Cockburn burned at the stake any day now, along with all the conservative politicians and business people whose careers have been ruined by powerful church of global warming.

Cockburn does make some valid points about modern environmentalists:

The left has bought into environmental catastrophism because it thinks that if it can persuade the world that there is indeed a catastrophe, then somehow the emergency response will lead to positive developments in terms of social and environmental justice.

This is a fantasy. In truth, environmental catastrophism will, in fact it already has, play into the hands of sinister-as-always corporate interests. The nuclear industry is benefiting immeasurably from the current catastrophism. Last year, for example, the American nuclear regulatory commission speeded up its process of licensing; there is an imminent wave of nuclear plant building. Many in the nuclear industry see in the story about CO2 causing climate change an opportunity to recover from the adverse publicity of Chernobyl.

Indeed. And even on the side of the environmentalists are a number of unsavory political agendas – there’s no shortage of sociopathic cryptofascists in the environmental movement (particularly in the “green anarchism” movement). People who believe that the very existence of humans is an unspeakable injustice, and that we must all suffer for it. Misanthropes who are convinced that mass human extinction would be a good thing. People who believe that it’s worth bombing innocent people to stop technological progress.

Cockburn goes on to equate global warming fears with religious apocalyptic views, which Trevor Blake expands upon:

I have a suggestion as to why large groups of people are supporting the athropogenic global warming theory, but it is one I read long ago by an author I sadly cannot remember and credit. Ask yourself where the largest environmental movements are, and where the most radical / violent environmentalists are. The answer is, roughly, the USA, Canada, England and Germany. All of these countries are, among other things, largely Protestant countries. Compare the environmental movement in these Protestant countries with the environmental movements in largely Catholic countries, such as Italy or Mexico. Compare it also with the environmental movements in Islamic countries. It seems that Christianity co-occurs with environmentalism more than with Islam, and more with Protestant Christianity than Catholicism. Protestant Christianity is heavy with stories of the original purity of humanity and our harmony with the Earth, but through our wickedness in taking on the powers of God we have brought about great suffering and destruction – including the any-day-now destruction of the entire Earth. Compare this to environmentalism, which is heavy with stories of the original purity of humanity and our harmony with the Earth, but through our wickedness in taking on the powers of God we have brought about great suffering and destruction – including the any-day-now destruction of the entire Earth. Environmentalism is in part an echo of Protestant Christianity, which was relegated to ceremonial reverence as the West adopted secular values.

It’s interesting to note the similarities between various apocaphiles. The narratives spun by economic collapse, peak oil, and global warming fear mongers, for example, sound a lot like stories of the rapture. A day of judgment will come, and those who took the righteous (those who bought vaults, stocked up on food, or prepared to live in Bronze Age conditions) will be rewarded and the wicked will be punished. It’s telling that the answer to our problems is always the same: buy the right stuff.

There will always be tyrants and hucksters trying to exploit fear and misfortune. This does not discredit the body of science that tells us what we must do in order to avert catastrophe. The most important thing we must do, ween ourselves from fossil fuels, is a generally positive thing in and of itself. Regardless of its global impact, air pollution caused by cars, power plants, factories, etc. is real. And the US’s addiction to oil has caused numerous geopolitical nightmares. We shouldn’t need global warming or peak oil to motivate us to make these changes. Nor should we allow fearmongors and hucksters to hoodwink us into adopting solutions that do not solve our problems, put an undue burden on the under privileged, or cause unnecessary loss of liberty.

What We Can Learn From The Lunatic Fringe?

perpetual motion machine

We’ve all heard claims of green inventions that are too good to be true: the zero-point energy generator, the water-powered car, the device for talking with dolphins to achieve world peace. Sometimes they amuse us; sometimes they confuse us, as we try to determine whether they’re legitimate or not; and sometimes they just annoy us. But can they ever help us? Yes: by keeping our imaginations open, and by honing our evaluation skills — skills which are useful both when deciding between existing technologies, and when thinking about technologies on the

Can’t Blame the Sun for Global Warming, Says Study

The best, IMHO, alternate explanation for global warming is looking a bit less likely:

“The upshot is that somewhere between 1985 and 1987 all the solar factors that could have affected climate have been going in the wrong direction. If they were really a big factor we would have cooling by now.”

Reason Magazine science editor Ronald Baily adds:

Of course in areas that are prey to big uncertainties, no study is definitive. However, as the evidence for man-made global warming continues to accumulate, policymakers and citizens should turn our attention to what should be done about it. See some of my thoughts on the carbon taxes vs. carbon markets here.

Disclosure: Just in case any H&R readers missed it, I am a former skeptic of man-made global warming. See my mea culpa here.

A factory of one’s own

According to MIT’s Neil Gershenfeld, the digital revolution is over, and the good guys won. The next big change will be about manufacturing. Anyone with a PC will be able to build anything just by hitting ‘print.’

(Fortune Magazine) — Imagine a machine with the ability to manufacture anything. Now imagine that machine in your living room. What would you build first? Would you start a business? Would you ever buy anything retail again? According to MIT physicist Neil Gershenfeld, it’s not too early to think about these questions, because that machine, which he calls a personal fabricator, is not so far off – or so far-fetched – as you might think.

Gershenfeld is director of MIT’s Center for Bits and Atoms (CBA), an interdisciplinary outfit studying the intersection between information theory and industrial design. He also teaches a course called How to Make (Almost) Anything.

Five years ago the National Science Foundation awarded the CBA $14 million to build a manufacturing lab full of futuristic hardware. That includes a nanobeam writer that can etch microscopic patterns on metal, and a supersonic waterjet cutter that generates 60,000 pounds of water pressure, enough to shear through almost any material. The CBA factory can churn out anything, from the tiniest semiconductor to an entire building.

Bacteria provide horsepower for tiny motor

For millennia, people have hitched beasts to plows to exploit the animals’ strength and energy. In a modern variant of that practice, scientists have chemically harnessed bacteria to a micromotor so that they can make the device’s rotor slowly turn.
