Becoming Planetary Gardeners: Geoengineering

8 Comments

The Earth’s climate is a complex web of systems: ocean temperature and current, sea and glacier ice, air, wind, sun, and more. Strands of that web are being plucked by the variety of things which are causing our climate to change: pollution, extra carbon dioxide, soot, cow farts, and maybe even sunspots. Superpower countries are vying for control of the Northern Passage and energy moguls are making record profits while doing serious damage. We’re letting them do it; it’s convenient to drive and shop and waste and live the lives we were taught we’d have. Me, too. Just as guilty as the next person. Heck, I ordered an ipad the first day I could. I, too, want the newest stuff.

One way out? Undo the damage and apply the principles of engineering to the systems that run the earth. Continue reading Becoming Planetary Gardeners: Geoengineering →

Self-assembling silicon circuits

Photolithography is running up against its limitations, as logic circuits become so small that the wavelength of light itself is too large to mask the patterns accurately. MIT boffins reckon they have a solution, though: self-assembling semiconductor circuits [via NextBigFuture].

Berggren and Ross’ approach is to use electron-beam lithography sparingly, to create patterns of tiny posts on a silicon chip. They then deposit specially designed polymers — molecules in which smaller, repeating molecular units are linked into long chains — on the chip. The polymers spontaneously hitch up to the posts and arrange themselves into useful patterns.

The trick is that the polymers are “copolymers,” meaning they’re made of two different types of polymer. Berggren compares a copolymer molecule to the characters played by Robert De Niro and Charles Grodin in the movie Midnight Run, a bounty hunter and a white-collar criminal who are handcuffed together but can’t stand each other. Ross prefers a homelier analogy: “You can think of it like a piece of spaghetti joined to a piece of tagliatelle,” she says. “These two chains don’t like to mix. So given the choice, all the spaghetti ends would go here, and all the tagliatelle ends would go there, but they can’t, because they’re joined together.” In their attempts to segregate themselves, the different types of polymer chain arrange themselves into predictable patterns.

Clever stuff, though still very much in the developmental stages. Maybe another new lease of life for Moore’s Law?

Tiny biodiagnostics lab on a piece of paper

So, let’s say the zombie plague is sweeping a nation where medical hardware is expensive, hard-to-come by, and hard to maintain. You need a way of testing the population for signs of contagion that’s cheap, portable, fast, and requires no power or mealthcare infrastructure. So what do you do?

You get them to lick the edge of a bit of paper about the size of a postage stamp.

(Non-apocalyptic deployments of this technology are also available. Terms, conditions and patents may apply in some legal theatres; please consult your biosolicitor.)

Lo-fi wi-fi network springing up from junk in Jalalabad

Jalalabad FabLab wi-fi reflectorOffered here as an extension of the arguments made by the Prospect Magazine piece I linked to the other week about the lessons to be learned from the last-minute low-cost solutions of slum residents and other disadvantaged social groups, Free Range International hosts a report from an MIT team working in Jalalabad, Afghanistan that describes how an injection of knowledge and expertise can accelerate local progress far more effectively than an injection of externally-managed aid money:

… the irony of the graphic above is particularly acute when one considers that an 18-month World Bank funded infrastructure project to bring internet connectivity to Afghanistan began more than SEVEN YEARS ago and only made its first international link this June. That project, despite hundreds of millions of dollars in funding, is still far from being complete while FabLabbers are building useful infrastructure for pennies on the dollar out of their garbage.

People are smart, adaptable; show them where they need to go, and they’ll find a way. What’s that old saw about giving a man a fish and feeding him for a day?

The post goes on to highlight the patient and painstaking work of showing the Afghanis that they need to work together to overcome their differences; a carrot and stick operation it may well be, but I’m guessing it’ll do more good than training up and arming local militias, and then expecting them not to fall back into old habits once your back is turned. All depends on whether you want to give these people their freedom or to take control of it yourself, I guess.

POD = DOA?

Via Chairman Bruce, a piece at The Economist about the rise of print-on-demand publishing:

Despite all its advantages, POD is unlikely to take over the world. This is because in contrast to digital printing, whose per-unit costs stay pretty much the same, traditional offset printing exhibits strong economies of scale. As long as you have bestsellers with hundreds of thousands of copies, on-demand printing is not going to displace the conventional sort, says David Davis of InterQuest. Then there is regulation. In some countries, such as China, a licence is needed to publish books; others, such as Germany and France, have price controls for books.

All this makes it difficult to predict POD’s impact on publishing’s supply chain, which is already in upheaval, mainly because of the internet. Readers should benefit from the greater variety. More authors will get published, for instance, but there will also be more competition. Publishers may save money, but they may also lose their role as gatekeepers. The losers are easier to determine: used-book sellers, logistics firms and, of course, the makers of offset-printing equipment. […].

Some believe POD could spur demand for books. Dane Neller, the boss of On Demand Books, which makes the Espresso, wants to put one wherever people might feel the urge to read, from cruise ships to train stations. But he gets most excited when talking about taking the devices to poor countries. “The potential to democratise knowledge,” he says, “is huge.”

I’ll leave the incisive commentary to Bruce Sterling, as he’s umpteen times better at it than I am:

Who really NEEDS print-on-demand books? Guys outside the distribution chain. And where do THEY live, one wonders. Oh wait, look. Here at the Bottom of the Pyramid. Those young guys with the cellphones. About a billion of ‘em.

I think it’s interesting to consider the potential effects of POD technology on a niche market like science fiction (or queer lit, or Lovecraftian retrohorror, or [insert small-volume-yet-international-and-surprisingly-tenacious literary scene here]), though, because it’s easier for a scene of that size to pick up and take over the gatekeeper mechanisms that POD would corrode.Whether they’d do as good a job is, of course, a matter for lively and passionate debate… 🙂

However, the caveat here is that I don’t understand the publishing business as an insider, and that we could probably all do with reading Charlie Stross’s ongoing Common Misconceptions about Publishing series (assuming you haven’t already, natch – I need to scrape together an hour or two to sit down and take notes while going through ’em in detail).

That said, I’m not sure that inside knowledge can effectively counter the suggestion that external technological and/or economic forces might completely up-end an entire industry, and render it unrecognisable (or at least unprofitable) in short order. If you’ve got informed input (or a good question!) please pipe up below and share it with us. 🙂
