  • Math and the City – The same scaling laws seem to apply to both cities and organisms: infrastructure requirements per capita (or per unit body mass) go down as population (size) go up. Not so surprising, since both cities and bodies are connected to themselves by networks of wires (neurons) and tubes (pipes, transportation, blood vessels) (tagged: urban design economics sustainability transportation infrastructure biology )
  • Sustainable Transport that Works: Lessons from Germany – A 60 page report on how Germany has transformed its urban transportation systems over the Post-War period, moving toward more public transit and bicycle infrastructure, the costs, benefits, effects, etc. What has worked, and what hasn't. (tagged: bicycle transportation policy urban design system:filetype:pdf system:media:document )
  • NASA Gets Out of Satellite Servicing Business – And good riddance. Yes, the capability was amazing, but expensive and unnecessary. For the price of *each* Hubble servicing missions, we could have launched an entirely new Hubble-class telescope on a rocket. The shuttle is a solution in search of a problem. Someday we'll have a real reason to send people into space — e.g. long term scientific exploration of Mars, or if we're lucky, the beginnings of a two-world civilization — but until then, we're just going around in circles, and forking over hundreds of billions unnecessarily to the aerospace industry. Better them than the banks… but that's really no argument to stand on. (tagged: space nasa politics policy )
  • Buying farmland abroad: Outsourcing's third wave – I don't know how anybody can think this is going to work long term. The whole point is to have food when there's a crisis, but in case of crisis, these deals are going to go down hard, unless those on the receiving end are willing to deploy their militaries on foreign soil to protect their investment. Which isn't impossible, but certainly doesn't seem like a great deal for anyone. (tagged: agriculture food china africa sustainability economics trade )
  • Crack Gardens – No, not gardens in which you grow crack, gardens growing out of cracks. A little creative jack-hammering opened up some fissures in this concrete slab, out of which a garden now grows. An homage to the tenacious plants that will take our cities apart when we leave.

  • Forecast: On Climate Change, Cooler Temperatures Bring Hotter Air – Augh, we are prisoners to so many perceptual fallacies. Recency and narration loom large among them. It turns out that the average temperature of the last 12 months is a reasonably strong predictor of whether or not people think they'll personally experience the effects of climate change (a multi-decade to century-scale process). We are failing to deal with problems we didn't evolve to perceive clearly. (tagged: climate statistics fallacy propaganda science )
  • In German Suburb, Life Goes On Without Cars – Ah, the New York Times has discovered Vauban! Now if only it had happened when gas was $4/gallon, we might have had a chance. We desperately need more experimentation in urban design, so we can have working examples to look at and build on. (tagged: sustainability green urban design bicycles germany transportation parking architecture )
  • Spuds in a Box – Build a box whose sides you can progressively remove from the bottom up, plant potatoes in the bottom, and fill with dirt as they grow. Remove lower slats to harvest spuds. I've certainly heard this suggestion from other people too. Will be interesting to see how well it works for these guys. Seems like you could also do this with some kind of bag, and if you sewed in sleeves/tubes periodically, that you could tie off, and then untie when you wanted to reach in and root around for a spud, you wouldn't have to worry about soil falling out when you pry off the boards. Others are supposedly reporting 50kg of potatoes from 0.5 m^2 area. (tagged: gardening green sustainability agriculture food urban design potatoes )
  • How Much Do You Earn? – A great annotated visualization of income distribution in the US as of the year 2000. It would be awesome to see an animated version of this, and see how it evolves through time. Turns out I make just about the most likely income in America ($20k), which is far below the mean (and the median). As a "household" though, I suppose we're right about at the median ($40k). Interesting. (tagged: economics wealth taxes government policy visualization )
  • The Capitalist Threat – Geoge Soros on Karl Popper's Open Society, from the mid-90s. He rails against the West's failure to extend a helping hand to the post-Soviet nations. He acknowledges that Truth may not be a strong enough motivator for most people, and that within a society that has decided to be Open, there are still many other choices to be made, but somehow fails to mention the way these two things end up pushing an Open Society closed with propaganda, apathy, and misinformation. Political evangelism – the process of deciding what (arbitrary) values your society is going to have – creates huge incentives for those who do not highly value truth to assert authority. I guess that's part of his point though, to robustly inoculate society against those assertions of perfect (authoritarian) knowledge. (tagged: economics politics popper society philosophy )

  • Where can you get Cheap Natural Fertilizers and Soil Amendments? – A nice concise list of natural sources for garden nutrients, when your compost pile just isn't quite enough. (tagged: gardening food organic fertlizer compost biology )
  • Pinko bastion spawns capitalist solution to solar financing – Boulder city/county passed the same kind of property-tax based financing of energy efficiency (and solar) improvements on the Nov. ballot too – modeled on Berkeley, but with enabling legislation at the state level (to avoid the kind of lawsuit Berkeley had to fight over whether or not they had the power to issue such bonds). The biggest worry I had in reading the Boulder initiative though, was that they had not yet come up with a good mechanism for ensuring that the improvements which were being proposed (more insulation, solar hot water, whatever) would necessarily save enough energy in order to justify the value of the bond being created. Hopefully they’ve fleshed that metric of value out much better by now (in both Boulder and Berkeley) and it’s not possible to abuse it… otherwise I suspect you’ll get deployment of faddish fixes (e.g. sexy-sexy PV instead of solar hot water, or better insulation, or super-windows, etc) instead of the best energy improvement per dollar invested.

  • Campaign for a Car-Free Lincoln Park, Pt. 2 – A lack of car-free options for arriving at Lincoln Park, coupled with poorly lit, unsafe parking far away from the park's main attraction means everyone just drives their cars all over the park, on the grass. Across the street, the DMV has a huge parking lot which is totally unused after business hours, which is when the park gets the overwhelming majority of its use. Why not (gasp!) timeshare the DMV lot? Hopefully no small children have to get crushed by the marauding death machines for someone in the state and city government to take this idea seriously.

  • FlyingConcrete – Beautiful biomimetic architecture. Curving vaulted ceilings and stairways. Rounded sleeping nooks and pillars like trees. Traditional rectilinear construction is so boring. This is lightweight concrete (cement with perlite, pumice, and other lightweight filler added instead of sand and gravel) laid up on a mesh that's been shaped such that when the cement hardens, it's a load bearing compressive structure. (tagged: architecture art concrete design construction buildings sculpture )
  • Drew Endy and Jim Thomas Debate Synthetic Biology – An unusually good discussion about the future of biotechnology, and maybe the only time I've ever really seen the "debate" format work, and elicit relatively thoughtful interaction. I think they're both dancing around the fundamental question though, of to what extent (if any) society even *gets* to make a choice on this topic.

  • How David Beats Goliath – When the rules are stacked against you, the intelligent thing to do is break them. (tagged: strategy law war insurgency guerilla gametheory basketball lawrenceofarabia )
  • Continuous bankruptcy – Bankruptcy as it stands now is a discontinuous process. Your legal solvency is binary: either you are bankrupt, or you are not. It doesn't have to be that way, and I think you can make a good argument that it's better if it isn't. Continuous processes work themselves out in small steps, with lots of information flow along the way. Discontinuous ones are like explosions. It's easier to muster resistance to an explosion once you see it coming, and delay it. But how much better to start getting signals early on, and avert it altogether? (tagged: finance policy economics bailout banks bankruptcy discrete continuous )
  • Digital Recovery of Moon Images – Ahh, NASA. Your data management has improved over the years, but that's not saying much. 20 tons of magnetic tape in an abandoned McDonalds houses the only extant copy of the pre-Apollo analog imaging of the Moon (still the highest resolution available in most places). It can only be read by one machine on Earth, which was recently rescued from a chicken coop, and refurbished by a man who is about to die. You can't make this stuff up. (tagged: information technology space nasa archive data moon )
  • Will the Future Be Geo-Engineered? – The future is already geo-engineered, and has been ever since we started burning coal on a large scale more than 200 years ago. The question now is whether we back off, and try to let the system return to the quasi-equilibrium that allowed our civilization to arise, or introduce new and exciting perturbations, with completely unpredictable non-linear effects. I know which one I'm hoping for. (tagged: geoengineering technology non-linear climate policy environment )
  • Hacking Scalia – Law professor gives class an assignment to dig up as much "private" info as possible on Justice Scalia, a notable anti-privacy force on the SCOTUS. This irritates Scalia. Exactly! (tagged: law privacy scalia scotus )
  • No new coal: what real direct action looks like – The $10 million spent on violently policing the "climate camp" protest outside Kingsnorth is absurd, given that a single motivated saboteur, capable of advance planning and actually willing to risk arrest and injury, can walk into the power plant and shut down 500MW of coal fired power generation. If governments fail to deal with greenhouse gas emissions effectively, and remain in thrall to the carbon lobbies, it seems likely that soon this kind of action will become more common, and truly disruptive. All it takes is a few thousand people who actually care, and our infrastructure can be brought to its knees. (tagged: energy environment green coal climate protest kingsnorth directaction )

  • Transparency means nothing without justice – Government transparency is necessary, but not sufficient. If police violence is recorded and publicized, and nobody cares, it doesn't matter. This is in come sense emblematic of the coup in western propaganda. You don't need to control the media as the Soviets did or the Chinese do, if your population is comfortable enough not to care what's happening out there to someone else, and if their voting patterns are firmly tied to other issues (especially social issues like abortion), the idea of a democratic revolt becomes fairly abstract. I think this where a lot of the government's fear of economic recessions comes from. When people are out of work, or even hungry, suddenly they become a lot more excitable.

  • Condensing steam without water – Concentrating solar thermal power stations are ultimately designed to run a steam turbine, just like a gas-fired power plant. That means they need water (to turn into steam). Problematically, most such plants use water as a condensing coolant (70% of Caltech's water usage is as coolant for our 14MW worth of gas-fired power)… which is going to be hard to come by in the desert, where CSP will be built. Thankfully, there's a way to recondense steam without using a water coolant – but it does require a huge cooling tower. Not so great in Pasadena, but probably fine in the Mojave, next to acres and acres of mirrors. (tagged: solar energy technology sustainability green electricity water )
  • Rousing a Latent Defense Mechanism to Fight HIV – It turns out there is a gene in humans that produces a protein which inhibits infection by HIV, but it has a mutation – a premature stop codon – which prevents it from being effectively synthesized. This mutation doesn't exist in most Old World monkeys (and that's apparently why they can't get HIV). Undoing the mutation allows the protein to be synthesized, and grants HIV immunity to human cells. I imagine that undoing bad mutations like this, and our inability to synthesize vitamin C, might be the first place we see human germ-line engineering outside of disease avoidance (preventing e.g. cystic fibrosis). Really, these mutations are hard to distinguish from genetic diseases – they're just diseases that we, as a species, have learned to live with.

  • Anna in the Middle East – Anna Baltzer is a Jewish American who got a Fulbright fellowship to live in the West Bank in 2005, and document the experiences of Palestinians. She's been giving presentations about it ever since. Some parts of her presentation are available via YouTube too. From the 15 minutes I watched she seemed like a level headed critic. She's speaking in Boulder and Denver in May. (tagged: israel palestine politics fulbright peace war )
  • Twitter + Stimulus = Humans are Gullible – A wonderful demonstration of the power of the confirmatory bias. Twitter is the perfect platform for the injection of random falsehoods. Too short for citations. Instantaneous distribution. Make sure your followers are predisposed to agree with what you say, and you can get them to believe just about anything – within that constraint. Too bad the author seems to think this only applies to conservatives. (tagged: politics twitter statistics propaganda )
