- Christian high school discussion of climate change – Kurt Klein's AP Environmental Science class is reading Richard B. Alley's Two Mile Time Machine, about paleoclimate, ice cores, and abrupt climate change events. (tagged: climate ice science greenland education religion )
- Prefabricated Passive Houses in the USA – Bau Technologies is attempting to bring pre-fabricated (or rather off-site constructed) passive houses to the US. Looks awesome. (tagged: architecture sustainability energy efficiency passivhaus design )
- Yogurt making tips – Detailed instructions on how to make yogurt, and also a source for equipment and cultures. (tagged: food yogurt homemade cooking recipe )
- Climate Wars – A Canadian radio show exploring some of the climate change scenarios which have been studied by the US Dept. of Defense in a personal, "War of the Worlds" kind of way. Be forewarned, this is apocalypse porn, and probably not productive unless you need to get yourself riled up. (tagged: politics climate sustainability future war )
- Our Passive House — the first passive house in Utah. – A Utah couple chronicles the design and construction of their passive house, with blog posts and photos. Great to see these things going up on this side of the Atlantic finally! (tagged: passivhaus sustainability design architecture buildings )
- Will Allen: Street Farmer – A long profile of Will Allen and his intensive urban farming project in Milwaukee: "Growing Power". Aquaponics and vermicomposting of donated food wastes. This is realistic urban farming at a moderate scale. (tagged: sustainability urban food agriculture compost )
- Gini coefficient | Wikipedia – A wonderfully simple and general mathematical measure of the non-uniformity of a distribution, mostly used in economics, but applicable elsewhere just as well. (tagged: economics math wikipedia research science finance )
- Here comes the data: OECD Factbook eXplorer – There are terabytes of interesting data out there that nobody can actually understand, because we don't have good interfaces for playing with it, and poking around. This is the OECD's attempt to offer a window into its own demographic treasure trove. Obviously inspired by the gapminder, from Google and Hans Rosling. (tagged: data maps statistics visualization demographics oecd economics )
- The Choice of Cities – I'm not convinced we really know why the humans are coming to the cities. Whether it's a pull, or a push. How the migrants feel about their lot. Is it, globally, the same as the push we had in this country a hundred years ago? Or was it a pull? What happened when the frontier closed, when all the land was spoken for, and the factories and mines and mills were opened for business.
And what will cities look like once everyone has arrived? If we actually reach that day, when the countryside is emptied, and the flow staunched, then how will cities develop going forward? What will their margins look like? Will the slums filled with newcomers vanish? What will they be replaced with? (tagged: technologie urban design economics history technology poverty )
- Bike Among the Ruins – Detroit is half abandoned. The houses are almost free. The streets are empty and the people are poor. It's also flat. Could a cyclone of bicycles wipe clean the slate, even within the sight of our beloved, bankrupted, and now employee owned husk of an industrial titan… GM? (tagged: bicycle transportation urban design economy )
- Behind the Veil by Eve Arnold – A series of photographs of women, from Afghanistan and the middle east from 1969. Very different from our "Summer of Love"… (tagged: photos islam afghanistan women )
- The Revolution Will Not Be Digitized – Iran is one of the first places we get to see old school blood in the streets mixed with the new age of instantaneous, ubiquitous communication. We've tended to focus on the positive aspects, while briefly forgetting the potential powers of an electronic police state, which is to some degree what Iran has built. No massive army of eavesdroppers and informants is needed in such a regime. A few deep packet inspection boxes from Siemens sitting on the fiber backbone, and a few on the microwave towers from Nokia. Technology is largely neutral. (tagged: technology politics internet privacy government twitter web2.0 iran )
- 55 km to Amsterdam – A day of inter-city transportation by bicycle in the Netherlands. Can it really be that idyllic? (tagged: bicycle transportation netherlands infrastructure )
- 1993 Y Hike Pictures – Wow, pictures of myself from 1993 on the Y Hike. I still remember just about everyone in that group. I look so… young! (tagged: caltech yhike backpacking wilderness sierras )
- Traitor Joe's | Greenpeace – Trader Joe's doesn't make any effort to source sustainably caught fish. Unfortunately, with 70-80% of global commercial fisheries in collapse, it's virtually impossible to sell (or buy) most tasty fish species ethically. (tagged: sustainability fish traderjoes ocean food )
- Organic Farms as Subdivision Amenities – Housing developments that incorporate small organic farms, CSAs even, instead of the usual golf-course crap. How would one adapt this for denser living I wonder? (tagged: design agriculture urban csa food architecture )
- Enphase Energy System Monitoring – Another real-time and historical solar power monitoring system. This one is installed on the roof of one of the Boulder Housing Coalition Co-ops in Boulder. Pretty awesome! Smart grid indeed. (tagged: solar energy technology transparency electricity )
- Caltech Building Dashboard – A near real time view of the power being generated by Caltech's 200 kW PV installation on the Holliston parking structure. Also shows historical data and weather information. Pretty cool. Would be great to just have the raw datastream available via an API too… and be able to see all the Caltech's per-building consumption too. (tagged: energy solar caltech pasadena technology transparency data internet )
- How To Destroy Half the Planet for the Low, Low Price of 5% of Global GDP – Never mind the possibility of unforseen climatic consequences. Even if the pessimistic IPCC scenarios are right, and even if they "only" reduce global GDP by 5% over the next 100 years, that purely economic metric is not sufficient, because it turns out you can wipe 2.5 billion people and their nations off the face of the Earth, mainly in the tropics, and only reduce global GDP by 5%. Cold comfort, that. (tagged: climate economics gdp )
- Walter Mebane's statistical analysis of Iran's election results – Walter Mebane at UW Madison has done several statistical analyses of the Iranian election results, and finds significant irregularities in the Ahmedinejad results. (tagged: election iran statistics democracy fraud system:filetype:pdf system:media:document )
- Carbon Cap and Trade Debate – Ralph Cavanagh (legislative council for NRDC) and Jim Lazar, an economist, debate the merits of Cap and Trade, for an hour and a half. Looks interesting, but don't have time to watch it at the moment (tagged: video towatch climate policy economics )
- Property Assessed Clean Energy Bonds – PACE bonds are a way of overcoming the capital intensivity of many energy efficiency retrofits which make sense in the mid to long-term, but not on the typical short term investors time horizon. They also allow homeowners who may move before their investment in efficiency has paid for itself to pass on the obligation to future owners, instead of losing the investment. They also shift the costs of doing energy efficiency from capital expenses to debt servicing, which is advantageous in many jurisdictions for tax purposes. Berkeley, CA and Boulder, CO pioneered them for municipalities, but they can also work in a commercial context. (tagged: energy efficiency sustainability finance green debt investing bonds )
- It’s Now Legal to Catch a Raindrop in Colorado – Colorado has taken its first tentative steps down the road to legalizing… rainwater harvesting. I hope they go all the way. I'd hate to have to end up breaking yet another immoral law. (tagged: environment colorado water law sustainability rain green architecture design )
- Welcome to Tällberg – A "conference" analogous to the WEF in Davos, but held in Sweden, in the woods, and with sustainability as the given goal, instead of economic growth. Would be an interesting stop on the Green Cities Bike Tour. (tagged: green economics technology politics policy design conference )
- Power Struggle – A commentary on Steven Chu's position that we need major basic scientific and technological breakthroughs to successfully tackle our energy problems in the context of global warming. The hope is that in the short term, the vast array of incremental changes we have available is enough to get us started, and that by mid-century, the major breakthroughs will have been forthcoming. Ah, non-linear dynamics. (tagged: technology science energy climate non-linear sustainability policy )
- The Great American Bubble Machine – An article from Rolling Stone, by Matt Taibbi, on the endless bubble building shenanigans that Goldman Sachs has engaged in over the years, and their supposed current machinations to engineer a bubble in the as-of-yet uncreated market for greenhouse gas emissions. Markets, I like. Markets run by some Great American Gangster Kingpin, not so much. Especially not this particular market. Remember: Nature doesn't do bailouts. (tagged: economics finance goldmansachs capitalism climate bailout )
- The Economics of Ideas – An article about Paul Romer by Kevin Kelly, musing on the problems and benefits of having an economy which is primarily driven by informational goods. (tagged: economics technology non-linear )
- Paul Romer: A Theory of History, with an Application – Paul Romer talks about two different kinds of informational goods: "technology" and "rules". The former being knowledge about how to re-arrange the material world to increase its value to humans, and the latter being constraints on the ways we interact with each other. His "new/endogenous growth" theory suggests that overwhelmingly, wealth creation throughout history has been due to these two kinds of goods, and that they are virtually infinite resources. What he does not explicitly admit in the talk though, is that much of our increased apparent wealth has come at the cost of virtual liquidation of material resources. Truly sustainable growth absolutely must close the materials loop somehow. Better sooner than later. The rest of his idea is wonderful: we need a system which enables rule set entrepreneurs, or we aren't going to get sufficient innovation in the field. He suggests myriad autonomous city states, and I agree emphatically. (tagged: economics urban society non-linear politics longnow )
- The Swimming Cities of Serenissima – Improvised and chaotic houseboats built from found bits, floating down the Mississippi (2006-2007), or the Hudson (2008), or sailing the Adriatic from Slovenia to Venice (2009). Like a tiny maritime Burning Man. Only a couple of boats today… What if it were an armada? (tagged: art boat performance sailing )
- 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 )
- Do the British love their children too? – Two girls run over while biking to their school 3 miles away. British (and probably American) "solution": re-allocate a school bus to their area (removing the bus from somewhere else). Dutch/German/Danish solution: provide better cycling infrastructure for everyone. Guess which one I think is better. (tagged: bicycle transportation infrastructure accident bike )
- MIT open prototype initiative – A project to produce modular, open (freely available, non-proprietary) prototype designs for energy efficient buildings. MIT is so awesome. (tagged: green architecture design building )
- LEED Platinum Prefab Home Now Available – Taking all the design work out of building zero energy homes should make it a lot easier to build them, but the contractors doing the actual construction still need to understand what they're doing, and how their application of building techniques will affect the end performance of the building (and their profits need to be tied to that performance somehow) (tagged: green architecture leed construction buildings )
- Kidnapping Chrysler – Of course Cerberus (private equity firm that owns Chrysler, not three headed dog guarding hell) has a "fiduciary obligation" to seek a handout from the Feds. And by Jove, the Feds have a fiduciary obligation to refuse to give it to them! (tagged: bailout chrysler cerberus crisis economy gm )
- Where data goes when it dies – Following from the Ma.gnolia implosion, Chris Messina muses on data loss and recovery… kind of an information grieving process. What are we going to do with all of this information anyway? 100 years from now, all historians will have to be AI. (tagged: data archive backups loss microformats recovery )
- What really happened at Ma.gnolia – The social bookmarking service Ma.gnolia was, despite its surprisingly large user base, basically run like Ideotrope – one guy with a server, and some (in retrospect) pretty janky backups. A couple of weeks ago, the 500GB MySQL database file got corrupted, the backups failed, and the site imploded. Lessons to be learned indeed: number one is don't do your own IT, now that S3, EC2, the Google Apps Engine, and other such scalable enterprise systems are available. We gotta get that server retired… (tagged: backups magnolia data servers hosting )
- Baseline Scenario for 2009-02-09 – A rundown of the current global financial situation, and governmental attempts to get things under control. These guys aren't particularly optimistic at the moment about our ability to acknowledge just how beholden our supposedly powerful and developed governments have become to the banking industry. We're acting like Indonesia or Russia with their oligarchic overlords. (tagged: finance economy economics crisis )
- Thefts puncture Paris bike scheme – More of Paris' Velib bicycles are being stolen or vandalized than expected. Not sure what their expectations were, but it is pretty annoying for basically every bike in the network to have been either stolen or damaged in only 18 months. The vandalism is probably impossible to stop (since it can be carried out while the bikes are locked in their stands) but the theft should be preventable with secure stands, and aggressive enforcement of responsibility for a bike while you've got it checked out (i.e. if the bike doesn't come back, your credit card is immediately charged for the total value of the bike, or possibly even more). I also can't help but wonder if the same functionality could be implemented with much, much cheaper bikes, especially in a city as flat as Paris. Singlespeeds with fenders and a basket, maybe 100 Euros each? With an RFID tag embedded – and put all the smarts in the racks. (tagged: bicycle bike cycling transportation paris velib )
- Google Power to the People – Google developing tools to allow you to disentangle your own energy use, when the datastreams from smart meters come on line. Making this information easy to comprehend, pricing electricity to displace demand from the peak times, and allowing the largest energy users to schedule their use in an automated way could (without even changing anything physically) have a large impact on the amount of power generating capacity we (don't) need. (tagged: energy google sustainability green open data transparency )
- WattzOn and Wesabe Join Forces – This is the post that made me wish the Elevations Credit Union was more internet savvy. I want to be able to apply all these big-brotherly tools to myself! (tagged: open data transparency energy wesabe wattzon money finance )
- Numbrary – A library for numbers – mass quantities of publicly available data, mostly (entirely?) from the US Government. In a hopefully usable and searchable form. Many automatically generated charts and tables. (tagged: data transparency government statistics open )
- Mayapedal – People building useful human-powered bicimaquinas, in Guatemala, where human labor is still a common prime mover: washing machines, coffee de-pulpers, corn de-grainers, grain mills, blenders, concrete microvibrators, etc. One kind of appropriate technology. There's also some YouTube videos on them, e.g.:

- Humanity In Motion – An incredible montage of what bicycles can be: safe, enjoyable, cheap, convenient, everyday transportation for young people and for old, for families, in a city largely unpolluted by the exhaust and noise of cars. (tagged: bicycle transportation amsterdam netherlands photos )
