A Concrete Fix to Global Warming (MIT Technology Review)
A company in Nova Scotia says it has developed a process by which manufacturers of precast concrete products can store 60Ts of CO2 in every 1000Ts of concrete product. This would be factory carbon dioxide (produced by heating the plant, running the machinery, etc.), which would be redirected onto the concrete, and absorbed (sequestered) by it, effectively negating the initial production of CO2. From the article: QUOTE: Concrete accounts for more than 5 percent of human-caused carbon-dioxide emissions annually, mostly because cement, the active ingredient in concrete, is made by baking limestone and clay powders under intense heat that is generally produced by the burning of fossil fuels. Making finished concrete products--by mixing cement with water, sand, and gravel--creates additional emissions because heat and steam are often used to accelerate the curing process. But Robert Niven, founder of Halifax-based Carbon Sense Solutions, says that his company's process would actually allow precast concrete to store carbon dioxide. The company takes advantage of a natural process; carbon dioxide is already reabsorbed in concrete products over hundreds of years from natural chemical reactions. Freshly mixed concrete is exposed to a stream of carbon-dioxide-rich flue gas, rapidly speeding up the reactions between the gas and the calcium-containing minerals in cement (which represents about 10 to 15 percent of the concrete's volume). The technology also virtually eliminates the need for heat or steam, saving energy and emissions. UNQUOTE One of the comments to the article notes that carbonated concrete wouldn't be good for use in reinforced concrete buildings because the carbonation reduces the alkalinity of the product, and that in turn affects the durability and strength of the rebar/ steel, but that it would work well for sidewalks (and presumably cinderblock type materials?). Interesting development, at any rate, as concrete production accounts for 5% of the world's human-caused carbon-dioxide emissions annually.

Computer says get a life – and we have | Simon Jenkins - Times Online
Simon Jenkins ponders the seeming paradox that while music cd/ record sales plummet and prices for individual recordings drop as well, live concerts sell out at premium prices. He ponders other, related phenomena, too -- readings by writers, lectures, live performances of any kind: all seem to get more attention (and MONEY) than the products themselves. He concludes and argues that people are willing to pay for what they want, and what they want is the real, authentic thing (i.e., person), not another technologically mediated simulacrum. Two things: one, if he's right, this has dire consequences for visual art, unless the visual arts want to devolved strictly into performance art; and two, for those of us who are terrified of public speaking/ public performances, this isn't comforting news. Some of us like the internet because it preserves our sanguinity (if that's a word).

A design-savvy city defined, by Knute Berger (Crosscut Seattle)
For future reference: Berger's article about a report by architectural firm RMJM, which identifies America's top 10 best-designed cities. His article focuses on the aspect of heritage preservation, which factors into RMJM's weighting and criteria, and he notes that Portland seems to beat out Seattle. From there, Berger segues into whether or not (or to what extent) citizens are "pleased with their urban architecture," and observes that only LA residents are "less happy with their city" than Seattlites. (I'm not sure how he manages the leap from heritage preservation to 'being pleased" by contemporary/new architecture, but there you have it.) Anyway, the really useful thing about this article is that Berger lists the 7 categories RMJM used to answer the question, "what makes a design-savvy city?", and also summarizes each aspect (with commentary of his own, in italics). All in all, the list makes a great framework for thinking about urban design.

The Bellows » How Good is Houston?
Ryan Avent of "The Bellows" critiques Ed Glaeser's piece for the New York Sun, which, according to The Bellows, is riddled with errors and is undermined by Glaeser's own research. Glaeser's neo-con thesis in the NY Sun article is that Houston is middle-class-friendlier and somehow more affordable due to its libertarian anti-regulationist stance, and that NYC is unaffordable because it's regulated to the nines. It's a very familiar argument in some circles, and it's interesting to see Ryan take it apart quite deftly.

architecture for hertzian space | varnelis.net
Fascinating essay by Kazys Varnelis, which takes as its jumping off point the potential discrepancy between designing for "hard" stuff (whether factories, industrial production, or ...architecture/buildings) vs. designing for networked stuff and software and mobile technologies. After this initial set-up, Varnelis then quickly goes into describing some very specific site- and urban-intervention type projects that subvert the "hard" aspects of planning & building via software/ new technologies. The former points are not that difficult to address, using predictable interventions and affordances (see my notes/ annotations), but the latter are mind-blowing and difficult to contain within predictability.

Crosscut Seattle - The founder of ArtsJournal talks about arts and new media
Much to think on in this great interview by James Bash with Douglas McLennan, the founder of ArtsJournal. "Curation" is definitely my word du jour -- I've seen it come up again and again recently, in relation to *very* different products and businesses (clothing & retail, for example). It leads me to think that "curation" is something that's evolving out of "filtering," which in turn was something that sort of / kind of evolved out of (or related to) "gatekeeping." The latter always struck me as something almost hateful, in the sense that gatekeepers protected the various walled gardens to which access was limited or even forbidden. Gatekeepers weren't there for me, they were there for "them." Filtering in turn proposed the notion that users (me, we) should set their own parameters -- it's potentially democratic, anyway, provided we don't let overlords filter for us. DIY filtering can be smart, letting us develop efficiencies in how we access and consume information. But filtering done by censors is bad. Curation can be equally two-edged (like filtering), but it now introduces another aspect: perhaps trust? Some sort of acknowledgement of expertise, or sophistication? Good curation, however, done on a digital platform, is open, accessible, democratic, and transparent. Perhaps curation is an open, acknowledged re-insertion of the human aspect -- which "filtering" can strive to eliminate via automatic settings and controls.

"Get set - the future starts now" by Christopher Hume (Toronto Star)
Well, don't say I didn't tell you so: QUOTE: "Politically," Miller continues, "cities in Canada don't exist, especially at the federal level. As far as I know, this is virtually unique in the world. Throughout the world, federal and national governments invest in cities, but we don't see that here. All cities in Canada are suffering from lack of federal spending." UNQUOTE This is so distressing, from where I'm sitting -- because Victoria has the additional burden of being one of 13 municipalities in an urban conglomeration (the CRD), and has the additional burden of being a "lefty" NDP hold-out in BC Liberal Party-land. It shouldn't BE this partisan, and yet it seems to be...

With Gas Over $4, Cities Explore Whether It's Smart to Be Dense - WSJ.com
Have had this article open in a browser tab for days now -- time to bookmark. Along with posts by CEOs for Cities, or Richard Florida, this article too points to the effect that gasoline prices are having on suburban housing, and on the "sudden" desirability of urban living. (Well, I say "sudden" because I've *NEVER* understood why anyone would want to live in suburbs instead of living in cities/ densely packed neighbourhoods where you just have to walk a block or two, or less, to find social activity...) From the article, QUOTE: "Expensive oil is going to transform the American culture as radically as cheap oil did," predicts David Mogavero, a Sacramento-based architect and smart-growth proponent. (...) Even though the area's housing market has been wracked by price drops of 25% in the last year and one of the highest foreclosure rates in the country, Mr. Friedman says he already has sold nine of 28 town houses near downtown that he recently completed, and three more are under contract, "which is not bad considering the dismal state of the Sacramento real-estate market." Mr. Morris, the developer, says the housing downturn is hurting the places that have the "dumbest growth. Smart growth works when the rest of it doesn't." UNQUOTE

Closing on Broadway - Two Traffic Lanes - NYTimes.com
Article about the "Broadway Boulevard" project, which will take some of current automobile lanes and turn them into public seating/ parks and bike paths. The project stresses the importance of wresting public space back from cars, for public/ pedestrian/ non-vehicular use. QUOTE: “Broadway is not famous because there are a gazillion cars going through it,” she said. “We’re trying to have the public space match the name.” UNQUOTE

Looming Debate, by Veronique Vienne (Metropolis Magazine)
Interesting article (with some inaccuracies, too), focused chiefly on Bertrand Delanoe, the "Situationist"-inspired left-leaning, assassination attempt survivor and openly gay mayor of Paris, who gets blind-sided by Nikolas Sarkozy, the pro-business president of France, who wants Paris to be a bit more get-go-ish. Delanoe is on the side of the human-scale advocates who want to preserve its "charms," whereas Sarkozy doesn't mind a tall building or two. The article is interesting because it's one of the clearest outlines I've seen so far on making political linkages between certain attitudes toward modernization and height in Paris, vs preservation (and rejuvenation) of what that city's status quo as well as historical "essence" (at least mid-19th century onward) is.

Architecture of Change - Sustainability and Humanity in the Built Environment (PingMag - The Tokyo-based magazine about “Design and Making Things”)
Ping Magazine interview with Berlin-based Kristin and Lukas Feireiss on their book, _Architecture of Change - sustainability and humanity in the built environment_, regarding the "conscious contradiction in the title — changing and sustaining. But how can I change and sustain at the same time? This challenge is what we try to put across." QUOTE: There’s more to architecture than its simple purpose of shelter or protection, a cast to architecture. However they are creating social environments, urban spaces and the public spaces where people actually interact. So they are the catalyst for social interaction, for society to work in. This is a big topic and we can go from dictatorial architecture to that of social engagement. (...) This book gives a broad overview of what’s possible in sustainable building practices or social practices in architecture. So it ranges fr
