Horst Glaesker paints wind turbines. Not pictures of wind turbines, but entire 100m tall turbines in psychedelic colors that are more akin to dazzle camouflage than to art. Gotta admit, I’m pretty skeptical about ‘aero-art‘ actually being art (even when subscribing to the definition of art being whatever somebody calls art).
Maybe it’s just a case of cultural mistranslation of Glaesker’s Tutonic style. But these color schemes and geographic patterns won’t win any over any opponents to wind development. I would also hazard to guess that the paint job won’t prevent any bird strikes either.
Instead of fighting carbon emissions that threaten to undermine our economy, a group of scientists have looked at the benefits of curbing ozone precursors and black carbon.
National benefits of the CH4 plus BC measures versus the reference scenario. Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Surface temperature changes are from the GISS-E2-S simulation. Health, agriculture, and atmospheric forcing impacts are based on the average of GISS and ECHAM concentration changes and are for 2030 and beyond. Uncertainties are ~60% for global mean temperatures, with national scale uncertainties likely greater, ~60% for atmospheric forcing, ~70% for health, and roughly –70%/+100% for crops [see (7) for factors included in uncertainties, most of which are systematic for atmospheric forcing, health, and agriculture so that much smaller differences between regions are still significant]. Interactive versions providing values for each country are at www.giss.nasa.gov/staff/dshindell/Sci2012, whereas alternate presentations of these data are in fig. S5 and table S5.
The benefits of controlling methane and soot emissions turned out to be considerable. Largely thanks to reduced methane emissions, global warming by 2050 would be reduced by about half a degree; global warming so far has amounted to about 0.8°C. The additional controls also ensure that the low-carbon scenario holds warming below the danger level of 2°C of warming, at least for the next 60 years. Methane controls would also keep ozone low enough to avoid annual crop losses of 30 million to 135 million metric tons in 2030
The drop in outdoor air pollution, due largely to soot emission reductions, would avoid 700,000 to 4.7 million premature deaths each year. Indoors, more than one-third of a million lives would be saved annually in India and China alone. A total of at least a million lives saved a year compares with the 600,000 premature deaths from tuberculosis expected in 2030 or the 2.1 million deaths due to traffic accidents. – from Richard A.

Playgrounds have lost a sense of imagination since the lawyers got involved, resulting in boredom and lack of use (plus their style can be best described as a pastiche mixed together by a committee). There is a burgeoning renaissance of high-design returning to playgrounds (such as recent parks by Van Valkenburg in NYC or the ‘Rollercoaster Walkway’ in Germany – though these seem more for adults than kids).
Jungle Gyms date back to 1923 and were a feature of progressive k-12 education. Now most risky play activities has been regulated out of existence for younger children – so there is a documented loss of self-assurance and an increased fear of heights. Risky play is essential for development per Dr. Sandseter:
- exploring heights,
- experiencing high speed,
- handling dangerous tools,
- being near dangerous elements (like water or fire),
- rough-and-tumble play (like wrestling), and
- wandering alone away from adult supervision.
“Climbing equipment needs to be high enough, or else it will be too boring in the long run,” Dr. Sandseter said. “Children approach thrills and risks in a progressive manner, and very few children would try to climb to the highest point for the first time they climb. The best thing is to let children encounter these challenges from an early age, and they will then progressively learn to master them through their play over the years.”
… “There is no clear evidence that playground safety measures have lowered the average risk on playgrounds,” said David Ball, a professor of risk management at Middlesex University in London. He noted that the risk of some injuries, like long fractures of the arm, actually increased after the introduction of softer surfaces on playgrounds in Britain and Australia.
“This sounds counterintuitive, but it shouldn’t, because it is a common phenomenon,” Dr. Ball said. “If children and parents believe they are in an environment which is safer than it actually is, they will take more risks. An argument against softer surfacing is that children think it is safe, but because they don’t understand its properties, they overrate its performance.” – nytimes
As the father of a 3 1/2 y.o., I wish he could experience the playgrounds of the ’70s that formed the core of my childhood. I’m willing to trade a few bumps, bruises, and perhaps a broken bone or two to help build his character and physical development – especially since most of these play structures required imagination to use. The rest of this post is a few of the cool play structures worthy of celebration and having in your neighborhood!
[anybody know who designed these pre-cast concrete pieces?]
I have to say that without a doubt, this is the most complex network that I have yet attempted. Not only are there far more numbered routes than in the Interstate system, but there are also historical extensions and branches of many routes to consider. In some cases, numbers that were used once were reused in different parts of the country (see U.S. 48, which has been used for three completely separate roads!). I have attempted to show these historical roads as thinner route lines “behind” the main network, including the most famous U.S. highway of all – Route 66, which gets special treatment, being solid black in colour.
With forty miles between the Sun to Pluto (Presque Isle and Houlton) and recently expanded beyond to Eris(!) another 40 miles further, the Maine Solar System Model (MSSM) resides in Aroostook County in Northern Maine at the scale of 1:93,000,000. It serves as both an educational tool and tourist destination/local point of pride. Just another piece of astronomic urbanism, one of dozens large-scale solar system models around the planet that are changing our cultural landscape.
Beyond the hoped for economic gains of tourism, these astronomic models seem focused on educating local residents. Since most acts of good citizenry require scientific literacy, these large-scale models do (indirectly) inspire community building. So unlike Corner/Waldheim/Mostafavi/Reed’s theory of landscape urbanism, astronomic urbanism is more about image and knowledge, than creating places. It is also interesting to note that most efforts in astronomic urbanism are really astronomic ruralism, with only a few examples of architectural expression like the Ericcson/Globe Arena in the Swedish Solar System [below].
Housed in the Museum/Folsom Hall of the Presque Isle campus of the University of Maine, the sun is the only indoor piece of the model – the planets are mounted on 10′ tall poles along Route 1 (except Pluto).
As I pack up my UMN office, there are piles of books that are worth sharing, before they go into a box. Here are just a few of them in no particular order:
This is a well researched and comprehensive book that explores methods of shrinking the urban heat island. It’s worth noting that Gartland provides the best explanation of albedo and emissivity I’ve yet to encounter. Where the book falls short, is it doesn’t consider going against the status quo of development and engineering practices (i.e. increasing density, or narrower streets), instead just discusses using different low albedo/pervious materials and the usual fixes.
A slim volume that lays out the philosophical case for creating living cities. Doesn’t get bogged down in the technical details or process, and occasionally falls into thinking that biomimicry or a pretty garden equals a fully functioning and resilient ecosystem. Overall a good introduction to the concepts of eco-cities.
Unique among the dozens of big picture saving the planet books I’ve read over the last two years. The book is framed as a letter to a governor, which allows for discussion of policy and regulations at the state level. The author also uses examples from his personal life to keep the book from becoming too dry. Very well researched, and a good introduction for business minded folks that need the economic case made for changing their own/corporate behaviors.
