Harvesting the Wind  

Posted by Big Gav in

Metropolis Magazine has an article on a plan by some French designers to build wind turbines on power transmission pylons (something Bucky Fuller suggested decades ago, though he seems to have been forgotten) - Harvesting the Wind.

From the window of a TGV hurtling through France, the countryside flattens to a smudge—electrical towers rise and recede in clusters, and tall, lanky wind turbines seem to whip off pirouettes like a young Moira Shearer. Most passengers turn their heads, nodding off on a neighbor or burying their noses in Le Monde, but for a tri­umvirate of young designers, the sight is a view of the future. The passing turbines and pylons augur a new way to harness renewable energy in a country that relies almost entirely on nuclear power. “When we’re riding on the train, we al-ways see pylons, and some turbines too,” Nic­ola Delon says. “We say, ‘Both are here. Can’t we mix them together?’”

Delon, who is 31 and an architect, is the recip­ient of Metropolis’s 2009 Next Generation prize, along with Julien Choppin, also a 31-year-old architect, and Raphaël Ménard, a 34-year-old engineer. Their project, Wind-it, addresses this year’s theme—which beseeched entrants to “Fix Our Energy Addiction”—with the effortless simpli­city of a Pythagorean proof. The team proposes inserting wind turbines into existing electrical towers or, where infrastructure is broken or spare, building new towers that double as wind-power generators, thus introducing a fount of renewable energy into an aspect of civilization that’s as certain as taxes. With three potential sizes, the turbine towers could be integrated nearly anywhere: Lille, France, China’s Sichuan Province, or the streets of New York City.

It’s a pitch-perfect echo of the cultural moment. In the past decade, sustainability has become a moral imperative on the order of civil rights. Coun­tries across Europe, including France, are clambering to meet an EU-wide goal of drawing 20 per­cent of energy from renewable sources by 2020, and the United States, after eight years of cowboy environmentalism, is finally catching up. President Obama’s stimulus package allocates almost $50 billion to energy, most of it renewable. At the same time, the global economic crisis has turned lavish building plans into symbols of excess and redirected shovels at the long overdue, if unglamorous, task of improving public infrastructure. As Valerie Fletcher, executive dir­ector of the Institute for Human Centered Design and one of the contest’s judges, tells it, this is not an era for designers to tinker at the edges. “Things that might’ve been dismissed as pie in the sky, suddenly we were looking at them for potential practical use,” she says. “This was a time we had to think big.” Plenty of runners-up did just that—one calls for new zoning laws to allow mixed-use development in suburban subdivisions; another hopes to curb driving commutes through a centralized bicycle-loan system—but Delon and his team went a step further. “If you can change how energy is generated,” Fletcher says, “then you really have something that can change how we think about energy and how we use it.”

With its vast stores of largely untapped wind power, France is in many ways the consummate lab­oratory. Gales spread south from the English Chan­nel into Normandy and gather at the shoals of the Mediterranean, where they spring upon the ancient Languedoc-Roussillon with rampart-jolting abandon. The most famous, the mistral (Provençal for “masterful”), is said to master everything in its path; last year, it helped the windsurfer Antoine Albeau capture the world speed record. It is also believed to drive residents to hair-pulling, eye-bulging, bats-in-the-belfry madness, not unlike California’s Santa Ana winds.

France expects to swell its wind-power capacity more than five times over by 2020, a plan that would require an army of new wind farms and has already inspired fierce opposition from the NIMBY brigades—fierce, even, for a country that considers protest a national sport. “There are a lot of people who are against wind turbines because they say it disfigures the landscape,” Delon says. “They say it’s awful and terrible and blah, blah, blah. We don’t agree, because we say, ‘We don’t have a choice. We prefer that instead of more nuclear plants.’”

Ménard has made a career out of marrying good motives to unlikely architecture. As director of Eli­oth, a 20-person conceptual- and experimental-research arm of the large French engineering firm Iosis Group, he has spent six years tackling complex engineering problems that often involve insin­uating sustainable features into structures that aren’t exactly gracious hosts. Among them: Jean Nouvel’s Tour Signal and Valode & Pistre’s Tour Generali, two vanity skyscrapers slated for Paris’s démodé business district. Ménard has been trying to green them with small wind turbines. “This is quite in fashion,” Ménard explains. “It gen­erates between two and five percent of the consumption of the building, but they are still little, tiny things. There is no reason they can’t be bigger.” Thinking about battles over new energy infrastructure, and mindful of the ubiquity of (and relative lack of controversy surrounding) existing infrastructure, Mén­ard started sketching wind turbines wedged into the landscape: on the side of a bridge, crowning an electricity pylon, filling a steel-mesh cone that looks like something out of Mad Max. He sketched the latter in 2006 while riding the TGV to Paris. ...

A group of Stateside experts, including electrical and environmental engineers, a public-utility company, a sustainability consultant, and a wind-turbine manufacturer, reviewed the proposal for technical considerations. The general consensus was that the adaptive-reuse model would be tricky to justify financially. Electricity towers aren’t built to accommodate wind turbines, so they would likely require structural reinforcement, which could be either simple or prohibitively complex. The turbines would generate nom-inal energy—enough to power anywhere from one room in a house to 20 houses a year depending on size and wind speeds. They’re also more expensive up-front than their propeller counterparts, in large part because there isn’t much of a market for them. An added question is whether stacking turbines on top of one another from the ground up, kebablike, as Wind-it does, is the most economical means of capturing scudding gusts. As a rule, the farther you rise into the atmosphere, the more vigorous the winds and the more energy you’re able to harness. “There’s a slight naïveté about wind power’s potential in the design,” says Chris Garvin, a partner with the environmental consultancy Terrapin Bright Green, “but it’s compelling nonetheless.”

A marriage of towers and turbines isn’t unheard of. Urban Green Energy, a wind-power start-up in New York, recently mounted turbines atop the French telecom company Alcatel-Lucent’s cellular-communication spires. The turbines are nearly identical to those detailed in Wind-it. The major difference is that the Alcatel-Lucent system exhausts its power on-site; Wind-it proposes tapping into the grid. Anyone who has listened to Al Gore or (God forbid) T. Boone Pickens on the hustings lately knows that the American power grid is a great big Rube Goldberg machine, and a not very effective one at that. The grid is so clogged, archaic, and small that the areas where Wind-it could be most effective—the windswept prairies of North and South Dakota and the parched plains of Wyoming—are unfit to relay electricity to the cities where it’s most needed. It’s an obstacle for any wind-power entrepreneur in the country. For a fresh enterprise that leans almost entirely on existing infrastructure, it could be the coup de grâce. “The most efficient way to go about this,” says Nick Blitterswyk, cofounder of Urban Green Energy, “would be to build new towers.” Many of the experts we consulted agree. Wind-it XL was designed as a two-in-one package. It minds several, if not all, the issues above and would be best suited to regions where the nuts and bolts of modern civilization remain unassembled.

I think it is nice to see some of the things you and I talk about on this blog come to fruition over the years... like wind turbines mounted on power line and cell phone towers.
There is real progress happening.

However, there is so little progress I see in 'wind where it is needed and wanted'. The massive investment potential just is just being wasted on scale collapse.


The Buck stops here: You can't scale sustainable energy around an unsustainable communities.


The bucky idea around this is 'building communities around that communities resources'... and not 'scaling up' and building power resources around wasteful communities.

ANY community can be built sustainable. But, when a community has been designed to be unsustainable from the start (like so many urban and suburban) trying to scale renewable energy to be renewable around this idea equals the same problem.

Without utilizing every available energy efficiency and existing building conservation standard FIRST, nearly all renewable energy programs are doomed long term.

My hope is that the new funding for wind, nuclear and renewable testing require baseload conservation options before implementing.

NO community should have to debate this for funding as there is little to argue with every dollar invested in conservation returning on that investment. This is NOT true on renewable scaled around gluttonous energy waste.


We can not Drill, dig nuke or fight our way into energy independence without cutting out the 70% of all energy wasted first.

I'm never a doom and gloom guy until I hear what a bureaucrats view point of future 'sustainable and renewable' energy is.
