Turbines? Who Needs Turbines?

Viktor Lawryniuk - Wednesday, August 24, 2011

Thanks to a friend I follow on StumbleUpon I read this article on Discovery.com today. “Wind Power Without the Blades: Big Pics” by Alyssa Danigelis is an amazing read about a project that came in second in the Land Art Generator competition sponsored by the planned city, Madsar, in Abu Dhabi. (Madsar itself is a work of environmentally-conscious design art.)

 The Windstalk project is the product of the New York design firm Atelier DNA and as proposed calls for 1,203 180-foot high resin-reinforced carbon-fiber “stalks” that spring from a 33-by-66 foot concrete base, starting at about a foot in width and tapering to two inches at the top. The stalks rely on a piezoelectric effect triggered by the sway from wind to generate power. Additional power is generated in the bases which contain a torque generator that converts the kinetic energy from the stalk into energy using shock absorber cylinders similar to the kind being developed by Cambridge, Massachusetts-based Levant Power. Atelier DNA estimates this system would generate power equivalent to that of a wind turbine farm installed in the same land area.

Tall, cattail-like stalks generate electricity by swaying in the wind.

Pretty cool, eh? No noise and looking like a work of art as well. Ms. Danigelis quotes Atelier DNA founding partner Darío Núñez-Ameni as saying “Windstalk is completely silent, and the image associated with them is something we're already used to seeing in a field of wheat or reeds in a marsh. Our hope is that people living close to them will like to walk through the field -- especially at night -- under their own, private sky of swarming stars.”

Not content with reinventing wind power, Atelier DNA is also working on an underwater version they call Wavestalk.
