Swedish architecture firm Belatchew Arkitekter wants to transform the existing Stockholm Söder Torn skyscraper by adding thousands of electricity-generating bristles to the facade (via dezeen):
From the firm’s website:
The straws of the facade consist of a composite material with piezoelectric properties that can turn motion into electrical energy. Piezoelectricity is created when certain crystals’ deformation is transformed into electricity. The technique has advantages when compared to traditional wind turbines since it is quite and does not disturb wildlife. It functions at low wind velocity since only a light breeze is sufficient for the straws to start swaying and generate energy.
The design is as much an attack on the original building’s post-modern ethos as it is about wind-energy capture in a dense urban center that is less disruptive than more typical wind farms. The architects propose chopping off the conservative top of Henning Larsen’s design and replacing it with 16 additional floors on which they could attach more straws, thus capturing additional energy.
