This image is our vision for Sydney in 2050 – created for ZERO-FIFTY – that shows the city partially powered by a series of Wind Towers designed by us at SUPER RADICAL. The towers use vertical turbines within the structure to capture the wind's energy. To find out more, get your copy of ZERO-FIFTY. For reference, the sky underlay ‘Sky 12’ was taken by zaphad1, released on Flickr and reproduced under Creative Commons License CC BY 2.0.
