A proposed bridge concept that incorporates both solar panels and wind turbines into its structure could generate as much as 40 million kilowatt-hours of electricity per year.
The Solar Wind concept — designed by Francesco Colarossi, Giovanna Saracino and Luisa Saracino, who together make up Coffice — would add 26 wind turbines to an existing viaduct in south Italy, which the designers say could generate 36 million kilowatt hours of electricity per year. The turbines would be placed in the space between the existing viaduct’s pillars.
The designers also propose to place a park across the top of the viaduct which would feature solar greenhouses and panoramic viewpoints. The outer carriageway would remain accessible by vehicles, but the tarmac would be substituted with solar panels comprised of a dense grid of solar cells covered with highly resistant plastic.
The concept was entered into the Solar Park South (Parco Solare Sud) competition which sought to find new purposes for old, unused viaducts in Calabria, Italy. It came second only to an idea from French firm Off to turn the viaducts into vertical villages for people to live in, as well as gardens to attract local birds.
