Building a bridge to renewable energy

Bridges are generally exposed to the elements, meaning they generally get a nice dose of sunlight often coupled with some fairly strong crosswinds. For these reasons this “Solar Wind” bridge design would seem to make a lot of sense. The proposed bridge would harness solar energy through a grid of solar cells embedded in the road surface, while wind turbines integrated into the spaces between the bridge’s pillars would be used to generate electricity from the crosswinds. The brainchild of Italian designers Francesco Colarossi, Giovanna Saracino and Luisa Saracino, the Solar Wind concept was designed for the Solar Park Works – Solar Highway competition that asked entrants to modernize sections of a decommissioned elevated highway stretching between Bagnera and Scilla in Italy. The road surface would replace traditional asphalt with 20 km (12.4 miles) of “solar roadways” consisting of a dense grid of solar cells coated with a transparent and durable plastic coating providing 11.2 million kWh per year. The designers say this system, combined with the 26 wind turbines integrated underneath the bridge generating 36 million kWh per year, would provide enough electricity to power approximately 15,000 homes.
