The Solar Wind Bridge is a concept from Italian designers Francesco Colarossi, Giovanna Saracino and Luisa Saracino and seems like one of those ideas, that makes you think, why isn’t this already in use.
The concept uses the span in between the bridge uprights to accomodate wind turbines together with solar cells embedded in to the bridges road surface. The design has been entered into the Solar Park Works, Solar Highway competition for a brief that required entrants to modernise sections of a decommissioned elevated highway stretching between Bagnera and Scilla in Italy.
The bridge design also incorporates greenhouses along its length providing a ‘green promenade’ to grow fresh fruit and vegetables, that can then be purchased along the roadside by drivers using the bridge.
The designers estimate that this system, with 26 wind turbines integrated underneath the bridge, could generate 36 million kWh per year and would provide enough electricity to power approximately 15,000 homes.
