Check out one of the design entries for this year’s GE Ecomagination Challenge. On first glance it’s your standard road tunnel but a closer look reveals its energy creating potential. The CitySpeed Turbine designed by Alessandra Rapaccini and Giacomo Sanna can help create energy for cities by utilising the strong air currents within the tunnel to power turbines. These modular turbines generate energy in the same way that a windmill does, only without the extra space that a windmill needs. This new design can be put into action in existing tunnels and is a great urban solution to producing energy.
The CitySpeed Turbine can work in both train and car tunnels. With hundreds of thousands of cars, trains and even bikes travelling around cities every day (202,000 passing through the Holland and Lincoln tunnels in New York every 24 hours) the possibility for inner city power production is gigantic.
