Submitted by Alessandra Rapaccini and Giacomo Sanna, the CitySpeed Turbine turns transit tunnels into modular turbines that harness wind power from passing vehicles. The potential for energy is impressive--according to the NY/NJ Port Authority, approximately 202,000 cars pass through the Lincoln and Holland Tunnels each day. Combine that with train tunnels, and the device could be a significant energy source.
