The race to win GE’s “Powering Your Home” Ecomagination Challenge,  a contest that invites entrants to design the green home of the future,  is on. So far, all the entrants are impressive, but one stands out: a  proposal for transit tunnels that power cities.
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.
