The City Speed Turbine offers a new way to harness energy for urban settings. Essentially, it converts a transit tunnel into a modular turbine that gains wind power from speeding vehicles. Able to be placed into existing settings, it could greatly benefit cities around the world.
Designed by Giacomo Sanna, the City Speed Turbine was the winner of the Mini Design Award. Since it offers a new way for cities to harness energy, I wouldn't be surprised if these turbines are eventually put into play.
