Highway wind turbines to capture energy from passing vehicles

"An Arizona State University student has proposed a very novel way of re-capturing some of the energy expended by vehicles moving at high speeds on our nations highways. The proposal would involve mounting horizontal wind turbines above the roadway that would be driven by the moving air generated by the passing traffic. The electricity generated by spinning these turbines could be fed back into the grid. Joe's analysis indicates that based on vehicle speeds of 70 mph each turbine could produce 9,600 kWh per year."



Looks a little crazy...Do you think we could actually be driving under these on I-95 pretty soon?
