Hybrid Car Idea

[John Coviello]

I had an idea for a hybrid car today.  How about putting one of those comact wind turbines on the roof of a car, not the big ones with blades, the one with a rotating wind turbine that looks like a cone.  Then as the car moves along it can generate electricity from the wind to charge the batteries.  I know it would not be a net energy generator or anything like that, but it could extend battery range pretty significantly.  Has anyone tried this?
