Such cars earlier also were designed by other engineering students.None of them were looking like a car.It takes alot of time before any such car is accepted by people.Such designs are ok as a design projects to final year engineering college students.No one will make them comercially.Perhaps the present look of a car with an alternate fuel and runs long distance may be the the ultimate requirement.So let the Engineering colleges have projects of such nature.It can also be a clloberation with the industry.
