Is it possible to build a wind driven automobile using a set of sprocket and chains to drive a propeller system? Well indeed this makes sense because aircraft do this right? Sure, but aircraft do not have the tires on the ground or the friction considerations to deal with, because air is thin you see.
It may not be practical in the present period, but that does not mean that mathematically and scientifically it cannot be engineered you see? If the wind car was light and the propeller was strong then the car would be propelled and thus it would work. Aircraft taxi to the runway under their own power extremely well and have rather large bodies that they are moving too, which do not help them on the ground. So we already know that a car driven by a propeller could indeed work and we also know from Air Boats that we can put a fan shroud around the propeller to protect bystanders.
Do not leave too away, we will offer more information about the sprocket !
