Sadly it wouldn’t be possible to transform wind’s kinetic energy into movement for the windmill 
. What kind of windmill exactly are you looking for? Is it like those from the Netherlands? Or those attached to electric generators?
Also, does this kind of windmill have speed limitations? Most of them have some sort of limitation because otherwise they end up collapsing. If this is the case and you can determine the velocity-span, you could try to run multiple simulations for the range of the angular speed.
Just a thought though.
