ABSTRACT:
An automotive grill having at least one wind driven rotatable turbine which is adapted for attachment to the air-inlet of a conventional automobile. The turbine is releasably mounted to the grill in a manner such that airflow or wind through the grill causes rotation to be imparted to the turbine structure. The turbines may create an interesting abstract decorative effect or may be used to re-direct the flow of incoming air or even to turbulate the incoming airflow prior to passing through the radiator and/or condenser coil of a conventional automotive air-conditioning system. The turbine structure may include one or several turbines which are selectively mounted on the grill in various orientations in order to be aesthetically coordinated with the pattern or styling of the grate portion of the grill or even other portions of the automobile.
