The common target for vehicles has always been lowest fuel consumption. This paper deals with a new cooling fan for vehicle engine. This fan is used as a cooling fan at low speed or when the vehicle needs cooling. This fan is also used as a wind turbine and generates electric power at high vehicle speed. The fan has possibility to reduce the vehicle air resistance along with the regeneration of the electric power. We have developed a fan rotor that can operate as cooling fan with the same performance as the current fan and can operate also as a wind turbine at higher performance than the current fan. In this paper we report the influence of blade solidity on the wind turbine efficiency. The effectiveness of this proposal has been confirmed through the wind tunnel tests and CFD calculations.
