PROBLEM TO BE SOLVED: To provide a power auxiliary device for improving fuel economy of an automobile, a train or the like, and power generation device with exhaust gas and wind force.SOLUTION: A ventilation port and a ventilation pipe 7 are included in a body of a tip part of an automobile; an axial flow type rotary vane 2 is opposite to an air flow outlet of the ventilation pipe 7; and in running of the automobile, the rotational force of the rotary vane 2 is transmitted to a rotary main shaft 1, a dynamo integrated with the rotary main shaft 1 generates power, and fuel economy of the automobile is improved. Also, since power is generated with wind force even if an automobile is parked at a place where wind force is strong, and a battery can be charged, fuel economy is further improved. |
