Auxiliary power source in motor vehicle operated by air resistance when travelling - has shaft about one metre long running in two ball bearings and equipped with three or more scoop shaped blades rotated by wind produced as result of travel

摘要

The auxiliary power source has a dynamo (3,3a) which is mounted on each end of a shaft and rotated with it. Each dynamo, e.g., charges a 12-volt battery. Three or more such bladed shafts with the dynamos and batteries provide the second power plant in the mobile vehicle. An approximately one metre long, 10-15 cm wide surface under the bladed shaft covers the wind produced by the air resistance, and conducts the wind to the upper half of the bladed shaft, and can act to block the travel wind. USE/ADVANTAGE - Auxiliary power plant. For travel in cities. Prim. petrol or diesel engine can be switched off to reduce pollution. Dynamo batteries can be re-charged by switching on engine.
