About This Item

 

Full Description

Prior to the late 1800s, rotating shaft power was limited mainly to trains and ships. There were wind and water mills for pumping water and grinding grains and some steam-driven water pumps and ventilation fans. However, few people lived in windy regions or near fast-moving streams. Some ventilation fan designs for mine shafts were powered by man, wind or water pressure.
