About this objectThe water turbine, an encased waterwheel, was developed in the early 19th century. Leonardo's horizontal impulse wheel, driven by the weight of falling water, and his hydraulic screw were important steps in this direction. Like the turbine, the hydraulic screw works with greater efficiency and a smaller water supply than the older overshot or undershot type waterwheels.
