overshot waterwheel
Quick Summary
An overshot waterwheel is a type of vertical waterwheel that uses buckets or cavities around its circumference. Water is directed over the top of the wheel, filling these buckets on the farther side. The wheel is primarily turned by the weight of the water in the buckets.1
Waterwheels, including overshot types, were among the earliest machines developed to harness natural energy sources for mechanical power. They were crucial for tasks like grinding grain, powering sawmills, and driving bellows for furnaces before the advent of steam power during the Industrial Revolution. An overshot wheel can achieve a higher efficiency of 63 percent compared to an undershot wheel, which has blades pushed by water passing underneath.23
