vertical waterwheel

A vertical waterwheel is a mechanical device that harnesses the energy of moving or falling water to create rotational motion. This rotation is then transferred via the wheel's shaft to machinery. Waterwheels were among the earliest sources of mechanical power, predating steam power, and were used for tasks like grinding grain, powering sawmills, and driving pumps.12

There are several types of waterwheels, distinguished by how the water interacts with them:
* Undershot wheels: Water flows beneath the center of the wheel.
* Breast wheels: Water enters around the middle of the wheel.
* Overshot wheels: Water flows over the top of the wheel.

These wheels were crucial for early industry, with many towns developing around locations with reliable water flow. While largely replaced by water turbines and steam power, waterwheels were a foundational technology in engineering.12
