Quick Summary

The field version in three minutes.

A water wheel is one of the oldest ways to turn moving water into useful work. It does not need fuel, batteries, or electricity. If water keeps moving, the wheel keeps working. Build a small working water wheel that turns a shaft from moving water, with the anatomy, water-feed types, and limits explained clearly.
