Windpump

A windpump is a machine that uses the power of the wind to lift water from underground or surface sources to the surface, where it can be used or stored. It has a fan-like blade that moves when the wind blows and the blades spin a shaft connected to a pump below the ground. This pump then pulls water up and either collects it in a tank or sends it through pipes so it can be used where it's needed.
