Heron's windwheel

Heron's windwheel is an ancient device that converts wind energy into mechanical motion. It consists of multiple blades or paddles attached to a vertical wheel. When the wind blows, it pushes the blades, causing the wheel to rotate. This rotation can then be used to perform work, such as grinding grain or pumping water. Heron's windwheel is an early example of using natural forces to generate useful mechanical energy, illustrating fundamental principles of renewable power and mechanical engineering.
