Build your own Gear Windmill and learn about gears and energy conversion.



Explore the differences of gears. When the teeth of a special gear are longer compared to a common gear, and the cogs (the space between teeth) are larger, the two gears will mesh better. As the crank is turning, the horizontal axis drives the gear device to change its direction of rotation. This demonstrates, in reverse, the process of a windmill converting natural wind energy into mechanical energy.
