Description
The ‘Windmill’ revolves around the principle of energy conversion and aerodynamics. When the wind hits the blades of a windmill, something magical happens: the mill turns that wind energy into electricity! Did you know that the design of the blades is very important? Because the number of blades, their shape and angle determine how well this conversion takes place.
In the past, windmills usually had four blades, but now you often see them with three. Why? The ‘Windmill’ allows us to study how much influence the number of blades has on the amount of energy generated. Companies use this knowledge to design wind turbines.
How many blades produce the most energy?
- Choose one of the windmills.
- Place the wind turbine between the fans.
- Press the green button to turn on the blower.
- See on the screen how much energy this windmill generates.
