This system provides you with all the answers you need concerning the basics of using wind energy. With the help of curriculum-based trials, it discusses different topics which are necessary for understanding the functions of wind power plants.

The study of how wind speed, wind direction or rotor type influences the power output are only some examples of possible experiments. Both qualitative experiments for students from age of 11 to 13, and complete quantitative trials for physics lessons until the age of 19 are described in detail.

For the qualitative trials, the expansion Measurements without Measuring Tools is required.

Experiments:

• Influence of the wind speed (quantitative and qualitative)
• Start-up wind speed of a wind turbine
• Comparison of the start-up wind speed of a Savonius and a three-blade rotor
• Changing the turbine voltage by connecting several consumers
• Examine the wind speed behind the rotor
• Energy balance sheet of a wind turbine
• Calculating the efficiency of a wind turbine
• Storing electric energy
• Energy conversion in a wind turbine
• Examine colour wheels using a wind turbine
• Comparison of a Savonius rotor and a three-blade rotor (quantitative and qualitative)
• Comparison of two, three and four-blade rotors (quantitative and qualitative)
• Characteristic curves of a wind turbine
• Influence of the wind direction (quantitative and qualitative)
• Influence of the rotor blade pitch (quantitative and qualitative)
• Influence of the blade shape (quantitative and qualitative)
