The SEP Wind Turbine is ready-assembled and can be used to carry out a wide range of experiments on wind power. The blades of the turbine can be easily attached, removed or adjusted, allowing students to investigate the effects of changing the number, pitch, size and shape of the blades. Some of the effects can be quite counter-intuitive and require students to think carefully about the concepts of energy and power. The turbine has a DC output. Supplied assembled.
