How is the swept area of the Magenn Air Rotor compared with that of the traditional turbine?
Wind Turbine swept area efficiency is crucially important to a flat plate wind turbine, but in our case it is not, since we can increase the size of our rotor at little cost and get equivalent or better “economic efficiency” per unit of swept area. Magenn uses 40% to 50% of our total rotor frontal area to calculate swept area efficiency. What is important is the overall cost and the rated output.
