Since the Magnus effect was described in 1852, it is natural to try to drive wind turbines with it. As for the horizontal axis wind turbine, its structure is not difficult to understand as shown in the figure below. However, if it is implemented as a vertical axis wind turbine, the rotation directions of the cylindrical rotor on the windward side and the leeward side must be opposite, so that the torques will not cancel each other out, so as to drive the wind turbine. In the early days, it could only be made by means of gears and connecting rods, which was difficult to achieve because the structure was too bulky. In recent years, thanks to the rapid advancement of semiconductor technology, microcontroller and motor drive technology has matured, it is no longer difficult to realize this concept. The following video shows this original concept in the real world …

High-efficiency but difficult to self-start Darrieus wind turbine experiment – VAWT (2)

According to the literature, the Darrieus vertical axis wind turbine characterized by high efficiency but it is difficult to be self-starting. I couldn’t understand when I first came into contact with it. Since high efficiency means that it has torque, why can’t it start by itself? Later I realized that its efficiency must appear at a higher speed (similar to the high gear of a car), As for how high the speed should be? Usually 2~6 times faster than wind speed. This puzzles me even more, because the wind turbine is driven by the wind, why can it revolve faster than the wind speed? It seems that an experiment must be done, seeing is believing …

Due to the need for environmental protection and the fight against global warming, the development of renewable energy is urgent. In addition to solar energy, wind energy has attracted the most attention. In order to use wind energy, mankind has invented Wind Turbine for centuries. The wind turbine can convert wind energy into the rotating mechanical energy, and the torque generated by its main shaft can be used to drive a load, such as a generator or a water pump, for power generation or irrigation. According to the direction of the rotation axis, wind turbines can be divided into two types: horizontal axis and vertical axis.
