What Are Vertical Axis Wind Turbines?
Vertical axis wind turbine is a type of wind turbine that has its rotor shaft installed vertically and can therefore work even if the turbine is not directly pointed to the wind. This ensures wind power even in areas where there is low wind speed. There are many types of these turbines. These include the eggbeater type turbines, the Gorlov helical turbine, the Savonius wind turbine, the Giromill, the variable geometry wind turbine, and the Lenz wind turbine. With the growing popularity of these Turbines, there is now a need to identify the advantages and disadvantages that are attached with the use of these structures. Vertical Axis Wind Turbines, more commonly referred to as VAWTs, have the generator and gearbox assembled near the ground instead of these parts being supported by a tower. This proves to be advantageous especially considering maintenance purposes. Part of the disadvantage of using a wind turbine is the difficulty of setting up a tower to put it up. With these turbines,
