Vertical-Axis Wind Turbine (VAWT): Working, Types, Advantages & Disadvantages …

Vertical-axis wind turbines come in one of two basic types: the Darrieus wind turbine, which looks like an eggbeater, and the Savonius turbine, which uses large scooped cups. Vertical-axis wind turbines were tested and used more extensively in the 1980s and 1990s because they were quieter and could operate without requiring yaw controls, regardless …
