vertical axis wind turbine | vertical axis

A vertical axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is perpendicular to the ground, as opposed to horizontal axis wind turbines (HAWT) where the rotor shaft is parallel to the ground.

VAWTs typically have blades that are arranged around the central rotor, and they can have different designs, including Savonius, Darrieus, and Giromill. Savonius turbines have a curved shape and can operate regardless of wind direction, while Darrieus turbines have straight blades and are more efficient but require wind to come from a particular direction. Giromill turbines have straight blades and a vertical axis, and they are often used in residential and small-scale applications.

One advantage of VAWTs is that they are able to operate with lower wind speeds and in turbulent conditions, as they do not need to constantly align with the wind direction. They can also be quieter and more compact than HAWTs, making them suitable for residential and urban areas. However, VAWTs typically have lower efficiency than HAWTs and may require more maintenance due to their more complex designs.
