Design of a Vertical-Axis Wind Turbine

The vertical-axis turbine configuration offers some advantages for this application. Vertical-axis wind turbines (VAWTs) are generally simpler mechanically than a horizontal-axis type because they do not require any yawing mechanism to keep them pointed into the wind.

Vertical axis wind turbine - Wikipedia

A vertical-axis wind turbines (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.
