Quick Summary

Vertical-axis wind turbine
Vertical-axis wind turbine A Darrieus wind turbine harnesses wind energy using curved blades along a vertical axis.

The Darrieus turbine is a type of vertical-axis wind turbine (VAWT) patented in 1931 by G.J.M. Darrieus. Its design features two curved blades, resembling those of a food mixer, that are tied to a central shaft at the top and bottom and bowed outward in the middle. These turbines are capable of harnessing wind from any direction.12

However, Darrieus turbines are not self-starting and require an external motor to begin operation. While several models have been built, most VAWTs, including the Darrieus design, are not yet economically competitive with horizontal-axis wind turbines (HAWTs). Despite this, research and development continue for VAWTs, particularly for building-integrated wind energy systems.12
