3. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   Wind turbines convert wind energy to electrical energy for distribution. Conventional horizontal axis turbines can be divided into three components: The rotor, which is approximately 20% of the wind turbine cost, includes the blades for converting wind energy to low-speed rotational energy.

4. Darrieus wind turbine - Wikipedia

   en.wikipedia.org/wiki/Darrieus_wind_turbine

   The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds. There are several closely related wind turbines that use straight blades.

5. Vertical-axis wind turbine - Wikipedia

   Furthermore, the blades of the Darrieus wind turbine can be shaped into a helix to reduce the torque ripple effect on the turbine by spreading the torque evenly over the revolution. Being lift-type devices, the Darrieus wind turbines can extract more power from the wind than drag-type wind turbines, such as the Savonius wind turbine.

7. Savonius wind turbine - Wikipedia

   en.wikipedia.org/wiki/Savonius_wind_turbine

   The Savonius wind turbine was invented by the Finnish engineer Sigurd Johannes Savonius in 1922 and patented in 1926. [1] [2] Europeans had earlier experimented with curved blades on vertical wind turbines for many decades.
