Vertical-axis turbines look like egg beaters. Vertical-axis turbines have blades that are attached to the top and the bottom of a vertical rotor. The most common type of vertical-axis turbine—the Darrieus wind turbine, named after the French engineer Georges Darrieus who patented the design in 1931—looks like a giant, two-bladed egg beater.

A small, vertical-axis wind turbine has been mechanically coupled to a positive displacement pump for pumping from shallow wells or lakes. The 4-kW turbine is 5.5 m high and has an equatorial radius of 4.5 m. Power is transferred through an electric clutch, which allows the turbine to be started in a no-load condition (Fig. 8). The rotor ...
The History of Wind Power | TurbineGenerator
Around the 9th century AD in Persia many vertical axis windmills were used to grind grains and pump water from the ground. There were also many windmills used to grind and pump water in China around the 13th century AD and is often argued that the Chinese had invented the windmill much earlier than a timeline of wind power history suggests, but ...
