Vertical-Axis Wind Turbines

Wind machines whose rotor turns about a vertical axis, including Savonius, Darrieus and panemone designs. A technology belongs here when its cited article describes a vertical-axis wind turbine. Because the rotor turns about a vertical axis, these machines accept wind from any direction without turning toward it, which is the main difference from the familiar three-bladed horizontal-axis turbine. A technology is placed here by the rotor layout the cited article names.
