Vertical Water Axis Turbine
Vertical Axis Water Turbines (VAWT) are turbines with a vertical shaft. Foils connected to the vertical shaft makes this typical water turbine. The standard version is called a Darrieus turbine. Pitch control is developed for maximum efficiency and a high fish friendliness. The pitch control enables energy extraction from water currents at lower speeds.
Due to its geometry, the turbine is easely scalable. Therefore, the turnbine can be adapted to a wide range of existing constructions. Turbines of 1×1 meter, 1×2 meter, 2×2 meter, and 2.1×4 meter are fabricated and tested.
