Abstract: A water turbine for generating mechanical energy from a flowing fluid includes a rigid base that can be secured at a fixed position relative to the fluid flow. On the base, a substantially disk-shaped hub is rotatably mounted and at least one blade is positioned on the hub for rotation with the hub around a hub axis. Also, each blade is rotatably mounted onto the hub for rotation of the blade relative to the hub. For the turbine, each blade defines a chord line, and for each blade, a pitch angle can be defined as the instantaneous angle between the blade's chord line and the direction of fluid flow. The turbine also includes a sprocket and chain assembly to rotationally interconnect the hub to each blade. This assembly allows the pitch angle for each blade to be selectively varied during hub rotation.
