Abstract

A cross flow turbine having one or more aerofoil blades (2) rotatably mounted about a central axis (3) and connected to said axis at or near each end of the one or more blades. The blades have a degree of torsional flexibility that make them twistable about the longitudinal blade axis to reduce the aerodynamic efficiency of the blades to control the rotational speed of the turbine. The twist of the blades can be actively controlled by means of a spring (12), other mechanical actuator or motor.
