A rotary transducer adapted to be driven in the same direction by air flow therethrough in either axial direction comprises a rotor having blades of aerofoil cross-section which are fixed with their planes of zero lift normal to the axis of the rotor. An apparatus for use in extracting energy from the waves of the sea utilizes such a transducer.

Apparatus for extracting energy from a reversible fluid flow, comprising means supporting a rotary transducer in said flow, said transducer including a rotor having its axis parallel to the direction of fluid flow and being rotatable about said axis; a plurality of rotor blades extending radially from said rotor, each of said blades being of substantially symmetrical airfoil cross-section; and means rigidly mounting each of said blades on said rotor with the plane of zero lift of the blades permanently normal to the axis of the rotor so as to provide for continuous rotation of the rotor in a single chosen direction of rotation in response to reversible fluid flow.
