A parabolic or part parabolic focusing device located in the ocean comprises wall sections (5) which converge a parallel ocean wavefront to foci (9, 10) located in an air compression chamber (11) located between the wall sections (5), thereby providing a wave amplification effect, An oscillating wave surface produces an oscillating air column inside the chamber (11) to drive a self-rectifying turbine located in an outlet at the top of the chamber. The turbine comprises a rotor with radially oriented aerofoil shaped blades which are symmetrical in cross section about a transverse plane so that the turbine rotates in a single direction regardless of the oscillations in the air column. Several mechanisms to vary the pitch of the blades are also disclosed.
