An apparatus for converting wave energy to electrical energy in a sea environment comprises a flotation duck anchored to the sea bottom and a turbine assembly pivotally connected thereto comprising an air chamber partially filled with liquid and/or granular particles having a turbine mounted on the upper portion thereof. The turbine is either self-rectifying or with a flap valve controlled entrance to the air chamber. A generator is coupled to the turbine and driven thereby. In operation, the motion of the waves causes the liquid and/or granular particles to compress the air within the chamber which is then used to drive the turbine. The spent air is fed back into the air chamber from the turbine as wave motion continues. In alternate embodiments the turbine generator assembly is mounted to the upper portion of an air chamber open to the sea on the bottom in an apparatus which rotates about a fixed or stable central axis. Gearing arrangements to drive the generator either alone or in combination with a liquid or air turbine drive are also disclosed. Compression of the air within the chamber or liquid, as the case may be, drives the turbine. Multiple assemblies may be readily coupled together to generate electrical energy in commercially practical quantities.
