Abstract: The present invention relates to a generator for generating power from a wave. The generator includes a body defining a plurality of chambers for receiving the wave, and a first set of non-return valves through which air from respective chambers can pass. A first vessel receives air from the first set of non-return valves and, in turn, a turbine receives air from the first vessel to generate power. A second vessel receives air from the turbine. The generator also includes a second set of non-return valves through which air can pass from the second vessel and into respective chambers, thus completing the fluid circuit.
