An ocean wave energy extraction system and components thereof

摘要

The invention relates to wave powered energy extraction systems and the components thereof, in which the oscillating ocean wave motion is used to displace a volume of air to drive a wind operated turbine connected to an electrical generator. The various aspects of the invention include: a novel parabolic or part parabolic wave focusing device (1); an air compression chamber arrangement particularly suited for use with the novel wave focusing device; and an independently novel wind turbine operable to rotate unidirectionally under periodically reversing air flow conditions of the kind contemplated above.
