ABSTRACT:
New and improved methods and means are described for the efficient, expeditious, economical, and safe conversion to usable form of almost all subsurface wave energy available within a predetermined annular region spanned by an array of submerged wave energy removing impellers mounted upon an annular outrigger surrounding and secured to a seagoing central platform. Maximal progressive inward attenuation of practically any state of the open sea is achieved over a very broad wave frequency band by buoyant, nonbuoyant, and neutrally buoyant impellers that function approximately as generalized simple pendulums whose natural frequencies fall at regular intervals throughout that frequency band. Optimal functioning of the impellers is achieved by assigning to their working members suitable degrees of omnidirectional response to water movement interial and drag forces, respectively. After conversion by pumps, the extracted wave energy is conveyed via a pressure transmission subsystem to a central turbine for further conversion and subsequent storage and/or product processing within the central platform.
