A wave energy conversion system is provided including a pod, multi-radius energy transmission mechanism, and an electrical generating device. The pod is rotatably supported by a platform structure and the multi-radius energy transmission mechanism is in mechanical communication with the pod.

This disclosure provides improved nautical craft that can travel and navigate on their own. A hybrid vessel is described that converts wave motion to locomotive thrust by mechanical means, and also converts wave motion to electrical power for storage in a battery. The electrical power can then be tapped to provide locomotive power during periods where wave motion is inadequate and during deployment. The electrical power can also be tapped to even out the undulating thrust that is created when locomotion of the vessel is powered by wave motion alone.

Disclosed is a wave amplification power-generating boat, comprising float systems (1), a support system (2), a hydraulic turbine power-generating system (3) or a float power-generating system (7) or a canard-type power-generating system (8), a wind rudder system (4), a propeller (5), a mooring system (6) and a wave detector system (9). The float systems (1) are capable of moving on a support; the support system (2) is used to connect the float systems (1) at two ends, with the hydraulic turbine power-generating system (3) or the float power-generating system (7) or the canard-type power-generating system (8) installed in the middle, and installing the wind rudder system (4), the propeller (5), the mooring system (6), and the wave detector system (9); the hydraulic turbine power-generating system (3), etc., works and generates power by utilizing amplified waves in the middle of a boat; and the wave detector system (9) is used to detect and compute an average wave length, to adjust in a timely manner a distance between floating points (101) at two ends to be as close to the wave length as possible, and adjust the direction of the boat to be consistent with that of the wave. The wave amplification power-generating boat enables a high wave energy conversion efficiency, and has a very strong ability to wind and waves.

A hinge system and method for an Articulated Wave Energy Conversion System (AWECS) that provides for hinge and piston pump displacements due to multi-axis forces in allowing adjacent barges of the AWECS to pivot with respect to one another due to wave motion. The hinge system uses a plurality of parallel hinges, and axle segments, coupled between adjacent barges wherein the hinges are coupled to upright trusses positioned transversely along facing edges of each barge. Hinge bracing includes lower V-shaped struts that act as lower stops when the barges pitch up and also include upper struts that act as upper stops when the barges pitch down. The pumps are positioned in parallel. The pumps have special couplings such as ball joint couplings that permit motions other than longitudinal pump/ram motions due to multi-axis forces generated by the wave motion and thus provide omni-directional stress relief to the pumps.

The present invention is a kinetic inshore wave energy conversion (WEC) device which uses the force of the wave to convert ocean water to pressurized water to eventually push on the blades of a turbine on shore to generate electrical energy. The WEC structure is affixed to a pipe reef structure with these pipes filled with water, submerged in the ocean and anchored to the ocean floor by a multiplicity of anchors. The dedicated pipes can run from any distance and extend all the way up to and underneath the shoreline and into a structure on shore which retains the turbine to convert the head pressure of the sea water to energy.
