The present invention relates to a power generation apparatus and, more specifically, to a freely-controlled power generation apparatus configured so as to generate electric power while being freely controlled under optimal conditions, since a cylinder body for supporting screws submerged under water is elevated by buoyancy or rotated according to the flow of the water.

An energy harnessing device for harnessing wave energy that results in pitch, sway, yaw, surge, roll, and heave movement, wherein the device effectively converts multiaxial translational and rotational motion to unidirectional rotational motion for power transmission.

A marine plant assembly comprising a floating vessel and a plant operating unit attached to a buoyancy vessel in such a way that the operating unit is at least partially submerged during operation. At least one link element provides a hinged connection between the operating unit and the buoyancy vessel, thereby to allow movement of the operating unit from its submerged operating position to above the water level and adjacent the buoyancy vessel by said link element rotating into a position substantially parallel to the buoyancy vessel.

A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.
