A floating drum turbine is used for generating the electrical energy from the kinetic energy of a water stream (sea wave or river flow) that provides the mechanical energy needed to rotate an electrical generator for generating the electricity. The drum turbine is installed on a buoyant skid anchored to the seabed by some chains/ropes to keep it in a fixed position and direction along the water stream. The turbine is coupled to an electrical generator with a power transmission system, and generates the electricity that is transferred to the coast using a cable system floated on the water surface.

A sea wave energy converter system, including a plurality of pioneer devices each of which is mounted on individual towers installed at a seabed, wherein each of the pioneer device includes an assembly having a set of gears connected to at least one fly wheel, at least one paddle, and a generator, wherein each of the pioneer devices mounted on the individual towers are lined-up in a particular arrangement covering a length of a sea crest so that incoming kinetic forces of sea waves rotates seriatim the at least one paddle of each of the pioneer devices to rotate the generator through the set of gears to generate electricity individually by each of the pioneer devices and wherein the particular arrangement is one of a diagonal arrangement, a cross arrangement, and a ‘V’ shaped arrangement.

A modular wave energy converter comprising a rotating wave-receiving chamber made of several working chambers in the form of toroidal segments open on one side and closed on the other side by a valve, wherein the working chambers on one side and/or on the other side are closed by ventilation grilles.

A wave driven electrical generating apparatus has a vertically oriented wheel having a plurality of buckets spaced around a periphery of the wheel, facing in a direction tangent to the wheel, a support structure supporting the wheel on a horizontal shaft, and a generator connected to the shaft such that motion of the wheel turns the generator. The electrical generating apparatus is anchored, immersed in water in a location having wave activity, wherein the wave activity drives the wheel to create torque to drive the generator to generate electricity.

A breaking waves power generator includes a platform, a plurality of water wheels rotatably mounted within the platform, and a deck plate mounted within the platform. The water wheels include a plurality of vanes, blades, paddles, or buckets that, when impacted by breaking water waves, cause rotation of the water wheels. Breaking water waves can travel over the deck plate. The deck plate has an angular position and horizontal position relative to the platform that are adjustable to guide the breaking water waves so that the water waves break against the vanes, blades, paddles, or buckets of the water wheels, causing rotation of the water wheels from which power is generated. A ramp is connected to the platform in front of the water wheels, over which water is guided to the platform so that water waves break against the water wheels.

Disclosed is a power-adjustable wave power generator, comprising a support platform (1), a power generator (2), a rotary shaft (3), an impeller rod (4), a blade frame (6), blades (7), a synchronous movement mechanism and a lifting mechanism. The power generator (2) is arranged on the support platform (1) and connected to the support platform (1). The impeller rod (4) is radially connected to the rotary shaft (3). The blade frame (6), which is provided with several blades (7), is slidably connected to the impeller rod (4). The synchronous movement mechanism adjusts the distance of the frame (6) relative to the rotary shaft (3). The lifting mechanism adjusts the angle of the blades. The power generator can not only effectively generate power under the condition of small waves, but also can adjust extracted energy according to a full load of power generation when a wave force remains unchanged, and can automatically prevent a disaster under the condition of a catastrophic climate.

The deck plate is positioned underneath the water wheels. The water wheels have a radius greater than a maximum height of the breaking water waves, an axis of the water wheels being higher than the maximum height of the breaking water waves.

A water current energy generator comprises a barrel configured to rotate in a water current and a pair of air compressors secured on either side of the barrel. As the barrel spins, the air compressors are actuated and compress air into a cylinder. The compressed air is then capable of being accessed by means of a pneumatic hose.
