The invention relates to a system that includes a wave energy converter and an assembly, adapted to be driven by the wave energy converter. The wave energy converter includes an array, in the form of rows and columns, of floating elements adapted to float on a sea surface in the vicinity of a shore. Each floating element has a first and a second end, each end being connected to a lever, the lever being connected through a bearing to a pivot point. Each lever is connected in an articulated manner to a piston rod in a wave-actuated liquid pump, that is in fluid communication with the pipe, adapted to lead a liquid to a workstation, wherein the workstation includes the assembly.

The telescopic hydrokinetic turbine system is a device meant for lifting the burden of manufacturing, installing, and maintaining hydrokinetic systems in the water. The device attempts to overcome the issues faced by present day hydrokinetic systems. To accomplish this, the device includes a light weight and easy to carry and install design, a telescopic pillar to align itself with the tide direction or even to leave the body of water for maintenance. Electrical parts are not submerged but instead remain onshore in a small cabin or housing. Further, by adding the use of multiple diffusers, the water flowing into the turbine is made smoother and the overload of water is able to be evacuated and swiped by the fins. The diffusers increase the blades working capacity while homogenizing the water flow and avoiding the phenomena of vibrations and cavitation, thereby increasing efficiency.

A sea wave generating device includes a floating base, a generating assembly, a driving assembly, and a guiding housing. The floating base includes a base body and a cover plate. The generating assembly is secured in the base body and includes a lower magnetic wheel and a power generator. The driving assembly includes an upper magnetic wheel and a blade wheel. The upper magnetic wheel and the lower magnetic wheel are attracted magnetically. The guiding housing is secured to the base body and rests on the cover plate. The guiding housing covers the blade wheel and the upper magnetic wheel. Thus, when the sea wave is introduced into the guiding housing, the seawater pushes the blade wheel which drives the upper magnetic wheel which drives the lower magnetic wheel which drives the power generator to generate an electric power.

A hydroelectric turbine designed to operate in a bi-directional reversing water flow caused by ocean waves, comprising an annular stator with two axially spaced sets of a plurality of guide vanes placed along its circumference that are inclined in the axial direction, an annular rotor with a plurality of concavo-convex blades placed along its circumference with an electric generator attached to it. The rotor is placed to rotate about its axis between the two sets of the stator guide vanes. Wherein, the stator and rotor are placed within the cylindrical part of an hourglass-shaped double funnel so when the ocean wave moves in one direction, the water flow enters the turbine through one end of the double funnel (inlet) and passes through the channels formed by one of the stator guide vane sets towards the rotor blades. The channels formed by the stator guide vanes are inclined at an angle to the rotor rotation plane, so that the water flows in the direction of the rotor rotation. After passing through the channels formed by the rotor blades and the channels formed by the other set of the stator guide vanes the water flows out of the turbine through the opposite end of the double funnel (outlet). When the wave moves in the opposite direction and the water flow direction reverses accordingly, the outlet becomes the inlet and the inlet becomes the outlet. The turbine keeps rotating in the same direction, transmitting the rotation to the electric generator and providing continuous high efficiency energy conversion.
