The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

Assemblies systems, and methods are disclosed for generating energy from natural forces and, more particularly, to energy generation using tidal action. A tidal energy conversion assembly includes a displacement vessel housing a directional converter that is coupled to an electrical power generator. The tidal energy conversion assembly further includes an anchor cable having a first end, a second end connected to the directional converter, and a length in between the first end and the second end. The anchor cable may be threaded through an anchor at a stationary location, such as a sea floor. The rising, falling, and/or drag forces of the tide cause a change in the length of the anchor cable thus exerting a force on the directional converter. The directional converter converts this force into rotational energy that may be harnessed by the electrical power generator to generate electricity for consumption.

According to an exemplary embodiment, a tidal current power generator includes a main frame including first and second sprockets rotated together with a chain and a guide rail for supporting the chain, the main frame being arranged in parallel with the direction of the tidal current of seawater; a plurality of operating bodies mounted on the chain and guided by the guide rails, the operating bodies including an inner shaft projecting to both sides of the outer surface and an outer pipe accommodating the inner shaft; a plurality of power plates combined with the outer pipe configured to forcibly move the plurality of operating bodies in the direction of the tidal current by the force of the tidal current; a pair of clutch jaws formed to face the inner circumferential surface of the outer pipe and the outer circumferential surface of the inner shaft and is engaged with or spaced from each other by axial movement of the outer pipe; a locking part configured to move the outer pipe so that each of the clutch jaws is engaged with each other; and a release part configured to move the outer pipe so that each of the clutch jaws is spaced apart from each other.

A generator for converting tidal fluctuation to electrical energy is provided. The generator includes at least a first energy transfer mechanism. The first energy transfer mechanism includes a weight that is floatable in water. The first energy transfer mechanism further includes a first driver gear and a coupling rod connecting the weight to the first driver gear. The coupling rod rotates the first driver gear when the weight rises or lowers while floating on the water. Therefore, linear vertical motion of the tides is converted into rotational motion. A rotor is rotated by the first driver gear when the first driver gear is rotated by the coupling rod.

A tidal energy converter has a pivoting lever that moves in response to tidal fluid moving other elements on the converter. The pivoting lever can be operatively coupled with an electricity generator to produce electricity. Namely, the pivoting lever may be coupled to an air source and compress the air to create a compressed air. The compressed air may be used to power an electricity generator. The pivoting lever is moved by fluid that empties from a feed tank to a spill tank. There may be one or more ballast tanks connected to the feed tank and/or the spill tank. Some of the feed tanks work in opposing unison with one of the ballast tanks.

The invention relates to a tidal wave powered device and a method thereof for producing potential energy from the movement of tidal waves in a water mass, the device comprising a cylinder (18) anchored to the bed (22) of the water mass with a piston (16) located in the cylinder to define a pumping chamber (25) therein. A storage tank (23) is located at an elevated height for storage of water delivered from the cylinder pumping chamber (25). A docking unit (30) anchored to the bed of the water mass is connected to a floater (10) such that when the floater (10) attains an optimal height, the docking unit (30) is locked in to hold the floater (10) in an elevated position. The docking unit (30) is opened to release the floater (10) from the elevated position so that the weight of the floater pushes the piston (16) downwards to deliver water from the pumping chamber (25) of the cylinder (18) into the storage tank (23).

One example method for real-time monitoring of wave conditions includes receiving, from a buoy over a first wireless communication channel, information based on continuously monitoring one or more characteristics of the wave conditions, receiving, from a user device over a second wireless communication channel, user preferences, and transmitting, to the user device over the second wireless communication channel, a message based on the information and the user preferences in response to a user request. Another example method includes transmitting, to a remote server, user preferences and a user request, and receiving, from the remote server and in response to the user request, a message based on the user preferences and information corresponding to the wave conditions. In these methods, the time duration between communication of the user request and the information acquisition may be less than a predetermined value.
