Methods, systems, and devices are disclosed for wave power generation. In one aspect, a wave power generator device includes a stator assembly and a rotor assembly encased within a tube frame. The stator assembly includes an array of inductor coils in a fixed position within a cavity of the tube frame and a plurality of bearings coupled to the tube frame. The rotor assembly includes a turbine rotor having a central hub and peripheral blades coupled to a high inertia annular flywheel that is moveably engaged with the bearings of the stator assembly, and an array of magnets arranged to be evenly spaced and of alternating axial polarity from one another extending from the annular flywheel into the cavity between the array of inductor coils, such that electric currents are produced based on magnetic field interaction of the magnets with the inductor coils during the rotation of the annular flywheel.

A tidal power generation device includes a container assembly and a power generation device arranged in the container assembly. A water inlet of the container assembly allows a tidal water flow to enter. An entrance guide plate of the container assembly causes the water flow to advance in the direction of the power generation device to push the power generation device's thrust plates, and thereby driving the power generation device's thrust plate traction mechanism to make a power generator of the power generation device convert kinetic energy into electrical energy. After the water flow pushes the thrust plates, it enters a pressure accumulating pool of the container assembly. Then, the water flow in the pressure accumulating pool flows to a backflow guide plate of the container assembly, and flows to a first pressure relief pool of the container assembly to continue pushing the thrust plates.

Disclosed embodiments provide a renewable power generation apparatus. In embodiments, the renewable power generation apparatus is driven by wind. In other embodiments, the renewable power generation apparatus is driven by water. Disclosed embodiments utilize two cylindrical turbines placed adjacent to each other. A diverter directs wind towards both turbines, causing them to rotate about their respective longitudinal axis. The turbines are coupled to a driveshaft that drives a generator to generate power. Embodiments utilize an airfoil adjacent to each turbine. The airfoil causes air to move faster over the airfoil surface to create low pressure which increases the performance of the turbines. The renewable power generation apparatus of disclosed embodiments is relatively compact compared to a traditional wind turbine. This allows disclosed embodiments to have more flexibility in where they are installed, facilitating local power generation, off-grid applications, and other important environmental applications.

Systems and methods for hydro-electric power generation are disclosed. The system includes a frame or structure positioned in a waterway or channel, with one or more hydro-transition units secured to corners of the frame. The hydro-transition units include a body of reinforced fabric for redirecting water flow towards the inlet of the frame, effectively increasing the current of the water and allowing for turbines within the frame to generate power at an increased rate. Anchors and bracket systems may secure the hydro-transition units to both the waterway and the frame, thereby allowing the body of reinforced fabric to withstanding force from water-flow within the waterway. The system includes various failsafe mechanisms for disengaging or detaching the hydro-transition units from the frame and/or anchor for reacting to high water flow or volumes (e.g., flooding).

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.
