Reactive, reversible blade turbine for power generation and pumping water
12416283 · 2025-09-16 ·

A reactive blade turbine system works vertically, horizontally, or at an angle and clockwise or counterclockwise according to blade angle and locking position and adjusts to variations in fluid flow such as changes in tidal currents to generate power more efficiently regardless of direction of fluid flow. A method for generating electrical power from a continuous fluid flow via the reactive turbine system is also provided herein.

STATOR FRAME FOOT

A stator frame configured to carry a stator core of a vertical axis hydroelectric generator includes at least one stator foot that supports a weight force of the stator frame. The stator foot includes a frame side part and a ground side part, wherein the frame side part and the ground side part are slidable relative to each other. The ground side part and the frame side part have complimentary shapes such that the weight force exerted from the stator frame on the stator foot results in a reaction force on the stator frame that is non-parallel to the weight force.

This present invention relates to a method of recovering the forward momentum of an underwater or surface current, wind velocity and waves referred to a renewable energy and converting their kinetic energy to electrical energy or potential energy by a pumping system by the use of a cross flow vertical axis turbine with automatic turbine blade pitch positioning. Energy in the form of coastal surf waves is also a source of energy that can be recovered in useful form.
