摘要： a system for creating energy from a buoyancy-gravity cycle of a plurality of buoyant containers, cyclically moving sequentially though a liquid buoyancy column and a gravity slide, where a buoyant container captures liquid from a basin at the bottom of the system, is then inserted into the liquid column through a series of coordinatedly openable gates or valves, that maintain the liquid within the liquid column to deposit the volume of liquid into a tank that feeds a hydroelectric penstock and turbine system, to create electricity, while liquid from the tail race returns to the basin at the bottom of the system.

摘要： System for power generation from a flow of fluid, comprising a fluid driven device connected to a tether wherein the tether is coupled with a base station to convert energy from the flow of fluid into transportable energy, wherein the fluid driven device comprises a frame provided with adjustable vanes, and wherein the vanes are adjustable for setting into a predefine position relative to the flow of fluid. The fluid driven device comprises a working mode and a retraction mode, wherein in the working mode the vanes are set in a first predetermined position to generate a lift force from the flow of fluid, and wherein in the retraction mode the vanes are set in a second predetermined position to provide a low drag level to the flow of fluid, and wherein the work performed during working mode is larger than the work supplied during retraction mode.

摘要： A wave power converting device includes a platform, a plurality of first and second fluid guide assemblies and floating assembly. The platform has a retaining post anchored to an underwater ground. The first and second fluid guide assemblies are disposed underwater so that the water could flow into the first and second fluid guide assemblies. The floating assembly could be moved up and down relative to the platform so as to press the water upwardly through the first and second fluid guide assemblies to a reservoir. Under this arrangement, the energy potential of the water in the reservoir can be converted into electrical power.

摘要： A fluid turbine apparatus for use with a turbine comprising a convergent section, a fluid turbine section adjacent to an outlet of the convergent section, and a divergent section adjacent to the fluid turbine section. The fluid enters through the convergent section and exits through the divergent section. The convergent and divergent sections are constructed using a modular grid-like structure supporting retractable wall panels. The internal vacuum created by the diffuser and the wind shear stresses on the convergent and divergent sections can be limited. Configurations of the convergent and divergent sections can be adjusted to suit prevailing wind velocities. Barriers of rotating deflectors are used to increase the effective area of the convergent and divergent sections during low wind conditions. Horizontally mounted aerodynamic deflectors may be used to decrease wind shear and drag on the divergent section, the turbine section, and on side walls of the convergent section.

摘要： A hydropower generating turbine having an impeller housing disposed to receive water, at least one impeller disposed within the impeller housing, at least one adjustable duct pivotally connected to the impeller housing, and, where the duct has a plurality of duct leafs, wherein the duct leafs articulate and cause the duct to converge and diverge for selectively disposing a fluid about the impeller. The ducts may be inflow or outflow ducts, and the turbine may react to a change in the fluid and alter the shape of the impeller. Further, the turbine may have an automated controller where variable change in the flow is detected by a sensor and transmitted to the automated controller to cause a directional shift in the multidirectional turbine.
