An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

The hydroelectric generator using a conduit turbine is furnished with a driving shaft which penetrates the center of a conduit through which a flow passes to the inside; a conduit support main body which is provided so as to support the driving shaft; a propeller which is fixed to the driving shaft, and rotates by the movement of the flow; an internal gear which rotates together with the driving shaft from between the conduit support main bodies; an external gear which is driven together with a shaft, outside the conduit, as a rotational force is delivered to the internal gear; and an electric generator.

A subsea energy storage installation comprises a pumped-storage system having pumping and hydropower generation components for, selectively, converting electricity into potential energy by expelling water from within a tank into the surrounding sea and for generating electricity from an incoming flow of water re-entering the tank under hydrostatic pressure. The tank comprises at least one elongate rigid pipeline that may be lowered to the seabed as part of a towable unit or laid on the seabed as a pipe string launched from a surface vessel.

A facility for generating electricity includes a hydroelectric generating apparatus including an elongate penstock in flow communication with a source of water and a hydro-turbine and a plurality of water refill pumps for supplying refill water to a plurality of horizontal pistons on a synchronized and coordinated basis to supply pressurized water to the penstock. A pressure regulator is provided for supplying pressurized air to a storage container for supplying air to the pistons and respective air exhaust/release valves release the pressurized air in the pistons to the atmosphere after use. Respective water inflow valves are provided for refilling the pistons after the air exhaust/release valves open.

A runner for a hydraulic turbine configured to reduce fish mortality. The runner includes a hub and a plurality of blades extending from the hub. Each blade includes a root connected to the hub and a tip opposite the root. Each blade further includes a leading edge opposite a trailing edge, and a ratio of a thickness of the leading edge to a diameter of the runner can range from about 0.06 to about 0.35. Further, each blade has a leading edge that is curved relative to a radial axis of the runner.

A valve system for controlling the fluid flow in a duct, includes: a valve body adapted to be inserted in an interruption of the duct, and provided with an inlet and an outlet for a flow of fluid in the duct, a lateral flow valve, developing substantially transversally in the duct, placed in the valve body upstream of the fluid flow, the valve having an obstructer capable of moving transversally in the duct to “laterally” interrupt part of the fluid flow in the duct, an actuator adapted to move the obstructer from a first position, in which the duct is fully open, to a second position, in which the duct is fully closed, a rotor shaped substantially as a turbine, placed inside the valve body downstream of the valve with respect to the fluid flow, the rotor being located at a distance from the valve comprised within a pressure recovery zone, the pressure being generated by the valve in the absence of the turbine.
