An improved method of lifting fluid using the difference between atmospheric or higher boosted pressure and fluid vapor or vacuum pressure applied to a series of chambers with a movable plate that divides each into variable volumes, and comprises one stage of the system. Combinations of pressures in the chambers between the movable plates lift the fluid to a height where the fluid column base pressure equals atmospheric or boosted pressure less friction and mass losses. A vertical array of stages, each lifting fluid from the stage below it, allows fluid to be lifted to any height, limited only by structure or geographic elevation. Further; operating pressures are tapped from the top and bottom of a standpipe filled with static fluid, pressure changes are made when the volumes are zero, and the sum of the volume receiving fluid and volume delivering the fluid are constant, making the system closed. Once raised, the fluid may be released for it's end use and more particularly; through a power generator. Where the fluid is water in an open environment and fed through a turbine, the water may be returned to the system reservoir to be reused in the cycle or if in a closed system the fluid may be returned to a chamber under pressure for reuse.

A segmented augmented turbine assembly for generating electricity from a fluid in motion, the assembly comprising a segmented annular ducted channel extending between an inlet receiving the fluid and an outlet, the channel comprising a convergent accelerating the fluid, a segmented turbine-rotor section comprising blades and guide vanes rotating about a central shaft coupled to a generator, and a diffuser section configured to decelerate the fluid, wherein the channel comprises solid inserts attached to an outside face of the turbine-rotor section, the flow stream passing through open flow-through segments positioned between the solid inserts.

A water powered electricity generating assembly for continuous generation of electricity includes an endless track, which is rotationally engaged to a stand. The trays hingedly engaged to the endless track are uprightly and invertedly positioned on a first side and second sides of the endless track, respectively. A generator is operationally engaged to the endless track. A supply pipe is engaged to and extends from the stand so that a first end of the supply pipe opens above the first side of the endless track. The supply pipe extends to a water source at an elevation higher than the upper end of the stand and diverts water from the water source to the stand. The water fills the trays on the first side of the endless track, causing the endless track and the generator to rotate, thereby generating an electrical current.

An energy conversion system comprising: a riser conduit comprising a first liquid; a down-comer comprising a second liquid, the down-comer in fluid communication with the riser conduit, the second liquid comprising first liquid and finely divided material in suspension such that the second liquid has a higher specific gravity than the first liquid, the down-comer in fluid communication with a first tank and a second tank; a converter device arranged to convert energy of the first liquid into energy for output from the energy conversion system, and to discharge the first liquid thereafter; and a recirculator arranged to recirculate third liquid to maintain the finely divided material in suspension, the third liquid comprising second liquid and further finely divided material in suspension. The recirculator is arranged to discharge the third liquid to mix with the first liquid from the converter device to form the second liquid. The first tank and the second tank are arranged between the converter device and the down-comer, to receive the first liquid discharged from the converter and to supply the first liquid to the down-comer. Supply of first liquid to the first and second tanks is in use regulated to maintain the height of liquid in the first and second tanks below a predetermined threshold.

(EN) This invention relates to method and apparatus for extracting energy from water waves to generate electric power. The wave energy converter uses sea wave oscillations, from a land-based position. It understood a land-based power take off apparatus (3) that is oscillated by waves conveyed to it by canal or tunnel. The canal has a funnel shaped intake (1) at the coastline, a wave control gate (9) positioned near the intake and a power take off apparatus (3) positioned inland across the canal with a float (8) that works pumping cylinders (7) that pump hydraulic fluid to turn an impulse turbine (5) coupled to an electricity generator to generate electricity. The canal depth is predetermined to float the float, of the power take off apparatus (3), at all tide levels.

(1) Technical field of the invention described in the claims: natural laws regarding water flowing from a high place to a low place, and fluid dynamics regarding potential energy of water. (2) Technical objectives to be solved by the invention: A. Simultaneously producing electric power and pumping up water; B. Installing hydroelectric power stations in unlimited places, that is, guaranteeing that hydroelectric power stations can be installed anywhere; C. Guaranteeing that electricity is produced 24 hours a day, 365 days a year; D. Ending thermal power generation, nuclear power generation, photovoltaic power generation, and wind power generation. (3) The gist of a method for resolving the technical objectives: to guarantee that, in the course of water at a high level falling into a pipe, multiple generators installed in the pipe are operated, thereby producing electric power, that is, the gist is to increase the total amount of produced electric power. This is because the total amount of produced electric power can be increased as desired, while electric power (that is, cost) necessary for pumping up water that has fallen to the original high level is fixed. That is, the number of generators installed in the pipe can be increased as desired (to 100 or 1,000). (4) Important use of the invention: creation of a new-concept pumped-storage hydroelectric power station.

A pumped storage electricity generating system that includes a water feed line for introducing water into a pressure vessel. Water flow valves communicate with the pressure vessel to control introduction of water into the pressure vessel. A push plate is mounted for movement in the pressure vessel between opposed first and second motors, for example, hydraulic radial piston motors adapted for reciprocating the push plate linearly between a first direction wherein water is drawn into the pressure vessel through the water flow valves and a second direction wherein water is conveyed downstream through the water discharge line under pressure to the hydroelectric turbine. Other embodiments are double-acting and convey water to the turbine on each stroke.

The Submerged/Water-Level Turbine is a hydro-electric power generator. All possible designs characteristically generate power from a turbine by channeling a vertical flow of water to and from depths of a provided reservoir. Careful construction will be able to accommodate a full range of power demands by regulating the water level of the reservoir that surrounds the structure.

Gravity and hydrostatic pressure are natural forces that have considerable force generating capabilities which can make significant contributions during the operation of a FFWN 24/7/365, baseload, 100% clean energy power plant. When these natural forces are combined with compressed air in the upper part of an elevated storage tank containing a liquid and the partial vacuum created by powerful pumps to produce a targeted water flow rate velocity of about 31.3 m/s through the entire length of a coiled section of pipe containing one or more helical turbines in each coil that are connected to an external generator, the electricity produced during a power producing cycle by all the turbines/generators when combined will be considerably more than the power ultimately consumed by the pumps to return the highly pressurized water in a ground level tank back to the storage tank utilizing a return tank and simple water displacement.
