The present invention is directed to a system for producing energy via use of gravity. The system is for generating energy, and in particular electrical energy, by utilizing the abundant force of gravity that exists and then integrating such a force into a system design of energy power generation by converting the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again, by using the system's autonomous methodology of fluid recycling to produce electric power generation in the process.

Refrigeration cycle ejector power generator makes use of refrigerant in a refrigeration cycle to feed an ejector or injector within the refrigeration cycle causing the ejector to fire refrigerant at extremely high pressures and velocities into a turbine fan or blade that is sealed inside the refrigeration system and is connected to a generator in order to generate electricity. Refrigeration cycle ejector power generator comprises: a condenser, an expansion valve, an evaporator, a compressor, an ejector valve, a first ejector, a turbine, and a controller or computer. Refrigeration cycle ejector power generator is a refrigeration cycle with at least one ejector positioned in the refrigeration cycle that emits refrigerant at a high pressure and high velocity that is directed at a turbine, causing it to rotate, where this rotational energy may be used to turn a generator, thereby generating electricity.

A pressure of a working compressed fluid is released into a liquid circuit to drive a turbine for energy generation, comprising a compressor and a primary tank of high pressure, a first main tank of liquid and a second main tank of liquid, an auxiliary tank of liquid, a turbine of liquid located between the first and the second main tanks, and at a lower level than that of the bottom of the main and second and auxiliary tank, to ensure that the pressure inside the tanks forces the liquid in the proper direction through the turbine, a network of pipelines with their respective valves, such as inlet valves, outlet valves, control valves or pressure-regulating valves, as well as ventilation valves; where the operation is performed in short cycles and at a constant pressure by means of a control system that acts on at least one pressure-regulating valve.

A method and apparatus using atmospheric pressure and vacuum force to generate electricity performs coordinated operations of normally open (NO) valves and normally closed (NC) valves to repeatedly push water through an upward pipeline to a first vacuum chamber and let the water flow down by gravity to strike the water wheel of a hydraulic power generator installed in a second vacuum chamber to generate electricity. Specifically, two NC solenoid valves are included to regulate the water flow inside the apparatus, whereas a third NC solenoid valve is included to enable or disable the atmosphere's interaction with the air pressure cylinder of the apparatus in regulating the water flow in each power generation cycle. The method and the apparatus is not affected by local climates or geographical locations and may be installed and applied almost anywhere.

The invention relates to a hydraulic device that uses gravity and buoyancy forces, in which during a rotation of the assembly, movable masses (M1, . . . , Mn) are displaced by means of a force acting on the masses that counteracts the weight force in such a way that said masses contribute to the rotational movement.

An air-driven generator for generating electric power from movement of a working fluid. Upper ends of buoyancy conduits are in fluidic communication with an upper end of a gravitational distribution conduit, and a lower end of the gravitational distribution conduit is in fluidic communication with lower ends of the buoyancy conduits. An air injection system injects air into the buoyancy conduits. A closed fluid loop is formed with working fluid flowing from the gravitational distribution conduit driving a fluid turbine system that is interposed between the lower ends of the gravitational distribution conduit and the buoyancy conduits. Flow of working fluid can be induced by an injection of air into working fluid disposed in the buoyancy conduits to achieve a generation of power by actuation of the fluid turbine system. An upper chamber can remove entrained air. A Rankin Cycle Generator can receive and be actuated by exhausted air.

Low cost Pumped Hydro Energy Storage (PHES) sites have already been exploited; new PHES sites now cost $2 million per MW. A very large number of sites exist, not only on the coast but all over the land mass of all continents, that have an altitude difference of 100 m between two levels, where 1 to 5 million tonnes of solid can solid can safely be stored at both high and low levels. Thus solids like sand, crushed rock and soil can be used to provide virtually unlimited gravitational energy storage. Pumping slurry of solid/water to an upper level creates energy storage. When required, solid in slurry form flows down to the lower level, through a turbine. The turbine runs a generator releasing electrical energy. A relatively small amount water is recycled indefinitely create more slurry and transfer solid up/down as needed making solid pumped hydro feasible even in deserts.

This invention relates to a submersible hydroelectric generator apparatus (1) and a method of evacuating water from such an apparatus. The method of evacuating water from a submersible hydroelectric generator apparatus (1) comprising the steps of pressurizing a fluid supply in the submersible hydroelectric generator apparatus using the water flowing into the apparatus and thereafter using the thus-pressurized fluid supply to evacuate the water from the apparatus. Additional pressurized fluid can be supplied to provide a pressurized fluid supply with sufficient pressure to expel the water from the apparatus. The apparatus (1) can be used in a grid connected electricity generating system or indeed in a smaller scale implementation such as in a single building or group of buildings to provide electricity to those buildings. The invention overcomes problems with prior art devices by evacuating water from the apparatus in an efficient manner.
