The present invention relates generally to facilities and systems capable of initiating and maintaining vertical flow, upward, within an extended-length water column by inducing changes in density throughout the column. Specifically, the induced (vertical) flow of water within an extended water column that is the present invention is accomplished through fluid aeration, with ambient air, which is directed toward producing ascending water flow rates sufficient to generate hydraulic pressure and hydraulic powered energy, through generated radial force in hydraulic turbines. It is another goal of this invention to utilize air infused water, derived from high-density and low depths, to create said vertical flow and induce turbine actuation through said unaltered, recyclable mediums—air and water—resulting in electrical power generation and desalination.

A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end comprises a radially-extending structure that axially blocks the flow of the fluid through the first axial end. The second axial end does not comprise any structure that axially blocks the flow of the fluid through the second axial end.

An underwater turbo-generator unit for producing electrical power has a pressure-resistant shell that defines a sealed internal chamber. At least one water inlet extends through the shell to effect fluid communication between the chamber and a body of water surrounding the shell. A turbine is supported within the chamber to turn on a spin axis in response to admission of a flow of water into the chamber via the or each water inlet. The shell is arranged to maintain a gas-tilled space within the chamber, facilitating the use of a Pelton turbine that turns about a vertical spin axis. The or each water inlet communicates with at least one tubular penstock structure that can be supported by the unit outside the shell. The chamber communicates with, and drains water into, a fluid storage volume such as a pipeline positioned at a level beneath the chamber.

The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The present submersible water lifting assembly can comprise a High Pressure Recovery Turbine Pump (7/7A) that utilizes under water arrangements of an unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of an existing water injection system; eliminating the requirement of diesel engine driven pump, for the lifting the water. It avoids fire risk on the safety system itself, even under the conditions of a large fire, unlike that of the prior art.

In a general aspect, a system can include a reactor for combusting fuel and producing high-temperature, high-pressure liquid as a byproduct, and at least one vessel defining a cavity to be partially filled with water, with an air pocket within the cavity above the water. The system can further include respective valves to control admission of liquid from the reactor into the air pocket when the air pocket has a pressure lower than an operating pressure of the reactor, and to control emission of the water from the at least one vessel through of the vessel after the water in the at least one vessel has been pressurized by the liquid from the reactor. The system can also include a hydroelectric drive system for receiving water emitted from the cavity, and for converting energy in the received water into electrical energy.

Fuel mixed in water is combusted in a reactor having an internal operating pressure and temperature greater than 3200 psi and greater than 374° C., where the combustion of the fuel is exothermic. Air and fuel are pressurized for introduction into the reactor to a pressure greater than the internal operating pressure using energy generated from the combustion of the fuel, and the pressurized air and the pressurized fuel are injected into the reactor. Pressurized water from the reactor is injected into a drive water column that is partially filled with water to increase a pressure of the drive water column, and water at a temperature less than 100° C. is injected into the reactor to replace water from the reactor that is injected into the drive water column. Pressurized water from the drive water column is used to drive a hydroelectric drive system to produce electrical power.
