Systems and methods are presented for deploying and using a floating platform using articulated spar legs used as a type of hull, each of the spar legs attached to the floating platform by an articulated connection. Each of the articulated spar legs being moveable from a horizontal to a vertical position, horizontal for transport and vertical for deployment of the floating platform. The articulated spar legs serve to support the floating position of the floating platform. The articulated spar legs are moved from horizontal to vertical position by controlling ballast imposed upon or within spar legs. Each of the articulated spar legs are moveable from a vertical to a horizontal position with a ballast changing method. Systems and methods are presented for extracting natural renewable energy from the environment surrounding the floating platform with energy capture devices modularly affixed to the platform and energy capture devices incorporated into the articulated spar legs.

A flow channel adjusting device comprises a flow channel having an inlet and a nozzle outlet corresponding to a water turbine machine, and an adjusting device for adjusting opening dimension of the nozzle outlet, comprising a driving unit, a pivoting part, and a following part. The pivoting part has a first side rotatably coupled to a first rotating element, and is driven to rotate by the driving unit for adjusting the opening dimension of the nozzle outlet. The following part has a third side rotatably coupled to a second side of the pivoting part, and a fourth side rotatably coupled to a second rotating element which translates along a second axis perpendicular to the first axis when the pivoting part is driven to rotate. The flow channel adjusting device could be utilized in water turbine machine and generator using the water turbine for adjusting amount of water flow.

The present invention provides an improved system for generating electrical energy from air hydropower. The system includes a series arrangement of more than one vessel where each of the vessel is cylindrical in shape at center, a dome shaped structure at top and a narrow conical structure at bottom, a mechanical drive machine and a fulcrum assembly having an effort arm and a resistance arm resting on a static support, an injection pumping system which includes an injection pump which is separated into two compartment by the piston plate, a Y shaped penstock connected at the narrow conical structure at one end and formed from more than one narrow piping merging into a single pipe and a pen stock jet placed over the penstock, here the jet is injected with air bubbles which pushes the water from the penstock at high velocity over a Pelton wheel of a Pelton turbine which in turn moves a turbine shaft to generate electricity.

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.

The invention regards an asymmetric submerged air intake in a surface of a structure, wherein the air intake includes a submerged ramp extending from the surface. The ramp has a front end, a rear end, a ramp floor and two ramp side walls. The ramp floor is inclined with respect to the surface. At the rear end an entrance to an internal duct of the structure is provided. It is provided that one of the ramp side walls is a straight wall extending straight in the longitudinal direction of the ramp and that the other of the ramp side walls is a curved wall that diverges from the straight wall along the length of the ramp.

The invention relates to a method for designing and fabricating bucket turbines with calibrated jets characterised in that the skeletons of the turbines displayed on the screen allow them to be designed and then fabricated in any dimensions, any materials and any quantities, and they are built with blades designed according to the so-called five-parameter arithmetic principle, the skeleton of the turbine is displayed on the screen by means of virtual neutral fibres which are subsequently covered with a material, the turbines being contained, over the entire length thereof, in a circular envelope, which is in principle slightly rounded and has a diameter that varies over the length thereof according to the contents of the envelope, and the length of said single-component envelope is shown on a drawing and divided into four zones intersected by temporary virtual discs which each separate the zones according to the functions carried out in these areas, the front edge of said envelope being very sharp or, on demand, provided with a flange Br for allowing connection to installations, the four zones comprising:

a first zone for (1) for injecting the fluid, which is an empty space or a space containing valves or inducers, of the corkscrew type, which optionally cause a pre-rotation of the fluid which enters a second zone (2), a pointed shield pushing the flow of fluid away from the centre on arrival, and directing it away towards the second zone (2), the second zone (2) where the rotation of the fluid is created in channels that wind in spirals and open up at the rear of the second zone (2), rotating the fluid, a third zone (3) containing the rotating wheel provided with buckets with calibrated jets that harness the energy supplied by the jets of fluid leaving the second zone (2), and a fourth zone (4) containing a housing attached to the stationary casing of the turbine and placed after the rotating wheel, said housing containing channels that orient the fluid towards the outlet at the rear of the turbine, and the fluid is guided, as soon as it reaches the second zone (2), by channels contained in tubes that are arranged in continuity face to face, over the entire length of the turbine.
