The present invention relates to a waterpower stream amplifier device primarily comprised of a body with an outer surface further comprised of at least one exterior protrusion and an interior surface further comprised of at least one angular flow director. The device can be placed/combined with the rotor of an underwater hydroelectric turbine in order to concentrate and multiple the energy of the water stream entering the turbine. The at least one angular flower director of the interior surface, the at least one exterior protrusions and at least one longitudinal opening of the outer surface allows water to enter the interior surface of the body from all directions. As a result, a rotating water vortex is created within the interior surface as the water travels from the first end towards the second end.

An apparatus (1) for generating power is provided. The apparatus comprises: at least one pocket (2a-h) for collecting inlet gas which rises through a liquid in which the at least one pocket may be located; an output rotor (4); and a greenhouse gas scavenger (6) for removing greenhouse gas from an inlet gas; the apparatus being configured so that collection of inlet gas causes movement of the pocket, the pocket being coupled to the output rotor so that movement of the pocket causes rotation of the output rotor. A method is also provided.

A turbine having a rotor assembly with substantially cylindrical blades. A scoop may be used to direct a fluid flow into the turbine, thereby causing a pushing force and/or a suction force to be exerted on at least some of the cylindrical blades. Accordingly, the rotor assembly may rotate within the turbine. In an example, the rotor assembly may include a plurality of magnets, which may cause a magnetic field to fluctuate. Copper discs on the turbine enclosure may be used to generate electricity based on the changing magnetic field. In another example, the turbine enclosure may have one or more openings, which may generate a suction or pressure force as the rotor assembly rotates.

A compressor rotor assembly including a plurality of rotor disks axially spaced from each other, each rotor disk extending radially from an inner end to an outer end. Also included is a spacer extending axially from each rotor disk to engage an adjacent spacer extending from an adjacent rotor disk, the spacer and adjacent spacer disposed proximate the outer end of the respective rotor disks, the spacers forming an outer backbone of the compressor rotor assembly. Further included is an inner backbone of the compressor rotor assembly, the inner backbone comprising a plurality of backbone segments, each of the backbone segments extending axially from each rotor disk to engage an adjacent backbone segment extending from an adjacent rotor disk, the backbone segment and the adjacent backbone segment disposed proximate the inner end of the respective rotor disks.

A fluid mass movement electrical energy generation device and system may comprise a modular and scalable array of stationary tube-shaped modules containing small rotating turbines. Tube-shaped modules may be easily installed by anyone, almost anywhere fluid mass flow is present (including many locations not suited to conventional wind turbines) and may efficiently, safely and quietly capture energy from turbulent and inconsistent fluid flow patterns.

An electrical energy generating device (1) to transform kinetic energy of fluid passing through a pipe into electrical energy, the device may include a flow management unit (2) having a first housing (20) enclosing a plurality of tubes and a first gasket (27); a generating unit (3) having a second housing (30) with a plurality of coils (37) embedded within the second housing (30), a rotor rotatable within the second housing (30); and a connector (4) connecting the flow management unit (2) to the generating unit (3).

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.

The hydro turbine of the invention consists of a housing, which represents a stator part of hydro turbine, or a stator (S), and a rotor (R) that is assembled on the stator (S) through its axis so as to enable its rotation. The rotor (R) is designed as an axially symmetric body with flat lateral surfaces with a circular cross-section. The circular cross-section from both outer ends, that is from both flat lateral surfaces with a circular cross-section, decreases equally and continuously towards the middle, so that the rotor (R) has a narrowest cross-section in the middle. The decrease of the circular cross-section from both outer ends of the rotor (R) towards the central part of the rotor (R) is carried out such that the shape of the rotor (R) body in the longitudinal cross-section, that is, along the axis of the rotor (R), follows the shape of a parabolic curve or a sinusoidal curve. The rotor (R) has over its entire surface, in the longitudinal direction, that is along its axis, curved grooves (U). This kind of design of the hydro turbine enables that the water flows through the grooves (U) towards the middle part of the rotor (R), where it flows out and transfers all the momentum to the rotor (R), so that the hydro turbine can generate the torque (MR) even with small and variable flows.

An energy system including a turbine wheel totally submerge including a rotary element and a wheel mounting enclosure. The wheel mounting enclosure including a cavity where a rotary element rest on said mounting enclosure exposing the upper end to the flowing body of fluid it is submerged. The wheel mounting enclosure comprising several configurations such as a tapered base for increasing the incident flow velocity.

A rotor reinforcing device to reinforce turbine rotor comprises a center connecting device which is fixed on a rotor hub, blade reinforcing members which are connected to the center connecting device and corresponding rotor blade, and guide structures which are configured to guide the blade reinforcing members to rotate around a longitudinal axis of the rotor blade. The rotor reinforcing device may be used to reinforce a rotor, a rotor-based wind turbine, a rotor-based ocean current turbine, a rotor-based tidal turbine and a rotor-based power generator.
