摘要： A power converter having a boosting mechanism with a multi-shaft vertically stepped turbine includes: a shaft sleeve, a water inlet end base, an outer sleeve, a plurality of first stepped turbine units, a plurality of first shaft rods, a plurality of second stepped turbine units, a plurality of second shaft rods and a third shaft rod. The first stepped turbine unit is located above the second stepped turbine unit. The second stepped turbine units and the first stepped turbine units rotate in opposite directions. During a drainage process, water flows move in opposite directions and collide with each other to increase a water pressure. Due to the increase in the water pressure, rotational speeds of the first stepped turbine units and the second stepped turbine units increase, and rotational speeds of the first shaft rods and the second shaft rods correspondingly increase.

摘要： A water power plant for the generation of electric current from a flowing medium by means of a turbine, which includes a housing around which the flow passes on an outer side, a stator of an electric generator which operates in a low-speed mode, and a rotor of the generator, which is rotatably mounted relative to the stator. The rotor includes a rotor ring with an annular surface and, starting from the rotor ring, an arrangement of inwardly extending turbine blades, thereby defining a free-standing axis of rotation. The housing defines an inlet portion with a first front-side cutting edge which delimits a circular inlet opening, from which extends an inlet-side guide surface to the rotor, and an outlet portion with an outlet opening, between which a flow path passing the rotor ring can be formed. It is provided that the inlet opening has a free inlet cross-section which is maximally as large as a cross-sectional area delimited by the rotor ring.

摘要： Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.

摘要： The invention disclosed herein comprises a system focusing water current into a relatively smaller diameter lumen, imparting vortical movement to the current, and directing the water vortex through an even smaller diameter lumen en route to turbine blades having long curved blades rotatable along an axis parallel with the lumen. Rotation of the turbine blades turns gearing interfacing with the circumference of the turbine assembly, to rotate a drive shaft connected to a generator.

摘要： An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.

摘要： A power generator assembly for using kinetic energy from a flowing fluid to generate power. The power generator assembly includes a blade assembly and a generator. The blade assembly has a head end for facing oncoming flowing fluid, a tail end spaced from the head end for facing in the direction of flow of the fluid, and a rotational axis extending between the head end and the tail end. The blade assembly includes a blade arrangement which is arranged in generally helical fashion about the rotational axis, and at least one mounting formation connected to the blade arrangement. Each mounting formation is adapted to permit mounting of the blade assembly for rotation about its rotational axis, so that in use fluid flowing past the power generator assembly interacts with the blade arrangement to rotate the blade assembly about its rotational axis. The generator is drivingly connected to the blade assembly for generating power in response to rotation of the blade assembly.
