摘要： A vertical-axis renewable-power generator is an apparatus that is used to efficiently generate power in various weather conditions using renewable energy sources. The apparatus includes a vertically-oriented foil and a fluid turbine. The foil is designed to generate areas of relative high fluid velocity and low pressure on one side and relative lower fluid velocity and higher pressure on the opposite side. The foil is also self-directing so that the foil can follow the direction of the fluid flow. The fluid turbine is integrated into the foil so that the fluid turbine can be rotated by the high-speed fluid flow. The rotation of the fluid turbine can be used to generate electricity. The apparatus conforms to the Bernoulli's principle that is proven to increase the speed of the fluid flow over the foil, which is used to increase the speed of the fluid flow impacting the fluid turbine.

摘要： Provided is a steam turbine in which, among a plurality of stages thereof, a stage that is disposed furthest upstream is a speed-adjusting stage, at least one stage that is disposed downstream of the speed-adjusting stage is a medium-pressure stage, and at least one stage that is disposed downstream of the medium-pressure stage is a low-pressure stage. The speed-adjusting stage is an impulse stage. The medium-pressure stage is a medium reaction degree impulse stage in which the degree of reaction is a medium degree of reaction of 10-40%. The low-pressure stage is a reaction stage having a higher degree of reaction than the medium-pressure stage.

摘要： A barge generator adapted to generate electrical power from surface currents of a body of water. The barge generator has a plurality of hull portions that form one or more tunnels along the length of the vessel. Hydrodynamic screws are received in the tunnels and coupled to an electrical generator such that water currents communicated through the tunnel impart rotational movement of the screw. A deployable curtain is extensible to funnel the currents towards the barge generator to increase the volume and velocity of water carried through the tunnel.

摘要： A regulatable air-flow acceleration unit for wind energy conversion equipment is presented. The novel regulatable air-flow acceleration unit includes a wind acceleration channel containing pressure-limiting devices arranged in a novel sequential way, protruding from above and from below into the wind acceleration channel which creates a variable degree of restriction. The pressure-limiting devices contain a regulation valve having a rotation axle connected to a tilting body that can be positioned in the radial direction in the case of air-flow acceleration units arranged in a circular cylinder section shape used in vertical axle turbines allowing for smoother and finer regulation during the movement of the tilting bodies.

摘要： A wind driven electricity generator may have a tower with a set of stationary airfoils mounted thereon. Each airfoil may have a slot on a low pressure side of the airfoil. Air flow may through the slot relative to an inside of the airfoil. Air flowing through the airfoil may flow through the tower. The air flowing through the tower may turn a rotor (or propeller). The rotor may turn an electrical generator to generate electricity. Each airfoil may have a slot on a high pressure side. Air flowing through the slot on the high pressure side may turn the rotor.
