摘要： The modular hydrokinetic motor device is a power generation apparatus for generating power from water flows. The power generation apparatus has a transducer from hydraulic to mechanical energy with a hydraulic side and a mechanical side. A generator is coupled to the mechanical side of the transducer. The hydraulic side of the transducer has a guiding mechanism and a series of paddles adapted to move along the guiding mechanism. The guiding mechanism has a driving path that defines a linear movement along the guiding mechanism in a downstream direction and a driven path that defines a linear movement along the guiding mechanism in an upstream direction. The driving path and the driven path are parallel paths. The apparatus is configured so that the driving path have a higher dragging coefficient than the driven path.

摘要： A device (1) for generating energy on the basis of wave motion comprises a rotatably arranged basic body (10); an elongated, rod-shaped body (20) which is connected to the basic body (10), and which has buoyancy with respect to sea water; an arm (30) which extends between the basic body (10) and the rod-shaped body (20) and interconnects these two bodies (10, 20); and a main shaft (40) which is connected to the basic body (10) for the purpose of being driven by the basic body (10). The rod-shaped body (20) is destined to be moved in and out of the water under the influence of wave motion, and of a rotary movement of the basic body (10), which performs a flywheel function during operation of the device (1). Due to this, the said rotary movement can be maintained.

摘要： The present disclosure is directed at a method and system for harnessing wind energy using a tethered airfoil. During a traction phase, wind is allowed to extend a kite tether. Wind energy that is harnessed through extension of the kite tether is mechanically stored prior to using the wind energy that is stored to generate electricity. During a retraction phase, the wind energy that is mechanically stored during the traction phase is used to retract the kite tether. Beneficially, the mechanical storage allows the kite tether to be retracted without relying on electricity from an electrical grid.

摘要： A hydrokinetic electrical generating device includes first and second wing assemblies each having axis vertical wings. First and second beam assemblies support the first or second wing assemblies. A first sliding member is slidably connected to the first beam assembly and a second sliding member is slidably connected to the second beam assembly. The axis vertical wings are rotatably connected to one of the first or second sliding members. A first sliding connector is connected to the first sliding member and a second sliding connector connected to the second sliding member. A mechanical-electrical section has first and second flywheels connected by a first or second drive belt to a generator. First and second flywheel connecting rods connect the first or second sliding connector to the first or second flywheel. A water force rotating the wings displaces the connecting rods causing flywheel and drive belt rotation thereby operating the generator.

摘要： A system for converting between fluid movement, such as wind, and mechanical rotation is disclosed. The system includes a support which is rotatable about a first axis orthogonal to the direction of fluid movement and at least one panel mounted on the support for rotation about a said axis. The panel includes a matrix of flaps (elementary panels) mounted on the panel framework for rotation about a multiple secondary axes; and retaining hardware serving to resist rotation of the said flaps during a first portion of the rotation cycle of the support and permitting the flaps to rotate freely during a second portion of said cycle. The panel provides a driving torque during said first portion of the cycle and moving freely to an orientation of minimum fluid resistance during said second portion.

摘要： Biasing unit, a spindle member, and a link mechanism of a windmill for a wind power generator vary an angle of a blade in a first stage where the angle is made nearly parallel to the wind so that the blade easily rotates in light winds, a second stage where the angle is made nearly perpendicular to the wind so that the blade easily rotates at high speed when the wind speed increases, and a third stage where the blade is pushed back from the state of being nearly perpendicular to the wind to the state of being nearly parallel to the wind so as to prevent the excessive rotation in strong winds, without electrical control being not required. Accordingly this wind power generator has an excellent starting performance and can control the excessive rotation at low cost.

摘要： In accordance with the present invention, a portable wave-swash & coastal-wind energy harvester, placed on a sea coast in swash zone captures energy contained in coastal waves and in coastal-wind through the utilization of wave turbines, wind turbines, and wave floats. Wave-float levers carrying wave floats and wave turbines, swing and maintain lower halves of wave turbines below water always. A gear system with one-way clutches transmits torque to an alternator to generate electricity. Flywheels maintain steady rotation of alternator shaft. A buoyancy chamber at the bottom produces reduction of weight of the unit when buoyancy chamber is emptied of water, and thereby enhances maneuverability of unit in water. Stabilization tanks at the top when filled with water provide extra weight and stability of the unit in its operating location. Units linked together in an energy farm combine their energy while forming a seawall-like barrier offering protection against coastal erosion.

摘要： Described is an oscillating device for generating electricity from a fluid flow, comprising at least one oscillating part, at least one support, fixed to a reference surface and connected to the oscillating part at an oscillation axis, at least one counter-balancing system connected to, and/or acting on the oscillating part, at least one adjustable profile configured to be at least partially immersed in the fluid flow and movably connected to the oscillating part. The oscillating device comprises an adjustment system configured to change the position of the adjustable profile with respect to the fluid flow between at least one position of greatest resistance and at least one position of least resistance. The invention also relates to an adjustment method for oscillating devices designed to generate electricity, according to which adjustments to the position of the adjustable profile are made as a function of certain parameters, such as the speed and/or the change in direction of the oscillation of the oscillating part, detected by a series of sensors.
