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： The apparatus for use of flow energy has elongated circumferential elements (18) with incident-flow surfaces (34, 35) facing the flow, which elements (8) are connected parallel to one another at intervals to form a rotating cage (1) or to form a strip, which is circumferential on a guide and in which they form crossbars, and the rotation axis or deflection axes is or are arranged transversely to the flow direction, with the elements (8) each having two incident-flow surfaces (34, 35). The two incident-flow surfaces (34, 35) may have the capability to swivel into the direction facing the wind by rotation of the elements (8) when the rotor (1) or strip is running. Outside the rotating cage (1), the apparatus may be provided with essentially radially aligned guide walls (22), and the rotor (1) and the walls (22) may be provided with a roof (24) in the form of a flat truncated cone.

摘要： Disclosed is a multiple blade wind turbine (MBWT). The MBWT includes: at least one rotor comprising two closed loop tracks positioned parallel or equidistant to one another and a plurality of airfoils interspaced within the tracks. The plurality of airfoils are connected at each end to one of said tracks and are fully rotatable with respect to said closed loop tracks. A transmission is connected to one of the tracks. The track drives the transmission and an electric generator is connected to said transmission for generating electricity. The rotors are oriented vertically or horizontally with respect to a vertical support structure that is used to support the rotors. The MBWT's design allows the electric generator(s) and transmission system to be housed relatively close to ground level. This configuration reduces the mass of the central support tower and reduces the construction and ongoing maintenance costs.

摘要： A hydrokinetic energy conversion system (HKECS) is provided, comprising design configurations suitable for efficient production of tidal or river in-stream kinetic energy into useful mechanical energy for tasks such as generating electricity or water pumping. The apparatus includes a set of blades with an airfoil cross sectional contour moving on a horizontal or vertical closed loop track, whereby the blades are propelled through the water by a net tangential lift force, rather than drag, to effectively convert the kinetic energy of flowing water to useful power.

摘要： Double blade airfoils and related systems are disclosed. The double blade design may efficiently use a minimal amount of material yet achieve exceptional aerodynamic efficiencies well above the previously understood theoretical maximum. The disclosed designs may operate at lower wind speeds than those known in the art. Furthermore, the balance of forces generated by the disclosed designs may also reduce the stress felt by the airfoils and rotor, enhancing the longevity of the system.
