摘要： A system for electric power production from wind includes a glider having an airfoil, an on-board steering unit, a flight controller for controlling the steering unit, and a connection unit for a tether. The system further includes a ground station including a reel for the tether, a rotating electrical machine connected to the reel, and a ground station controller for controlling the reel and the rotating electrical machine. A master controller operates the system in at least first and second operation modes. In the first operation mode electric power is produced with the rotating electrical machine from rotation of the reel caused by reeling out the tether using a lift force generated upon exposure of the airfoil of the airborne glider to wind. In the second operation mode, the reel is driven by the rotating electrical machine, thereby reeling in the tether onto the reel.

摘要： It is about an omnidirectional generator apparatus, capable of translating the push of a fluid from any direction in the vertical, horizontal or diagonal plains to rotational movement on a unique axis. This rotational movement can be translated to electric energy by known means.

摘要： A system that maintains the relative and/or absolute geographical positions of two or more buoyant devices floating in a body of water. A plurality of formation restoring tethers are disclosed which permit the unrestricted vertical movement of networked buoyant devices, while resisting increases in their lateral separations by providing restoring forces to oppose such separations. Tensioning mechanisms incorporated into the tethers generate the resistance to the lateral separations of two or more entities by transforming such separations into an increase in the potential energy stored within such tensioning mechanisms, the potential energy of which is released in the process of restoring the original separations and/or positions of the displaced buoyant devices.

摘要： A device for a traction kite for generating electricity by means of wind force, wherein exact horizontal positioning of a traction kite or of a group of interconnected traction kites or rotating flyer wheels is made possible in that obliquely braced additional traction ropes 4 at the edges of this traction kite group permit a fixed position of the traction kite, similar to when bracing domestic tents.

摘要： A bladeless wind turbine that creates electrical energy using hydraulically connected pistons. The system may include a disk, a small piston in fluid communication with a large piston, and a crankshaft attached to the large piston. The disk transfers forces from the wind to the small piston. Hydraulic fluid then transfers the forces to the larger piston. When the disk and associated small piston have been forced to the end of their stroke by the wind, a gate in the disk is opened to reduce wind force on the disk by allowing air to travel through the disk. Consequently, the disk and associated small piston are pushed back to the beginning of the stroke by the pressure created by the large piston's weight. This process is repeated by closing the gate in the disk. A crankshaft powering an electric generator is turned by the movement of the large piston.

摘要： The exemplary embodiments herein provide a bridle for use with a rigid wing having two opposing ends, the bridle having a fixed bridle member attached to a bottom surface of the wing, a pair of connection points positioned on the fixed bridle and located at distance D vertically below the bottom surface of the wing, a rolling bridle member with a pair of opposing ends, where each opposing end is attached at one of the connection points, and a pulley with a sheave that travels along the rolling bridle member. In some embodiments, a motor is mechanically connected with the sheave. In some embodiments, the distance D is optimized for a preferred roll moment as the wing rolls through various angles.

摘要： Methods, systems, and techniques for harnessing wind energy use a tethered airfoil and a digital hydraulic pump and motor, which may optionally be a combined pump/motor. During a traction phase, a wind powered airfoil is allowed to extend a tether and a portion of the wind energy harnessed through extension of the tether is stored prior to distributing the wind energy to an electrical service. During a retraction phase, the wind energy that is stored during the traction phase is used to retract the tether. The digital hydraulic pump and motor are mechanically coupled to the tether.

摘要： The present disclosure relates to an aerial vehicle with a horizontal tailplane disposed along a bottom edge of a vertical tailfin. Namely, the aerial vehicle includes an empennage attached to the fuselage via a tail boom and a tail coupling. The empennage includes a vertical tailfin that extends below the tail coupling. The empennage also includes a tube arranged along a leading edge of the vertical tailfin and below the tail coupling of the aerial vehicle. The empennage additionally includes one or more rotating actuators and a horizontal tailplane. The horizontal tailplane is coupled to the tail via the tube and includes a continuous leading edge and a cutout. The one or more rotating actuators are configured rotate the horizontal tailplane about an axis of the tube. At least a portion of the vertical tailfin is configured to pass through the cutout.
