摘要:
A roof 201 has an apex 200. A wind turbine 202 is positioned above the apex 200. Air flows through the gap 204 between the apex 200 and the turbine 202. A flow optimiser 203 diverts a section of airflow close to the apex 200 into the region 205, downstream of the apex. This section of diverted airflow is turned away from the local airflow direction towards the surface of the roof 201, downstream of the apex. This reduces the boundary layer separation and turbulence downstream of the apex 200, which reduces energy loss associated with sub-optimal static pressure recovery downstream of the apex 200, and thus increases the discharge coefficient of the system.

Methods, systems, and devices are disclosed for wind power generation. In one aspect, a wind power generator includes a support base; inductors positioned over the support base in a circular array; an annulus ring track fixed to the base support and providing a circular track around which the inductors are located; an annulus ring rotor placed on the annulus ring track and engaged to rollers in the circular track so that the annulus ring rotor can rotate relative to the an annulus ring track, in which the annulus ring rotor include separate magnets to move through the circular array of inductors to cause generation of electric currents; and a wind rotor assembly coupled to the annulus ring rotor and including wind-deflecting blades that rotate with the rotor and a hollow central interior for containing a wind vortex formed from deflecting wind by the blades to convert into the electric energy.

Au moins l'un des premier et deuxième réservoirs (311, 312 ; 120) est intégré dans les fondations à la partie inférieure d'un bâtiment artificiel (301, 303 ; 200A) dont la construction est rendue nécessaire par une fonction primaire indépendante d'une fonction secondaire de production d'électricité. Le premier réservoir (315) ou le deuxième réservoir (120) peut constituer une étendue d'eau commune au voisinage du niveau du sol. Les réservoirs (311, 312, 210, 220) intégrés dans des fondations de bâtiments peuvent en particulier coopérer avec des installations de climatisation ou de chauffage des bâtiments à la base desquels ils sont construits ou de bâtiments associés.

摘要:
A prime mover that is powered by the energy of a fluid is provided. Such a prime mover may include a first fairing, a second fairing spaced apart from the first fairing to define a gap therebetween and a blade assembly mounted on a shaft that extends between the first and second fairings. The first and second fairings each have a curved peripheral edge for guiding a fluid into the gap at an increased velocity. When the fluid flows into the gap it contacts the blade assembly to thereby rotate the blade assembly about an axis that is defined by the shaft. The rotation of the blade assembly may be used to generate power in a power generator. The prime mover may be mounted on a cell phone tower and used to generate electricity for powering components of the tower and/or for providing electricity to the power grid.
摘要:
A wind turbine structure has a vertical core that supports multiple stages of rotor support frames and power generating units, each rotor support frame comprising an annular carousel rotatably located about the core and having at least two radially extending arms, and at least one pair of propeller-type rotors located respectively at distal ends of the radially extending arms. Each rotor support frame can rotate around the vertical core independently. Each rotor support frame further comprises a wind deflector.

A rotatable building structure (10) contains a vertical central core (14) for supporting suspended floor units (12) surrounding the core. An annular platform (22) extends from the core at corresponding floor units for providing accessibility to and from the central core. The floor units contain a drive mechanism (38, 40, 42) for rotational displacement. The wind load on the exterior side of each floor, and/or horizontal wind turbines that turn around the core but is a separate part of the floor itself, solar panels situated as a roof cover on top of each floor and a wind tool (46) deployable from the floor unit provides alternative wind power assist for rotating the floor units.
摘要:
There is provided a wind turbine apparatus which comprises blades having an aerofoil profile. The apparatus is arranged to start up even in light wind conditions and to act as a lift type device at higher rotational speeds. The apparatus may comprise wind deflectors to concentrate wind through the apparatus. Further, the blades may be orientated at less than 90° to a radius line which leads to improved performance. Still further, the apparatus may be arranged to heat water by means of solar energy.

An embodiment of a building may include a wind-energy-conversion system with a duct that may be a substantially vertical converging nozzle. An energy extractor may be fluidly coupled to the duct. For some embodiments, a space within the building may be part of the wind-energy-conversion system and may be fluidly coupled to the energy extractor by the duct.
