摘要： A wind turbine assembly for covering wind energy into electrical energy includes a housing that is positioned adjacent to a roadway. An intake chute is integrated into the housing and the intake chute is oriented to face oncoming traffic on the roadway thereby facilitating the intake chute to direct wind produced by the oncoming traffic into the housing. A wind turbine is rotatably disposed within the intake chute such that the wind turbine is rotated by the wind produced by the oncoming traffic. A generator is positioned in the housing and the generator is in mechanical communication with the wind turbine. The generator is rotated when the wind turbine rotates to convert wind energy into electrical energy.

摘要： The Wind Wall is a solid structure composed of one or more Wind Cells, arranged adjacently, one next to the other, in an orderly and symmetrical way, in such a way that as a whole they form a continuous structure of Wind Cells, sustainable by itself and modular along the three physical dimensions, where each Wind Cell has an inlet opening and an outlet opening, where the internal surface comprised from the inlet opening to the outlet opening has the shape of an extrados (upper face) blade profile in revolution, and where the inlet opening and the outlet opening are of equal or substantially equal dimensions.
The Wind Cell, being the constructive component of the Wind Wall, is an aerodynamic structure specially designed to increase the wind speed within a critical space and, therefore, increase the wind power available to be used by the rotor of a Wind Turbine. The increase in wind speed is achieved through the deliberate creation of environments with high pressure differentials and, at the same time, environments dedicated to maintaining laminar wind flow and mitigating turbulent flow.
The Wind Wall is by itself a new generation of Wind Systems based not only on the aerodynamic efficiency of the Wind Turbine, but also on the aerodynamic efficiency of the structure and environment surrounding the Wind Turbine. In this sense, the new generation of Wind Systems, based on the application of the Wind Wall, will be able to increase the wind speed and, therefore, increase the density of the underlying power, given the same wind resource available in nature, allowing this way a general increase in the capacity of generating electric power.

摘要： An encased wind turbine has a casing, rotationally symmetrical in relation to the longitudinal axis and has the cross-section of an airfoil. The radially inner upper side delimits a flow channel. A guide element is rotationally symmetrical in relation to the longitudinal axis projects by part of its length, contrary to the direction of flow, over the casing. The propeller drives a generator, arranged in the housing, for generating electrical energy. The propeller viewed in the direction of flow, is located at least approximately at the guide-element trailing edge. Impinged on by the main flow of the wind, while a bypass flow, owing to the airfoil profile, generates a negative pressure downstream from the guide element and thus accelerates the main flow, is generated between the casing and the guide element. The propeller may be located downstream from the guide element and arranged to be adjustable in its longitudinal position.

摘要： A turbine is provided which effectively converts the kinetic energy of the wind, after its (wind) accelerating, to electrical power. The multi-stage wind turbine, which allows multiple accelerate directed air flow (wind), even of most minimal speed, up to strong wind and convert it's energy into electrical power, is proposed. It is achieved due to modularity of installation, where the wind is accelerated within each module due to the processes of capturing the initial wind flow, injection-ejection and aerodynamic Coanda effect as well, by virtual necks and conical confusors nested one into another. The system of truncated cones and virtual necks with optimum aerodynamic sizes provides the capture of the airflow not only perpendicular to the base of these cones, but also from lateral sides of these cones.

摘要： An apparatus to produce electricity from several renewable energy sources. The device collects wind into a duct, adds energy to the collected wind by adding heat from the sun and building exhaust, and produces electricity via a generator therefrom. The wind capture unit includes a plurality of faces that face all compass directions to avoid having to adjust the device upon shifts in wind direction and speed. The duct includes a tapered portion that serves to increase a speed of inflow air prior to impinging upon a turbofan generator. The device can be mounted on a top of a building and receive building exhaust while supplying the building with electricity. The result is a higher efficiency device with pleasing aesthetics.

摘要： A wind control blade (31) of a wind guide (30) of the present invention forms a 20° wind control blade lateral curved surface gradient angle (32), a 30° wind control blade longitudinal spiral twist angle (33), a 180° wing control blade alignment angle (34), and a 15° wind control blade rear gradient angle (35). In addition, a turbine blade (41) forms a 30° turbine blade lateral curved surface gradient angle (42), a 40° turbine blade longitudinal spiral twist angle (43), and a 120° turbine blade alignment angle (44). The 20° wind control blade lateral curved surface gradient angle (32) and the 30° wind control blade longitudinal spiral twist angle (33) of the wind control blade (31) have more gradual and wider incidence angles than the 30° turbine blade lateral curved surface gradient angle (42) and the 40° turbine blade longitudinal spiral twist angle (43) of the turbine blade (41). Accordingly, since more wind enters into the central direction of the inner side of the turbine blade (41) and a primary whirlwind is generated, much higher acceleration can be obtained.
