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.

摘要： This invention discloses an improved wind turbine suitable for mounting without a wind turbine tower. The wind turbine is based on a rotor with appropriately selected blades. A nozzle and diffuser in the wind flow increase the amount of wind energy available to the rotor. One or more wind turbines can be grouped together in a common housing. The lack of a wind turbine tower and the general compact design allows the wind turbine to be used in close proximity to or on buildings.

摘要： The invention is designed for manned and drone vehicles and utilizes the console and drive train area of an automobile. The invention relates to in-transit conservation of energy via the aerodynamic design improvement, and the in-transit generation of energy via the console wind power generation system. It relates to the cooling of rear electric motors and the thrusting of the vehicle by sending power back to the wind generation power system and includes combustion at a point past or behind the wind generator motor area. Wind is coursed completely through the vehicle via the opening at the front grill area, through the traditional console and drive train area, through a cylindrical, concentric, or other bladed generator or generators which charge the power grid, battery, or drive motors, then out through opening at the back of the vehicle. Power can also be sent back to the generator where it operates as a motor, powering the blades to thrust the vehicle forward.

摘要： The Wind Energy Amplifier, with one-sheet hyperboloid form, amplifies the wind speed exerted on the wind system propeller, by increasing the pressure and speed of naturally occurring wind. It is possible to increase the speed of wind, its force and kinetic energy, by continuously channeling a wind flow passing through a “one-sheet hyperboloid” aerodynamic structure, where the wind flow inflow surface is larger than the outflow surface for the same wind flow.Benefits associated with using the Wind Energy Amplifier extend to any wind system intended to harness wind kinetic energy and subsequently convert it into any other type of energy, without being limited or restricted to power generation.By using the One-Sheet Hyperboloid Wind Energy Amplifier, wind systems can increase wind speed, and the power and performance of a wind system, given a predetermined kinetic wind energy, enabling an increase in the power generated by any wind system.

摘要： The invention relates to a ducted wind turbine having a turbine rotor assembly which extracts kinetic energy from air flowing there past. The rotor assembly includes a plurality of rotor blades having rotor tips at their outermost ends which define a rotor tip sweep circumference. A duct assembly at least partially surrounds said rotor tip sweep circumference and a base platform supports the ducted wind turbine. The duct assembly is mounted on the base platform by way of a weathervane bearing arrangement such that the duct assembly may weathervane around the turbine rotor assembly in response to changes in wind direction. A semi-submersible support platform, wave energy capture apparatus, torsional bearing mechanism and a latticework wind turbine tower associated with the ducted wind turbine are also provided.

摘要： The invention relates to wind power and allows effectively convert 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. Moreover, the area of wind flow capturing by lateral surface of this system, depending on the number of stages, several times exceeds the area of wind flow capturing by base of first confusor from side of wind flow. In proposed installation for increase of output power, three parameters are used at relatively small sizes of airscrew. In this case, the wind flow, which is captured by working part of the wind turbine, is compressed by all sides, increasing the speed of the directed airflow, acting on the airscrew. All turbine stages, except the last stage, represent the not full Venturi tubes consisting of a confusors and virtual necks. The last stage represents the classical Venturi tube, consisting of confusor, neck and diffusers. The airscrew is located within the neck of the Venturi tube. Turbine is equipped with a weather vane and means of protection from destruction during hurricane wind.
