An apparatus includes a rotating pole, a first set of photovoltaic modules; and a second set of photovoltaic modules. At least one of the first set of photovoltaic modules is perpendicular to at least one of the second set of photovoltaic modules.

A high performance hybrid turbine is provided which has an impeller towards which a fluid flow of water, air, or other fluid is conveyed for rotation of the impeller around an axis of rotation. The impeller exploits the thrusts that the fluid flow exerts on the elements constituting the impeller and the thrusts generated by a certain number of airfoils provided inside the elements of the impeller. The high performance hybrid turbine, if used as a wind turbine, can operate at much higher wind speeds than conventional wind turbines.

A vertical-axis wind turbine generator includes two or more rotor assemblies, each rotor assembly having two or more wind turbine blades mounted for rotation, preferably those having a Savonius configuration. A cowling includes a nose portion forming a bifurcating wind diverter, in which the bifurcated airflow is directed in order to cause counter directional flow of the wind turbine blades. According to at least one version, the cowling further includes a cover portion that defines a venturi chamber above the rotating blades to draw air into the top of the turbine above the rotating blades and create a vacuum, thereby reducing resistance. The cowling can be part of an existing wind turbine or alternatively replace an original cowling as a retrofit.

A material (such as potassium hydroxide or ammonia) capable of reacting with ambient carbon dioxide to produce fertilizer is placed in the path of ambient air movement. Desirably the material is associated with a fabric which in turn is associated with a vane of a vertical axis wind turbine, the turbine performing useful work as well as supporting the material which produces a fertilizer. A misting system controlled by a controller may automatically apply a water mist to the material if the humidity is below a predetermined level. The fabric with produced nitrogen and/or potassium fertilizer may be placed directly into contact with soil, or shredded first, or burned to produce energy and an ash (and the ash applied to the soil). The wind turbine may have a convenient, versatile mounting system with three adjustable legs supporting a central component, and the spokes of the wind turbine may be slotted for easy assembly with vanes.

A wind power generator is disclosed. The wind power generator includes a wind rotor, a fluid coupling, and a rotary electric machine. The wind rotor is disposed to be rotatable. The fluid coupling includes an impeller receiving a torque inputted thereto from the wind rotor, and a turbine receiving the torque transmitted thereto from the impeller through a hydraulic fluid. The rotary electric machine is configured to generate electricity by the torque transmitted thereto from the turbine.

A vertical wind turbine that includes a plurality of vertical vanes which can be rotated independently of one another about a respective vane rotational axis by a motor and which are mounted on a common circular path in a rotatable manner about a vertical rotor rotational axis. A method for operating a vertical wind turbine. Angular positions are specified for vertical wind turbine vanes which are mounted in a rotatable manner about a respective vertical rotor rotational axis and which can be rotated about a respective vane rotational axis by a motor. The vertical wind turbine is operated in a particularly efficient and material-preserving manner in that the angular positions of the vanes are specified by at least one respective pitch motor which at least partly supports the respective vane.

A wind harvesting assembly for a wind turbine, having: a Venturi tube having a hollow interior having a first air pressure; an open top end having a first diameter; an open bottom end having the first diameter; a tube length spanning between the open top end and the open bottom end; and a constricted section located above the bottom end, the constricted section adapted to increase a velocity of air passing through by having a second diameter smaller than the first diameter; a plurality of vertical wind turbine blades arranged around the Venturi tube, an outlet disbursement blade assembly disposed below the bottom open end of the Venturi tube and a port fan positioned coaxially with the Venturi tube.

In this invention, some unique blades are embedded which start from the top of the glass dome, extend around it and ending up below the dome plate. All of these blades are used to slow rotation of the tower. This vertical wind turbine, while rotating the structure to see the various views and landscapes around the tower, provides the electrical power required by the penthouse from wind power by the generator. Three blades are embedded in the top of the turbine, which is the upper part of the main blades. Lower and inside the container in roof of dome, the gearbox and generator are located to which harnessed energy by blades is transferred.

A vertical wind turbine includes a shroud for directing vehicle-created wind towards the turbine blades, which are oriented in response to wind direction.

The Vertical Tilting Blade Turbine Windmill device is for capturing kinetic energy from the wind and is comprised of a vertical shaft having a central hub connectively attached, the central hub having a plurality of wind capture arms comprising a rotating wind capture blade having a capture surface and a slicing edge that are rotated wherein the wind capture blades are rotated between a blade mode to capture the wind and a knife mode to pass with less drag resistance through the air/wind thereby enabling an increase in the ability to capture more of the energy available in an on-coming wind stream.
