A confuser 22 with blades 23 is mounted on the lower base 2, and a diffuser 9 is mounted above the stator 1. A lower disc 10 of the diffuser is rigidly attached to an upper part 11 of the diffuser that serves as the upper base 3 of the stator. Lower 19 and upper 16 half-axles of rotation of the rotor are installed in upper 21 and lower 17 supports, respectively. A rotor body 7 is made in the form of a hollow truncated cone tapering upward having a curvilinear surface. Rotor blades 8 have a curvilinear surface, preferably of hyperbolic shape, and are installed on an outer surface of the rotor body 7. Upper 13 and lower 14 impellers with curvilinear blades 15 and 20 are mounted inside the rotor body. A rotor fan 25 is additionally installed inside a cavity 24 of the lower disc 10 of the diffuser 9. The blades of the fan are wrapped around the upper part of the outer surface of the rotor body 7. Spacing of the blades of the upper impeller 13 is chosen to be greater than a blade spacing of the fan 25.

A rotor assembly comprises a rotor having a plurality of blades and an axis about which the rotor rotates, each blade being spaced from the axis of the rotor such that there is a gap between the axis and an inner edge of each blade through which fluid can flow, and inner and outer edges of each blade lying in and defining a blade plane and each blade being offset from the axis of the rotor such that the axis does not lie in the blade plane; a casing partially surrounding the rotor, the casing having a first opening to permit a fluid flow into or out of the casing in a direction generally perpendicular to the rotor axis; and a second opening at an axial end of the casing to permit a fluid flow into or out of the casing in a direction generally parallel to the rotor axis.

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.

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.
