The basic principle is that two vertical wind turbines adjacent to each other having their propellers integrate at the center supplements the wind energy captured by each turbine. The framework system comprises of an identical lower platform and upper platform, secured firmly and precisely together with the required braces. The vertical distance between the two platforms is according to the required vertical length of each rotor/shaft. The system is supported under the lower platform in the center by a "pivotal base" and by three wheels located equidistant on the peripheral such that the framework can rotate perpendicular to the wind according to the pressure exerted by the wind vane, in a full circle, when need be. The wheels fit snugly between two circular raised tracks which keep them in a fixed radius from the "pivotal base". The vertical rotor of each turbine is set so that the distance between the two rotors permits one half of the radius of their propeller blades, more or less, to integrate at the center on rotation. The set of horizontal propeller blades of one rotor is vertically spaced such that when "stacked" there is sufficient space for the adjacent "stacked" rotor propeller blades to integrate in the vertical space between them and in the middle sector. For example, each rotor may have 4 horizontal blades, more or less, each blade having a width of 20 cm, more or less, thus each set of rotor blades has a vertical space between them of two thirds of the width of the blade, that is 60 cm, more or less. The height of the rotor of each turbine is calculated so as to make possible 4 or 5, more or less, "stacked" set of propeller blades. The length of each blade is 3 meters long, more or less and that is dependent on the proportion of the interrelated components. It is only in the central sector that integration of propeller blades occurs while the remaining circumference of the propellers is free and unhampered of movement. Each propeller blade is supported by an oblique vertical brace from the propeller to the rotor, and also by a horizontal tangential flat brace between each blade. Together the braces provide extra rigidity to the propeller system when under high wind velocity. The wind deflector apparatus consists of an aerodynamic frontal and hull bisector vertical fin assembly that is centrally set in the middle of the turbines to bisect and deflects the wind energy onto the positive power segment of each rotor while shielding and thus minimizing the negative power segment of each turbine as they are rotating.
