EXAMPLES OF PREFERABLE EMBODIMENTS

(15) As it can be seen from FIG. 1A to FIG. 5, the vertical wind turbine system comprises a vertical wind turbine 1. The turbine 1 comprises a vertical axis, on which rotor 3 with blades 4 is installed, which are suitable as captors of fluid flow. Turbine system comprises a frontal fluid flow diverter 5 for diverting of the main fluid flow X and a cover 6 for covering of the upper part of the turbine 1. Characteristic of the turbine system is that it further comprises a rear fluid flow diverter 10 for the capture of fluid flow 102 running above the cover 6 to divert it to the wind turbine 1, creating a secondary fluid flow Y. Thus, the secondary fluid flow Y is created, which moves counter to the main fluid flow X, as well as counter to side fluid flow 101. In the indicated variant, air is used as the fluid.

(16) A vertical turbine system is illustrated in FIG. 6, FIG. 10 and FIG. 12, characterized in that system includes the single turbine 1 and a second, parallel, turbine 11. The presented system of vertical turbines comprises two paired vertical turbines 1, 11. Each turbine 1, 11 contains a vertical axis 2, onto which rotor 3 with blades 4 is installed, which are suitable for the capture of fluid flow. The system of turbines comprises a frontal fluid flow diverter 5 for diverting of the main fluid flow X, al id cover 6 for covering of the upper part of the turbines 1, 11. Additionally, the system of turbines comprises a rear fluid flow diverter 10 for the capture of fluid flow 102 running above the cover 6 and its diverting to the turbines 1, 11, creating a secondary fluid flow Y. Thus, the secondary fluid flow Y is created, which moves parallel to the main fluid flow X as well as parallel to the side fluid flow 101.

(17) The frontal fluid flow diverter 5 is situated on the frontal part of both turbines 1, 11 and partly covers each of the turbines 1, 11. Thus, the field between the turbine axes 2 is covered. Remaining uncovered are blades 4 of both turbines 1, 11 situated on the outer edges of both turbines, which are influenced by the side fluid flow 101. Frontal fluid flow diverter 5 is configured so as to divide the indicated main fluid flow X into several fluid flows: into two proportional side fluid flows 101, fluid flow 102 running above the cover 6, and fluid flow 103 running underneath.

(18) System of vertical turbines can be supplemented with additional covers 501 and protrusions 12, as it can be seen in FIG. 7B. In FIG. 7A, a system of vertical turbines is illustrated, which is devoid of covers in its lower part. An embodiment is possible (FIG. 7B), in which the previously described solution is supplemented with protrusion 12. The indicated protrusion extends to the axes 2 of the turbines 1, 11, covering a part of the lower parts of the system. The system is further furnished with a lower cover 502 of the fluid flow diverter 5, which partly covers the lower part of the system as well. Besides, there are lower side walls 501 installed on the sides of the lower cover 502.

(19) In FIG. 8 and FIG. 9, a system of vertical turbines is illustrated, in which the frontal fluid flow diverter 5 is further protruded downwards, creating a different circulation of fluid flow in the lower part of the system.
