An electric transportation means comprising a wind generator having a horizontal axis, said wind generator further comprising: - an air conveyor, having a cylindrical shape that is empty inside, having oval-shaped nozzles (104a, 104b,...) on the outer surface; - a horizontal wind turbine, comprising a rotary group of wind blades (112a, 112b,...) fixed to a union ogive; - a transmission axis, being rotating and horizontal, where said turbine is installed with its respective ogive placed at the front part of said axis and where an electric generator is installed at the rear part of said axis, through a rotary element of said electric generator, so that a rotation of turbine is transmitted, through a rotation of axis, to the rotary element of the electric generator; - said electric generator, comprising said rotary element and a fixed element, that is connected to the wind turbine through the transmission axis; the electric generator is further connected, by using electric cables, to some external electric accumulators; - at least two ball bearings (108, 111) anchoring, through connection elements, said rotary transmission axis together either with the wind turbine and the electric generator, in a stable position inside said air conveyor, at the same time allowing the rotary motion of said rotating axis on itself; - a cover closing the rear part of said air conveyor; - at least two supporting elements (106, 110) placed on the outer surface of said air conveyor, in order to achieve an anchorage of the wind generator to the transportation means on which it is installed, so that an air flow coming from the front part of said wind generator, having impact on said blades (112a, 112b,...), forces said transmission axis to a rotary motion and therefore forces the rotary element of the electric generator to a rotary motion, generating therefore electric energy that can be immediately transmitted to an electric engine and/or other devices belonging to the transportation means, otherwise the electric energy can be saved into said accumulators, characterized in that: - said wind blades (112a, 112b,...) are bent, shaped and welded to said ogive, and they have a helical convex shape with the external profile inclined towards the inside of the turbine. - an air conveyor, having a cylindrical shape that is empty inside, having oval-shaped nozzles (104a, 104b,...) on the outer surface; - a horizontal wind turbine, comprising a rotary group of wind blades (112a, 112b,...) fixed to a union ogive; - a transmission axis, being rotating and horizontal, where said turbine is installed with its respective ogive placed at the front part of said axis and where an electric generator is installed at the rear part of said axis, through a rotary element of said electric generator, so that a rotation of turbine is transmitted, through a rotation of axis, to the rotary element of the electric generator; - said electric generator, comprising said rotary element and a fixed element, that is connected to the wind turbine through the transmission axis; the electric generator is further connected, by using electric cables, to some external electric accumulators; - at least two ball bearings (108, 111) anchoring, through connection elements, said rotary transmission axis together either with the wind turbine and the electric generator, in a stable position inside said air conveyor, at the same time allowing the rotary motion of said rotating axis on itself; - a cover closing the rear part of said air conveyor; - at least two supporting elements (106, 110) placed on the outer surface of said air conveyor, in order to achieve an anchorage of the wind generator to the transportation means on which it is installed, - said wind blades (112a, 112b,...) are bent, shaped and welded to said ogive, and they have a helical convex shape with the external profile inclined towards the inside of the turbine.
