Abstract: The invention pertains to a dual-turbine wind power station arranged on a vertical axis, having a machine housing (1) constructed over a solid base, a roof-like structure (2) appropriate to its height, and an internal rotor (3) composed of a series of blades. The wind power station is characterised in that the external rotor (10), which rotates in a direction opposite that of the internal rotor (3) and that is also composed of a series of blades, is arranged on a vertical axis it shares with the internal rotor (3). The lower shaft ends (4, 11) of the internal rotor (3) and external rotor (10) are furnished with lower sets of bearings (5, 12), while the upper shaft ends (6, 13) are furnished with upper sets of bearings (7, 14), all sets of bearings providing for rotation motion about the vertical axis.
