Abstract
A wind-powered device for producing electrical energy includes an electric generator set (1) which works by converting mechanical energy into the electrical energy, a wind-powered set (3) designed to capture the energy of the wind and convert it into mechanical energy, a transmission (2) positioned between the wind-powered set (3) and the generator set (1), the transmission (2) being designed to transmit mechanical energy produced by the wind-powered set (3) to the generator set (1), characterized in that the wind-powered set (3) includes at least two air turbines known as wind turbines (4) including non-coaxial shafts (5) coupled to the transmission (3), the wind turbines (4) being designed in such a way as to present an equivalent surface area to the wind that exceeds the surface area exposed to the wind of each of the wind turbines (4).
