Abstract: A wind turbine for converting wind into mechanical energy, includes a support and a vane rotatably connected to the support, the vane including a wind receptacle that can adopt a first configuration when the vane is in a position to travel in the direction of the wind, in which first configuration the receptacle has a first capacity to convert wind force into motion of the vane, and a second configuration when the vane is in a position to travel against the direction of the wind, in which second configuration the receptacle has a second capacity to convert wind force into motion of the vane, the second capacity being lower than the first capacity, wherein the turbine is provided with an arrangement that is operable to force the receptacle to adopt at least one of the configurations independent from the direction of the wind.
