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.

1. Wind turbine for converting wind into mechanical energy, comprising: a support,a vane rotatively connected to said support, the vane comprising multiple receptacles positioned along a length of the vane, each receptacle adapted to adopt a first configuration when the vane is in a position to travel in a 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, and one of said multiple receptacles positioned near the support has a larger cross-section than one of said multiple receptacles positioned further away from the support, andan arrangement that is operable to force each receptacle to adopt at least one of the said configurations independent from the direction of the wind,wherein the multiple receptacles are operatively connected such that when a receptacle of the multiple receptacles adopts the second position, a receptacle of the multiple receptacles next to the receptacle that adopts the second position, viewed in a direction away from the support, automatically adopts the second position. 2. Wind turbine according to claim 1, each receptacle adopts one of the said two configurations under the influence of gravity and the wind, and the other configuration by operation of said arrangement. 3. Wind turbine according to claim 1, wherein the arrangement is operable such that each receptacle adopts the second configuration by operation of said arrangement when the vane is in a position to travel against the direction of the wind. 4. Wind turbine according to claim 1, wherein the vane includes an aerofoil shaped body, and each receptacle is formed by a lid and the aerofoil body, the lid being hinged to the body at a position adjacent a downstream end of the said body. 5. Wind turbine according to claim 1, wherein the vane comprises a first of said multiple receptacles at a top side of the vane and a second of said multiple receptacles at a bottom side of the vane. 6. Wind turbine according to claim 1, wherein the vane is part of a rotor that is rotatably connected to the support, and the rotor comprises multiple vanes. 7. Wind turbine according to claim 6, wherein the turbine comprises multiple rotors. 8. Use of a wind turbine according to claim 1, wherein the turbine converts wind into work. 9. A wind turbine according to claim 1, wherein the wind turbine is used with a Darrieus wind mill and the wind turbine is operatively connected to the Darrieus wind mill by an operative connection which comprises a clutch that allows that the wind turbine to rotate at various revolutions per minute for a predetermined number of revolutions per minute for the Darrieus wind mill. 10. A wind turbine according to claim 9, wherein the clutch is selected from the group consisting of a centrifugal clutch, an hydraulic clutch, a slipper clutch, an electromagnetic clutch and a vee-belt clutch. 11. A wind turbine according to claim 1, wherein the said first and second configurations are induced only by at least one of the following:wind,gravitational forces andsaid arrangement,wherein the vane comprises said multiple receptacles as multiple separate receptacles positioned along the length of the vane,wherein one of said multiple receptacles positioned near the support has a larger maximum capacity to convert wind force into motion than one of said multiple receptacles positioned further away from the support. 12. A vane provided with at least one of multiple receptacles as defined in claim 1, and further comprising an arrangement as defined in claim 1 for use in adopting the first and second configuration. 13. A vane according to claim 12, wherein the vane comprises two of said multiple receptacles positioned at corresponding sides above and below the vane, the two receptacles being formed by lids that can open and close with respect to the vane, each of the lids of the said two receptacles is rotatably positioned in the vane by connection to a pinion, and the two pinions cooperate via a grasping connection.
