resistance vanes 24 are constructed of suitable material that is light in weight but is strong enough to deter detrimental deformation when there is no wind all the vanes 22 hang to a vertical position the entire system is supported by vertical support 28 which contains axial and radial bearing support and positions the entire rotating mechanism to a desired elevation in fig4 another vane support structure is shown using spokes 16 as an alternative a thin flat circular disc could be used as a support structure for the hinged vanes 22 this invention applies to all support structures that allow the attachment and function of the hinged vanes 22 in fig5 another configuration of the vanes 22 is shown this configuration conserves vertical space vanes 22 may take on a variety of shapes vanes 22 are shown as being flat but may take on a variety of other shapes that enhance forces of gravity and transmission of wind forces in fig6 two vane support structures are shown stacked to capture and transfer more wind energy to hub 18 the vane support structures may rotate in opposite directions and be connected to concentric drivers although two vane support structures are shown more than two are possible fig7 and fig8 show a possible hinge configuration hinge 20 is shown attached to spoke 16 and vane 22 using rivets 32 other means of attachment may be used any hinge device that allows planar rotation of vane 22 may be used vanes hang from a rotatable support system when there is no wind however when the wind blows vanes on one side side 1 of.
