Abstract: The invention relates to a driving force generating device including a column (1) provided with a plurality of flexible elements (3) positioned around the column (1), which react in response to the flow by rotating positively in the same direction. The invention is characterised in that the flexible elements take the form of aerodynamic membranes (3), the arrangement and shape of which correlate with logarithmic spiral patterns. The invention is also characterised in that it includes a movable head (2) positioned in the upper part of the central column (1) and a base (4) positioned in the lower part of said column (1), the upper part of each membrane (3) being secured to the movable head (1) and the lower part of each membrane being secured to the base (4). The invention can be used to balance kinetic, gravitational and centrifugal forces, thereby minimising resistance.
