The turbine is intended especially for the conversion of wind energy and comprises a rotor shaft arranged on a mast and at least one flow capturing blade. The at least one flow capturing blade (1) is formed from a strip-shaped, inherently flexible band (3). The loop (2) is arranged concentrically or eccentrically on the rotor shaft (4) and the two chords (5) are fixed by their longitudinal centre lines (6) to their holders (7) with a variable angular position in relation to the rotor shaft axis (4). <IMAGE>
