A stream energy extraction device (1) including endless ropes (2) running around sheaves (4, 41, 4"), there being connected, along at least one rope (2), submerged sail- or vane-like elements (6), flowing water causing the sail- or vane-like elements (6) to be moved in the water, whereby at least a portion of the stream energy of the water is transmitted to the rope (2), the rope running, where at least a component of the moving direction of the rope (2) is upstream, in a channel (16). |
