Abstract:
1. An apparatus for using flow energy, especially wind energy, with elongated elements which travel around a closed path and comprise incident-flow surfaces which face the flow, wherein the elongated elements are arranged parallel to each other and a certain distance apart to form a rotating cage or an endless traveling belt, which travels along a guide and on which the elongated elements form rungs, the axis of rotation of the elongated elements or the deflection axes of the elongated elements being transverse to a direction of the flow, wherein, during travel of the rotating cage or the endless traveling belt, the elongated elements can be pivoted independently of each other such that incident-flow surfaces are in a proper orientation to the flow and wherein, during travel of the rotating cage or the endless traveling belt, the orientation of each elongated element can be controlled individually, the apparatus further comprising a control unit for the automatic orientation of the elongated elements to adapt them to the flow direction and/or to flow intensity and/or to rotational speed of the rotating cage.
