Abstract: A flow energy installation with a roller-like rotor (1) is presented. The roller-like rotor (1) rotates about an axis (A1) and has a plurality of rotor blades (2). One of the rotor blades (2), a plurality of the rotor blades (2) or all rotor blades (2) have associated with themselves at least one efficiency-improving fluid conducting fin (3) which in the direction of rotation is arranged upstream or downstream of the rotor blade (2). The rotor (1) is at least partly surrounded by at least one efficiency-improving diffuser element. The flow energy installation can be operated with liquid and/or gaseous media at any desired orientation of the axis (A1).

Abstract: Continuous-flow energy installation having at least one rotor (1), which rotates around an axis (A1), having rotor blades (2), an inlet surface structure being associated with the rotor, and the rotor blades and/or the inlet surface structure at least partially consisting of one or more air cushions.

Abstract: Flow energy installation with at least one in particular roller-like rotor (1) which rotates about an axis (A1) and has a plurality of rotor blades (2), wherein one, a plurality or all rotor blades (2) have associated with them at least one efficiency-improving air conducting fin (3) which in the direction of rotation is arranged upstream or downstream of the rotor blade (2) and/or the rotor is at least partly surrounded by at least one efficiency-improving diffuser element, and wherein the flow energy installation can be operated with liquid and/or gaseous media at any desired orientation of the axis (A1).
