Abstract: A power generating system operates in a flowing body of fluid, such as water or air. The system includes a continuous loop member engaging and rotating around two rotatable members, which, in turn, are operatively connected to a generator. The continuous loop member can include a plurality of attachment arms that extend outwardly therefrom. A collapsible fluid catchment device can be attached to each attachment arm. The fluid catchment devices can open in the direction of movement of the water thereby driving the continuous loop member and, consequently, the rotatable members. When moving against the fluid flow, the catchment devices can collapse to a closed position to thereby reduce drag. The attachment arms are long enough so that the catchment devices are spaced a sufficient distance from the continuous loop member to prevent contact with the rotatable members and the continuous loop member when the catchment devices are fully open.
