An oscillating fluid flow motor and a fluid flow power system that converts the energy in the flowing fluid to mechanical energy through a vane that automatically sweeps back and forth across the flow. In one embodiment of the oscillating fluid flow motor, the motor includes (1) a support structure, (2) an elongated swing arm pivotably and rotatably mounted to the support structure, (3) a vane having a concave face, (4) an elastic link operatively coupled in tension between the swing arm and a support, and (5) a direction control mechanism operatively coupled to the swing arm. The vane is connected to the swing arm so that, upon rotation of the swing arm about its longitudinal axis, the orientation of the concave face of the vane changes relative to the flow of a fluid confronting the face. The direction control mechanism is operative to selectively re-orient the face of the vane at each of two points that define the ends of the bidirectional stroke of the swing arm.
