A hydrodynamic power-generating system includes a power plant, a motion-generating subsystem, and a support subsystem for supporting the motion-generating subsystem in a dynamic water source such as a river. The motion-generating subsystem is configured to oscillate and pivot under hydrodynamic force to drive a rod. The power plant is configured to then convert the oscillating drive motion of the rod to electrical power. The motion-generating subsystem includes a pair of spaced beams having upstream ends and downstream ends. The spaced beams are pivotally supported within the water at the upstream ends thereof by the support subsystem. A pair of shafts are connected to and between the beams at the upstream ends and the downstream ends, respectively. A foil is pivotally disposed between the downstream ends of the beams. A trim flap is pivotally disposed at a downstream edge of the foil. The trim flap may be actuated between a first position which causes the foil to pivot in one direction and a second position which causes the foil to pivot in an opposite direction. The pivoting of the foil causes the beams to pivot back and forth, thereby causing the rod, which is attached to at least one of the beams, to oscillate back and forth.

[ What is claimed is:] [1.]1. A power-generating system comprising:a support subsystem;a hydrodynamic subsystem connected to the power plant and configured to generate motion under hydrodynamic force, the subsystem including:a pair of spaced beams having upstream ends and downstream ends, the spaced beams being pivotally supported within a dynamic source of water at the upstream ends thereof by the support subsystem;a rod pivotally attached to at least one of the beams;a foil pivotally disposed between the downstream ends of the beams, the foil having an upstream edge and a downstream edge; anda trim flap pivotally disposed at the downstream edge of the foil;the trim flap being actuatable between a leftward position which causes the foil to pivot rightward and a rightward position which causes the foil to pivot leftward;the foil causing the beams to pivot leftward when positioned rightward and to pivot rightward when positioned leftward, thereby causing the rod oscillate back and forth; and the hydrodynamic subsystem is disposed substantially vertically or horizontally in the source of water;a power plant connected to the rod and configured to convert the back-and-forth motion of the rod into power.
