Abstract
A tidal power generation system has a vertical post being embedded in a sea floor and a floating barge operably coupled to the post. The floating barge has a gear rotationally driven by the post as the floating barge moves vertically with respect to the vertical post. An offshore hydraulic pump is operably connected to the gear, an onshore hydraulic motor operably connected to the offshore hydraulic pump by a hydraulic circuit; and an electric generator is operably connected to the onshore hydraulic motor.

A tidal power generation system comprising:
- a vertical post embedded in a sea floor;
- a floating barge operably coupled to the post, the floating barge having a gear rotationally driven by the post as the floating barge moves vertically with respect to the vertical post;
- an offshore hydraulic pump operably connected to the gear;
- an onshore hydraulic motor operably connected to the offshore hydraulic pump by a hydraulic circuit;
- and
- an electric generator operably connected to the onshore hydraulic motor, wherein the system further comprises an onshore hydraulic fluid reservoir and an offshore hydraulic reservoir operably coupled at respective ends of the hydraulic circuit,
- wherein the hydraulic circuit comprises a single hydraulic channel so that hydraulic fluid flows from the pump to the motor via the channel and then back from the motor to the pump via the channel.
