Abstract

A tidal or wave energy harnessing device (10) comprises a float (12); and a pump arranged to be driven by tidal or wave motion of a body of water. The pump comprises a piston chamber (14), connected to the float (12) and having a first inlet (16), a second inlet (18), a first outlet (20) and a second outlet (22). The pump further comprises a piston (28) comprising a piston head (30) which is movably received within the piston (chamber 14) and which has first and second pressure faces (30a, 30b), the piston (28) being configured to be anchored to a floor supporting said body of water. The piston head (30) is movable relative to the piston chamber (14) as a result of movement of the piston chamber (14) resulting from the tidal or wave motion of said body of water. The first inlet (16) and the first outlet (20) are in fluid communication with the first pressure face (30a) of the piston head (30), and the second inlet (18) and second outlet (22) are in fluid communication with the second pressure face (30b) of the piston head (30). In use, the piston chamber (14) is substantially submerged in the body of water.
