Abstract: A novel and useful method and apparatus for generating power from pressure changes over time within a fluid. The apparatus comprises a housing (10), and a double-sided piston (12) subject to the forces brought about by the variations in pressure of the surrounding fluid and by a restoring force such as a spring (20) or other mechanism. The resulting motion of the piston is transferred to power a generator, or is used to directly perform work. The apparatus is particularly applicable to placement in the ocean or sea where the rise and fall of the tides create the variations of pressure that drive the piston within the housing. A rising tide presents a higher pressure against the face of the piston pushing it towards the back of the housing and opposing the restoring force mechanism. A falling tide presents a lower pressure against the face of the piston allowing the restoring force to move it towards the front of the housing.
