Technology Description The Aquabuoy 2.0 is a large buoy tied to a shaft. By bobbing up and down, the water is rushed into an acceleration tube, which in turn causes a piston to move. This moving of the piston causes a steel reinforced rubber hose to stretch, making it act as a pump. The water is then pumped into a turbine which in turn powers a generator. The electricity generated is brought to shore via a standard submarine cable.
