Lancaster University PS Frog
PS Frog Mk 5 is essentially a large buoyant paddle with a reaction mass and internal apparatus that allows power to be extracted (Fig. 1). In the example presented in this paper, the internal power take-off. (PTO) means are taken to be in the form of a sliding mass, which converts the wave disturbance into differential mechanical motion within the device. The mechanical motion is then used to drive an electrical generator, via a hydraulic transmission.
