Characteristics of a rocking wave power device

Abstract

THE possibility of extracting a large proportion (more than 80%) of the total wave power from water waves has been demonstrated experimentally1 using a specially contoured rocking device. In considering the possibility of large scale power generation, it is necessary to understand how such a device would respond to the variable Atlantic ocean conditions where wave periods are between 7 s and 14 s for 99% of the time2. We here present the results of initial investigations of the bandwidth of wave periods covered by Salter's1 device.
