A brief history of attempts to use ocean surface wave energy is presented and applicable wave theory is reviewed. Six distinct modes of interaction between a wave and a buoy are defined. These are evaluated by deriving expressions for the maximum power realizable from each and by considering how the use of each would affect buoy functioning. Those modes involving the buoys reaction to the rise and fall of the ocean surface and the use of the fluctuating pressure field beneath a wave train are selected for further study. A buoy motion analysis supplemented by limited experimentation into linear damping coefficients is presented in connection with the first of these. Conceptual-level conversion system designs are proposed and compared with other power systems adaptable to buoy use in terms of their energy densities and specific costs and by subjective consideration of their adaptability to long-term unattended use in the ocean.
