Abstract

A number of different sized floats are connected into an array through nonlinear interfaces so their relative motions drive hydraulic pumps. Floats in the array are sized to present a 'black body' to the ocean waves incident upon the array. fluid moved by the pumps is used to drive an electric turbogenerator. The sizes of the floats are chosen to allow the floats to dynamically couple into a number of wavelengths of the wave motion.
