Abstract: An ocean wave energy system is for generating power from ocean waves. The system comprises wall components defining one or more channels for guiding propagation of ocean waves therealong. Each channel has a first end for receiving the ocean waves and a second end remote from the first end. A float arrangement is disposed along each of the one or more channels between its first and second ends. Moreover, the float arrangement being arranged in size to progressively absorb energy from the ocean waves commencing with longest wavelength components in the waves and finishing with shortest wavelength components in the waves. The ocean wave energy system is capable of extracting energy efficiently and conveniently from ocean wave motion.
