ABSTRACT
The possibility of generating electrical power from these deep water waves has been realized for many years, and there are countless ideas for machines to extract the power. In recent years interest has revived, particularly in Japan, Britain and Scandinavia, so research and small scale development has progressed to the stage of commercial construction for meaningful power extraction. As with all renewable energy supplies the scale of operation has to be determined, and present trends support moderate power generation levels at about 1MW from modular devices about 50 m wide across the wavefront. Such devices should be economic to replace diesel generated electricity, especially on islands.
