O UR F OCUS � simple is better � offshore where the energy is greatest with the lowest impact � low cut-in/no cut-out � on-station maintenance � no specialized equipment � end of life recovery only 8

S TING RAY wave direction floating, offshore, mega-watt scale device composite structure � � very few moving parts umbilical connection � 2 direct-drive permanent magnet generators reduced-impact mooring devices to be arrayed in arrays � 3rd generation design � over 15 years of academic and corporate R&D � 9
