Technology Description AMI s Ocean Swell and Wave Energy Conversion OSWEC device uses a patented linear generator to directly convert the motion of ocean swells and waves into electric power In our initial designs the generator mounts underneath a floating buoy or on the surface of a platform with the buoy below however it is possible to fit the generator on other types of wave motion energy extracting mechanisms Housing moves up and down with the motion of the Buoy on the ocean s surface while the Damping Plates hold the Generator Coil in a stable position The relative motion between the magnetic field in the generator housing and Generator Coil creates an electric voltage in the Generator Coil After four design evolutions Aqua Magnetics Inc has created our patented reciprocating linear generator Scalable for a wide range of applications and able to operate in a wide range of sea states Generator prototype will produce approximately 10 watts of power in 15 cm 6 inch wind chop in the intraco

Mooring Configuration The mooring system use will be a 3 point slack line system The achor type will depend on the bottom configuration
Optimum Marine/Riverline Conditions AMI calculates the power capacity for the 1 meter diameter buoy operating in 2 meter ocean swells with an approximate period of 7 5 seconds The calculations for the 10 meter diameter buoy are for a 3 25 meter swell with an approximate period of 10 seconds
