Abstract: A system for conversion of ocean waves into usable mechanical energy includes at least one weight configured for movement along a linear path having a determined length where an orientation of an angle of the linear path with respect to gravitational forces is varied by forces of the ocean waves in a manner to cause the at least one weight to travel along the linear path due to the gravitational forces. At least one linkage translates the travel into the usable mechanical energy. The travel is in two directions and the at least one linkage translates the travel in the two directions into the usable mechanical energy. The at least one weight may include a water tank filled with water for operation of the system and may be emptied for transportation of the system. The usable mechanical energy can be used to operate an electric generator to produce electricity.
