1. A wave energy conversion system comprising:
at least one linear module comprising:
an actuated subassembly having an actuated shell and a passive translator supported by the actuated shell;
a reference subassembly having a reference shell concentrically received in the actuated shell and an active stator, said actuated subassembly and the reference subassembly configured to telescopically reciprocate longitudinally, the passive translator and active stator coupled as a linear electric direct drive machine;
a connection from the reference shell to a reference body on a sea floor; and
a buoyant wave activated floating body connected to the actuated shell, the floating body comprising a buoy;
wherein the actuated shell and reference shell cooperatively form a chamber having varying volume responsive to longitudinal expansion or contraction of the actuated subassembly and the reference subassembly, and the buoy incorporates a flexible pressurization bladder in fluid communication with the chamber configured to mitigate pressure differential due to volumetric changes of the chamber.
