ABSTRACT:
A waterbound facility, serving the extraction of energy from the water current in which it is moored, consists of a seaworthy vessel, which carries cycloidal turbines, extending their impeller blade assemblies through the vessels bottom into the current. Deployable shrouding, guide vanes and underwater sails serve the concentration of flow. Retractability of turbines and ballast tanks provide draft control for entering harbors.
