ABSTRACT:
A water-going vessel propelled via a plurality of parallel sets of two underwater turbines disposed along the underside of said vessel, with each turbine mounted on respective retractable struts. A plurality of sets of turbines extend from respective turrets disposed along the longitudinal midline of the underside of the vessel, each of said turrets rotatable through 360 degrees and each having extending therefrom one turbine set. Hull construction pieces of the vessel preferably comprise an outer and an inner containment wall within which a plurality of touching hollow spheres are sandwiched and wherein a plurality of individual lengths of high strength sheaths are within respective tubes which are parallel with the containment walls and disposed within intrices formed by the spheres. The individual lengths of sheaths are connectable to each other to form a network of sheaths encircling the hull. Stress can be introduced and adjusted within each length of sheath which is a part of the network. Also disclosed is an improved underwater turbine, wherein the improvement comprises a plurality of housings surrounding respective portions of the turbine, with each of said housings having therein rotatable blades and, immediately rearward of said blades, a plurality of nozzle openings through which a gas under pressure can exit in a path of flow directed along the outer wall of said turbine.
