A power plant for the generation of electricity from the flow of water currents uses turbine wheels within nozzles submerged in the water current, anchored to the bottom of the water course, as for example, the ocean, and self-buoyed to a level well below the water surface. Pairs of counter-rotating turbines are supported by their rims, which bear against friction drive wheels, which in turn drive electrical generators contained in water-tight machine rooms within the wall of the nozzle. A structural design is disclosed, providing for the building of modules of the nozzle ashore, which modules may then be barged to the deep-water site for assembly into the whole power plant.

An electrical power plant for the recovery of hydrodynamic energy from a free-flowing current of water, comprising (1) an annular nozzle for intercepting a portion of the current and permitting the remainder of the current to by-pass the nozzle, (2) the nozzle having an inner wall forming a through passageway for the intercepted portion, the passageway converging from an entrance end to a vena contracta, then diverging to a discharge end, (3) the nozzle having an outside by-pass surface extending from the entrance end to the discharge end, the inner wall and the outside surface together forming an annular chamber around the vena contracta, the inner wall having (4) an annular recess at the vena contracta extending radially outward from the inner wall into the said annular chamber, the recess having an outer wall, an upstream wall, and a downstream wall, and (5) at least one pressure-tight generator chamber constructed within the said annular chamber, and having an entrance lock in the said by-pass surface, and a generator shaft passage extending radially inward and piercing the outer wall of the said annular recess. (6) a pair of axle-less, counter-rotating, co-axial turbine wheels, (an upstream wheel and a downstream wheel) having shroud-ring rims supported within the said annular recess upon (7) bearing means carried by at least one of the downstream, outer, and upstream walls of the said recess, the bearing means supporting the turbine wheels for free rotation against radial forces, gravity, and axial fluid forces, and (8) bearing means between the wheels separating them from one another, (9) the said shroud-ring rims having inner diametric shapes for smooth flow of the water currents through the vena contracta and the wheels, and (10) the rim of the upstream wheel having a bevelled downstream face, the rim of the downstream wheel having a bevelled upstream face, (11) a bevelled friction drive roller carried on a generator shaft in the generator shaft passageway, (12) the bevels of the said rims and of the friction-drive roller being designed to cooperate for driving engagement of the roller by the two bevelled rims.
