A mobile modular system for producing electricity from water currents is disclosed. Each module contains a submersible water current energy converter and a self- adjusting buoyant mooring mechanism. A converter consists of a pair of contra-rotating vertical axis wing-type turbines, connected to electrical generators, and a water flo w accelerator. Each turbine comprises a hub, which is mounted via bearings to the protectin g housing, a plurality of radial wings, and an arrangement of paddles with mutually perpendicularly oriented floatable and sinkable blades. The hub and wings are filled with a buoyant material to eliminate the vertical load applied to axis bearings. The system module is capable of self-adjusting to the optimal position in a river current vertically and horizontally. It uses a simple anchoring means and can be easily relocated. An array of modules may be connected to an underwater transmission line to create a robu st and cost- effective power generation system.
