A 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. The converter consists of a pair of contra-rotating conveyor-type turbines, connected to electrical generators, and a water flow accelerator. Each turbine comprises a conveyor mechanism, which is mounted via bearings on inner vertically-oriented shafts to a protecting housing, and a plurality of rectangular-shaped blades (preferably three), which are held by blade support members in the position maximizing the turbine's performance. The system module is capable of self-adjusting to the optimal position in water currents, vertically with changing water levels and horizontally, depending on the direction of a water flow. It uses a simple anchoring mechanism and can be easily relocated. An array of these modules can be connected to an underwater transmission line to create a robust and cost-effective power generation system. |
