Abstract

A hydro-kinetic power generation system is disclosed. The system includes a structure to be positioned in shallow or deep waterways, such as canals and rivers. The structure may be modular, such that the structure may be composed of one or more structural units that are each substantially the same. In various embodiments, each unit includes one or more curved walls for accelerating water through the unit, or through the structure as a whole. In one embodiment, the accelerator walls are curved for optimizing water flow through the structure without generating undue head loss. In certain embodiments, the units may be configured such that the accelerator walls are positioned on opposite sides of the structure, or the accelerator walls may be adjacently positioned. Coupled to the structure are turbines and gear box systems for harnessing energy from the moving water and converting the energy into electric power.
