SAE Nereus I

The Nereus I is a bottom mounted tidal energy converter developed by SAE. The device builds upon the design of the SAE Aquanator, but with increased scale to 150 kW. The Nereus I device consists of dual ducted axial rotors mounted on either end of a common structure and uses Aquafoils to capture momentum from the flow of water to drive a chain perpendicular to the flow. In turn, the chain drives a generator to convert the mechanical energy into electricity. This turbine system is suited for shallow water locations in rivers, man-made structures, or open ocean tidal streams.
