Technology Description The SAHT (suction-augmented hydropower turbine) is a hydrokinetic turbine consisting of a multi-stage suction-producing engine for converting the kinetic energy of canal or river flow into mechanical energy. It can be described as a ducted rotary hydro-craft, comprising a concentric funnel and nozzle which enclose a torpedo-shaped hydrofoil structure at their center. A propeller attached to the torpedo-shaped internal wing drives an electrical generator. The ducts create suction forces that pull water through the rotor by creating an extreme low pressure zone behind the rotor, and this force combined with the direct pressure of canal flow onto the face of the rotor, produces an augmented volume of power.
Designed to Operate with Shore Connection? Yes
Power Transfer Method Direct drive from propeller to generator.
Mooring Configuration The turbine is attached with cables on either side of a canal or river.
Optimum Marine/Riverline Conditions Optimal conditions are canals such as the California aqueduct, where power farming is possible with the right technology. The SAHT was specifically designed for the aqueduct, where water is flowing at about 4 feet per second. Flow must be accelerated and constricted to produce useful volumes of power.
