Abstract
The present invention is an underwater power generation system engineered for operation in a low-flow environment on a seafloor or riverbed. Features of the system include a hybrid Savonius C foil and Darrieus helical foil hydro-kinetic (HK) turbine for primary power generation and a microbial fuel cell (MFC) for secondary power generation. Both power generation sources are secured to a base frame and may be used to charge a rechargeable battery. Anodes from the MFC preferably rest in anoxic sediment on the seafloor or riverbed. The rechargeable battery may be used to power target electrical equipment that may include sensors, data-logging, communications and other electronic functionality operating underwater.
