Abstract

A generating apparatus for generating electrical power from a water flow to electrical energy includes a support structure; an electrical power generation arrangement; and a drain tank. The support structure includes a pipe extending into seawater, a tidal stream generation device in the pipe, and a water tank in fluid communication with the pipe. The tidal stream generation device includes a turbine for directing seawater from the pipe therein, a shaft co-rotated with the turbine, a reduction gearbox connected to the shaft, an output shaft extending out of the reduction gearbox, an alternator driven by the output shaft to convert mechanical energy to electrical energy, and an electrical grid electrically connected to the alternator. The electrical power generation arrangement includes at least one electrical energy generation device in communication with the water tank. Each electrical energy generation device includes interconnected bends and tidal stream generators in the bends.
