NOVELTY - The turbine has a rotor assembly comprising a light weight runner (3). A set of blades is coupled to an end of the runner and a magnet (8) is enclosed within another end of the runner. A fixed stator assembly is embedded between an inner surface and an outer surface of a flow enhancer housing (1). A fixed stator (10) comprises an electrical circuit, and is aligned with the magnet. A power collector (12) enables flow of electrical current from the stator assembly to an external current sink, where the collector is coupled to the stator.    USE - Water submerged turbine for conversion of energy below surface currents into electrical current.    ADVANTAGE - The turbine has light weight shaft, thus reducing overall weight and bulkiness of the turbine. The turbine eliminates the need for in-line speed increaser, mechanical coupling between the runner and the electrical generator and an in-line electrical generator. The turbine has fully submersed and completely water tight sealed housing, thus isolating the entire stator from water, while preserving electromagnetic coupling efficiency with rotor permanent rotating magnetic field. The turbine enhances the flow across the housing and increases the pressure drop between the inlet and the outlet. The turbine eliminates the need for secondary control on the runner blades, stay vanes, mast, tripod or pillar. The turbine allows producing electrical energy at variable frequencies, thus maximizing the overall efficiency. The turbine prevents generation of green house gases and allows simultaneous groups operation with or without existing grids. The turbine allows extracting renewable energies at affordable price per kilo watt hour and reduces the manufacturing cost per kilo watt hour. The turbine enhances reliability, reduces maintenance cost, is transportable and can be relocated without requiring demolishing or large civil engineering processes. The turbine avoids the need of expensive tripods, mast, or pillars to be located or lifted to surface.
