Patent ID: 6998730

Claim:
An underwater hydro-electric generator assembly for use in a hydro-electric farm comprising: an electrical generator portion coupled to a turbine/blade propeller portion, wherein surfaces of components exposed to the water for each portion are coated with a non-conductive, heat dissipating, anti-fouling and water specific protective coating, and wherein the electric generator portion includes a brush-less rotator assembly, the brush-less rotator assembly comprising: a transmitting ring around a turbine blade/propeller shaft, the transmitting ring having circumferentially spaced-apart transmit nodes; a reception ring having circumferentially spaced-apart reception nodes, said reception nodes being connected to reception tabs which are embedded into windings of electromagnets of a rotator electromagnet assembly of the electric generator portion; and a protective spacer ring circumferentially located between the transmitting ring and the reception ring, the protective spacer ring having circumferentially spaced-apart apertures aligned with the transmit nodes and the reception nodes, wherein electrical charges required for the electromagnets to maintain their polarity is fired between the transmitting nodes and the reception nodes through the protective spacer ring apertures letting the water provide the electrical connection between, and wherein the water can flow through the electric generator portion between the rotator electromagnet assembly and a stator field winding assembly and through spaces in each of said rotator electromagnet assembly and said stator field winding assembly.
