Electric power generator system using ring-shaped generators and essentially being formed of turbines and generators, and optionally converging-diverging nozzles. The turbines may optionally have an open center, and may be of any type, such as axial turbines, reel-shaped turbines, cycloidal turbines optionally with an annulus, helix shaped turbines, etc. In addition, the blades of the turbines may or not be curved and/or articulated. The generators can be of permanent magnets or variable reluctance, non-watertight and optionally independent. The exciter can be made of a ring (of magnets, or of areas having alternately high and low magnetic permeability) around the blades, and the armature (magnets with windings, or coils with a high-permeability core, depending on the case) forming an arc or ring fitted in the housing or the nozzle and/or the stationary inner cylinder or ring (or braced ring system) in the case of open-center turbines.
