An improved power unit placed in a fluid stream, comprises a common stationary hollow axle, two coaxially mounted orthogonal turbines, having hollow shafts oppositely rotatable around the axle, inner and outer rings, adjustable blades attached to the rings, an electro-generator located between the turbines including two annular rotors formed on the inner rings with flat electro-conductive rings attached thereto, circumferentially immovable bilateral inductors having a core fixed to an arm half-hingedly coupled with a frame mounted to the axle enabling axial displacement of core relatively to the rotor, a winding having a first and third coils cross-wisely wound up on the core, and a second coil transversely wound up between the first and the third coils, forming two magnetic fluxes running in the opposite directions on the opposite sides of inductor facing the rotors, and electric cables for power takeoff mounted on the frame and passed through the axle.
