I claim: 1. A power unit placed in a fluid stream, comprising: a common stationary hollow axle; a first orthogonal turbine and a second orthogonal turbine, coaxially mounted in relation to each other; each said turbine including an outer supporting ring, an inner supporting ring, a first plurality
I claim: 1. A power unit placed in a fluid stream, comprising: a common stationary hollow axle; a first orthogonal turbine and a second orthogonal turbine, coaxially mounted in relation to each other; each said turbine including an outer supporting ring, an inner supporting ring, a first plurality of blades mounted on the inner and outer rings of the first turbine, a second plurality of blades mounted on the inner and outer rings of the second turbine, and a hollow shaft rotatable substantially around said axle; wherein the shafts are aligned substantially transversely to the stream, and essentially support the respective supporting rings; the blades having a hydro-dynamical profile with a capability of angular adjustment; said first plurality of blades and said second plurality of blades are oriented symmetrically in the opposite directions in relation to each other causing rotation of the turbines in the mutually opposite unchangeable directions irrespective to the stream's direction; and an electro-generator, disposed between the turbines, including two short-circuited annular rotors including the inner rings of the turbines; said inner rings are made of material capable of conducting a predetermined magnetic flux, said rotors including flat rings, inwardly attached to the corresponding inner rings, said flat rings are made of material capable to conduct a predetermined electric current; at least one bilateral inductor including a magnetically conductive core, an arm made immovable along the circumferential direction and fixedly attached to said core, a frame fixedly mounted substantially on said axle and half-hingedly attached to said arm, so that the arm with the core are capable of axial displacement relatively to the rotors; a three-phase winding composed of three phase coils, wherein a first coil and a third coil are cross-wisely wound up on said core relatively to each other, and a second coil is transversely wound up on said core between the first and the third coils, thereby forming two magnetic fluxes running in the opposite directions on the opposite sides of said inductor facing the opposite rotors; and anti-frictional pads installed in the gap between the rotor and the corresponding side of said inductor, wherein the pads are supported by said arm. 2. The unit according to claim 1, wherein said blades are aligned perpendicularly in relation to the respective supporting rings, which they are mounted on. 3. The unit according to claim 1, wherein said blades are aligned with a tilt in relation to the respective supporting rings, between which they are mounted on.
