Detailed description
The most advanced concept of housing for hydro and aero turbines, presented on figures 1, 2, 3,4, consists main leading tube 1, front widening 2, back widening 3, vertical stabilizers base 4, vertical stabilizers 5, diffusion ring 13 and conversion ring 15 between back widening 3 and diffusion ring 13. Conversion ring 15 consist at least one rotor 16 with inner and outer rings connected with blades 18. If conversion ring 15 consists of more than one rotor, like rotor 17 shown on figures with blades 19 oppositely directed to blades 18, the rotation direction of any additional rotor will be opposite to rotation direction of rotor in front of it. At the external side of both inner and outer hng of rotor 16, permanent magnets or electromagnets 28 and 29 are placed. Alternatively only on inner or outer mg of rotor 16 could be placed permanent magnets orelectromagnets either 28 or 29. In case of rotor 17 presented on figures permanent magnets or electromagnets are marked with numbers 30 and 31. Above electromagnets or permanent magnets 28, 29 electric energy inducing conductors 24,25 are placed within conversion ring. In case of rotor 17 these conductors are marked with numbers 26 and 27. Dependably of permanent magnets or electromagnets 28, 29 presence there could be either 24 or 25 inducing conductors and 26 or 27 in case of rotor 17. On pictures rotors 16 and 17 are connected with conversion ring by means of sliding bearings, but can be connected with ball bearings or any other movable connection. When fluid pass trough and around housing, by means of complex interaction with housing geometry, fluid velocity which pass trough housing is being dramatically increased, this means that more energy from the fluid inside housing could be converted into electric energy which can be done by various energy conversion systems (devices) integrated with housing. Pad of that interaction is consisted in interaction with blades (18, 19) of conversion ring which is then by means of rotors 16, 17, permanent orelectromagnets 24, 25, 26,27 and inducing conductors 28, 29, 30,31 convert into electric energy. On this way overall electric energy of device (turbine) which is integrated with housing is additionally increased.
Second option of this housing presented on figures 6, 7, 8, 9 consists all elements as previous most advanced version but without front widening 2. As such it will be easier and more compact but with different hydro or aerodynamic features.
Third cption of this housing presented on figures 11, 12,13, 14 consists all elements as second version but without back widening 3. Therefore in case of this housing variant conversion ring 15 is placed between main leading tube 1 and diffusing ring 13. As such it will be easier and more compact but with different hydro or aerodynamic features than first and second options of housings.
Effectively each of these housings variants are by its selves new concepts of devices for fluid kinetic energy conversion and fluid velocity accelerators in the same time. The electricity is being induced within inducing conductors 24, 25, 26, 27 by rotation of permanent magnets or electromagnets 28, 29, 30, 31 immovably connected with rotors 16, 17.
By combining, integrating these housings with different already known or unknown fluid kinetic energy conversion systems completely new devices (turbines) for fluids kinetic energy conversion are created.
In next lines are described integrated-combined devices with first and most advanced option of housing with other already known or unknown fluid kinetic energy conversion systems.

Electro-generating unit could be only electro-generator or electro-generator with gearbox integrated. If there is more than one rotor like presented on figures 16, 18, 19 any additional main rotor 9 with blades 11 oppositely directed to blades 10, will have oppositely directed rotation relative to rotor in front of it. Each of this additional main rotors, in this case only rotor 9, will be by additiona main shafts, shaft 23 for rotor 9, connected with additional electro-generating units, electro-generating unit 21 for rotor 9.

Dependably of number and rotors rotation direction orientation both considering rotors in conversion ring 15 and main rotors within main leading tube 1 many different conceptual combination of device (turbine) for fluid kinetic energy conversion are possible: Device (turbine) forfluid kinetic energy conversion with one main rotor 8 or 9 and one rotor 16 or 17 within conversion ring 15.

With rotor 36 are immovably connected permanent or electromagnets 38, above them and within ring electro-generator 34 are placed inducing conductors 39. By rotating rotor 8, blades 10 and rotor 36 electric energy is being generated inside electro-generating unit 20 and ring electro-generator 34. If there is more than one rotor like presented on figures 21, 23, 25 any additional main rotor, like rotor 9 with blades 11 oppositely directed to blades 10, will have oppositely directed rotation than rotor in front of it. Each of this additional main rotors, in this case only rotor 9, will be by additional main shafts, shaft 23 for rotor 9, connected with additional electro-generating units, electro-generating unit 21 for rotor 9, as well as by means of additional blades, blades 11 for rotor 9, with additional rotors, rotor 37 for main rotor 9, of additional ring electro-generators, ring electro-generator 35 for additional main rotor 9.
