• FIG. 1 The illustration of a flow energy plant S integrated into a car 24 is indicated in FIG.
• the flow turbine S designed as a wind turbine with a horizontal rotor axis A1 is integrated in the radiator grille 24 of the vehicle. By a slim design of the wind turbine W, this is optimally integrated in it.
• On one or both sides of the rotor 1 are e.g. Generators (not shown) connectable.
• the energy generated by the fluid power plant S is converted into other forms of energy, as needed, using suitable transmissions (e.g., gear transmissions, toothed belt transmissions), clutches, e.g. to compensate for relative movements between a drive shaft (here shaft of the rotor) and an output shaft (e.g., shaft of a generator) and corresponding transducers converted.

• the flow energy system can be swiveled as required and can work with horizontally or vertically aligned rotor axes. It is also possible to pivot the flow energy plant (symbolically within an imaginary spherical body) in any position.
• the solution according to the invention can thus be used for a wide range of applications.
• the energy yield can be increased by more than 5-fold compared to conventional flow energy systems.
• Conventional, in particular three-bladed horizontal wind turbines can produce unacceptable acoustic and visual effects.
• the noise level is often over 35 dB, which is especially annoying at night.
• the change between light and shadow, and especially in sunshine the "disco effect" when light is reflected irregularly from the bare surfaces of the rotor blades, in the long run unbearable.
• the large outer surfaces 9a, 10a of the diffuser elements 9, 10 can be used as an advertising medium.
