NOVELTY - An electro-generator has a frame pipe (1) with widened ends (2), two rotors (6) each equipped with blades (8,9), induction chambers (15), induction conductors (16), sources of magnetic radiation (17) with ball bearings (18), and conductors for conveying electrical energy (19) specified by the sources of magnetic radiation located at the blade ends and tightly connected to the blades. The blades of one rotor are oriented contrary oriented to the blades of the other rotor.    USE - Electro-generator acting as pipe turbine and driving propeller. Uses include but are not limited to converting kinetic energy of water flowing through rivers or through water pipes with pressure regulation or plumbing systems with natural difference in pressure found in household or industries, controlling quality of water in rivers as well as people and goods and other biological, ecological and social factors which are in direct connection with rivers, efficient usage of energy of massive water current in sea and ocean currents when applied on movable underwater platforms, and serving as a efficient, compact driving device for electric driven vehicles used on land, water, and or air.    ADVANTAGE - Kinetic flow energy through regular or standard pipes or hoses which would otherwise be wasted may be momentarily used, processed, or partially stored in e.g. batteries, electric accumulators, for later use. Certain savings in electric energy consumption are being achieved which could be noticeable especially in living units with large number of inhabitants or in industry where large traffic of fluids exist. Implementation of electro-generator in rivers make possible harvesting river flow kinetic energy without building hydropower plants, creation of hydro accumulating lakes, or causing significant disturbance of river and coastal ecosystems and flooding and destroying coastal areas. Implementation of electro-generator in sea and oceanic currents, especially if they are implemented on underwater mobile platforms make possible the most efficient harvesting of massive water streaming kinetic energy regardless of their movement inconsistency in direction, aim or depth. The fact that the electro-generator functions as a pipe turbine and or a propeller provides great benefits in mobility and flexibility of use. Because the source of rotational force is at the end of propeller blades of inside rotor, and affects around the. inside rotor-propeller itself, more efficient relation between electric energy consumption and propulsion power is being achieved.
