NOVELTY - The method involves inserting disk rotor generators and motors or pole generators (6) in communication with regulation elements in a closed circuit or alternative open disk rotor turbines (4a,4b) for providing current-controlled operation and heat-controlled operation or combined operation. The energy demand is controlled, optimized and adapted at different end-user, where different mediums, such as water, organic rankine cycle and carbon dioxide are utilized.    USE - Method for recovering electrical energy and compressed air from exhaust gases, waste heat or residual heat and heat produces in stationary plants such as power plants, industrial furnaces, steel mills, glass melting, cement factories, paint shops, cogeneration plants, mini cogeneration plants in house technology, in waste recycling, solar systems, in stationary air conditioning, geothermal systems and in mobile systems, particularly in transport system, such as in cars, trucks, trains, ships airplanes and special machines, by electrical energy and compressed air recovering device (Claimed).    ADVANTAGE - The method involves inserting disk rotor generators and motors or pole generators in communication with regulation elements in a closed circuit or alternative open disk rotor turbines for providing current-controlled operation and heat-controlled operation or combined operation, and hence enhances energy efficiency, and recovers electrical energy and compressed air in economical manner, where the friction losses are also reduced.
