NOVELTY - This invention deals with an improved device that converts the physiologically derived energy into an efficient electric energy. The auto-pneumatic electric generator is an advanced, automatic, useful, efficient & non-air-polluted device, which generates a plenty of desired electric energy by utilizing free air. The device comprises the auto pneumatic valve and pneumatic electric generator to generate electric power. The pneumatic electric generator comprises two light weight driving wheels, two set covers and a stator with freely movable rotor inside. The stator also forms the middle body of the generator, each driving wheel consists number of curved blades on its outer rim, which opposes to compressed air and drives the driving wheel. The driving wheel is placed on each end of the rotor shaft that comes out from both side of the stator. The two round side covers called housing covers each driving wheel and fitted on both side of the stator and forms a closed passageway for compressed air. Each housing comprises inlet port for compressed air and outlet for exhaust housing and stator combinedly forms the closed compact body of the generator. The auto pneumatic valve used in the device comprises of inlet port and outlet port, variable setting set screw, rubber cork and a lever connected to the bush with hole present inside the valve. The valve is used to store the compressed air as-it-is in the air storage tank and to restart the device in case of normal or unwanted or emergency shutdown by simply pushing down the lever down, and act as a automatic on/off switch, and saves the time and energy. A foot-operated air pump is used to manually compress & fill the compressed air in the air storage tank and this compressed air is impacted on the driving wheel through inlet ports and released through outlet ports of the generator, as the driving wheels rotate the rotor also rotate and produce electric energy. This derived electric energy is then passed to constant voltage stabilizer system to provide constant voltage supply to output terminals. The electric motor driving the air compressor internally connected to output terminals, start working and re-fill free air into the air storage tank and completes the cycle and makes the device automatic.
