PURPOSE:To extremely reduce a system cost and enhance the efficiency of power generation, by forming a duct line with a thermoelectric transducer itself. CONSTITUTION:A pipe-formed thermoelectric transducer 21 is composed of a P-type thermoelectric transducer 23 and an n-type thermoelectric transducer 25, and both the transducers 23, 25 are longitudinally insulated by insulators 27, 29. Into the pipe-formed thermoelectric transducer 21, the non-conductive fluid of high temperature is permitted to flow, and when the non-conductive fluid of low temperature is permitted to flow outside the transducer, then conductor layers 31, 33 are formed on the internal wall and the external wall of the transducer 21. In this case, when the fluid of high or low temperature is permitted to flow inside or outside the transducer 21, then electron is shifted from the n-type transducer 25 to the p-type transducer 23, and potential difference is generated between a positive electrode 35 and a negative electrode 37, and direct current is generated.
