ABSTRACT: “If you and I were to exchange dollar bills Neither would be richer But if we were to exchange ideas Each would increase knowledge This paper outlines the production of electrical energy (d.c) from automobile radiators heat using thermocouples. When any conductor is subjected to a thermal gradient, it will generate a voltage (thermoelectric effect or Seebeck effect). A thermocouple can produce current, directly without the need for extra circuitry and power sources. The fluid circulates through exposed pipes of radiators in automobiles tend to transfer heat mainly by convection and might logically be called convectors. The upper hose of radiator serves as the measuring junction (hot) and similarly the lower hose of radiator serves as the reference junction (cold)for the thermocouple .The measuring junction of thermocouple is coupled with the engine outlet hot water (upper hose) and reference junction is coupled with the inlet water to engine (lower hose). Due this temperature variation, electrons start flows from the hot junction to the cold junction. Hence the electricity is produced and it can be stored and used for various utilities. The produced power is directly proportional to the temperature difference in the junctions of thermocouple.

Thermocouples are a widely used as temperature sensor for measuring temperature and can also be used to convert a heat gradient into electricity. They are inexpensive, interchangeable, are supplied with standard connectors, and can

measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. Any junction of dissimilar metals wills produce an electric potential related to temperature. Thermocouples for practical measurement of temperature are junctions of specific alloys which have a predictable and repeatable relationship between temperature and voltage. Different alloys are used for different temperature ranges. Properties such as resistance to corrosion may also be important when choosing a type of thermocouple. Where the measurement point is far from the measuring instrument, the intermediate connection can be made by extension wires which are less costly than the materials used to make the sensor. Thermocouples are
