This essay studies the potential difference production capacity of thermoelectric generators, generators which can convert temperature difference that is applied to the ends of the generator to electrical energy and produce a potential difference, and if they are adequate to be used in our daily lives. A thermoelectric generator (TECI-12706TI25) has been used in this experiment. The system consisted of two containers which contains water of different temperatures. Thermoelectric generator is placed between these containers and by using a digital voltmeter, potential difference between the poles of the generator is measured. Results showed that by applying the maximum temperature difference that can be applied with this apparatus (80 C°), thermoelectric generator can only produce a potential difference approximately about 0.47 volts. However, data showed that temperature difference that is applied and potential difference that is produced is not directly proportional. In fact, graph showed that the general tendency is an exponential one, meaning that by using temperature differences greater than those which are used in this experiment; much more potential difference can be produced. (167 C° should be applied to obtain 1.5 volts and to power an average LED lamp, which works with approximately 1.7 volts, 180 C° of temperature difference should be applied to the ends of the thermoelectric generator.) Results showed that thermoelectric generator can be effective in industrial places where greater temperature differences are available or near ovens. As we do not encounter temperature differences like 180 C° in our daily lives, usage of thermoelectric generators in houses will not be very effective. However, further research and development can make thermoelectric generators more effective to be used against the destructive effects of global warming as they have no harm over the environment.
