Abstract: This paper presents an experimental investigation of nano power generation, less than 1 kW size, using Thermoelectric Generator (TEG). The heat source is harvested from the waste temperature of the incinerator, but in the laboratory experiment, it was generated from an electric heater and controlled by an electronic thermostat. A prototype of 0.02 kW system, consisting of 24 modules of bismuth telluride TEG connected in series, was built. The system is attached to cooling and temperature controller to investigate the characteristics. Preliminary experiments and analytical models of electric output power as function of specific temperature were presented. An optimum output power could be set at a certain condition.

Keywords: Thermoelectric Generator (TEG), incinerator, waste heat, optimum power, experimental modeling
