Performance of a Modified Grill Thermoelectric Generator With Iced-Based ‘Samalamig’ Cooling System

Abstract

Electrical and electronic education researchers and inventors continuously develop different renewable energy resources. Thermal heat is what they have found to be one of the possible sources throughout their thorough experiments and discoveries. From the fundamental knowledge of thermally powered electric generation, the concept and unique design of a grill thermoelectric generator that uses ‘samalamig’ as its cooling system came to light. In this study, we experimented with and tested its performance in producing electricity voltage, supported by related studies, evidence, and theory. Utilizing the developmental and experimental research designs, the researchers produced a grill thermoelectric generator utilizing an aluminum plate as heat transfer with an ice-based 'samalamig' drinks cooling system in a stainless steel pot. The researchers then tested and measured the temperature difference, voltage output, and the temperatures of the final product's heating and cooling systems for 2 minutes with 15 seconds intervals to arrive at a more accurate result. With an average temperature difference of 18.9°C, the generator produced an average actual voltage output of 7.65 volts and reached an average of 24.46 volts with a booster regulator. And while the ice-based 'samalamig' cooling system hovers around its average at 19.35 °C, transferring heat by the aluminum plate loses heat at an average of 24.78°C. These results showed that while the stainless steel pot as a container for the ice-based ‘samalamig’ cooling system was effective and efficient, the aluminum plate still lost significant energy. Despite that, the generator gathered enough temperature difference to produce electricity for powering small appliances.
