Poster summary

A night markets’ hawkers use an electric lamp to light up their stalls. The current practice is by using a petrol electrical generator which had contributed to pollution and gives an additional cost to the hawkers. There is an alternative electric source for those whose cooking is business oriented. This research develops a Water-cooled thermoelectric generator to harvest excess heat from night market cooking activity. A maximum of 2.4 watts DC electric power has been generated using 10 units of TEG connected in series directed into a butane stove using a copper plate and enhanced with a flow of cooled water. This was equivalent to 9.2% efficiency of the heat conversion process. Analysis of the cooling effect showed that an amount of 8.5 kW heat successfully been removed from the cool side of the TEG using forced convection water cooling at 5.55 x 10-5 m3/s flowrate.
