Experimental electrical characterisation of thermoelectric generator using forced convection water cooling / Raihan Abu Bakar...[et al.]

Thermoelectric Generator (TEG) provides unique advantages as compared to other heat engines as it is capable to convert heat to electricity directly without having any moving parts. Furthermore, TEG is compact, simple and noiseless and requires very minimal maintenance. This paper presents an experi...
