The recent work demonstrates the utilisation of thermoelectric generator (TEG) in design and development of a forced draft thermoelectric generator cookstove (TEG cookstove). The heat energy due to burning of biomass in cookstove is utilised for generation of electrical energy with the help of TEG. A TEG is a device made of semiconductor material converting heat energy into electrical energy. This technology is used to develop a clean combustion cookstove usually for off-grid rural areas. A novel product design has been adopted to develop the TEG cookstove. In the developed design of TEG cookstove, the various topics like design parameters, product technology, materials required including their selection criteria, economic aspects, etc. are discussed in detail along with the power produced from the thermoelectric generator and its functionalities.
