Abstract: A prototype is developed for thermoelectric power generator module integrated with a double chambered forced draft cookstove. A module of an appropriate rating is chosen for the testing and then power generation is observed. The voltage generated is further stepped-up using a DC-DC step-up converter to run a DC brushless fan of 5V, 0.3A. The fan serves two tasks, first is to cool the one side of thermoelectric power generator and second is to supply the air to the combustion chamber of cookstove. The air is directed to the combustion chamber through a duct which increases the air-to-fuel ratio which helps for a cleaner combustion. A net output of 4W is generated from the thermoelectric power generator.
