In this work, an effective way of producing usable amount of electric power from waste heat of conventional kitchen stoves is presented. Here, thermocouple is used for conversion of waste heat into electrical energy which is then amplified, rectified and stored as charge in a rechargeable DC battery. This power can be used later to drive compatible small loads. The method presented here gives a comprehensive idea and necessary conversion circuits to be used for producing electricity from stove heat. The produced power can be used to charge mobile phone or to drive LED bulbs or low power DC appliances using suitable conversion plugs. Bangladesh, a small country of Southeast Asia with population more than 160 million is taken as an example for calculation purpose. The estimated amount of power that can be generated from all the gas stoves in the country is not negligible and can save a significant amount of power. The proposed idea gives a new source of green energy and can contribute in global search for renewable energy.
