Design of Energy Harvesting Prototypes From Waste Heat of Home Chimney Using Thermoelectric Generators

Abstract

In our project we are converting waste thermal energy into productive electrical energy. With an increase in the number of industries day by day, we continuously read about the thermal energy wastage and the harm it is causing to our environment. Efficiently use of energy is of paramount importance. Thus to do our bit for the environment, we chose this as our project topic. The project constitutes conversion of waste energy from smoke to useful voltage that may be used to operate a mobile charger or some other appliances. We have obtained a maximum of 491 mV using 4 thermopiles in series while the food is being cooked at the time interval of 10 minutes after which it became constant. To widen our scope, we further input our obtained voltage to DC-DC booster circuit to boost up the voltage to greater scale with negligible effect on current
