Waste-to-energy (WTE) technologies represent a sustainable and eco-friendly approach to bridging the global energy gap while managing waste efficiently. Among these, thermoelectric conversion has emerged as a promising technique for harnessing heat from otherwise wasted sources such as exhaust systems. This project, titled ThermoVolt, demonstrates the conversion of waste heat into usable electrical energy using a thermoelectric (Peltier) module and a multi-stage power processing system.

In this project, a heat source such as an engine exhaust provides the thermal energy that is converted into electrical power using a thermoelectric Peltier plate. The generated power is then conditioned and regulated through a charging circuit, allowing the energy to be stored in a rechargeable battery. The system is equipped with two operational outputs: (1) a DC-DC buck converter to provide stable power for mobile phone charging, and (2) an inverter circuit that converts DC power into AC, which is used to power a bulb for demonstration purposes.

A smart switching mechanism ensures safe and controlled distribution of the stored power. As the temperature difference across the Peltier module increases, so does the output voltage and current, enhancing energy conversion efficiency. Thermoelectric generation is a reversible and reliable method that does not involve moving parts, thus reducing mechanical wear and increasing system longevity.

This project showcases a practical implementation of renewable, non-conventional energy utilization by converting thermal energy into electricity. It highlights the potential of thermoelectric technology for low-power applications such as emergency lighting and portable electronics charging, particularly in remote or off-grid areas where conventional power sources are not readily available.
