Exploration of thermoelectric materials that are more effective when 3D printed. Ability to rapidly iterate designs based on performance data, leading to continuous improvement in efficiency. Integration of sensors and smart technologies for real-time monitoring and adjustment. Integration with electric vehicle (EV) systems to further enhance energy management. Research into new materials and printing techniques to improve performance and resilience.

Introduction

Economic growth drives increasing energy demand, especially in developing countries. Global energy use is expected to at least double by 2040. Current reliance on fossil fuels causes environmental and economic issues, highlighting the urgent need to expand renewable energy sources, which have vast potential but face technical maturity challenges.

The project aims to develop a system that uses 3D printing to create durable components for capturing and converting vehicle exhaust heat into electrical energy, which can be stored and reused to improve efficiency.

Literature reviews cover waste heat recovery technologies and systems like Rankine cycles and heat exchangers to improve energy conversion and reduce emissions.

Hardware requirements focus on using Arduino microcontrollers and LCD displays for system control and monitoring, with detailed instructions for setup and programming.

Simulation and modeling involve CAD designs of components and CFD analysis using ANSYS Fluent to study airflow, temperature, pressure, and velocity profiles on an aluminum turbine fan operating at high temperature and speed. Results show effective heat dissipation, stable aerodynamic performance, and material suitability for harsh exhaust environments.

Overall, the study confirms the feasibility of harnessing exhaust thermal energy using advanced materials, 3D printing, and optimized aerodynamic designs to improve energy efficiency in vehicles.

Conclusion

It is observed that the wind from the exhaust can work as a very good source of electricity. The wind speed is sometimes more than the natural air speed and hence can generate even more electrical power than what is produced from natural air. As it is discussed earlier that wind from exhaust fan may get dispersed after some time, there should be some kind of directors/connectors that will guide the wind from the exhaust fan directly to wind turbines without getting the average speed of the wind decreased as the velocity of the wind is most important factor in the system. The wasted wind from exhaust fan can be efficaciously utilized to generate power if proper
