Thermoelectric Energy Recovery from Exhaust Systems: Design, Simulation, and Performance Analysis of a Waste-Heat Recovery Prototype
Abstract: In today’s context, energy plays a vital role in environmental development. Unfortunately, most energy strategies that yield immediate benefits often contribute to long-term environmental degradation. The law of conservation of energy states that “Energy cannot be created or destroyed; it can only change from one form to another.” This idea emphasizes the fact that no technological improvement can continue eternally without having negative effects. Every living thing on the world …
