• Expansion of Automotive and Aerospace Industries - The automotive and aerospace industries are witnessing a significant shift towards the adoption of thermoelectric generators (TEGs) for waste heat recovery purposes. In both sectors, vehicles and aircraft generate substantial amounts of waste heat during operation, which was previously considered a loss. With the advancements in TEG technology, this waste heat can now be efficiently converted into usable electricity, offering a dual benefit of improving fuel efficiency and reducing emissions.
  
  TEGs play a crucial role in enhancing fuel efficiency in automobiles and aircraft. By capturing and converting waste heat from the engine and exhaust systems into electricity, TEGs can supplement the power requirements of various onboard systems and components. This reduces the load on the primary power source, such as the engine or battery, leading to improved overall fuel economy. The integration of TEGs allows for the optimization of energy usage within the vehicle or aircraft, contributing to more sustainable and environmentally friendly operations.
  
  The use of thermoelectric generators provides an opportunity to mitigate emissions in the automotive and aerospace sectors.
