With the advancement of technology and the increasing demand for environmentally friendly energy, the research on new applications of Thermoelectric Generators (TEG) in high-tech fields such as aerospace and rockets has garnered significant attention. TEG is a device that converts temperature differences into electrical energy using the thermoelectric effect. It has advantages such as small size, light weight, noiseless operation, and no pollution, making it promising for widespread application in this field.

In modern aviation technology, aircraft use electrical energy to drive various devices. Due to the limited payload capacity of aircraft, devices that can save electrical energy are extremely valuable. Currently, many components on airplanes (such as generators, hydraulic pumps, and air conditioning) require energy from the engine to operate. If the heat generated by the generator can be used as input for TEG, it can convert thermal energy into electrical energy to drive these components, further reducing reliance on the engine, saving fuel, and lowering emissions.

In addition to aviation, TEG is also widely used in rocket manufacturing. Rockets are special vehicles that need to generate extremely high thrust in a short time, requiring a large amount of fuel. Utilizing electrical energy provided by TEG to replace some of the fuel can achieve lightweight rocket manufacturing and reduce load.

Currently, TEG technology has made significant advancements. The use of various new materials, such as silicon dioxide, nanomaterials, and polymer materials, has greatly improved TEG's performance. Additionally, new structural models for generating plates, thermal management technologies, and improvements in material preparation, output voltage, and power-to-volume ratio have laid the foundation for the widespread application of TEG.

In summary, the research and development prospects for the widespread application of TEG in high-tech fields such as aviation and rockets are very promising. As a device that can convert temperature differences into electrical energy, the use of TEG can reduce energy consumption, promote environmental protection, improve work efficiency, and lower costs, making it one of the future development directions in high-tech fields like aviation and rockets.
