13 - Thermoelectric technologies for harvesting energy from pavements
This chapter introduces the thermoelectric technologies for harvesting energy from pavements. It starts by presenting the basic principle of thermoelectric effect known as “Seebeck effect.” It then explains the temperature characteristics of road surface, ambient air, and subgrade. Based on this, pavement-ambient thermoelectric system and pavement-subgrade thermoelectric system are introduced, including system composition, material design, and energy output of indoor and outdoor tests. And the influence of external environment, traffic load, scale effect, thermoelectric generator, etc., on the energy output of pavement thermoelectric system is explained. Then, the effect of the thermoelectric system on the pavement temperature is analyzed. By the end of the chapter, the problems and development of pavement thermoelectric technologies are analyzed and discussed.
