 Background

 Exhaust(waste) heat, which is released into the environment in significant volumes, consumes more than 60% of the primary energy utilized in the world! ! !

→ 75% of the exhaust heat is low-temperature exhaust heat or heat produced below 300℃.
 (High-temperature exhaust heat is commercialized via steam recovery technology. )
Compact and easy-to-use thermoelectric power generation that converts waste heat directly into electricity is gaining popularity as a way to advance the SDGs
