Nanotube-based thermoelectrics open a new pathway to waste-heat energy conversion

Whenever someone asks ChatGPT a question, heat is generated somewhere in the server room—a data center. When an electric vehicle battery generates heat during operation, the heat must be managed continuously. Manufacturing processes also generate large amounts of waste heat, much of which is simply released into the atmosphere. But what if we could convert this waste heat back into electricity? Recently, a research team in Korea brought this possibility one step closer to reality.
