Story summary

A thermoacoustic heat pump led by Luo Ercang at the Chinese Academy of Sciences operates without moving parts and outputs 518°F (270°C).
It surpasses the prior 392°F (200°C) limit, marking a major performance upgrade.
The device uses low-grade heat sources, including solar energy and industrial waste, to produce high-grade heat for ceramics and metallurgy.
The innovation aims to boost energy efficiency and cut fossil-fuel use, supporting China's decarbonization goals.
