Chinese scientists develop efficient, quiet thermoacoustic Stirling generator

South China Morning Post

Chinese scientists have developed a groundbreaking thermoacoustic Stirling generator, producing 102kW from 530°C heat. The 2m prototype operates quietly and efficiently, with a 28% conversion efficiency. It uses high-pressure helium and has a potential lifespan of over a decade. The generator's innovative design integrates a motor converting sound directly into electrical energy. This breakthrough has potential applications in solar thermal and biomass power generation.
