Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...
Scientists in Sweden experimentally evaluated a Stirling engine–based Carnot battery (SECB) prototype using low-cost sand as thermal energy storage, aiming to validate ...
Dutch startup BlueHeart Energy is testing its thermoacoustic heat pump engine in residential settings, with a limited European launch expected in spring 2027, followed by gradual scaling. The system ...
