A team of researchers from NASA and Los Alamos National Laboratory have demonstrated a new reactor concept that combines a Stirling engine with modern heat pipe cooling technology to provide a power ...

In the early years of the nineteenth century, steam engines were at work in a variety of practical uses. However, they were still imperfect in many ways. One particular problem were the boilers, that ...

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 ...
