In some cases, extremely hot water may weaken magnets, but for the purposes of everyday life, it’s really a non-issue. Do magnets die? Demagnetisation is a slow process […]
Are Stirling engines practical?
Are Stirling engines practical? Applications of the Stirling engine range from mechanical propulsion to heating and cooling to electrical generation systems. For example, a Free Piston Stirling Cooler (FPSC) can convert an electrical energy input into a practical heat pump effect, used for high-efficiency portable refrigerators and freezers. Where are Stirling engines used today? Stirling […]
