The Stirling engine is quiet and vibration-free, therefore no vibrations are transmitted to the hull, making the submarine silent in the water and hence extremely difficult to locate. The best so far recorded is 32% which is still high for solar conversion. .main-wrapper { Explaining the features of the new Stirling engine, Global Times claimed The prototype ran at a rated power of 320 kilowatts with a power conversion efficiency of 40 percent In comparison, the Stirling engine used on the Swedish Navy's Gotland submarines is rated at 75KW.
