Stirling 30 kW engine was designed by United Stirling of Sweden for non-solar applications. Each engine part, component and assembly was examined and evaluated to determine the costs of its material and the method of manufacture based on specific annual production volumes. Cost estimates are presented for both the Stirling and Brayton engines in annual production volumes of 1,000, 25,000, 100,000, and 400,000. At annual production volumes above 50,000 units, the costs of both engines are similar, although the Stirling engine costs are somewhat lower. It was concluded that modifications to both the Brayton and Stirling engine designs could reduce the estimated costs. Show Less
