Status of the emerging technology of Stirling machines

The commercialization status of Stirling machines varies from established niche market products to potential products that are in early stages of development. In other words, we are talking about a typical emerging technology. Many organizations are actively pursuing product development based on Stirling machine technology. Stirling machines offer significant performance advantages, but many obstacles remain to be fully resolved, including cost and demonstrated reliability. This article describes the technology upon which Stirling machines are based. Several application areas are then explored, including hot air engines, remote power, solar thermal power, sensor cooling, refrigeration, cogeneration and air-independent propulsion.<
