Since the invention of the free-piston Stirling engine in the early 1960’s, Sunpower’s extensive research and development has been applied to the following Sunpower core technologies:

• Stirling engines that produce power from any heat source
• Stirling cryocoolers that use power to move heat

The Benefits of Sunpower Technology section describes why Sunpower technology offers advantages over alternative technologies and/or Sunpower competitors.
