<t>You might want to consider an absorption refrigerator instead; this kind of refrigerator uses a source of heat directly for refrigeration.<br/> <br/> Wikipedia discusses absorption refrigerators, some of which are commercially available. I don't know if any of them are designed to burn methane fo...

<t>There are a lot of industrial processes which generate waste heat. The fact that Stirling engines can be made to run on low temperature differentials has attracted interest in various circles for reclaiming some of that waste heat, however I think the economy of scale tends to make reclamation of...

<t>Joshua,<br/> <br/> I haven't got years of experience to base this answer on, but I think the answer to the first question is yes. The design you're talking about would be called a "double-acting piston" alpha Stirling engine. I think companies have gone for a "free-piston" design instead, which a...

<t>Two issues I can think of are:<br/> <br/> 1. A football field-size collector absorbing as much solar energy as possible will feel a significant push away from the sun. How hard would it be to keep this "satellite" where you want it? If I understand you correctly, you want it to be 1/10 as far fro...

<r>Greetings, community of Stirling Engine enthusiasts!<br/> <br/> I'm a new member of the community. Over the last few months I've<br/> looked at a variety of Stirling Engine designs, with the goal of<br/> designing, evaluating, and hopefully building a solar thermal electric<br/> generator for my ...
