Hi Guys, A friend as emailed this link to me so I thought I pass it on. I absolutely love sterling Engines and I am planning on building one from a few Cans just to see how difficult it is to getting them working. I am very pleased to see that Stirling Engines are getting a bit more main-Stream and if you have any more info about them, like calculations, tips, practical ways of using them, please just let me know. http://www.sandia.gov/news/resources/releases/2004/renew-energy-batt/Sti rling.html Best regards Luis Luis Moreira luis.moreira@jet.uk tel. 01235464615 JET PSU Department UKAEA Culham Division J20/1/55, Culham Science Centre Abingdon Oxfordshire OX14 3DB -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
