Jim Larsen presented a talk about Stirling Engines at Ada's Technical Bookstore in Seattle, Washington on Sunday February 27, 2011. Jim shared some perspectives of the Stirling engine through the years, and then demonstrated many of his Stirling engines for the audience. The store was filled with people who have an interest in Stirling engines. If you are ever in Seattle, stop by Ada's and check it out. It is a great technical bookstore.
