Now here is a real beautiful collection of models. From the far left is his large Stirling Fan called a Lakebreeze, to the right of that is a neat Miser Temperature Differential engine, then another very small Stirling engine. His little lathe is real neat and then his "Beamer" Hot Air Stirling engine, built from plans obtained from Jerry Howell. And finally his little Moriya fan at the right. That's Ralph and Donna in the photo.
