In this book well known authority on hot engines James Rizzo describes, in detail, two working engines built, before 1825 by Robert Stirling, inventor of the hot air engine, to demonstrate its principles. One engine was presented to the University of Edinburgh, and the other, slightly later, to the University of Glasgow.
This book is an important and historic record of two unique survivors from the very earliest days of mechanisation, and a tremendous project book, providing the engineer with full drawings and instructions to recreate these engines in either full size or model form.
