In 1981 the author headed an aid project in Bangladesh to develop a Stirling engine to power small rice huller, which could be fuelled by the rice husks produced by this process. Building a low-tech Stirling Engine that will develop 5 hp (3.7 kw) is no mean feat in itself, and whilst the author and his team succeeded in this, the project itself was stopped after 5 years, and the expenditure of nearly a million US dollars, for a variety of reasons, which are described here. This book MUST be read by anyone thinking of saving the world using Stirling engines, both as a caution, but also because, whilst it is not quite a full set of plans, or building instructions, there is enough here that an experienced engineer, who knows his Stirling engines, should be able to build this engine. And commercialisation and development of this technology is approved and encouraged (but not underwater explosive metal forming which the author used)! 129 pages, inc. 25 of metric drawings. 183 photos.
