An important book for anyone contemplating going off grid or just trying to lower their electric bill. Not only is the theory behind a Stirling cycle heat engine explained in detail, but multiple examples are described and explained, some with dramatically different hardware configurations. A Stirling engine exists for just about every occasion and application, and the low cost of production, low threshold of construction skill needed, and low cost of fuel (any heat source will do) renders the engine's inefficiencies completely moot. This is especially true when the engine designs are coupled with solar power in the form of focusing mirrors, heat sinks, and other simple technology. Stirling engines are a technology whose time has come again, and this guide is invaluable for anyone who wants to get in on the ground floor.
