This book covers the developments from Pons and Fleischmann to the 2004 Department of Energy review, which was underway at the time of writing. The book is less technical than Mallove's Fire From Ice and Beaudette's Excess Heat, and it appears to be written with both a technical and a nontechnical audience in mind. The authors are clearly passionate about the topic and devote the first few chapters to exploring the various options open to humankind in the way of energy production. In the middle of the book there is a series of chapters on various types of evidence that have turned up which go into some of the main scientists working in the field and some of the better known experiments. In addition to the valuable technical information, the authors have been in touch with many of these scientists and are familiar enough with the history of the last twenty years to provide some interesting anecdotes.
