Gordon Tully presents a simplified approach to the analysis of solar energy systems. The book is aimed at people who do not possess the technical knowledge to develop or utilize sophisticated numerical models, but on the other hand, who want to go beyond the simple arm waving and rules of thumb presented in much of the non-technical literature. Gordon starts out asking a rather interesting question: "Have we reached a magic day when energy produced by solar heaters equals the energy available by burning the paper written about them?". His addition to the paper pile is divided into ten chapters. The first chapter briefly describes the modes of operation of a simple solar heating system presented from the "sun-pulse" viewpoint. A "sun-pulse" is the rise and fall of solar radiation intensity over a one day cycle. A solar energy system is considered to receive a series of these pulses (one per day) and the solar designer seeks to utilize these pulses to meet continuous or periodic loads. Chapters 2--4 deal with the nature of the "sunpulse" and methods of collection, Chapter 5 discusses basic principles of heat transfer, and Chapters 6-9 are concerned with system optimization. Chapter 10 deals solely with a drain down solar heating system. The book contains a great deal of information commonly available in the solar literature. It covers both architectural considerations and basic engineering principles. Systems covered include both active and passive solar heating and solar water heating. This book is recommended for architects and others who do not have a strong technical background in solar energy engineering.

Dr. Agnihotri is an Assistant Professor in the Department of Physics at the Indian Institute of Technology in Delhi and Dr. Gupta is a Senior Scientific Officer in the same institute. This book is part of a series being published by Wiley-Interscience on Alternative Energy. The 1st Chapter deals with the preparation, properties and applications of transparent conducting coatings of solar selective surfaces. A transparent conducting coating (heat mirror) is applied to the inner glass cover plate. The theory, deposition and application of several types of semiconducting film are discussed. Chapter 2 deals with the analysis of collectors for solar thermal applications. The 3rd Chapter describes selective coatings which can improve the performance of photovoltaic devices. Characterization of selective surfaces is the topic of the 4th Chapter, which covers both the theory and experimental techniques of measuring emittance and absorption. Chapter 5 delves into the types of selective surfaces we tend to be more familiar with, such as black nickel, black copper, black chrome, copper sulfide, and so forth. I recommend this book to solar energy engineers and scientists as well as for the serious student who wishes to learn more about the theory and practice of solar selective surfaces. Knowledge of heat transfer principles and calculus are prerequisites for understanding the material. I know of no other single publication which contains such a wealth of information on selective coatings for solar applications.
