Advances in Solar Energy, now in its fifth year, is continuing with topics of the main field of solar energy conversion. However, because of the increasing interest in a solar systems approach, we have decided to include the article of Bockris et al., on Hydrogen Technology, which offers interesting aspects of transport and storage of solar energy, as well as the potential for a versatile fuel. The other articles cover the field of photovoltaics, solar energy-related mate rials, wind conversion, solar retrofitting of existing buildings, and new architectural designs in harmony with climate...

Advances in Solar Energy is back on schedule. Volume III contains a number of interesting reviews of the different fields in solar energy conversion. We appreciate the many encouraging comments received after the second volume appeared and have incorporated some of the suggested changes. Even though most of the reviews are invited through our editors, we are always open to suggestion about subjects of importance that are ready for a com prehensive and critical review and have not been recently covered, or about potential authors. I would like to take this opportunity to thank Professor John...

In Volume 6 of the Advances in Solar Energy we have specifically targeted for a review the rich experience of the Power Utilities. Their hands-on experience in a large variety of means to employ solar energy conversion and to evaluate the technical and economical feasibilities is of great importance to their future use. In designing the lay-out for this volume, we wanted to collect all relevant information, including success and failures and wanted to emphasize the lessons learned from each type of experiment. The publication of such a review now has the advantage of a settled experience in...

A number of significant changes have occurred in Advances in Solar Energy since Volume 1 appeared in 1982. The delays in publication of the second volume are the result of reorganization of the American Solar Energy Society, and the negotiation of a new publishing arrangement. Beginning with this volume, Advances is now published jointly by the Society and Plenum Press. The Editorial Board has been enlarged to be more representative of the different fields of solar energy conversion. Production of Advances is being expedited through the use of modern word processing equipment and the 'lEX...

The field of solar energy conversion has become an important discipline with a recognized potential to significantly contribute to the world supply of energy. It is diversified and encompasses a wide variety of disciplines - from mechanical engineering to physics, from biology to architecture, from ocean science to agriculture, from chemistry to atmospheric science, to name some of the major fields. It involves fields which have matured to the engineering aspects, such as the conversion of solar energy into heat or of wind into shaft work. It includes other fields in which more basic science...
