This unique monograph contains a comprehensive overview of celestial mechanics, providing the reader with a solid basis on which to build an understanding of the theory of interplanetary flights. The theoretical development is illustrated with a number of practical examples, bringing to bear the author's wealth of experience gained from working of the Soviet space programme. Many examples are taken from current space topics, including the Shoemaker-Levy 9 comet, the flight of Ulysses over the Solar poles, and the Voyagers' tour of the Solar system. Recent theoretical achivements, such as the intriguing problem of chaos in the Solar system, are also covered.
Recent achievements in sunlight concentration techniques have increased the potential of solar power as a viable source of renewable energy. Through its critical analysis of current methods, Photovoltaic Conversion of Concentrated Sunlight provides a comprehensive treatment of the issues involved in the creation of an efficient and cost-effective sustainable power resource. The authors introduce significant new original research and offer an insight into previously inaccessible Russian studies. Logically structured, the text presents both theoretical and practical advances in the field. Features include:<br> * Discussion of fabrication problems for both terrestrial and space photovoltaic installations<br> * Investigation of the impact of resistive losses on the operation of solar cells and new procedures for measuring components of internal resistance<br> * Explanation of the semiconductor physics underlying photovoltaics<br> * Examination of the most efficient concentrator solar cell structures and materials plus exploration of ways to improve cell performance<br> * Original theoretical and experimental results on luminescence phenomena in concentrator cells<br> * Useful measurement techniques for the determination of diagnostic cell parameters<br> * Analysis of energy characteristics of photovoltaic installations with high and low concentration ratios<br> An invaluable asset to industrialists and academics concerned with semiconductors and photovoltaics, this book will also serve environmental scientists through its examination of the problems associated with large-scale use of this ecological technology.
Flight Without Limits Large-Format Edition (Magazine Style) The novel is Science Fiction - a space journey with the freedom to move, to love, to choose, to live. Imagine, traveling in an instant to wherever you want to be! The universe is your playground. Thought becomes expression. This is science fiction indeed. But maybe mentally it shouldn't be. The novel is about a space voyage to Alpha Centauri, the nearest solar system to our own. It starts as a high tech voyage, and then becomes much more than that. It links up with a future that is moving backwards. It also comes upon a present that has no future, but for which a future is created that has no limits. Of course, being able to travel to wherever one may want to be has certain social advantages, and also challenges. Of course, politically, this capability has even greater challenges attached. Some people say that we will never have the capability, to go physically in an instant wherever we want to be. They might be right. But we do have that kind of capability mentally, in the world of science, romance, and spirituality, all of which are threaded through the novel. You may find that when you return, you have left some of the old limits behind. (http: //www.ice-age-ahead-iaa.ca
