This is an account of the many ways in which the Sun affects our planet, how its influence has changed over the last few centuries and millennia, and the extent to which we can predict its future impact. The book is the first to integrate astronomical, geological, climatic and social aspects of the Sun. It includes a topical treatment of solar contribution to global warming, and demonstrates how wild and variable is the so-called Solar Constant. Our nearest star is a complex machine which needs to be treated with caution, and this book will equip every reader with the knowledge that is required to understand the benefits and dangers it can bring.
The world's deserts are sufficiently large that, in theory, covering a fraction of their landmass with PV systems could generate many times the current primary global energy supply. In three parts, this study details the background and concept of VLS-PV, maps out a development path towards the realization of VLS-PV systems and provides firm recommendations to achieve long-term targets. This represents the first study to provide a concrete set of answers to the questions that must be addressed in order to secure and exploit the potential for VLS-PV technology and its global benefits.

"The agricultural sky" is a dominant natural entity that has influenced, interacted with, and guided the evolution of crops, farming practices, and cropping systems. The sky—and all its components—above and near agricultural areas is an important aspect of an agricultural enterprise—as important as soils, water, and crop species. The blue sky above crops that is seemingly clear, tranquil or sometimes filled with clouds, is really a repository of a large number of gases, mineral or organic particulate matter, dust, mist, turbulent wind, innumerable species of micro-organisms, tiny biotic flora/fauna, seeds, insects, etc. The agrarian sky supports complex interactions of biotic and abiot...
A solution to the climate and energy crisis The reversible fuel cell (RFC) described in this volume stores solar energy and thereby makes it continuously available. This can make the building of energy-free homes and all electric transportation a reality. The foldout drawing at the back of this book also describes the detailed design of the world’s first 1,000 megawatt solar-hydrogen power plant. How is this possible? Our planet receives more solar energy in an hour than humans use in a year. In fact, 5% of the Sahara could meet the total energy requirement of mankind. This energy can then be stored and transported in the form of hydrogen. Converting from an exhaustible energy economy to a...

Presents an overview on the different aspects of the energy value chain and discusses the issues that future energy is facing This book covers energy and the energy policy choices which face society. The book presents easy-to-grasp information and analysis, and includes statistical data for energy production, consumption and simple formulas. Among the aspects considered are: science, technology, economics and the impact on health and the environment. In this new edition two new chapters have been added: The first new chapter deals with unconventional fossil fuels, a resource which has become very important from the economical point of view, especially in the United States. The second new cha...
