Electricity is the most important secondary energy source, the present production rate, mainly from thermal electric power stations, being of the order of 1.3 TW. However, the total capacity of primary and rechargeable batteries currently in use is the same as the output of the world's power stations. But present battery systems will not meet future needs for the economical storage of large amounts of electrical energy for vehicles, public transport, road levelling, solar energy utilisation, civil video and audio, terrestrial and space communications, etc. Current accumulators based on aqueous acid or alkali systems do not have sufficient output and, moreover, the materials employed (Pb, Cd, Ni) are environmental pollutants that require safe recycling. Further, stocks of these strategic metals are being rapidly depleted. This book discusses actual field results with novel systems, such as rechargeable lithium batteries, zinc/air cells, metal-free accumulators, graphite/carbon devices and others, including fuel cells. The book stresses that a universal electrochemical system is not feasible: the choice of any system must depend on the concrete field of application and must be taken in consideration of a large number of technical, economic and environmental circumstances.

In this volume, we examine the challenges and opportunities created by global migration at the start of the 21st century. Our focus extends beyond economic impact to questions of international law, human rights, and social and political incorporation. We examine immigrant outcomes and policy questions at the global, national, and local levels. Our primary purpose is to connect ethical, legal, and social science scholarship from a variety of disciplines in order to raise questions and generate new insights regarding patterns of migration and the design of useful policy.While the book incorporates studies of the evolution of immigration law globally and over the very long term, as well as considerations of the magnitude and determinants of immigrant flows at the global level, it places particular emphasis on the growth of immigration to the United States in the 1990s and early 2000s and provides new insights on the complex relationships between federal and state politics and regulation, popular misconceptions about the economic and social impacts of immigration, and the status of 'undocumented' immigrants.

For centuries, scientists have been fascinated by the role of the Sun in the Earth's climate system. Recent discoveries, outlined in this book, have gradually unveiled a complex picture, in which our variable Sun affects the climate variability via a number of subtle pathways, the implications of which are only now becoming clear. This handbook provides the scientifically curious, from undergraduate students to policy makers with a complete and accessible panorama of our present understanding of the Sun-climate connection. 61 experts from different communities have contributed to it, which reflects the highly multidisciplinary nature of this topic. The handbook is organised as a mosaic of short chapters, each of which addresses a specific aspect, and can be read independently. The reader will learn about the assumptions, the data, the models, and the unknowns behind each mechanism by which solar variability may impact climate variability. None of these mechanisms can adequately explain global warming observed since the 1950s. However, several of them do impact climate variability, in particular on a regional level. This handbook aims at addressing these issues in a factual way, and thereby challenge the reader to sharpen his/her critical thinking in a debate that is frequently distorted by unfounded claims.
