After the devastating tsunami in 2011, DYIers in Japan built their own devices to detect radiation levels, then posted their finding on the Internet. Right now, thousands of people worldwide are tracking environmental conditions with monitoring devices they’ve built themselves. You can do it too! This inspiring guide shows you how to use Arduino to create gadgets for measuring noise, weather, electromagnetic interference (EMI), water purity, and more. You’ll also learn how to collect and share your own data, and you can experiment by creating your own variations of the gadgets covered in the book. If you’re new to DIY electronics, the first chapter offers a primer on electronic circuits and Arduino programming.Use a special microphone and amplifier to build a reliable noise monitor Create a gadget to detect energy vampires: devices that use electricity when they’re “off” Examine water purity with a water conductivity device Measure weather basics such as temperature, humidity, and dew point Build your own Geiger counter to gauge background radiation Extend Arduino with an Ethernet shield—and put your data on the Internet Share your weather and radiation data online through Pachube

Producing electricity from the sun using photovoltaic (PV) systems has become a major industry worldwide. But designing, installing and maintaining such systems requires knowledge and training, and there have been few easily accessible, comprehensive guides to the subject.Now, with Photovoltaics: Design and Installation Manual, a world-class solar energy training and education provider—Solar Energy International (SEI)—has made available the critical information to successfully design, install and maintain PV systems. The book contains an overview of photovoltaic electricity and a detailed description of PV system components, including PV modules, batteries, controllers and inverters. It also includes chapters on sizing photovoltaic systems, analyzing sites and installing PV systems, as well as detailed appendices on PV system maintenance, troubleshooting and solar insolation data for over 300 sites around the world. Used worldwide as the textbook in SEI’s PV Design & Installation workshops, topics covered include:The basics of solar electricityPV applications and system componentsSolar site analysis and mountingStand-alone and PV/generator hybrid system sizingUtility-interactive PV systemsComponent specification, system costs and economicsCase studies and safety issuesPhotovoltaics guarantees that those wanting to learn the skills of tapping the sun’s energy can do so with confidence.Solar Energy International (SEI) has the nonprofit mission to respond to the need for renewable energy education. Based in Carbondale, Colorado, and active around the world, SEI is a link between people and renewable energy resources, providing information, education and training to people who want to shape a sustainable future. SEI is recognized by the National Board of Certified Energy Practitioners (NABCEP) as dedicated independent provider of PV training programs that may be used toward attaining PV certification. Also, SEI is recognized as an Accredited Institution to offer PV training by the Institute for Sustainable Power (ISP).

Over the past twenty years considerable public attention has been focused on the decline of marine fisheries, the sustainability of world fish production, and the impacts of fishing on marine ecosystems. Many have voiced their concerns about marine conservation, as well as the sustainable and ethical consumption of fish. But are fisheries in danger of collapse? Will we soon need to find ways to replace this food system? Should we be worried that we could be fishing certain species to extinction? Can commercial fishing be carried out in a sustainable way? While overblown prognoses concerning the dire state of fisheries are plentiful, clear scientific explanations of the basic issues surrounding overfishing are less so - and there remains great confusion about the actual amount of overfishing and its ecological impact. Overfishing: What Everyone Needs to Know will provide a balanced explanation of the broad issues associated with overfishing. Guiding readers through the scientific, political, economic, and ethical issues associated with harvesting fish from the ocean, it will provide answers to questions about which fisheries are sustainably managed and which are not. Ray and Ulrike Hilborn address topics including historical overfishing, high seas fisheries, recreational fisheries, illegal fishing, climate and fisheries, trawling, economic and biological overfishing, and marine protected areas. In order to illustrate the effects of each of these issues, they will incorporate case studies of different species of fish. Overall, the authors present a hopeful view of the future of fisheries. Most of the world's fisheries are not overfished, and many once overfished stocks are now rebuilding. In fact, we can learn from the management failures and successes to ensure that fisheries are sustainable and contribute to national wealth and food security. Concise and clear, this book presents a compelling "big picture" of the state of oceans and the solutions to ending overfishing.

Originally published to wide acclaim, this lively, cleverly illustrated essay on the use and abuse of maps teaches us how to evaluate maps critically and promotes a healthy skepticism about these easy-to-manipulate models of reality. Monmonier shows that, despite their immense value, maps lie. In fact, they must.The second edition is updated with the addition of two new chapters, 10 color plates, and a new foreword by renowned geographer H. J. de Blij. One new chapter examines the role of national interest and cultural values in national mapping organizations, including the United States Geological Survey, while the other explores the new breed of multimedia, computer-based maps.To show how maps distort, Monmonier introduces basic principles of mapmaking, gives entertaining examples of the misuse of maps in situations from zoning disputes to census reports, and covers all the typical kinds of distortions from deliberate oversimplifications to the misleading use of color."Professor Monmonier himself knows how to gain our attention; it is not in fact the lies in maps but their truth, if always approximate and incomplete, that he wants us to admire and use, even to draw for ourselves on the facile screen. His is an artful and funny book, which like any good map, packs plenty in little space."—Scientific American"A useful guide to a subject most people probably take too much for granted. It shows how map makers translate abstract data into eye-catching cartograms, as they are called. It combats cartographic illiteracy. It fights cartophobia. It may even teach you to find your way. For that alone, it seems worthwhile."—Christopher Lehmann-Haupt, The New York Times". . . witty examination of how and why maps lie. [The book] conveys an important message about how statistics of any kind can be manipulated. But it also communicates much of the challenge, aesthetic appeal, and sheer fun of maps. Even those who hated geography in grammar school might well find a new enthusiasm for the subject after reading Monmonier's lively and surprising book."—Wilson Library Bulletin"A reading of this book will leave you much better defended against cheap atlases, shoddy journalism, unscrupulous advertisers, predatory special-interest groups, and others who may use or abuse maps at your expense."—John Van Pelt, Christian Science Monitor"Monmonier meets his goal admirably. . . . [His] book should be put on every map user's 'must read' list. It is informative and readable . . . a big step forward in helping us to understand how maps can mislead their readers."—Jeffrey S. Murray, Canadian Geographic
