Radiation: What could go wrong? In short, plenty. From Marie Curie carrying around a vial of radium salt because she liked the pretty blue glow to the large-scale disasters at Chernobyl and Fukushima, dating back to the late nineteenth century, nuclear science has had a rich history of innovative exploration and discovery, coupled with mistakes, accidents, and downright disasters. In this lively book, long-time advocate of continued nuclear research and nuclear energy James Mahaffey looks at each incident in turn and analyzes what happened and why, often discovering where scientists went wrong when analyzing past meltdowns. Every incident, while taking its toll, has led to new understanding of the mighty atom—and the fascinating frontier of science that still holds both incredible risk and great promise.

    And he has boiled it down to one key factor: walkability. The very idea of a modern metropolis evokes visions of bustling sidewalks, vital mass transit, and a vibrant, pedestrian-friendly urban core. But in the typical American city, the car is still king, and downtown is a place that's easy to drive to but often not worth arriving at. Making walkability happen is relatively easy and cheap; seeing exactly what needs to be done is the trick. In this essential new book, Speck reveals the invisible workings of the city, how simple decisions have cascading effects, and how we can all make the right choices for our communities. Bursting with sharp observations and real-world examples, giving key insight into what urban planners actually do and how places can and do change, Walkable City lays out a practical, necessary, and eminently achievable vision of how to make our normal American cities great again.

    Structured around a plane journey that sees encounters with substances from water and glue to coffee and wine, Liquid Rules shows how these liquids can bring death and destruction as well as wonder and fascination.From László Bíró's revolutionary pen and Abraham Gesner's kerosene to cutting-edge research on self-repairing roads and liquid computers, Miodownik uses his winning formula of scientific storytelling to bring the everyday to life. He reveals why liquids can flow up a tree but down a hill, why oil is sticky, how waves can travel so far, and how to make the perfect cup of tea. Here are the secret lives of substances.

    But as architect William McDonough and chemist Michael Braungart point out in this provocative, visionary book, such an approach only perpetuates the one-way, "cradle to grave" manufacturing model, dating to the Industrial Revolution, that creates such fantastic amounts of waste and pollution in the first place. Why not challenge the belief that human industry must damage the natural world? In fact, why not take nature itself as our model for making things? A tree produces thousands of blossoms in order to create another tree, yet we consider its abundance not wasteful but safe, beautiful, and highly effective.Waste equals food. Guided by this principle, McDonough and Braungart explain how products can be designed from the outset so that, after their useful lives, they will provide nourishment for something new. They can be conceived as "biological nutrients" that will easily reenter the water or soil without depositing synthetic materials and toxins. Or they can be "technical nutrients" that will continually circulate as pure and valuable materials within closed-loop industrial cycles, rather than being "recycled" -- really, downcycled -- into low-grade materials and uses. Drawing on their experience in (re)designing everything from carpeting to corporate campuses, McDonough and Braungart make an exciting and viable case for putting eco-effectiveness into practice, and show how anyone involved with making anything can begin to do as well.

    

    Reflecting the increasing demand for efficient conversion and control of electrical power, it considers the latest power devices, circuits, and control schemes that continue to extend power electronics technology to new applications areas. Presents material methodically - first establishing the background theory before going on to specific applications. Familiarizes readers with the analysis and operation of various power conversions circuits that have applications at high power levels, and formulates equations that govern the behavior of these circuits. Discusses the application of power electronic devices in uncontrolled and controlled single phase rectifiers, inverters, ac voltage controllers, cycloconverters, and dc choppers, and demonstrates voltage and current waveform analysis for the output, starting with a simple resistive load to more practical inductive loads. Includes many worked examples, basic formulas, and an abundance of illustrations and diagrams.

    It has been developed in response to the need for a text that supports the mastery of this difficult subject.

    It was also a land withered by drought and hunger, and a place where hope and opportunity were hard to find. But William had read about windmills in a book called Using Energy, and he dreamed of building one that would bring electricity and water to his village and change his life and the lives of those around him. His neighbors may have mocked him and called him misala—crazy—but William was determined to show them what a little grit and ingenuity could do.Enchanted by the workings of electricity as a boy, William had a goal to study science in Malawi's top boarding schools. But in 2002, his country was stricken with a famine that left his family's farm devastated and his parents destitute. Unable to pay the eighty-dollar-a-year tuition for his education, William was forced to drop out and help his family forage for food as thousands across the country starved and died.Yet William refused to let go of his dreams. With nothing more than a fistful of cornmeal in his stomach, a small pile of once-forgotten science textbooks, and an armory of curiosity and determination, he embarked on a daring plan to bring his family a set of luxuries that only two percent of Malawians could afford and what the West considers a necessity—electricity and running water. Using scrap metal, tractor parts, and bicycle halves, William forged a crude yet operable windmill, an unlikely contraption and small miracle that eventually powered four lights, complete with homemade switches and a circuit breaker made from nails and wire. A second machine turned a water pump that could battle the drought and famine that loomed with every season.Soon, news of William's magetsi a mphepo—his "electric wind"—spread beyond the borders of his home, and the boy who was once called crazy became an inspiration to those around the world.Here is the remarkable story about human inventiveness and its power to overcome crippling adversity. The Boy Who Harnessed the Wind will inspire anyone who doubts the power of one individual's ability to change his community and better the lives of those around him.

    Along the way, Bryce eviscerates the ethanol scam. Whether the issue is cost, water consumption, or food prices, corn ethanol is one of the longest-running robberies ever perpetrated on American taxpayers.Consumers concerned about peak oil and the future of global energy supplies need to understand that energy security depends on embracing free markets and the realities of interdependence. Gusher of Lies is illuminating, vital reading.

    The authors write: "Oil is the problem. Cars are the solution." We are living in the midst of a Great Awakening in which environmentalists, entrepreneurs, and political leaders are forming new alliances to end our addiction to oil and create new technologies. The days of Big Oil and Big Auto are numbered, according to the authors, who show how we are in the midst of a major transformation from carbon-based energy sources to new fuels and technologies.ZOOM traces the history of the linked industries of oil and automobiles, and how the two have shaped domestic capitalism and the international landscape, creating both progress and peril. They explain how Toyota vanquished American competitors to become the world's largest automobile manufacturer and, more importantly, a leader in hybrid cars using electric power. They take us into the boardrooms of oil executives and show how some are boldly exploring new energy sources while others deny the dangers posed by oil and risk extinction. With wide-ranging analysis and a keen view of the key players in the intersecting worlds of energy and automobiles, authors Iain Carson and Vijay Vaitheeswaran tell the story of what may be the most important challenge facing the industrial world: How to make the transition from the Age of Petroleum to a cleaner and better future.

    In the ancient city of Bhopal, a cloud of toxic gas escaped from an American pesticide plant, killing and injuring thousands of people.

    

    One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.

    How Buildings Learn is a masterful new synthesis that proposes that buildings adapt best when constantly refined and reshaped by their occupants, and that architects can mature from being artists of space to becoming artists of time. From the connected farmhouses of New England to I.M. Pei's Media Lab, from "satisficing" to "form follows funding," from the evolution of bungalows to the invention of Santa Fe Style, from Low Road military surplus buildings to a High Road English classic like Chatsworth—this is a far-ranging survey of unexplored essential territory.More than any other human artifacts, buildings improve with time—if they're allowed to. How Buildings Learn shows how to work with time rather than against it.
