| fastest way to extract gold from electronics: High Tech Trash Elizabeth Grossman, 2006-05-06 The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients. High Tech Trash is a wake-up call to the importance of the e-waste issue and the health hazards involved. Americans alone own more than two billion pieces of high tech electronics and discard five to seven million tons each year. As a result, electronic waste already makes up more than two-thirds of the heavy metals and 40 percent of the lead found in our landfills. But the problem goes far beyond American shores, most tragically to the cities in China and India where shiploads of discarded electronics arrive daily. There, they are recycled-picked apart by hand, exposing thousands of workers and community residents to toxics. As Grossman notes, This is a story in which we all play a part, whether we know it or not. If you sit at a desk in an office, talk to friends on your cell phone, watch television, listen to music on headphones, are a child in Guangdong, or a native of the Arctic, you are part of this story. The answers lie in changing how we design, manufacture, and dispose of high tech electronics. Europe has led the way in regulating materials used in electronic devices and in e-waste recycling. But in the United States many have yet to recognize the persistent human health and environmental effects of the toxics in high tech devices. If Silent Spring brought national attention to the dangers of DDT and other pesticides, High Tech Trash could do the same for a new generation of technology's products. |

| fastest way to extract gold from electronics: Op Amps for Everyone Ron Mancini, 2003 The operational amplifier (op amp) is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits. |
| fastest way to extract gold from electronics: Blood and Earth Kevin Bales, 2016-01-19 For readers of such crusading works of nonfiction as Katherine Boo’s Beyond the Beautiful Forevers and Tracy Kidder’s Mountains Beyond Mountains comes a powerful and captivating examination of two entwined global crises: environmental destruction and human trafficking—and an inspiring, bold plan for how we can solve them. A leading expert on modern-day slavery, Kevin Bales has traveled to some of the world’s most dangerous places documenting and battling human trafficking. In the course of his reporting, Bales began to notice a pattern emerging: Where slavery existed, so did massive, unchecked environmental destruction. But why? Bales set off to find the answer in a fascinating and moving journey that took him into the lives of modern-day slaves and along a supply chain that leads directly to the cellphones in our pockets. What he discovered is that even as it destroys individuals, families, and communities, new forms of slavery that proliferate in the world’s lawless zones also pose a grave threat to the environment. Simply put, modern-day slavery is destroying the planet. The product of seven years of travel and research, Blood and Earth brings us dramatic stories from the world’s most beautiful and tragic places, the environmental and human-rights hotspots where this crisis is concentrated. But it also tells the stories of some of the most common products we all consume—from computers to shrimp to jewelry—whose origins are found in these same places. Blood and Earth calls on us to recognize the grievous harm we have done to one another, put an end to it, and recommit to repairing the world. This is a clear-eyed and inspiring book that suggests how we can begin the work of healing humanity and the planet we share. Praise for Blood and Earth “A heart-wrenching narrative . . . Weaving together interviews, history, and statistics, the author shines a light on how the poverty, chaos, wars, and government corruption create the perfect storm where slavery flourishes and environmental destruction follows. . . . A clear-eyed account of man’s inhumanity to man and Earth. Read it to get informed, and then take action.”—Kirkus Reviews (starred review) “[An] exposé of the global economy’s ‘deadly dance’ between slavery and environmental disaster . . . Based on extensive travels through eastern Congo’s mineral mines, Bangladeshi fisheries, Ghanian gold mines, and Brazilian forests, Bales reveals the appalling truth in graphic detail. . . . Readers will be deeply disturbed to learn how the links connecting slavery, environmental issues, and modern convenience are forged.”—Publishers Weekly “This well-researched and vivid book studies the connection between slavery and environmental destruction, and what it will take to end both.”—Shelf Awareness (starred review) “This is a remarkable book, demonstrating once more the deep links between the ongoing degradation of the planet and the ongoing degradation of its most vulnerable people. It’s a bracing reminder that a mentality that allows throwaway people also allows a throwaway earth.”—Bill McKibben, author of Eaarth: Making a Life on a Tough New Planet |

| fastest way to extract gold from electronics: The Lean Startup Eric Ries, 2011-09-13 Most startups fail. But many of those failures are preventable. The Lean Startup is a new approach being adopted across the globe, changing the way companies are built and new products are launched. Eric Ries defines a startup as an organization dedicated to creating something new under conditions of extreme uncertainty. This is just as true for one person in a garage or a group of seasoned professionals in a Fortune 500 boardroom. What they have in common is a mission to penetrate that fog of uncertainty to discover a successful path to a sustainable business. The Lean Startup approach fosters companies that are both more capital efficient and that leverage human creativity more effectively. Inspired by lessons from lean manufacturing, it relies on “validated learning,” rapid scientific experimentation, as well as a number of counter-intuitive practices that shorten product development cycles, measure actual progress without resorting to vanity metrics, and learn what customers really want. It enables a company to shift directions with agility, altering plans inch by inch, minute by minute. Rather than wasting time creating elaborate business plans, The Lean Startup offers entrepreneurs—in companies of all sizes—a way to test their vision continuously, to adapt and adjust before it’s too late. Ries provides a scientific approach to creating and managing successful startups in a age when companies need to innovate more than ever. |
