Book Description
Also called energy scavenging, energy harvesting captures, stores, and uses "clean" energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, "green" resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I−V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.

Book Description
How solar could spark a clean-energy transition through transformative innovation—creative financing, revolutionary technologies, and flexible energy systems. Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless—every hour the sun beams down more energy than the world uses in a year. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim. Innovation can brighten those prospects, Sivaram explains, drawing on firsthand experience and original research spanning science, business, and government. Financial innovation is already enticing deep-pocketed investors to fund solar projects around the world, from the sunniest deserts to the poorest villages. Technological innovation could replace today's solar panels with coatings as cheap as paint and employ artificial photosynthesis to store intermittent sunshine as convenient fuels. And systemic innovation could add flexibility to the world's power grids and other energy systems so they can dependably channel the sun's unreliable energy. Unleashing all this innovation will require visionary public policy: funding researchers developing next-generation solar technologies, refashioning energy systems and economic markets, and putting together a diverse clean energy portfolio. Although solar can't power the planet by itself, it can be the centerpiece of a global clean energy revolution. A Council on Foreign Relations Book

Book Description
Enthusiasts look forward to a time when tiny machines reassemble matter and process information but is their vision realistic? 'Soft Machines' explains why the nanoworld is so different to the macro-world that we are all familar with and shows how it has more in common with biology than conventional engineering.

Book Description
An interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth's thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere's character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man's hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization's well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change.

Book Description
“A prescription for survival in this gorgeously illustrated and accessible guide to the future of farming.” —Albert Bates, author of The Biochar Solution Grow vegetables year-round in a greenhouse powered only by solar energy! Originally developed in China to feed millions, Chinese greenhouses are earth-sheltered, solar-heated, east-west oriented, intelligently glazed, and well-insulated. They have proven highly effective in growing warm-weather vegetables and fruits like green peppers and tomatoes in cold climates through fall, winter, and early spring using passive solar energy as the sole heat source. The Chinese Greenhouse is a full-color comprehensive guide to these passive solar greenhouses for self-sufficiency and growing year-round in soil or aquaponic grow beds with no additional heat. Coverage includes: How to design, build, and operate a Chinese greenhouse How to improve performance via short-term and long-term heat banking How to provide additional heat to make your greenhouse operate even more effectively How to cool the greenhouse during the summer. Become a more self-sufficient gardener, growing and harvesting a variety of fresh fruits and vegetables year-round, with your own Chinese greenhouse. “Wonderfully researched . . . brilliant.” —Jean-Martin Fortier, farmer and author of The Market Gardener, editor of Growers Magazine “Essential reading for pioneers of Chinese greenhouses.” —Pam Dawling, author of The Year-Round Hoophouse and Sustainable Market Farming “Every enthusiastic vegetable farmer dreams of this winter-growing miracle, and Dan shows how to do it.” —Shawna Coronado, author of 101 Organic Gardening Hacks

Book Description
**Four starred reviews!** A farm-working girl with big dreams meets activist Dolores Huerta and joins the 1965 protest for workers’ rights in this tender-hearted novel in verse, perfect for fans of Rita Williams-Garcia and Pam Muñoz Ryan. Lula Viramontes aches to one day become someone whom no one can ignore: a daring ringleader in a Mexican traveling circus. But between working the grape harvest in Delano, California, with her older siblings under dangerous conditions; taking care of her younger siblings and Mamá, who has mysteriously fallen ill; and doing everything she can to avoid Papá’s volatile temper, it’s hard to hold on to those dreams. Then she meets Dolores Huerta, Larry Itliong, and other labor rights activists and realizes she may need to raise her voice sooner rather than later: Farmworkers are striking for better treatment and wages, and whether Lula’s family joins them or not will determine their future.
