The Energy Of Nature

Energy is crucial for events of every kind, in this world or any other. Without energy, nothing would ever happen. Nothing would move and there would be no life. The sun wouldn't shine, winds wouldn't blow, rivers wouldn't flow, trees wouldn't grow, birds wouldn't fly, and fish wouldn't swim; indeed no material object, living or dead, could even exist. In spite of all this, energy is seldom considered a part of what we call "nature." In The Energy of Nature, E. C. Pielou explores energy's role in nature—how and where it originates, what it does, and what becomes of it. Drawing on a wide range of scientific disciplines, from physics, chemistry, and biology to all the earth sciences, as well as on her own lifelong experience as a naturalist, Pielou opens our eyes to the myriad ways energy and its transfer affect the earth and its inhabitants. Along the way we learn how energy is delivered to the earth from the sun; how it causes weather, winds, and tides; how it shapes the earth through mountain building and erosion; how it is captured and used by living things; how it is stored in chemical bonds; how nuclear energy is released; how it heats the unseen depths of the planet and is explosively revealed in the turmoil of earthquakes and volcanoes; how energy manifests itself in magnetism and electromagnetic waves; how we harness it to fuel human societies; and much more. Filled with fascinating information and and helpful illustrations (hand drawn by the author), The Energy of Nature is fun, readable, and instructive. Science buffs of all ages will be delighted. “A luminous, inquiring, and thoughtful exploration of Earth’s energetics.”—Jocylyn McDowell, Discovery

A comprehensive, systematic, analytically unified, and interdisciplinary treatment of energy in nature and society, from solar radiation and photosynthesis to our fossil fueled civilization and its environmental consequences.

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. “There's no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.

This final volume in the Eco-technology series deals with generation of energy using Nature's enormous potential.

The Energy Evolution, the final volume in the revolutionary Eco-Technology series, contains radical environmentalist Viktor Schauberger's groundbreaking writings on methods for energy generation that harness the enormous potential of Nature. Nature produces energy by slow, cool, implosive means – by a centripetal inward motion, while our present culture uses explosive centrifugal (outwards) movement, which is wasteful and many times less powerful and effective. It also uses up the Earth's resources and pollutes her ecosystems. This volume describes different kinds of energy machines which depend on the principle of implosion: - A spring water-producing machine - A tornado home energy generator - A Klimator which produces mountain-quality air - The biotechnical submarine - A technique for producing power from ocean deeps - A flying saucer prototype which rose at fantastic speed to high altitudes - A perpetual motion suction-based implosion machineOne of the first genuine environmentalists, Schauberger was a pioneering genius who combined keen observation of Nature with intuitive brilliance and a sharp engineer's brain. His work is enjoying a worldwide revival because he was able to convey how an understanding of Nature's subtle energies is essential to our survival. This Fertile Earth contains his innovative theories as well as his very last letters on the subject, providing an alternative analysis of the unharnessed and vital power of Nature. The Eco-Technology series makes available for the first time Viktor Schauberger's original writings and passionate debates. Callum Coats has painstakingly collected, translated and edited the material for what promises to be the most definitive study yet of this extraordinary man's life and work. This Fertile Earth: Table of Contents Introduction - Some Philosophical Aspects of Natural Energies - New Forms of Temperature - New Forms of Motion and Energy - New Views of Electromagnetism - The Nature of Water, its Conduction and Use for Transport - The Air Turbine - Early Developments in Implosion Machines - The Ennoblement of Water - Machines of the Genus – Repulsator - The Klimator - Machines of the Genus – Repulsine - Last Letters from Viktor Schauberger - The Popel Report

Energy, Entropy, and the Flow of Nature presents the essential principles of energetics (thermodynamics) in a straight-forward, easy to understand, and logically-consistent manner. As a student of physical chemistry and as a professor and researcher in biochemistry, physiology, and general biology, the author has seen the problems that arise for students, teachers, and researchers in mastering the laws of thermodynamics. These difficulties can be alleviated by a careful consideration of the historical roots of the ideas involved, and by recognizing that all natural change can be understood as a flow across a gradient of some kind. Part of the effect of every flow is to diminish its own gradient, but the decrease of one gradient can drive an increase in another. The book's mission is to build a solid understanding of the fundamental concepts of energetics and a confidence in going forth into the many areas that the study of energy opens up. In their applications, the laws of energy and entropy can often involve highly challenging problems and calculations, but the fundamental concepts addressed in this book are easy to understand and require relatively little mathematics.

Over the next several decades, as human populations grow, the demand for energy will soar. But renewable energy sources have a large energy sprawl--the amount of land needed to produce energy--which can threaten biodiversity. In Energy Sprawl Solutions, scientists Joseph M. Kiesecker and David Naugle provide a roadmap for preserving biodiversity despite the threats of energy sprawl. Their strategy--development by design--identifies and sets aside land where biodiversity can thrive while consolidating development in areas with lower biodiversity value. This contributed volume features case studies from countries around the world, each describing a different energy sector and the way they have successfully maximized biodiversity protection. This book provides a needed guide for elected officials, industry representatives, NGOs and community groups who have a stake in sustainable energy-development planning.
