This book was released on 2015-03-04 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although hundreds of stilling basins and energydissipating devices have been designed in conjunction with spillways, outlet works, and canal structures, it is often necessary to make model studies of individual structures to be certain that these will operate as anticipated. The reason for these repetitive tests is that a factor of uncertainty exists regarding the overall performance characteristics of energy dissipators. The many laboratory studies made on individual structures over a period of years have been made by different personnel, for different groups of designers, each structure having different allowable design limitations. Since no two structures were exactly alike, attempts to generalize the assembled data resulted in sketchy and, at times, inconsistent results having only vague connecting links. Extensive library research into the works of others revealed the fact that the necessary correlation factors are nonexistent. To fill the need for up-to-date hydraulic design information on stilling basins and energy dissipators, a research program on this general subject was begun with a study of the hydraulic jump, observing all phases as it occurs in open channel flow. With a broader understanding of this phenomenon it was then possible to proceed to the more practical aspects of stilling basin design. This monograph generalizes the design of stilling basins, energy dissipators of several kinds and associated appurtenances. General design rules are presented so that the necessary dimensions for a particular structure may be easily and quickly determined, and the selected values checked by others without the need for exceptional judgment or extensive previous experience. Proper use of the material in this monograph will eliminate the need for hydraulic model tests on many individual structures, particularly the smaller ones. Designs of structures obtained by following the recommendations presented here will be conservative in that they will provide a desirable factor of safety. However, model studies will still prove beneficial to reduce structure sizes further, to account for nonsymmetrical conditions of approach or getaway, or to evaluate other unusual conditions not described herein.

Book excerpt: When Thomas Edison began wiring New York City with a direct current electricity distribution system in the 1880s, he gave humankind the magic of electric light, heat, and power; in the process, though, he inadvertently opened a Pandoras Box of unimaginable illness and death. Dirty Electricity tells the story of Dr. Samuel Milham, the scientist who first alerted the world about the frightening link between occupational exposure to electromagnetic fields and human disease. Milham takes readers through his early years and education, following the twisting path that led to his discovery that most of the twentieth century diseases of civilization, including cancer, cardiovascular disease, diabetes, and suicide, are caused by electromagnetic field exposure. In the second edition, he explains how electrical exposure does its damage, and how electricity is causing our current epidemics of asthma, diabetes and obesity. Dr. Milham warns that because of the recent proliferation of radio frequency radiation from cell phones and towers, terrestrial antennas, Wi-Fi and Wi-max systems, broadband internet over power lines, and personal electronic equipment, we may be facing a looming epidemic of morbidity and mortality. In Dirty Electricity, he reveals the steps we must take, personally and as a society, to coexist with this marvelous but dangerous technology.

Book excerpt: Still the World's Most Advanced Text on Earth Sheltering and Passive Solar Design! Passive Annual Heat Storage (PAHS) is a method of collecting heat in the summertime, by cooling the home naturally, storing it in the earth naturally, then returning the heat to the home in the winter. It includes extensive use of natural heat flow methods and the arrangement of building materials to direct heat from wherever you get it to wherever you want it, all without using machinery to make it work. With the rising cost of energy, all home builders should become familiar with basic PAHS principles. The goal of Passive Annual Heat Storage is to provide a method of placing building materials and organizing construction so the comfortable environments produced are continuously pleasant. The resulting subterranean home interiors are balanced with the natural environment and are able to extract all of their energy needs from their surroundings without using any commercial energy sources. Thus, there is no longer any need for using mechanical devices or causing any disruption in global ecosystems. Build a home that naturally stays warm in the winter and cool in the summer!

Available in PDF, EPUB and Kindle. Book excerpt: Hacking the Earthship: In Search of an Earth-Shelter that Works for EveryBody is a comprehensive collection of academic and in-the-field research findings on Earthships, combined with practical how-to advice for designing and financing your own truly sustainable earth-sheltered home. Rachel Preston Prinz and contributing authors discuss the history, research, design issues, and evolution of Earthships, drawing on the knowledge of thousands of builders, craftsmen, and designers who have mastered the art of earth sheltering. Then, they walk readers step by step through design, offering a wealth of resources that can inspire, inform, and educate. Within, readers will find the tools needed to understand their place's culture, architecture, and climate... and the ideal building methods for their climate, personality, values, and budget. THE NEW GENERATION OF EARTHSHIP ENTHUSIASTS: • Does not want to cart questionable building materials long distances and call it “green”. • Wants to build locally and naturally… and they want to build it themselves. • Wants their buildings to be cool in summer, warm in winter, the humidity to be predictable and regular; and they want to minimize pests and allergens. • Wants to be able to get a permit and insurance, and resell their homes if they want to; or pass them on if they can. • They want a smaller home that is “just right”… for their budget, time, ability, energy use, and maintenance. • They want to make their home easy to manage, maintain, and get around in, even if they are in a walker or wheelchair. • They want their home to feel like it is made from and relating to the earth: in views, in light, in fresh air, in the ability to grow food, and in a beautiful landscape that supports the home. Finding the balance between all these desires is a delicate and lengthy process of discernment, study, and goal-setting. That is what this book aims to help you do. Chapter 1 THE EARTHSHIP REALITY PROJECT discusses the issues and resolutions of the design. Chapter 2 THE SCIENCE: ACADEMIC RESEARCH AND TIRE OFF-GASSING reviews academic and scientific research on Earthships. Chapter 3 A WAY FORWARD discusses financing and insurance, minimizing waste, managing the build, visioning, and Code requirements. Chapter 4 THE BUILDING’S CONTEXT AND SITE addresses the site and landscape. Chapter 5 DESIGNING FOR THERMAL COMFORT addresses natural, mechanical, and design options for improving thermal performance. Topics covered include passive solar design; thermal mass versus insulation; earth-coupling versus earth-sheltering; thermal and moisture protection; and natural ventilation. Chapter 6 THE STRUCTURAL SYSTEM addresses the ways we can form the building’s structure. Chapter 7 THE ENCLOSURE SYSTEM outlines the construction of the building’s envelope or skin. We discuss traditional earthship building blocks like tire, glass, and can walls, as well as alternative systems like adobe, cob, rammed earth, earthbags, wood block concrete forms, timber frame, log, cordwood, and strawbale buildings. We also cover various roofing options as well as doors and windows. Chapter 8 ROOMS, SPACES, COLORS, & TEXTURES discusses how we can create a home we love. Chapter 9 MECHANICAL SYSTEMS outlines basic mechanical, electrical, and plumbing considerations, especially on-grid systems since those are what make an Earthship most affordable. Chapter 10 IMBUING SPACE WITH SPIRIT addresses psychological and spiritual aspects of design. Chapter 11 CONCLUSION: A NEW SET OF EARTH-SHELTER BUILDING CRITERIA Chapter 12 OVERWHELMED? NEED HELP? discusses some helpful tips if you hire an architect or residential designer . The APPENDICES offer resources and worksheets. Portions of the proceeds will go to our non-profit architectural education programs ARCHITECTURE FOR EVERYBODY and BUILT FOR LIFE.
