Book Description
Composers and sound artists have explored for decades how to transform microphones and loudspeakers from “inaudible” technology into genuinely new musical instruments. While the sound reproduction industry had claimed perfect high fidelity already at the beginning of the twentieth century, these artists found surprising ways of use – for instance tweaking microphones, swinging loudspeakers furiously around, ditching microphones in all kinds of vessels, or strapping loudspeakers to body parts of the audience. Between air and electricity traces their quest and sets forward a new theoretical framework, providing historic background on technological and artistic development, and diagrams of concert and performance set-ups. From popular noise musician Merzbow to minimalist classic Alvin Lucier, cult instrument inventor Hugh Davies, or contemporary visual artist Lynn Pook – they all aimed to make audible what was supposed to remain silent.

The Earth and Atmospheric Electricity

Book Description
According to the provisions of the surface atmospheric electricity theory, the space charge of the surface air layer owes its origin to ionization by exhaling soil radon. According to field observations, a model representation of relations between hydrogen, methane, radon, and surface atmospheric electricity elements is composed. Bubbles of two volatile gases carry soil radon from a depth of 4-6 m to the near-surface atmosphere. As a consequence, light ions produced by ionization determine polar conductivity of the surface air; light ion aggregation with neutral condensation nuclei produces heavy ions primarily responsible for the atmospheric electric field. This means that the surface atmospheric electricity is determined by local geology and geodynamics.According to the field observations, the radon content in the surface soil layers is at least two orders of magnitude higher than the concentration of ionizer exhalation. A change in the soil radon content of a single percent will lead to a twofold change in the exhalation concentration, i.e., to a twofold change in the polar conductivities and the atmospheric electric field. This means that the surface atmospheric electricity elements will be extremely sensitive to variations in the subvertical carrier gas (hydrogen and methane) flow density.The results of multiple field observations prove the correctness of the above assumptions. The increased soil-atmosphere air exchange above fault zones, the basement top settling area, and the zones of natural or human-made soil loosening leads to an abrupt decrease in the atmospheric electric field and an increase in the polar air conductivity. An increase in the sub-vertical flow density of hydrogen above the ore body cap or methane in the oil field plume inevitably leads to low values of the atmospheric electric field within the deposit boundaries. The effect can be increased by the presence of natural or human-made seismic excitation in geological environments.The industrial level withdrawal of artesian waters is accompanied by a multiple increase in the atmospheric electric field above the area of hydrogeological processes; methane injection into the underground gas storage, industrial disposal of industrial wastewater leads to the opposite effect, i.e., a decrease of the atmospheric electric field. Taking into account the model constructed, complex measurements of surface atmospheric electricity elements--hydrogen and radon--allow for an indirect expression estimate of the soil methane content above the level of (10-6 - 10-5) vol.% and monitoring of the landslide stressed state.

Energy and Civilization

Pages : 564

Book Description
A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

Languages : en
Pages : 131

Book Description
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.

Power Lines

Pages : 335

Book Description
How high energy consumption transformed postwar Phoenix and deepened inequalities in the American Southwest In 1940, Phoenix was a small, agricultural city of sixty-five thousand, and the Navajo Reservation was an open landscape of scattered sheepherders. Forty years later, Phoenix had blossomed into a metropolis of 1.5 million people and the territory of the Navajo Nation was home to two of the largest strip mines in the world. Five coal-burning power plants surrounded the reservation, generating electricity for export to Phoenix, Los Angeles, and other cities. Exploring the postwar developments of these two very different landscapes, Power Lines tells the story of the far-reaching environmental and social inequalities of metropolitan growth, and the roots of the contemporary coal-fueled climate change crisis. Andrew Needham explains how inexpensive electricity became a requirement for modern life in Phoenix—driving assembly lines and cooling the oppressive heat. Navajo officials initially hoped energy development would improve their lands too, but as ash piles marked their landscape, air pollution filled the skies, and almost half of Navajo households remained without electricity, many Navajos came to view power lines as a sign of their subordination in the Southwest. Drawing together urban, environmental, and American Indian history, Needham demonstrates how power lines created unequal connections between distant landscapes and how environmental changes associated with suburbanization reached far beyond the metropolitan frontier. Needham also offers a new account of postwar inequality, arguing that residents of the metropolitan periphery suffered similar patterns of marginalization as those faced in America's inner cities. Telling how coal from Indian lands became the fuel of modernity in the Southwest, Power Lines explores the dramatic effects that this energy system has had on the people and environment of the region.
