Between Air And Electricity

Download or read book Between Air and Electricity written by Cathy van Eck and published by Bloomsbury Publishing USA. This book was released on 2017-02-09 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Earth and Atmospheric Electricity written by Vladimir Shuleikin and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Dirty Electricity written by Samuel Milham MD MPH and published by iUniverse. This book was released on 2012-12-06 with total page 131 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Lights Out written by Jason Makansi and published by John Wiley & Sons. This book was released on 2007-08-24 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: A behind-the-scenes exposure why our electricity system is headed for a state of emergency-and what can be done to head it off Most people don't realize that skyrocketing global energy demand and economic growth severely affect the supply of electricity. Between production (power plants) and delivery is an antiquated, "third-world" transmission grid that is in desperate need of hardening against breakdowns, terrorist attacks, inadequate carrying capacity, and operational obsolescence. And while electricity doesn't hold the headlines or dramatic power of oil, the ability to ensure its uninterrupted supply at a reasonable price is even more essential to global survival and prosperity. Lights Out is today's most detailed, in-depth examination of this largely unreported looming energy crisis. Written by one of the world's top electricity industry experts, this powerful book covers numerous hot button economic and political issues-free markets versus regulation; energy independence versus foreign imports; nuclear power, global warming, and other environmental issues; and much more. Beyond just uncovering and illuminating the problems, however, it proposes a comprehensive road map of technical solutions and regulatory reform from both the production and demand sides of the equation-a framework for rethinking, rebuilding, and enhancing the entire electricity production and delivery infrastructure. Prescriptive and provocative, Lights Out will redefine the simmering debate on how the world can-and must-act now to head off a global catastrophe, one that could eventually wreak even more havoc than the ongoing oil crisis. Jason Makansi is the President of Pearl Street, Inc., a consulting firm; Principal of PS Liquidity Advisors, an advisory service for energy technology companies raising capital; and Executive Director of the Energy Storage Council, a public-policy advocacy organization. A prolific author, respected industry thought leader, and seasoned communicator, Mr. Makansi has been analyzing the technological, business, and regulatory issues in electricity production and delivery for over twenty-five years. He earned a BS in chemical engineering from Columbia University. His earlier books include An Investor’s Guide to the Electricity Economy, also published by John Wiley & Sons, and Managing Steam: An Engineering Guide to Commercial, Industrial, and Utility Systems.
