Paperback. Zustand: Very Good. Are you prepared? A training and reference manual for the great nationwide revival--which has already begun. The Wind and the Rudder: How to Live in the Power of the Spirit without Becoming Weird gives you everything you need to be part of God's current move Many times the wind of God's Spirit moved powerfully through an individual, in a city, or across a nation, only to see healthy, long-lasting revival aborted due to the lack of a strong rudder. This book provides the stabilizing force during times of dramatic renewal and revival. The focus of The Wind and the Rudder is two-fold: 1. To help an ocean of Jesus-followers discover the thrill, the adventure, and the passion of the Spirit-filled life they are called to live.2. To help believers who have experienced the Spirit discover balance, understanding, and a new sense of mission. A great nationwide revival is arriving--you can prepare yourself to absorb the many benefits of this amazing harvest opportunity.…

Hardback. Zustand: Good. In the late 1990s, West Texas was full of rundown towns and pumpjacks, aging reminders of the oil rush of an earlier era. Today, the towns are thriving as 300-foot-tall wind turbines tower above those pumpjacks. Wind energy has become Texas's latest boom, with the Lone Star State now leading the nation. How did this dramatic transformation happen in a place that fights federal environmental policies at every turn? In The Great Texas Wind Rush, environmental reporters Kate Galbraith and Asher Price tell the compelling story of a group of unlikely dreamers and innovators, politicos and profiteers. The tale spans a generation and more, and it begins with the early wind pioneers, precocious idealists who saw opportunity after the 1970s oil crisis. Operating in an economy accustomed to exploiting natural resources and always looking for the next big thing, their ideas eventually led to surprising partnerships between entrepreneurs and environmentalists, as everyone from Enron executives to T. Boone Pickens, as well as Ann Richards, George W. Bush and Rick Perry, ended up backing the new technology. In this down-to-earth account, the authors explain the policies and science that propelled the windcatters to reap the great harvest of Texas wind. They also explore what the future holds for this relentless resource that is changing the face of Texas energy.…

Hardback. Zustand: Very Good. A beginner's guide to wind power and an invitation to experiment with wind and its potential as an energy source. Wind-powered generators are now used worldwide as a reliable source of "green" energy. How does wind create power? What is wind? What scientific characteristics make pinwheels, windmills and wind turbines spin? What makes them turn faster and more efficiently? Will we ever see a day when every home is powered by its own wind generator? This new book answers these critical questions and many more in clear, non-technical language. Wind Power provides 20 unique projects for youth that use, adapt and illustrate the power of the wind. Artist Clive Dobson provides a basic scientific understanding of wind power and the ways in which it can be harnessed for vital tasks that require energy. The book encourages young readers to experiment with wind so they can experience the properties of moving air on various windmill shapes and discover through trial and error what makes them effective for toys, artwork, kinetic power and even for generating electricity. This ideal beginner's guide to the power of the wind offers: Real-life examples of wind power from history and current everyday uses 20 projects for all ages and skill levels, from a simple two-blade pinwheel to a sophisticated six-sail windmill to a modern turbine with airfoil blades Clear illustrations and photographs that complement the step-by-step construction instructions Hands-on experience that provides a clear understanding of scientific principles Inspiration for beginners to experiment with wind Reflections on the modern use of wind power in building a sustainable future The creative challenges in this compact book of projects will inspire future generations to become more self-sufficient.…

Hardback. Zustand: Good. NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT--OVERSTOCK SALE-- Significantly reduced list price A massive, but little-known, facility in Cleveland, Ohio, played a vital role in the U.S. development of jets, in the training of NASA s first astronauts, and in making NASA s first missions beyond Earth orbit possible. Revolutionary Atmosphere tells the story of this obscure giant. Starting life in 1944 as the Altitude Wind Tunnel, it was the first wind tunnel that could study aircraft engines under realistic flight conditions; and it was enormous in its original configuration, it could even accommodate full-size aircraft. The tunnel could not only simulate the high speeds of jet aircraft, like other wind tunnels, but could simulate the pressures and temperatures of higher elevation flight. Creating the frigid temperatures required the world s largest refrigeration system, which the Carrier Corporation designed with innovative accordion-like cooling coils. At the military s request, nearly every type of aircraft engine was tested in the Altitude Wind Tunnel during the 1940s and 1950s. In the late 1950s, when the flight of Sputnik I spurred the National Advisory Committee for Aeronautics (NACA) to become the National Aeronautics and Space Administration (NASA) and change its primary mission to aerospace, the facility changed too.The tunnel was divided into two sealed vacuum chambers, with one chamber completely rewelded to withstand the higher pressures of simulating the vacuum of space. A liquid-nitrogen cold wall was added to simulate the extreme cold of space, and special lamps were added to simulate the intense heat and light of solar radiation outside of Earth s atmosphere. It was renamed the Space Power Chambers and began its second life as two gigantic environmental chambers, or space tanks.After the mid-1970s the facility was no longer used to simulate the environments of space or the upper atmosphere. Parts of it were used for storage, a shop area was used to test electric automobiles, and the Exhauster Building (which had created the vacuum environment for the facility) had a lengthy second career as a visitor center. In 2005 NASA decided to tear the facility down rather than continue the expense of maintaining it. The Altitude Wind Tunnel/Space Power Chambers 65-year history came to an end in 2009 as its last pieces were dismantled and hauled away.
