A guide is a welcome addition on most any journey. So it is with the greatest of all journeys: the journey to God. One of the Church’s most long-standing and fruitful traditions, spiritual direction is an instrument of God’s glory in the world. The act of clearing the way for the Holy Spirit is a delicate yet challenging matter, and one that requires humility, patience, and charity, among other virtues. Through Wind and Waves is a guidebook for those undertaking this important work. It offers wisdom for both the supernatural and the practical elements of spiritual direction. It shows that being a spiritual guide is not simply a matter of prayer and meditation, but one of a firm interior life, genuine friendship, and the daily realities of living one’s life for the Lord. That life will be marked by adventure, since every soul is unique and is led by the Spirit to blaze new paths to holiness. Filled with wisdom from the saints, as well as Jesus’ words in the Gospels, Through Wind and Waves is a valuable resource for those called to lead others into the safe harbor of God’s love. Rev. Francis Fernández-Carvajal holds graduate degrees in both History and Canon Law. Ordained in 1964, he is a priest of the Opus Dei Prelature and the author of many popular spiritual works. His seven-volume series In Conversation with God provides over 500 meditations to be used throughout the liturgical year. It has sold over 2 million copies and has been translated into many languages.

The availability of clean, renewable power is without question going to be the defining challenge and goal of the 21st century, and wind will lead the way. Internationally acclaimed wind energy expert Paul Gipe is as soberly critical of past energy mistakes as he is convincingly optimistic about the future. The overwhelming challenge of transforming our world from one of fossil carbon to one of clean power seems daunting at best—and paralyzingly impractical at worst. Wind Energy Basics offers a solution. Wind power can realistically not only replace the lion’s share of oil-, coal-, and naturalgas– fired electrical plants in the U.S., but also can add enough extra power capacity to allow for most of the cars in the nation to run on electricity. Gipe explains why such a startlingly straightforward solution is eminently doable and can be accomplished much sooner than previously thought—and will have the capacity to resuscitate small and regional economies. Wind Energy Basics offers a how-to for home-based wind applications, with advice on which wind turbines to choose and which to avoid. He guides wind-energy installers through considerations such as renewable investment strategies and gives cautionary tales of wind applications gone wrong. And for the activist, he suggests methods of prodding federal, state, and provincial governments to promote energy independence.

Woelfle traces the history of windmills and how their design and function have changed over times. Includes more than a dozen wind-related activities such as making a wind sock and wind vane. Full color.

Simple experiments give a hands on approach to studyinig sunlight, air temperature, and atmospheric pressure to help explain how events that occur miles about Earth's surface produce different types of weather.

“Nature, rightly questioned, never lies.” —A Manual of Scientific Enquiry, Third Edition, 1859 Scott Huler was working as a copy editor for a small publisher when he stumbled across the Beaufort Wind Scale in his Merriam Webster Collegiate Dictionary. It was one of those moments of discovery that writers live for. Written centuries ago, its 110 words launched Huler on a remarkable journey over land and sea into a fascinating world of explorers, mariners, scientists, and writers. After falling in love with what he decided was “the best, clearest, and most vigorous piece of descriptive writing I had ever seen,” Huler went in search of Admiral Francis Beaufort himself: hydrographer to the British Admiralty, man of science, and author—Huler assumed—of the Beaufort Wind Scale. But what Huler discovered is that the scale that carries Beaufort’s name has a long and complex evolution, and to properly understand it he had to keep reaching farther back in history, into the lives and works of figures from Daniel Defoe and Charles Darwin to Captains Bligh, of the Bounty, and Cook, of the Endeavor. As hydrographer to the British Admiralty it was Beaufort’s job to track the information that ships relied on: where to lay anchor, descriptions of ports, information about fortification, religion, and trade. But what came to fascinate Huler most about Beaufort was his obsession for observing things and communicating to others what the world looked like. Huler’s research landed him in one of the most fascinating and rich periods of history, because all around the world in the mid-eighteenth and nineteenth centuries, in a grand, expansive period, modern science was being invented every day. These scientific advancements encompassed not only vast leaps in understanding but also how scientific innovation was expressed and even organized, including such enduring developments as the scale Anders Celsius created to simplify how Gabriel Fahrenheit measured temperature; the French-designed metric system; and the Gregorian calendar adopted by France and Great Britain. To Huler, Beaufort came to embody that passion for scientific observation and categorization; indeed Beaufort became the great scientific networker of his time. It was he, for example, who was tapped to lead the search for a naturalist in the 1830s to accompany the crew of the Beagle; he recommended a young naturalist named Charles Darwin. Defining the Wind is a wonderfully readable, often humorous, and always rich story that is ultimately about how we observe the forces of nature and the world around us.

A practical, authoritative guide to the assessment of wind resources for utility-scale wind projects authored by a team of experts from a leading renewable energy consultancy The successful development of wind energy projects depends on an accurate assessment of where, how often, and how strongly the wind blows. A mistake in this stage of evaluation can cause severe financial losses and missed opportunities for developers, lenders, and investors. Wind Resource Assessment: A Practical Guide to Developing a Wind Project shows readers how to achieve a high standard of resource assessment, reduce the uncertainty associated with long-term energy performance, and maximize the value of their project assets. Beginning with the siting, installation, and operation of a high-quality wind monitoring program, this book continues with methods of data quality control and validation, extrapolating measurements from anemometer height to turbine height, adjusting short-term observations for historical climate conditions, and wind flow modeling to account for terrain and surface conditions. In addition, Wind Resource Assessment addresses special topics such as: Worker safety Data security Remote sensing technology (sodar and lidar) Offshore resource assessment Impacts of climate change Uncertainty estimation Plant design and energy production estimatio Filled with important information ranging from basic fundamentals of wind to cutting-edge research topics, and accompanied by helpful references and discussion questions, this comprehensive text designed for an international audience is a vital reference that promotes consistent standards for wind assessment across the industry.
