Readers 1x-10x are 10 new stories, set at the beginner level (as 1-10). These were requested by teachers to provide children with more practice on simple sounding words before moving on to the next level (11-20) with its many digraphs.Without introducing any new spelling principles, the Readers 1x-10x provide more long words which can be simply sounded out.The printer?s a (a rather than a) is introduced in story 4x.There are hardly any new special words in the 1x-10x series. The basic principles of sounding out are consolidated with more sounding words and longer sounding words.
Helps readers understand and appreciate what the history of wind power can teach us about technology innovation and provides the implications for both wind power today and its future This book takes readers on a journey through the history of wind power in order to show how the technology evolved over the course of the twentieth century and where it may be headed in the twenty-first century. It introduces and examines broad themes such as government funding of wind power, the role of fossil fuels in wind power development, and the importance of entrepreneurs in wind power development. It also discusses the lessons learned from wind power technology innovation and makes them relevant to the understanding of wind power today and in the future. Spanning the entire history of wind power (1888-2018), The Wind Power Story: A Century of Innovation that Reshaped the Global Energy Landscape provides balanced coverage of each decade as well as the important wind power technology innovations that occurred during that time. Compelling from the first page to the last, it offers chapters covering the pioneers of wind power; the age of small wind; wind power in the wake of war; wind power’s use across Europe; government-funded research programs; how Denmark reinvented wind power in the 1970s; the California Wind Rush of the 1980s; wind power’s rise in Spain; America’s wind power starting in the 1990s; India’s wind power path; the wind power surge in China; the globalization of wind power; and much more. In addition, this text: Spans the entire global history of wind power, while weaving together both the historical context and the technical details of wind power innovation Provides historical context for wind power developments and explains the evolution of wind turbine technology in an easy-to-understand manner Discusses the policy, technology, and market evolution of wind power in commonly understood language Offers a review of the surrounding power technology, policy, and market environment throughout the history of wind power A book that both specialists and non-specialists can read in order to understand and appreciate the past, present, and future of wind power technology, The Wind Power Story: A Century of Innovation that Reshaped the Global Energy Landscape will be of great interest to any engineer and any interested readers looking to understand wind power technologies, markets, and policies in one book.
Describes and provides illustrations of the kinds of space exploration that may be done in the near future, and discusses the economic and political implications for the people of the earth
Paolo Ulivi provides a well-paced, rapidly moving, balanced, even-handed account of lunar exploration as a popular history. He covers the unmanned programmes, e.g. Ranger, and other American probes in the late ‘50s and in the later chapters he looks at recent lunar exploration and future plans for the same. It’s a book that will be perfect for an enthusiast or someone coming to the story for the first time, as it does not include excessive technical depth. Uniquely drawing on recently declassified documents, detail of Chinese lunar exploration projects is provided, as well as nuclear lunar weapons of the ‘50s developed by the super powers, Soviet Russia and the United States.
Illustrated with photographs from Soviet Venus and Mars probes, images of spacecraft, diagrams of flight paths and maps of landing sites, this book draws on published scientific papers, archives, memoirs and other material. The text reviews Soviet engineering techniques and science packages, as well the difficulties which ruined several missions. The program’s scientific and engineering legacy is also addressed, within the Soviet space effort as a whole.
