‘Coal’ and ‘China’ to some extent have become synonymous. China is by far the largest user of coal in the world. In 2016, coal production in China amounted to 3.21 billion tons, about half of the total global coal production. Coal consumption accounts for more than 65% of primary energy consumption in China. The Chinese coal industry greatly contributes to the economic development in China, the second largest economy in the world. However, periodically, ubiquitous images of smog blanketing major Chinese cities are viewed all over the world. Coal combustion is one of the important contributors to smog, which is considered to be a major environmental and human health problem for China and other countries. News stories also highlight the periodic coal mine disasters that kill hundreds of Chinese coal miners annually. The need to address these and other human health, environmental, and mine safety issues and to maximize resource recovery and use justifies a vigorous coal research effort. This book brings together experts on almost every aspect of coal geology, coal production, composition and use of the coal and its by-products, and coal’s environmental and human health impacts. The chapters in this book were originally published in a special issue of the International Geology Review.
When the China Clipper shattered aviation records on its maiden six-day flight from California to the Orient in 1935, the flying boat became an instant celebrity. This lively history by Robert Gandt traces the development of the great flying boats as both a triumph of technology and a stirring human drama. He examines the political, military, and economic forces that drove its development and explains the aeronautical advances that made the aircraft possible. To fully document the story he includes interviews with flying boat pioneers and a dynamic collection of photographs, charts, and cutaway illustrations.
The Gunpowder Epic is one of three planned publications on military technology within Dr Needham's immense undertaking. The discovery of gunpowder in China by the 9th century AD was followed by its rapid applications. It is now clear that the whole development from bombs and grenades to the invention of the metal-barrel hand gun took place in the Chinese culture area before Europeans had any knowledge of the mixture itself. Uses in civil engineering and mechanical engineering were equally important, before the knowledge of gunpowder spread to Europe in the thirteenth and fourteenth centuries. Dr Needham's new work continues to demonstrate the major importance of Chinese science and technology to world history and maintains the tradition of one of the great scholarly works of the twentieth century.
