Solar Heating Systems for Houses
The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice. Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favours an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.
Mind over Magma
Mind over Magma chronicles the scientific effort to unravel the mysteries of rocks that solidified on or beneath Earth's surface from the intensely hot, molten material called magma. The first-ever comprehensive history of the study of such igneous rocks, it traces the development of igneous petrology from ancient descriptions of volcanic eruptions to recent work incorporating insights from physical chemistry, isotope studies, and fluid dynamics. Intellectual developments in the field--from the application of scientific methods to the study of rocks to the discovery of critical data and the development of the field's major theories--are considered within their broader geographical, social, a...

Let It Shine
Even as concern over climate change and energy security fuel a boom in solar technology, many still think of solar as a twentieth-century wonder. Few realize that the first photovoltaic array appeared on a New York City rooftop in 1884, or that brilliant engineers in France were using solar power in the 1860s to run steam engines, or that in 1901 an ostrich farmer in Southern California used a single solar engine to irrigate three hundred acres of citrus trees. Fewer still know that Leonardo da Vinci planned to make his fortune by building half-mile-long mirrors to heat water, or that the Bronze Age Chinese used hand-sized solar-concentrating mirrors to light fires the way we use matches and lighters today. With thirteen new chapters, Let It Shine is a fully revised and expanded edition of A Golden Thread, Perlin’s classic history of solar technology, detailing the past forty years of technological developments driving today’s solar renaissance. This unique and compelling compendium of humankind’s solar ideas tells the fascinating story of how our predecessors throughout time, again and again, have applied the sun to better their lives — and how we can too.

The Devil's Wall
Legend has it that twenty miles of volcanic rock rising through the landscape of northern Bohemia was the work of the devil, who separated the warring Czechs and Germans by building a wall. The nineteenth-century invention of the Devil's Wall was evidence of rising ethnic tensions. In interwar Czechoslovakia, Sudeten German nationalists conceived a radical mission to try to restore German influence across the region. Mark Cornwall tells the story of Heinz Rutha, an internationally recognized figure in his day, who was the pioneer of a youth movement that emphasized male bonding in its quest to reassert German dominance over Czech space. Through a narrative that unravels the threads of Rutha'...
