Thermal Solar Desalination
Thermal Solar Desalination: Methods and Systems presents numerous thermal seawater desalination technologies varying from the very simple, easy to construct and operate solar stills, to the more advance membrane and indirect distillation methods. All types of solar thermal desalination technologies are presented in detail to enable readers to comprehend the subject, from design details to enabling further research to be carried out in this area. The various units used in desalination are outlined, along with diagrams of all detailed working principles of desalination methods and systems. The authors consider the economic aspects of these processes, demonstrating successful implementation of desalination units suitable for areas where supplies of fresh water in natural ways is limited or non-existent. - Includes detailed descriptions and design of all types of solar thermal desalination systems - Lists a comprehensive record of seawater and fresh water thermophysical properties required in the design of desalination systems - Contains equations to calculate and analyze the performance of the processes examined and assesses their practicality and application
Solar Energy Index
Solar Energy Index is an index of resources dealing with solar energy, including archival materials from the International Solar Energy Society collection; references to articles in major solar journals; patents and pamphlets; National Technical Information Service reports; unbound conference proceedings; and other assorted reports. Both theoretical and ""how-to-do-it"" publications are well represented. This book places particular emphasis on terrestrial solar thermal and photovoltaic applications of solar energy. Subjects are classified according to physics, terrestrial wind, collectors, space heating and cooling, economics, materials, distillation, thermal-electric power systems, photoele...
La sociedad del salitre
La sociedad que se forjó en el desierto de Atacama en torno a la industria del nitrato, entre los puertos de Pisagua y Taltal, ha sido muy justificadamente observada desde perspectivas que se han vuelto recurrentes: los pioneros y empresarios que dieron origen a esta economía, su importancia para el desarrollo nacional; la reivindicación obrera y sus organizaciones y movimientos sociales; la industria del nitrato y su desenvolvimiento en el mercado internacional; el mercado interno, la propaganda y los tributos salitreros; el trabajo minero y la ficha-salario; el enclave salitrero y su relación con la expansión del Estado-nación; entre otros tópicos. Sin embargo, han quedado en el tintero de los especialistas algunos problemas por investigar y no se trata necesariamente de nuevos temas o de otras temporalidades, sino fundamentalmente de renovados enfoques y perspectivas teóricas de las ciencias sociales que reclaman un diálogo con la historiografía salitrera, para instalar una nueva mirada, más amplia, sobre un período que marcó fuertemente la historia de Chile.
