The internal heat of the planet Earth represents an inexhaustible reservoir of thermal energy. This form of energy, known as geothermal energy has been utilized throughout human history in the form of hot water from hot springs. Modern utilization of geothermal energy includes direct use of the heat and its conversion to other forms of energy, mainly electricity. Geothermal energy is a form of renewable energy and its use is associated with very little or no CO2-emissions and its importance as an energy source has greatly increased as the effects of climate change become more prominent. Because of its inexhaustibility it is obvious that utilization of geothermal energy will become a cornerstone of future energy supplies. The exploration of geothermal resources has become an important topic of study as geology and earth science students prepare to meet the demands of a rapidly growing industry, which involves an increasing number professionals and public institutions participating in geothermal energy related projects. This book meets the demands of both groups of readers, students and professionals. Geothermal Energy and its utilization is systematically presented and contains the necessary technical information needed for developing and understanding geothermal energy projects. It presents basic knowledge on the Earth’s thermal regime and its geothermal energy resources, the types of geothermal energy used as well as its future potential and the perspectives of the industry. Specific chapters of the book deal with borehole heat exchangers and with the direct use of groundwater and thermal water in hydrogeothermal systems. A central topic are Enhanced Geothermal Systems (hot-dry-rock systems), a key technology for energy supply in the near future. Pre-drilling site investigations, drilling technology, well logging and hydraulic test programs are important subjects related to the exploration phase of developing Geothermal Energy sites. The chemical composition of the natural waters used as a heat transport medium in geothermal systems can be used as an exploration tool, but chemistry is also important during operation of a geothermal power plant because of potential scale formation and corrosion of pipes and installations, which needs to be prevented. Graduate students and professionals will find in depth information on Geothermal Energy, its exploration and utilization.

Presenting boundary conditions for the economic and environmental utilization of geothermal technology, this is the first book to provide basic knowledge on the topic in such detail. The editor is the coordinator of the European Geothermic Research Initiative, while the authors are experts for the various geological situations in Europe with high temperature reservoirs in shallow and deep horizons. With its perspectives for R&D in geothermic technology concluding each chapter, this ready reference will be of great value to scientists and decision-makers in research and politics, as well as those giving courses in petroleum engineering, for example.

The frontier represented by the near solar system confronts humanity with intriguing challenges and opportunities. With the inception of the Human Exploration and Development of Space (HEDS) enterprise in 1995, NASA has acknowledged the opportunities and has accepted the very significant challenges. Microgravity Research in Support of Technologies for the Human Exploration and Development of Space and Planetary Bodies was commissioned by NASA to assist it in coordinating the scientific information relevant to anticipating, identifying, and solving the technical problems that must be addressed throughout the HEDS program over the coming decades. This report assesses scientific and related technological issues facing NASA's Human Exploration and Development of Space endeavor, looking specifically at mission enabling and enhancing technologies which, for development, require an improved understanding of fluid and material behavior in a reduced gravity environment.

A bibliography of Utah geothermal references through 1984. These references which directly pertain to a geothermal resources are annotated. The annotations are intended to inform the reader of the information contained in the article, not to summarize the results. Accompanying the bibliography is a list and description of geothermal projects and commercial geothermal developments in Utah from 1966 to the present that have been wholly or partially funded through Federal or State programs. The references listed in the project descriptions are keyed to the bibliography. Most of this work is by government agencies or universities. Private or industry-funded geothermal developments are not listed. The references are indexed geographically either under 1.) United States (national studies), 2.) regional – western United States or physiographic province, 3.) Utah – statewide and regional, or 4.) county. Reports concerning a particular hot spring or thermal area are listed under both the thermal area and the county names.
