Geothermal Energy: From Theoretical Models to Exploration and Development

51lDleUAFbL._SL160_.jpg

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.

Living Energies: An Exposition of Concepts Related to the Theories of Viktor Schauberger

Why are so many species of plant and animal disappearing? How is it that Earth is losing more fresh water than it is producing? What are the effects of chlorination and fluoridation of water? The answers to these and many more pressing environmental questions are to be found in this remarkable book – the first in-depth examination of the life and work of the brilliant forester, scientist and pioneering inventor, Viktor Schauberger. Schauberger’s insights into Nature pivoted on the essential characteristics of water as a living and pulsating substance that energizes all of life, both organic and inorganic. He frequently asserted, “”Water is a living substance!””–an ideal to which many philosophers have subscribed. With his ground-breaking concepts on energy, biomagnetism and the true function of trees, he showed how a world that exploited its resources rather than cherishing them was doomed to destroy itself. Above all, he demonstrated how Nature’s abundance is the result of a complex interaction of energies that actually create matter, not the other way around as orthodox science believes. For him energy was primary, and physical form the secondary effect.

Introduction to Wind Principles

51g6udXdY7L._SL160_.jpg

The first book on wind energy designed specifically with technicians in mind!  INTRODUCTION TO WIND PRINCIPLES, 1/e covers all aspects of installing and troubleshooting wind turbines, giving technicians the knowledge they need to handle even complex maintenance tasks. Writing clearly and simply, Thomas Kissell explains how wind turbine blades harvest wind energy, and how generators convert shaft turning energy into electricity. He shows how electrical and hydraulic systems control the speed of wind turbine blades, energizing blade pitch and yaw position controls. Mechanical subjects such as gears, transmissions and gearboxes are discussed in detail. Many pictures and diagrams are included, and all math and data is provided: no calculus or other mathematics is required. Some additional features include:

  • Comprehensive, in-depth coverage—including wind turbine installation and troubleshooting, towers, blades, generators, control, and much more 
  • History, background, trends, and demand projections—Provides the context needed to understand the growing role of wind energy Coverage of all parts of vertical and horizontal wind turbines—including small, medium, and large wind turbines
  • Essential electrical coverage—including basic electricity theory, magnetism, motors, generators, PLC controls, and the electrical grid
  • Extensive discussion of mechanical topics
  • Towers, tower designs, and safety- walks through the advantages and disadvantages of each type of tower, discusses the principles of safe tower design and construction, and explains nacelle installation
  • Integration of wind-generated electricity into the grid
