The Problem of Increasing Human Energy


Book Description

NIKOLA TESLA was a gifted electrical and mechanical engineer, and was one of the most influential inventors of the last century. Eventually holding over 700 patents, Tesla worked in a number of fields, including electricity, robotics, radar, and the wireless transmission of energy. His discoveries laid the groundwork for many of the twentieth century’s greatest technological advances. This book contains Tesla’s thoughts on humanity’s relationship with the universe, and also his explanation and scientific extrapolation on the technological advancements embodied in his work. This text, first published in Century Illustrated Magazine in June 1900, is yet another example of the genius of Nikola Tesla.

Geothermal Resources: An Energy Alternative


Book Description

Developments in Economic Geology, 12: Geothermal Resources: An Energy Alternative focuses on the consideration of geothermal resources as alternative energy sources. The publication first elaborates on the energy outlook, basic concepts, and heat transfer. Discussions focus on temperature, heat, and its storage, heat conduction, radiation, and convection, temperatures within the earth and heat flow, volcanoes and plate tectonics, geothermal resource assessment for the U.S., and recoverability from U.S. geothermal resources. The text then ponders on geothermal systems and resources, exploration techniques, and assessment and exploitation. Concerns cover drilling technology, reservoir physics and engineering, geological and hydrological techniques, geochemical techniques, and types of geothermal systems. The book takes a look at the world-wide status of geothermal resource utilization and the Cerro Prieto geothermal field in Mexico, including geothermal manifestations, transportation of steam, and environmental factors and waste disposal. The publication is a valuable reference for alternative energy experts and researchers interested in geothermal energy resources.




Advances in Thermal Energy Storage Systems


Book Description

Thermal energy storage (TES) technologies store thermal energy (both heat and cold) for later use as required, rather than at the time of production. They are therefore important counterparts to various intermittent renewable energy generation methods and also provide a way of valorising waste process heat and reducing the energy demand of buildings. This book provides an authoritative overview of this key area. Part one reviews sensible heat storage technologies. Part two covers latent and thermochemical heat storage respectively. The final section addresses applications in heating and energy systems. - Reviews sensible heat storage technologies, including the use of water, molten salts, concrete and boreholes - Describes latent heat storage systems and thermochemical heat storage - Includes information on the monitoring and control of thermal energy storage systems, and considers their applications in residential buildings, power plants and industry




Geothermal Fluids


Book Description

This book introduces aqueous geochemistry applied to geothermal systems. It is specifically designed for readers first entering into the world of geothermal energy from a variety of scientific and engineering backgrounds, and consequently is not intended to be the last word on geothermal chemistry. Instead it is intended to provide readers with sufficient background knowledge to permit them to subsequently understand more complex texts and scientific papers on geothermal energy. The book is structured into two parts. The first explains how geothermal fluids and their associated chemistry evolve, and shows how the chemistry of these fluids can be used to, deduce information about the resource. The second part concentrates on survey techniques explaining how these should be performed and the procedures which need to be adopted to ensure reliable sampling and analytical data are obtained. A geothermal system requires a heat source and a fluid which transfers the heat towards the surface. The fluid could be molten rock (magma) or water. This book concentrates on the chemistry of the water, or hydrothermal, systems. Consequently, magma-energy systems are not considered. Hot-dry rock (HDR) systems are similarly outside the scope of this text, principally because they contain no indigenous fluid for study. Both magma-energy and HDR systems have potential as energy sources but await technological developments before they can be exploited commercially. Geothermal systems based on water, however, are proven energy resources which have been successfully developed throughout the world.
