Available in PDF, EPUB and Kindle. Book excerpt: Initially, it had been assumed that a simple ratio computed by dividing the output power by the input power would provide a reliable yardstick for motor power efficiency. The basic idea was sound, for the closer the quotient came to unity, the nearer the motor efficiency would be to 100%. Hence began the so-called "Quest for Unity." However, early "electric engines" were very inefficient, probably delivering no more than 30% of the electrical input power to the output shaft. Therefore, it quickly became evident that not all the applied power was being converted to a mechanical output. Clearly, inefficiencies were involved, and they would have to be accounted for. Until this was complete, the simplified approach to establishing a Factor of Unity could not be realized. What is remarkable, in the history of motor development, is the curious degree of synergy that seems to have accompanied these early pioneering efforts. Between 1839 and 1850 the British Brew Master James Joule conducted an elegant series of experiments, in which he sought to unify electrical, chemical and thermal phenomena by demonstrating their inter-convertibility and their quantitative equivalence. The results of Joule's work were published in the Philosophical Transactions of the Royal Society, with a very impressive title: "On the Mechanical Equivalence of Heat." The contributions of Lord Kelvin must be considered next. His paper, "The Dynamical Equivalent of Heat," published in 1851, contended that energy could be "lost to man irrecoverably; but not lost to the material world". Thomson was thus the first person to understand that all energy changes involve energy dissipation, and losses. During the second half of the nineteenth century Kelvin and other scientists, including Clausius, Rankine, Maxwell and, Boltzmann, continued to develop these ideas. Their combined efforts resulted in the establishment of the Science of Thermodynamics; with Conservation of Energy as its First Law and the Dissipation of Energy as its Second Law. Accordingly, motor researchers were thus made aware of the extreme importance of classifying all known motor losses, and accounting for them with the same degree of accuracy as would be exhibited in the well-established science of corporate book-keeping. Ultimately, such practices would lead to the development of two principle kinds of Efficiency Measurements, both very valuable in all research pertaining to rotating components, but, particularly valuable for developing an understanding of over-unity as a scientific fact. Both efficiency concepts shall be fully explained in this presentation. Simply, this book serves as a definitive guide for those who wish to properly validate their input vs output claims.INCLUDES copies of one of the most significant and important patents in history and a related patent on Jim Murray's Dynaflux Alternator for convenience as it is used as an example in the calculations.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to introduce energy conversion phenomena and materials at multiple levels. With limiting amount of fossil fuels and increasing demand of energy, we are facing the grand challenge of energy sustainability. Energy saving strategies may help to extend the usage of hydrocarbon fossil fuel, but can not solve the problem completely. Renewable energy seems to be the only solution. All the renewable energy sources, solar energy, wind energy, biomass rely on effective energy conversion materials and systems to benefit human beings. Various energy conversion materials and systems including photovoltaic (PV) solar cells and wind turbines have been developed for generating electricity from renewable energy sources such as sunlight and wind. High energy conversion efficiencies are critical for large scale applications of these systems. To understand the fundamentals of energy conversion mechanisms is the very first step. Materials have taken indispensable roles in energy conversions. Therefore, it is necessary to introduce the latest research progress on energy conversion materials to readers at various levels. The content of the book deals with various materials and processing techniques for energy conversions. A comprehensive state-of-the-art review on nanomaterials, related processing technologies and applications will be provided. Considerable effort has been made to elaborate the technological aspect of energy conversion materials, processing and manufacturing these materials.

Book excerpt: Solar Energy Conversion and Photoenergy Systems theme in two volumes is a component of Encyclopedia of Energy Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Any human activity needs energy and renewable energies are always present all over the world. Each location has its own specific renewable potential and it is our task to develop the suitable technologies to profit, at local level, this potential to not only produce the needed energy but also create economic activity and wealth. Solar energy, in particular, has the highest potential among all existing renewable energies and, in the context of the energy, water and climate change global problems mankind will face in the coming years, the substantial integration of solar energy technologies into our societies will an absolute needs in the short to medium term. The number of applications of solar energy is simply huge, covering a very wide range of human activities. Some of these applications are already technically and economically viable, being others still at research or demonstration level. In addition, it has been demonstrated the important benefits solar energy can provide to any area with medium-high solar irradiation level: from sustainability to energy independence, as well as economic development and knowledge creation. Due to this, solar energy development, from photovoltaic to solar thermal or power applications, has been very intense during the last years in all the, so called, “Sun Belt”. There is also the general consensus, at many countries, that we should accelerate the current solar energy pathway, increasing the research efforts to make economically feasible the applications that today are only technically feasible. This effort and the status of most of these applications have been discussed along this paper and within the articles of the topic. The Theme on Solar Energy Conversion and Photoenergy Systems with contributions from distinguished experts in the field, discusses solar energy related technologies and applications, some of which are already in commercial and practical applications and others are under research and testing level. The volumes provide an analysis and discussion about the reasons behind the current efforts of our society, considering both developed and developing countries, to accelerate the introduction of the huge solar energy potential into our normal daily lives. The two volumes also provide some basic information about the solar energy potential, history and the amazing trip of a photon from its creation in the Sun until its arrival to the Earth.
