Nonimaging Optics In Solar Energy

de Joseph O'Gallagher

37,09€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Nonimaging optics is a subdiscipline of optics whose development over the last 3540 years was led by scientists from the University of Chicago and other cooperating individuals and institutions. The approach provides a formalism that allows the design of optical devices that approach the maximum physically attainable geometric concentration for a given set of optical tolerances. This means that it has the potential to revolutionize the design of solar concentrators. In this monograph, the basic practical applications of the techniques of nonimaging optics to solar energy collection and concentration are developed and explained. The formalism for designing a wide variety of concentrator types, such as the compound parabolic concentrator and its many embodiments and variations, is presented. Both advantages and limitations of the approach are reviewed. Practical and economic aspects of concentrator design for both thermal and photovoltaic applications are discussed as well. The whole range of concentrator applications from simple low-concentration nontracking designs to ultrahigh-concentration multistage configurations is covered. Table of Contents: Introduction / CPCs / Practical Design of CPC Thermal Collectors / Practical Design of CPC PV Concentrators / Two-Stage Nonimaging Concentrators for Solar Thermal Applications / Two-Stage Nonimaging Concentrators for Solar PV Applications / Selected Demonstrations of Nonimaging Concentrator Performance / The Importance of Economic Factors in Effective Solar Concentrator Design / Ultrahigh Concentration / Bibliography

Hitting The Wall - A Vision Of A Secure Energy Future

de Richard Caputo

33,11€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Hitting the Wall examines the combination of two intractable energy problems of our age: the peaking of global oil production and the overloading of the atmosphere with greenhouse gases. Both emerge from the overconsumption of fossil fuels and solving one problem helps solve the other. The misinformation campaign about climate change is discussed as is the role that noncarbon energy solutions can play. There are nine major components in the proposed noncarbon strategy including energy efficiency and renewable energy. Economics and realistic restraints are considered and the total carbon reduction by 2030 is evaluated, and the results show that this strategy will reduce the carbon emission in the United States to be on track to an 80% reduction in 2050. The prospects for clean coal and acceptable nuclear are considered, and there is some hope that they would be used in an interim role. Although there are significant technical challenges to assembling these new energy systems, the primary difficulty lies in the political arena. A multigenerational strategy is needed to guide our actions over the next century. Garnering long-term multiadministration coherent policies to put the elements of any proposed strategy in place, is a relatively rare occurrence in the United States. More common is the reversal of one policy by the next administration with counterproductive results. A framework for politically stable action is developed using the framework of energy tribes where all the disparate voices in the energy debate are included and considered in a messy process. This book provides hope that our descendants in the next century will live in a world that would be familiar to us. This can only be achieved if the United States plays an active leadership role in maintaining climatic balance.

Global Warming And The Future Of The Earth

de Robert G. Watts

33,11€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The globally averaged surface temperature of the Earth has increased during the past century by about 0.7°C. Most of the increase can be attributed to the greenhouse effect, the increase in the atmospheric concentration of carbon dioxide that is emitted when fossil fuels are burned to produce energy.The book begins with the important distinction between weather and climate, followed by data showing how carbon dioxide has increased and the incontrovertible evidence that it is caused by burning fossil fuels (i.e., coal, oil, and natural gas). I also address the inevitable skepticism that global warming arouses and offer a number of responses to the global warming skeptics. After dealing with the skeptics, I analyze both the current and future effects of global warming. These future effects are based on scenarios or storylines put forth by the International Institute for Applied Systems Analysis. In closing, I address the controversial (and grim) suggestion that we have already passed the tipping point, which is the time after which, regardless of our future actions, global warming will cause considerable hardship on human society. I intend this book to be approachable for all concerned citizens, but especially students of the sciences and engineering who will soon be in a position to make a difference in the areas of energy and the environment. I have tried to frame the debate in terms of what the engineering community must do to help combat global warming. We have no choice but to think in terms of global environmental constraints as we design new power plants, factories, automobiles, buildings, and homes. The best thing for scientists to do is to present what we know, clearly separating what is known from what is suspected, in a non-apocalyptic manner. If matters are clearly and passionately presented to the public, we must be prepared to accept the will of the people. This presents the scientific community with an enormous responsibility, perhaps unlike any we have had in the past. Contents: Weather and Climate (and a Little History) / Are the Concentrations of Greenhouse Gases in the Atmosphere Increasing? / The Greenhouse Effect and the Evidence of Global Warming / The Skeptics: Are Their Doubts Scientifically Valid / Impacts: The ""So What"" Question / The Bottom Line
