This book was released on 2018-09-24 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: From December 1994 to September 1998, testing with a 2 kW(sub e) Solar Dynamic power system resulted in 33 individual tests, 886 hours of solar heating, and 783 hours of power generation. Power generation ranged from 400 watts to over 2 kW(sub e), and SD system efficiencies have been measured up to 17 per cent, during simulated low-Earth orbit operation. Further, the turbo-alternator-compressors successfully completed 100 start/stops on foil bearings. Operation was conducted in a large thermal/vacuum facility with a simulated Sun at the NASA Lewis Research Center. The Solar Dynamic system featured a closed Brayton conversion unit integrated with a solar heat receiver, which included thermal energy storage for continuous power output through a typical low-Earth orbit. Two power conversion units and three alternator configurations were used during testing. This paper will review the test program, provide operational and performance data, and review a number of technology issues. Shaltens, Richard K. and Mason, Lee S.

Book Synopsis Automotive Stirling Engine Development Project by : William D. Ernst
Download or read book Automotive Stirling Engine Development Project written by William D. Ernst and published by . This book was released on 1997 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the Automotive Stifling Engine (ASE) Development project were to transfer European Stirling engine technology to the United States and develop an ASE that would demonstrate a 30% improvement in combined metro-highway fuel economy over a comparable spark ignition (SI) engine in the same production vehicle. In addition, the ASE should demonstrate the potential for reduced emissions levels while maintaining the performance characteristics of SI engines. Mechanical Technology Incorporated (MTI) developed the ASE in an evolutionary manner, starting with the test and evaluation of an existing stationary Stirling engine and proceeding through two experimental engine designs: the Mod I and the Mod II. Engine technology development resulted in elimination of strategic materials, increased power density, higher temperature and efficiency operation, reduced system complexity, long-life seals, and low-cost manufacturing designs. Mod Ii engine dynamometer tests demonstrated that the engine system configuration had accomplished its performance goals for power (60 kW) and efficiency (38.5%) to within a few percent. Tests with the Mod II installed in a delivery van demonstrated a combined fuel economy improvement consistent with engine performance goals and the potential for low emissions levels. A modified version of the Mod II was identified as a manufacturable ASE design for commercial production. In conjunction with engine technology development, technology transfer proceeded through two ancillary efforts: the Industry Test and Evaluation Program (ITEP) and the NASA Technology Utilization (TU) project. The ITEP served to introduce Stirling technology to industry, and the TU project provided vehicle field demonstrations for thirdparty evaluation in everyday use and accomplished more than 3100 hr and 8,000 miles of field operation. To extend technology transfer beyond the ASE project, a Space Act Agreement between MTI and NASA-Lewis Research Center allowed utilization of project resources for additional development work and emissions testing as part of an industry-funded Stirling Natural Gas Engine program.

Book Synopsis Advances in Concentrating Solar Thermal Research and Technology by : Manuel Blanco
Download or read book Advances in Concentrating Solar Thermal Research and Technology written by Manuel Blanco and published by Woodhead Publishing. This book was released on 2016-11-10 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: After decades of research and development, concentrating solar thermal (CST) power plants (also known as concentrating solar power (CSP) and as Solar Thermal Electricity or STE systems) are now starting to be widely commercialized. Indeed, the IEA predicts that by 2050, with sufficient support over ten percent of global electricity could be produced by concentrating solar thermal power plants. However, CSP plants are just but one of the many possible applications of CST systems. Advances in Concentrating Solar Thermal Research and Technology provides detailed information on the latest advances in CST systems research and technology. It promotes a deep understanding of the challenges the different CST technologies are confronted with, of the research that is taking place worldwide to address those challenges, and of the impact that the innovation that this research is fostering could have on the emergence of new CST components and concepts. It is anticipated that these developments will substantially increase the cost-competiveness of commercial CST solutions and reshape the technological landscape of both CST technologies and the CST industry. After an introductory chapter, the next three parts of the book focus on key CST plant components, from mirrors and receivers to thermal storage. The final two parts of the book address operation and control and innovative CST system concepts. Contains authoritative reviews of CST research taking place around the world Discusses the impact this research is fostering on the emergence of new CST components and concepts that will substantially increase the cost-competitiveness of CST power Covers both major CST plant components and system-wide issues

Available in PDF, EPUB and Kindle. Book excerpt: Safe Passage: Astronaut Care for Exploration Missions sets forth a vision for space medicine as it applies to deep space voyage. As space missions increase in duration from months to years and extend well beyond Earth's orbit, so will the attendant risks of working in these extreme and isolated environmental conditions. Hazards to astronaut health range from greater radiation exposure and loss of bone and muscle density to intensified psychological stress from living with others in a confined space. Going beyond the body of biomedical research, the report examines existing space medicine clinical and behavioral research and health care data and the policies attendant to them. It describes why not enough is known today about the dangers of prolonged travel to enable humans to venture into deep space in a safe and sane manner. The report makes a number of recommendations concerning NASA's structure for clinical and behavioral research, on the need for a comprehensive astronaut health care system and on an approach to communicating health and safety risks to astronauts, their families, and the public.
Book Synopsis Pregnancy-Related Anxiety by : Rachel Dryer
Download or read book Pregnancy-Related Anxiety written by Rachel Dryer and published by Routledge. This book was released on 2021-10-26 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a collective examination of the theoretical, empirical, and clinical perspectives of pregnancy-related anxiety. Pregnancy-related anxiety is a distinct form of anxiety that is experienced by pregnant women and is characterized by pregnancy-specific fears and worries. This form of anxiety has been associated with a range of negative obstetric, neonatal, and maternal outcomes. There has been increased research interest in this form of anxiety, particularly over the last 15 years. The content is organized in three sections. The first section provides a thorough understanding of pregnancy-related anxiety, ranging from its historical development, evidence of its distinctiveness to the antecedents and outcomes of this anxiety for the mother and child. The second section examines key clinical issues around diagnosis and treatment specifically, current diagnosis/screening for this anxiety and approaches for intervention and treatment. The final section considers emerging areas of research such as pertinent issues around culture and acculturation which are key issues in an increasingly multicultural world. Moreover, the effects of pregnancy-related anxiety on the woman’s broader psychosocial functioning are considered with specific chapters on body image and sexual abuse, two key areas of concern. A seminal resource, this book provides a broad examination of the topic from multiple frameworks and perspectives which sets this book apart from other books in print. This book intends to inform and stimulate future research studies, as well as increase awareness and understanding of pregnancy-related anxiety. It is a must-read for researchers, educators, clinicians, and higher education students who care about delivering better support and services to pregnant women, particularly those who are vulnerable and distressed.
Book Synopsis Feed-in Tariffs by : Miguel Mendonça
Download or read book Feed-in Tariffs written by Miguel Mendonça and published by Taylor & Francis. This book was released on 2012-04-27 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: A feed-in tariff is a renewable energy law that obliges energy suppliers to buy electricity produced from renewable resources at a fixed price, usually over a fixed period - even from householders. These legal guarantees ensure investment security, and the support of all viable renewable energy technologies. Supporters argue that the feed-in model, if implemented effectively around the world, would greatly assist the energy revolution that is so desperately required; through CO2 reduction, market creation and development, job creation and improved energy security. Feed-in Tariffs is a concise introduction to feed-in laws, examining the experience of countries that have implemented this model. The author argues that the policy should be implemented anywhere with a suitable national power grid infrastructure, and identifies variations on the policy for those areas without. Alternative models and support schemes are examined to provide policy makers with the information required to consider the implementation of feed-in tariffs, and to introduce the concept to renewable energy technology manufacturers, producers, investors and supporters. With a foreword by Hermann Scheer. Published with the World Future Council.
