    The Joint Center for Energy Storage Research: A New Paradigm for Battery Research and Development

    Full text link
    The Joint Center for Energy Storage Research (JCESR) seeks transformational change in transportation and the electricity grid driven by next generation high performance, low cost electricity storage. To pursue this transformative vision JCESR introduces a new paradigm for battery research: integrating discovery science, battery design, research prototyping and manufacturing collaboration in a single highly interactive organization. This new paradigm will accelerate the pace of discovery and innovation and reduce the time from conceptualization to commercialization. JCESR applies its new paradigm exclusively to beyond-lithium-ion batteries, a vast, rich and largely unexplored frontier. This review presents JCESR's motivation, vision, mission, intended outcomes or legacies and first year accomplishments.Comment: 17 pages, 14 figures, 96 reference

    Large solar arrays

    A spectrophotovoltaic converter, a thermophotovoltaic converter, a cassegrainian concentrator, a large silicon cell blanket, and a high flux approach are among the concepts being investigated as part of the multihundred kW solar array program for reducing the cost of photovoltaic energy in space. These concepts involve a range of technology risks, the highest risk being represented by the thermophotovoltaics and spectrophotovoltaics approaches which involve manipulation to of the incoming spectrum to enhance system efficiency. The planar array (solar blanket) has no technology risk and a moderate payback. The primary characteristics, components, and technology concerns of each of these concepts are summarized. An orbital power platform mission in the late 1980's is being used to allow a coherent technology advancement program in order to achieve a ten year life with maintenance at a capital recurring cost of $30/watt based on 1978 dollars

    The recent past, present state-of-the-art, and future needs in the area of large photovoltaic solar arrays are discussed. In the past most attention was focused upon performance whereas in the future most of the effort should go into cost reduction. Suggestions are made regarding possible approaches to reducing cost such as on-orbit maintenance, extended lifetime, solar concentrators, and high-voltage modular concepts

    Within, without: dialogical perspectives on feminism and Islam.

    This paper offers an ontological and literary review of Muslim women’s religious practices across the Muslim ummah, in considering the development of an epistemology of faith and feminism within the Islamic schema. Global examples of faith-based practice are reviewed, where issues of dominant and minority cultures and values refer to how Muslim faith practices are enacted within the local context. The authors use a dyadic, auto-ethnographic methodology to explore their own personal, political and spiritual positioning as feminists from a Muslim, immigrant and secular British background. The significance of women’s spiritual and feminist dimensions in the context of faith, nationhood and embodiment of ideological positions are analysed. Additionally, religious, cultural and the geo-political implications of feminism and Islam are considered regarding identity, culture and tradition, and religious resurgence, together with forms of feminist resistance to religious doctrine. Finally, the search by women for spiritual authority and authenticity is discussed. Keywords: Islam, Muslim, feminist, faith, auto-ethnographi

    Covert research and adult protection and safeguarding: An ethical dilemma?

    Purpose: This paper aims to consider the contentious issue of covert research in studying the social contexts of vulnerable groups. It explores its potential utility in areas where overt strategies may be problematic or denied; and examines and problematises the issue of participant consent. Design/methodology/approach: Using a literature-based review and selected previous studies, the paper explores the uses and abuses of covert research in relation to ethics review proceedings governing social research, with an especial focus on vulnerability. Findings: Findings indicate that although the use of covert research is subject to substantial critique by apparently transgressing the often unquestioned moral legitimacy of informed consent, this carries ethical and practical utility for research related to safeguarding concerns. Arguably covert research enables research access to data likely to reveal abusive and oppressive practices. Research limitations/implications: Covert research assists in illuminating the hidden voices and lives of vulnerable people that may otherwise remain inaccessible. Such research needs to be subject to rigorous ethical standards to ensure that it is both justified and robust. Practical implications: Emphasising the need to consider all angles, questions and positions when addressing the social problem of adult protection and safeguarding. Originality/value: Increasingly social research is treated as being as potentially harmful as medical research. Ethics review tends towards conservative conformity, legitimising methodologies that may serve less social utility than other forms of investigation that privilege the safeguarding of vulnerable people. © Emerald Group Publishing Limited
