Book Description
Solar thermal flat plate collector technology is well established, with a strong manufacturing base already existing in Australia. Flat plate collectors are not widely used for high temperature (greater than 100 deg.C) applications. Take-off of the market is expected after 1985. A recent development by CSIRO Division of Energy Technology is the slat convection suppression device (CSD). It has been shown that North-South slats perform as well as honeycomb structures, and at collector tilt angles greater than 25 deg., the performance is independent of the tilt angle. A prototype high temperature 2m2 collector was designed with an aspect ratio of 12, using FEP Teflon (by DU PONT) Type 50A as the slat material. For such a collector, approximately 23m2 of Teflon is required, at an approximate cost of $40.00. For collectors with aspect ratios of 6 (e.g. retrofit of medium temperature collectors), the additional material cost would be approximately $20.00. The cost of materials will have a greater influence than labour and equipment overheads on the cost of collectors with slat CSD's. Retrofitting of medium temperature collectors with CSD's will not be cost effective, since the installed cost would be increased by approximately 50%. Similarly for collectors manufactured with a CSD (aspect ratio = 6). Based on a typical model of costing for our manufacturing industry, the cost of high temperature collectors with CSD's could be $215m(-2), compared with the current high temperature flat plate collector cost of approximately $135m(-2) The CSIRO flat plate collector with slat CSD is the most cost effective collector for load temperatures in the range of 80 deg.C to 120 deg.C. The temperature range of 80 deg.C - 120 deg.C would mostly suit commercial applications. The market potential has been estimated at a yearly average of 240,000m2 between 1986 and 2000.

Book Description
While strides are being made in the research and development of environmentally acceptable and more sustainable alternative fuels—including efforts to reduce emissions of air pollutants associated with combustion processes from electric power generation and vehicular transportation—fossil fuel resources are limited and may soon be on the verge of depletion in the near future. Measuring the correlation between quality of life, energy consumption, and the efficient utilization of energy, the Handbook of Alternative Fuel Technologies, Second Edition thoroughly examines the science and technology of alternative fuels and their processing technologies. It focuses specifically on environmental, technoeconomic, and socioeconomic issues associated with the use of alternative energy sources, such as sustainability, applicable technologies, modes of utilization, and impacts on society. Written with research and development scientists and engineers in mind, the material in this handbook provides a detailed description and an assessment of available and feasible technologies, environmental health and safety issues, governmental regulations, and issues and agendas for R&D. It also includes alternative energy networks for production, distribution, and consumption. What’s New in This Edition: Contains several new chapters of emerging interest and updates various chapters throughout Includes coverage of coal gasification and liquefaction, hydrogen technology and safety, shale fuel by hydraulic fracturing, ethanol from lignocellulosics, biodiesel, algae fuels, and energy from waste products Covers statistics, current concerns, and future trends A single-volume complete reference, the Handbook of Alternative Fuel Technologies, Second Edition contains relevant information on chemistry, technology, and novel approaches, as well as scientific foundations for further enhancements and breakthroughs. In addition to its purposes as a handbook for practicing scientists and engineers, it can also be used as a textbook or as a reference book on fuel science and engineering, energy and environment, chemical process design, and energy and environmental policy.

Book Description
At the time of ?nalising this second volume of the ?Yearbook on Space Policy? which covers the period mid-2007 to mid-2008, Europe is as visible and strong in the area of space activities as never before. Its space probes are present on the Moon, around Mars, and on Saturn?s Moon Titan, and are chasing asteroids and comets; Ariane V is the most successful commercial launch vehicle; and more and more European space applications satellites are in operation. Finally, with the successful launch of the Columbus Orbital Facility (COF) – the most prominent highlight of this period which is also depicted on the cover of this Yearbook – and the ?rst Automated Transfer Vehicle (ATV), Europe has become a decisive player in human space?ight. This is accompanied by new policy initiatives on the ministerial level which have been bringing the European Space Agency and the European Union steadily closer. Europe?s outstanding development and positioning in the space ?eld is based not only on Europe?s successful engineering and scienti?c capabilities and capacities, but also on the forceful political determination of all European actors to maintain and even further their engagement in the use of outer space. And it is this political determination which provides the focus for this ?Yearbook on Space Policy?. The Yearbook describes and analyses the contexts and contents of space policy. Its primary ?eld of investigation is Europe, but it also covers the whole range of global space activities and their in?uence on European endeavours.
