Concentrating solar power (CSP) technology is poised to take its place as one of the major contributors to the future clean energy mix. Using straightforward manufacturing processes, CSP technology capitalises on conventional power generation cycles, whilst cost effectively matching supply and demand though the integration of thermal energy storage. Concentrating solar power technology provides a comprehensive review of this exciting technology, from the fundamental science to systems design, development and applications. Part one introduces fundamental principles of concentrating solar power systems. Site selection and feasibility analysis are discussed, alongside socio-economic and environmental assessments. Part two focuses on technologies including linear Fresnel reflector technology, parabolic-trough, central tower and parabolic dish concentrating solar power systems, and concentrating photovoltaic systems. Thermal energy storage, hybridization with fossil fuel power plants and the long-term market potential of CSP technology are explored. Part three goes on to discuss optimisation, improvements and applications. Topics discussed include absorber materials for solar thermal receivers, design optimisation through integrated techno-economic modelling, heliostat size optimisation, heat flux and temperature measurement technologies, concentrating solar heating and cooling for industrial processes, and solar fuels and industrial solar chemistry. With its distinguished editors and international team of expert contributors, Concentrating solar power technology is an essential guide for all those involved or interested in the design, production, development, optimisation and application of CSP technology, including renewable energy engineers and consultants, environmental governmental departments, solar thermal equipment manufacturers, researchers and academics.

Interest in and knowledge of the techniques utilised to investigate our solar system has been growing rapidly for decades and has now reached a stage of maturity. Therefore, the time has now arrived for a book that provides a cohesive and coherent account of how we have obtained our present knowledge of solar system objects, not including the Sun. Remote and Robotic Investigations of the Solar System covers all aspects of solar system observations: the instruments, their theory, and their practical use both on Earth and in space. It explores the state-of-the-art telescopes, cameras, spacecraft and instruments used to analyse the interiors, surfaces, atmospheres and radiation belts of solar system objects, in addition to radio waves, gamma rays, cosmic rays and neutrinos. This book would be ideal for university students undertaking physical science subjects and professionals working in the field, in addition to amateur astronomers and anyone interested in learning more about our local astronomical neighbours.

In September 2011, the GRAIL mission launched two unmanned spacecraft to the Moon, which entered into lunar orbit on December 31, 2011 and January 1, 2012. They orbited the Moon until December 17, 2012, when they impacted the surface near the Moon’s north pole. This book contains three review articles co-authored by the GRAIL Science Team and Guest Scientists that describe the reasons for the GRAIL mission, the development of the necessary technology, and the design of the mission to acquire the most precise measurements of the lunar gravity field possible today. The book provides a detailed description of the GRAIL mission’s scientific objectives, the instrumentation and its required performance, the complex simulation of the measurement system for determining the gravity field, and the innovative education and public outreach of the mission directed toward middle-school students who could select areas of the Moon for imaging with the onboard MoonKam camera system. This volume is aimed at researchers and graduate students active in solar system science and planetology. Originally published in Space Science Reviews journal, Vol. 178/1, 2013.
