Item Focus point: Solar Energy Partnership with Africa : An Inter-disciplinary Research Project(2008) Düren, Michael; Speitkamp, WinfriedIn the summer of 2007 an inter-disciplinary working group was formed at the Justus-Liebig-University to sound out the opportunities and challenges of an energy partnership with Africa. In a series of interdisciplinary lecturesand at a conference in June 2008 this subject was further explored. Additional conferences and workshops, as well as research projects on certain aspects of the subject will follow. Physicists, chemists, geographers, historians,political scientists, economists, and jurists are currently participating. In the following articles several of the participating researchers present questions and possible solutions from their disciplinary perspectives.Item Focus points: Physics - The Future of our Energy Supply : A Scientific Overview(2008) Düren, MichaelWho really wants to sit in the dark, freeze in the winter, and forego modern methods of transportation? Light, heat, refrigeration, machines, and transportation are just a few of the central engineering achievements of oursociety. All of them are only possible because of the constant availability of something that we call energy. In this article, the subject of our society s energy supply will be explored from the scientific point of view in a clearand simply structured way. This examination will lead to a little known and only superficially abstruse idea: Importing electricity from the deserts of Africa.Item Focus pont: Physics - Solar Thermal Power : The Science and Technology of Solar Thermal Power in Africa(2008) Schäfer, DanielEnergy is the most important of resources and the foundation of all human endeavours. The ubiquity and extensive availability of affordable energy provides the basis for the wealth of the technologically developedworld. The energy problem that the world is facing at the beginning of the 21st century is a complex Issue comprised of three facets: availability, economic efficiency and sustainability. How we respond to this problem willdetermine the shape of tomorrow. Paradoxically, that energy source with the greatest sustainable potential is also the least used: our sun. Solar thermal power stations could provide a possible renewable and environmentallysustainable energy source of tomorrow. These scientific, technical and instrumental fundamentals will be addressed in this article.
