This second edition is a comprehensive introduction to all aspects of thermoelectric energy conversion. It covers both theory and practice. The book is timely as it refers to the many improvements that have come about in the last few years through the use of nanostructures. The concept of semiconductor thermoelements led to major advances during the second half of the twentieth century, making Peltier refrigeration a widely used technique. The latest materials herald thermoelectric generation as the preferred technique for exploiting low-grade heat. The book shows how progress has been made by increasing the thermal resistivity of the lattice until it is almost as large as it is for glass. It points the way towards the attainment of similar improvements in the electronic parameters. It does not neglect practical considerations, such as the desirability of making thermocouples from inexpensive and environmentally acceptable materials. The second edition was extended to also include recent advances in thermoelectric energy conversion, particularly the production of bulk nanostructures, new materials with higher thermoelectric figures to use the possibility of large scale thermoelectric generation, as part of the worldwide strategy for making better use of energy resources. This book guides the newcomer towards the state of the art and shows the principles for further advancement to those who are already familiar with the subject. The author has been able to draw on his long experience to cover the science and technology in a balanced way while drawing on the expertise of others who have made major contributions to the field.

Small fuel cells for portable applications are important for the security. The portable devices (many electronic and wireless) operated by fuel cells for providing all-day power, are very valuable for the security, for defense and in the war against terrorism. Many companies in NATO and non-NATO countries have concentrated to promote the fuel cell industry. Many universities with industrial partners committed to the idea of working together to develop fuel cells. As tech- logy advanced in the 1980s and beyond, many government organizations joined in spending money on fuel-cell research. In recent years, interest in using fuel cells to power portable electronic devices and other small equipment (cell phones, mobile phones, lab-tops, they are used as micro power source in biological applications) has increased partly due to the promise of fuel cells having higher energy density."

The book analyses a broad range of relevant aspects as the outer space and cyber space domain do not only present analogies but are also strongly interrelated. This may occur on various levels by technologies but also in regard to juridical approaches, each nevertheless keeping its particularities. Since modern societies rely increasingly on space applications that depend on cyber space, it is important to investigate how cyberspace and outer space are connected by their common challenges. Furthermore, this book discusses not only questions around their jurisdictions, but also whether the private space industry can escape jurisdiction by dematerializing the space resource commercial processes and assets thanks to cyber technology. In addition, space and cyberspace policies are analysed especially in view of cyber threats to space communications. Even the question of an extra-terrestrial citizenship in outer space and cyberspace may raise new views. Finally, the interdependence between space and cyberspace also has an important role to play in the context of increasing militarization and emerging weaponization of outer space. Therefore, this book invites questioning the similarities and interrelations between Outer Space and Cyber Space in the same way as it intends to strengthen them.
