The Geothermal Technology Division (GTD) of the US Department of Energy (DOE) is charged with the lead federal role in the research and development (RandD) of technologies that will assist industry in economically exploiting the nation's vast geothermal resources. The GTD RandD program represents a comprehensive, balanced approach to establishing all forms of geothermal energy as significant contributors to the nation's energy supply. It is structured both to maintain momentum in the growth of the existing hydrothermal industry and to develop long-term options offering the greatest promise for practical applications. The Geothermal Energy Program Summary for Fiscal Year 1988 is a two-volume set designed to be an easily accessible reference to inform the US geothermal industry and other interested parties of the technological advances and progress achieved in the DOE geothermal program as well as to describe the thrust of the current RandD effort and future RandD directions. This volume, Volume II, contains a detailed compilation of each GTD-funded RandD activity performed by national laboratories or under contract to industrial, academic, and nonprofit research institutions. The Program Summary is intended as an important technology transfer vehicle to assure the wide and timely dissemination of information concerning the department's geothermal research.

Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
