Year: 1980 Activities performed during calendar year 1979 for the hardware system development and testing task are presented. The fluidized bed technology was applied to the drying of potato by-products and to the exchange of heat to air in the space heating experiment. Geothermal water was flashed to steam and also used as the prime energy source in the steam distillation of peppermint oil. Geothermal water temperatures as low as 112.8/sup 0/C were utilized to distill alcohol from sugar beet juice, and lower temperature water provided air conditioning through an absorption air conditioning system. These experiments are discussed; EGG-2013 Title: Geothermal direct applications hardware systems development and testing: 1979 summary report Author: Keller, J.G.

  	Citation × Citation Citation Abstract Copy Title: Hot Dry Rock Geothermal Energy Development Program: Annual Report, Fiscal Year 1985 Author: Brown, D.W. Year: 1987 The primary objective for the Hot Dry Rock Program at the Los Alamos National Laboratory during fiscal year 1985 was to complete the Phase 2 reservoir connection and to begin flow testing the resulting reservoir. The connection was achieved through redrilling one well and additional fracturing operations, and progress was made toward developing a detailed understanding of the fractured region through a variety of reservoir interrogation methods. Other accomplishments during the fiscal year included improvement of the high-temperature, inflatable, open-hole packer used to isolate sections of the uncased wellbore in collaboration with the Baker Corporation and the design and fabrication of a high-temperature borehole acoustic televiewer in a cooperative program with a research institute in West Germany. Progress was also made in techniques for the collection and analysis of microseismic data. Reservoir-engineering activities and geochemical studies, as well as the more routine support activities, continued in FY85. 18 refs., 15 figs.

  	Citation × Citation Citation Abstract Copy Title: Non-Electric Applications of Geothermal Energy in Six Alaskan Towns. Final Report, October 1976--November 1977 Author: Farquhar, J. Year: 1977 The potential for direct (non-electric) utilization of local-gradient geothermal energy in six Alaskan towns is summarized. A major objective of this study was to stimulate development and Use of the geothermal resource provided by the earth's average thermal gradient, as opposed to the few anomalies that are typically chosen for geothermal development. Hence, six towns for study were selected as being representative of remote Alaskan conditions, rather than for their proximity to known geothermal resources. The moderate-temperature heat available almost everywhere at depths of two to four kilometers into the earth's mantle could satisfy a major portion of the nation's heating requirements--but the cost must be reduced. It is concluded that a geothermal demonstration in Nome would probably be successful and would promote this objective Title: Non-Electric Applications of Geothermal Energy in Six Alaskan Towns.

Year: 1980 A fluidized-bed dryer was built and operated at the Raft River Geothermal Test Site in south central Idaho to test the feasibility of using low-temperature (145/sup 0/C or lower) geothermal fluids as an energy source for drying operations. The dryer performed successfully on two potato industry waste products that had a solid content of 5 to 13%. The dried product was removed as a sand-like granular material or as fines with a flour-like texture. Test results, observations, and design recommendations are presented. Also presented is an economic evaluation for commercial-scale drying plants using either geothermal low-temperature water or oil as a heat source Title: Fluidized-Bed Potato Waste Drying Experiments at the Raft River Geothermal Test Site Author: Cole, L.T.

  	Citation × Citation Citation Abstract Copy Title: Long-Term Supply Curves for Geothermal Energy - The Impacts of Technology Author: Fassbender, L.L. Year: 1980 Near-term and long-term supply curves are presented for electric applications of geothermal energy. The GEOCOST model was used to determine the present and future energy production costs for the high-temperature and intermediate-temperature hydrothermal resources identified by the USGS The long-term supply curves illustrate the potential shifts in the near-term supply curve which would result from certain technology improvements currently being pursued. Programs with the most significant potential impacts are those which result in large reductions in drilling cost, those which lead to development of commercial high capacity downhole pumps, and those which lead to large increases in the plant capacity factor. Curves were drawn to show the impacts of individual technology improvements and also to show the cumulative impacts of combinations of technological advances expected to be achieved by 1982 and 1985. Successful completion of all the programs evaluated would result in a cumulative cost reduction of $90 billion (not discounted) in electrical generating costs from the identified hydrothermal resources Title: Long-Term Supply Curves for Geothermal Energy - The Impacts of Technology Author: Fassbender, L.L.
