Year: 1981 The material presented herein constitutes the Final Report prepared by the City of San Bernardino and its two subcontractors Science Applications, Inc. and Coulter Stewart & Associates, Inc. on the Department of Energy's Grant DE-FG03-80SF1l442 entitled, "Feasibility Study for Wastewater Treatment Utilizing Geothermal Energy in San Bernardino." The study team has developed a system for utilizing nearby low temperature geothermal energy to heat two high-rate primary anaerobic digesters at the San Bernardino Wastewater Treatment Plant. The geothermal fluid would replace the methane currently burned to fuel the digesters. A summary of the work accomplished on the feasibility study is presented in Chapter 2, “Summary and Conclusions" Title: Geothermal Heat Use in San Bernadino Wastewater Treatment Plant Final Report Author: Racine, W.

  	Citation × Citation Citation Abstract Copy Title: Heat Pump Economics Author: Higbee, C.V. Year: 1983 In performing a life cycle cost analysis for direct use geothermal applications it has been said many times that keeping capital investment to a minimum improves the economics of the project. It has also been said repeatedly that extracting a maximum delta t improves the economics. With very low temperature (less than 100°F) geothermal fluids, it becomes necessary to install a heat pump for most space heating applications. Needless to say, the purchase of a heat pump drives capital costs up, annual operating costs up, and usually results in a very low delta t extraction from the resource. All these characteristics of heat pump applications tend to make such projects uneconomical. There are always exceptions. One of these exceptions occurs when electrical energy is the only energy alternative and the resource is warm enough to obtain a coefficient of performance (COP) of 3.0 or better Title: Heat Pump Economics Author: Higbee, C.V.

Year: 1984 Geothermal resource development in Klamath Falls increased dramatically with completion of Phase I of the city geothermal heating system in 1982. Phase I can supply 14 government office buildings and 127 homes in two low-income residential areas with heat and hot water. However, Phase I has not been used because of a lack of historical data regarding long-term sustainability of the resource. This lack of technical knowledge has resulted in conflicts over how to use the resource. This report describes both the cumulative scientific knowledge and the conflicts and groups involved, and offers a comprehensive view of geothermal development in Klamath Falls Title: Geothermal Development in Klamath Falls, Oregon Author: Forcella, L.

  	Citation × Citation Citation Abstract Copy Title: The Marysville, Montana Geothermal Project (Revised) Author: McSpadden, W.R. Year: 1974 The object of the Marysville Geothermal Project is to investigate a region of abnormally high geothermal heat flow near Marysville, MT, about 20 miles northwest of Helena. The research should determine the nature and size of the resource, how the energy might be extracted, the potential monetary value of the energy, and how similar resources elsewhere might be located. The heat source was expected to be a granitic pluton or magmatic intrusion, 10,000 to 40,000 years old, with temperatures in the range of 300 to 500°C. Originally it was thought that the pluton was at relatively shallow depths, but at present its depth and exact location are unknown Title: The Marysville, Montana Geothermal Project (Revised) Author: McSpadden, W.R.

The results show that a linear trough, trending northeast--southwest runs beneath the city. The southern boundary is somewhat to the south of the city, the northern boundary was not established. The geoelectric section consists of three layers and the total thickness of the section is in excess of 3 000 m. The resistivities of the second layer are as low as 2.5 ..cap omega.. m. If the salinities are in the region of 7 000 ppm, the resistivities could indicate that water with a temperature of 150/sup 0/C may be found at a depth of 3 000 m.
