Direct Conversion Technology (open access)

Direct Conversion Technology

The overall objective of the Direct Conversion Technology task is to develop an experimentally verified technology base for promising direct conversion systems that have potential application for energy conservation in the end-use sectors. Initially, two systems were selected for exploratory research and advanced development. These are Alkali Metal Thermal-to-Electric Converter (AMTEC) and Two-Phase Liquid Metal MD Generator (LMMHD). This report describes progress that has been made during the first six months of 1992 on research activities associated with these two systems. (GHH)

Four absolute cavity radiometer (pyrheliometer) intercomparisons at New River, Arizona: radiometer standards (open access)

Four absolute cavity radiometer (pyrheliometer) intercomparisons at New River, Arizona: radiometer standards

Four detailed intercomparisons were made for a number of models of cavity-type self-calibrating radiometers (pyrheliometers). Each intercomparison consisted of simultaneous readings of pyrheliometers at 30-second intervals in runs of 10 minutes, with at least 15 runs per intercomparison. Twenty-seven instruments were in at least one intercomparison, and five were in all four. Summarized results and all raw data are provided from the intercomparisons.

Brine chemistry: scaling and corrosion. Geothermal research study in the Salton Sea region of California (open access)

Brine chemistry: scaling and corrosion. Geothermal research study in the Salton Sea region of California

The purpose of this report is to recommend a reasonable program of brine chemistry research that will result in the development of methods for predicting and controlling scale deposition, and in guidelines for the selection of corrosion-resistant construction materials. First, background information, which is necessary for the understanding of the problems of scaling and corrosion in the Salton Sea KGRA, is presented through a review of the history of geothermal exploration and development in the Salton Sea. Second, literature relevant to the geochemistry of the Salton Sea field is reviewed and important results are emphasized. Third, current research efforts directed toward actual power plant construction are summarized and evaluated. Fourth, research which has been proposed but is not currently funded is discussed. Fifth, because silica scaling has been the most troublesome problem in the past, the basic chemistry of silica and its relationship to scaling is discussed. Sixth, recommendations for future research are made in which a fundamental engineering approach is emphasized. In this approach, experiments would be conducted on actual process equipment and detailed chemical analyses would be performed on site in well-equipped field laboratories. 88 references.

Trends in Heavy Oil Production and Refining in California (open access)

Trends in Heavy Oil Production and Refining in California

This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil production and is part of a study being conducted for the US Department of Energy. This report summarizes trends in oil production and refining in Canada. Heavy oil (10{degrees} to 20{degrees} API gravity) production in California has increased from 20% of the state`s total oil production in the early 1940s to 70% in the late 1980s. In each of the three principal petroleum producing districts (Los Angeles Basin, Coastal Basin, and San Joaquin Valley) oil production has peaked then declined at different times throughout the past 30 years. Thermal production of heavy oil has contributed to making California the largest producer of oil by enhanced oil recovery processes in spite of low oil prices for heavy oil and stringent environmental regulation. Opening of Naval Petroleum Reserve No. 1, Elk Hills (CA) field in 1976, brought about a major new source of light oil at a time when light oil production had greatly declined. Although California is a major petroleum-consuming state, in 1989 the state used 13.3 billion gallons of gasoline or 11.5% of US demand but it contributed substantially to the Nation`s energy …

Nuclear electric propulsion for future NASA space science missions (open access)

Nuclear electric propulsion for future NASA space science missions

This study has been made to assess the needs, potential benefits and the applicability of early (circa year 2000) Nuclear Electric Propulsion (NEP) technology in conducting NASA science missions. The study goals are: to obtain the performance characteristics of near term NEP technologies; to measure the performance potential of NEP for important OSSA missions; to compare NEP performance with that of conventional chemical propulsion; to identify key NEP system requirements; to clarify and depict the degree of importance NEP might have in advancing NASA space science goals; and to disseminate the results in a format useful to both NEP users and technology developers. This is a mission performance study and precludes investigations of multitudes of new mission operation and systems design issues attendant in a NEP flight.

Ground Water in the Northeast Part of Twentynine Palms Marine Corps Base, Bagdad Area, California (open access)

Ground Water in the Northeast Part of Twentynine Palms Marine Corps Base, Bagdad Area, California

Purpose and scope: The U.S. Marine Corps conducts training maneuvers in the study area. Lack of a local source of water has severely limited the utilization of the area. In the past, limited quantities of water have been transported to the area by truck or helicopter. The purpose of this study was to determine the feasibility of obtaining a supply of ground water in the area for use when field maneuvers are being conducted. The major effort for this study was concentrated on the part within the Marine Corps base boundary. The study involved the assessment of ground-water quality, ground water in storage, and aquifer characteristics.
