Thermophysical properties of coal liquids. Seventh quarterly technical status report, April 1-June 30, 1981

Description: Measurements of rheological properties have been continued. Measurements at relatively low temperature (450 K) showed that a coarser coal grind shows substantially lower viscosity. It was also shown that coal and solvent obtained from the Fort Lewis plant give slurries of much higher viscosity than slurries from our reference coal and solvent. At higher temperatures (540 K) substantially the same relationships were shown. The effect of solvent-to-coal ratio was also found to be very great. Diff… more

Methodology and basic algorithms of the Livermore Economic Modeling System

Description: The methodology and the basic pricing algorithms used in the Livermore Economic Modeling System (EMS) are described. The report explains the derivations of the EMS equations in detail; however, it could also serve as a general introduction to the modeling system. A brief but comprehensive explanation of what EMS is and does, and how it does it is presented. The second part examines the basic pricing algorithms currently implemented in EMS. Each algorithm's function is analyzed and a detailed de… more

Internal Technical Report, Safety Analysis Report 5 MW(e) Raft River Research and Development Plant

Description: The Raft River Geothermal Site is located in Southern Idaho's Raft River Valley, southwest of Malta, Idaho, in Cassia County. EG and G idaho, Inc., is the DOE's prime contractor for development of the Raft River geothermal field. Contract work has been progressing for several years towards creating a fully integrated utilization of geothermal water. Developmental progress has resulted in the drilling of seven major DOE wells. Four are producing geothermal water from reservoir temperatures measu… more

Open loop pneumatic control of a Lysholm engine or turbine exhaust pressure

Description: A Lysholm engine, or helical screw expander, is currently being evaluated at the University of California, Berkeley for staging with a conventional turbine in geothermal energy conversion. A pneumatic closed loop, proportional-integral control system was implemented to control the Lysholm engine's exhaust pressure for performance testing of the engine at constant inlet/outlet pressure ratios. The control system will also be used to control the exhaust pressure of the conventional turbine during… more

Large-area silicon sheet by EFG. Fourth quarterly report, October 1-December 31, 1980

Description: Extensive characterization of the multiple ribbon Furnace 3A main zone temperature profile has been performed and the information used to improve uniformity of heating. Irregularities in the main zone heater have been associated with growth difficulties at specific cartridge locations, and growth conditions subsequently improved by profiling the main zone heater. This work has resulted in good growth conditions being established in all three cartridge positions. These improvements have allowed … more

Geothermal-retrofit study for the National Orange Show Facilities in San Bernardino, California

Description: The cost and feasibility of retrofitting the National Orange Show Facilities to use geothermal heat instead of natural gas for heating are determined. Because of the limited usage of the smaller facilities the study was limited to the conversion of the six major buildings: Domed, Hobby, Citrus, Auditorium, Restaurant and Commercial. A major problem is that most of the buildings are used on a very limited basis. This drastically reduced the amount of savings that could be used to amortize the re… more

Bomber Options for Replacing B52s

Description: One of the main issues discussed in this report is the replacement of the B-52 bombers, due to the fact that many believe that by 1990, the B-52's vulnerability to improving Soviet air defenses will imperil its effectiveness as a penetrating bomber.

The Crude Oil Windfall Profit Tax Act: Context and Content

Description: Debate over natural gas pricing has included the consideration of a windfall profit tax, with the oil windfall profit tax as a possible guide to what might be levied on natural gas at the wellhead. This report reviews the issues surrounding the enactment of the crude oil windfall profit tax, spells out its provisions, and provides data on the revenues collected and anticipated.
