Fixed tilt solar collector employing reversible vee-trough reflectors and vacuum tube receivers for solar heating and cooling systems. Final report. JPL Publication 77-78
The objective of the Vee-Trough/Vacuum Tube Collector (VTVTC) Project was to prove the usefulness of vee-trough concentrators in improving the efficiency and reducing the cost of collectors assembled from evacuated tube receivers. The VTVTC was analyzed rigorously and various mathematical models were developed to calculate the optical performance of the vee-trough concentrator and the thermal performance of the evacuated tube receiver. A test bed was constructed to verify the mathematical analyses and compare reflectors made out of glass, Alzak and aluminized FEP Teflon. Tests were run at temperatures ranging from 95 to 180/sup 0/C during the months of April, May, June, July and August 1977. Vee-trough collector efficiencies of 35 to 40% were observed at an operating temperature of about 175/sup 0/C. Test results compared well with the calculated values. Test data covering a complete day are presented for selected dates throughout the test season. Predicted daily useful heat collection and efficiency values are presented for a year's duration at operation temperatures ranging from 65 to 230/sup 0/C. Estimated collector costs and resulting thermal energy costs are presented. Analytical and experimental results are discussed along with a complete economic evaulation. Recommendations for the continuation of the project are presented.

Steady-State Thermomechanical Finite Element Analysis of Elastoviscoplastic Metal Forming Processes
Extrusion and rolling processes exhibiting large amounts of plastic flow are analyzed using a finite element technique that is based on a modified creeping viscous flow approximation. The technique, called the initial stress-rate method, iteratively corrects creeping viscous flow solutions to generate results that include elastic response. The momentum equations have been coupled with the energy equation to provide the capability to predict thermomechanical response during forming operations.

Atlantic Coastal Plain. Geothermal energy and the eastern US: a scenario for geothermal energy development
A brief narrative outline is presented of a scenario for the development of the Atlantic Coastal Plain hydrothermal resources for geothermal space heating and cooling. Listed below are the basic assumptions made in the construction of this scenario. Since this scenario is to serve as a planning document, the steps involved in geothermal development are listed and time-phased. The most critical steps in this process are indicated. This scenario summarizes geothermal development in the entire Atlantic Coastal Plain. Separate, more detailed scenarios for each specific resource area are planned as precursors to possible implementation planning.

Nomenclature of Precambrian Rocks in Colorado
Abstract: "The Precambrian rocks of Colorado consist of a metaphoric complex more than 1,700 million years in age, three groups of igneous rocks about 1,700, 1,400, and 1,000 million years in age, here designated informal age groups, and two areally restricted units of sedimentary rocks, one between 1,400 and 1,700 million years in age and one between 950 and 1,400 million years. A systematic nomenclature for many of the rocks does not exist, but the present state of knowledge will permit establishment of a comprehensive nomenclature. Numerous formal names that have been applied to elements of the Precambrian assemblage are appraised and classified in a table, and eight names are abandoned."

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas
The Nevada Operations Office of the Energy Research and Development Administration (ERDA) has contracted with Petroleum Technology Corporation (PTC) to perform a gas stimulation program by chemical explosive fracturing (CEF) in the Canyon sands of the Val Verde - Kerr Basin of Sutton County, Texas. This lenticular tight sand deposit, underlying much of southwestern Texas, contains large volumes of natural gas. To date this formation has yielded only marginal amounts of gas because of its low porosity and permeability. The semi-arid environment of the Aldwell/Sawyer field is characterized by dry arroyos and xeric vegetation. Population is sparse and sheep ranching is the primary occupation. Because of the existence of previously drilled oil and gas wells, road and pipeline construction will be minimal. Impacts from this two well project are expected to be minimal and be confined to temporary surface disruption and increased erosion at the well site.
