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.

Understanding Affluence through the Lens of Technology: An Ethnographic Study toward Building an Anthropology Practice in Advertising
This thesis describes a pilot study for a new cultural anthropology initiative at Team One, a US-based premium and luxury brand advertising agency. In this study, I explore the role and meaning of technology among a population of affluent individuals in Southern California through diaries and ethnographic interviews conducted in their homes. Using schema theory and design anthropology to inform my theoretical approach, I discuss socioeconomic and cultural factors that shape these participants' notions of affluence and influence their presentation of self through an examination of their technology and proudest possessions. I put forward a theory of conspicuous achievement as a way to describe how the affluent use technology to espouse a merit-based model of affluence. Through this model of affluence, participants strive to align themselves to the virtuous middle-class while ascribing moral value to their consumption practices. Lastly, I provide a typology of meaningful technology artifacts in the affluent home that describes the roles of their most used tech devices and how each type supports conspicuous achievement.

Helical Screw Expander Evaluation Project. Final report
A functional 1-MW geothermal electric power plant that featured a helical screw expander was produced and then tested in Utah in 1978 to 1979 with a demonstrated average performance of approximately 45% machine efficiency over a wide range of test conditions in noncondensing operation on two-phase geothermal fluids. The Project also produced a computer-equipped data system, an instrumentation and control van, and a 1000-kW variable load bank, all integrated into a test array designed for operation at a variety of remote test sites. Additional testing was performed in Mexico in 1980 under a cooperative test program using the same test array, and machine efficiency was measured at 62% maximum with the rotors partially coated with scale, compared with approximately 54% maximum in Utah with uncoated rotors, confirming the importance of scale deposits within the machine on performance. Data are presented for the Utah testing and for the noncondensing phases of the testing in Mexico. Test time logged was 437 hours during the Utah tests and 1101 hours during the Mexico tests.

Energy conservation in citrus processing. Technical progress report, October 1, 1979-March 31, 1980
The Sunkist Citrus Plant in Ontario, California, processes about 6 million pounds of citrus fruit per day to make products which include frozen concentrated juice; chilled, pasteurized, natural strength juice; molasses from peel; dried meal from peel; pectin; citrus oil; and bioflavonoids. The energy intensive operations at the plant include concentration, drying, and refrigeration. The objective of the two-year two-phase project is to identify an economically viable alternative to the existing method of meeting energy requirements. Progress on the technical work of Phase I is reported. The following are summarized: requirements (energy price projection, atmospheric emission requirements, citrus juice quality constraints, economic evaluations); characterization (basic citrus processing operations, energy consumption and fruit processed vs time, identification and measurement of energy uses, energy balance for a typical citrus juice evaporator); and thermodynamic analysis (heat pump model, thermal evaporator, and co-generation model).
