Geothermal development plan: Cochise/Santa Cruz Counties

The Cochise/Santa Cruz Counties Area Development Plan evaluated the regional market potential for utilizing geothermal energy. The study identified three potential geothermal resource areas with potential for resource temperatures less than 90/sup 0/C (194/sup 0/F). Geothermal resources are found to occur near the towns of Willcox, San Simon, and Bowier. Population growth rates are expected to average three percent per year over the next 30 years in Willcox; Bowie and San Simon are expected to grow much slower. Regional employment is based on agriculture and copper mining, though future growth in trade, services and international trade is expected. A regional energy-use analysis is also included. Urban use, copper mining and agriculture are the principal water users in the region and substantial reductions in water use are anticipated in the future. The development plan also contains a section identifying potential geothermal energy users in the region. Geothermal energy utilization projections suggest that by the year 2000, geothermal energy might economically provide the energy equivalent of 3,250,000 barrels of oil per year to the industrial sector. In addition, geothermal energy utilization might help stimulate an agricultural and livestock processing industry

Transport Properties of Solitons

We calculate in this article the transport coefficients which characterize the dynamics of solitons in quantum field theory using the methods of dissipative quantum systems. We show how the damping and diffusion coefficients of soliton-like excitations can be calculated using the integral functional formalism. The model obtained in this article has new features which cannot be obtained in the standard models of dissipation in quantum mechanics.Comment: 16 Pages, RevTeX, Preprint UIU

A Biased Review of Sociophysics

Various aspects of recent sociophysics research are shortly reviewed: Schelling model as an example for lack of interdisciplinary cooperation, opinion dynamics, combat, and citation statistics as an example for strong interdisciplinarity.Comment: 16 pages for J. Stat. Phys. including 2 figures and numerous reference

Geothermal development plan: Yuma County

Alternative sources of energy will have to be developed as the availability of traditional energy resources continues to diminish. Arizona is supplied with geothermal reserves which could potentially supplement the existing energy supplies. Consequently, planning efforts have concentrated on estimating the potential of geothermal energy utilization in Arizona and in providing information necessary for its prospective commercialization. Geothermal commercialization plans were prepared for seven distinct intrastate subdivisions. The geothermal resource prospect and the potential geothermal uses for each area are discussed in separate Area Development Plans (ADPs). The major objective of the ADP is to provide information for the prospective development and commercialization of geothermal energy in the specified area. Attempts are made to match the available geothermal resources to potential residential, commercial, industrial and agricultural users. 22 pages.Documents in the AZGS Documents Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.

Temperature-depth profiles, well location information, and tabulated temperatures for Arizona wells measured between May 1979 and March 1982

The Department of Energy funded reconnaissance geothermal exploration in the State of Arizona between May, 1979 and August, 1982. During that time geologists of the Arizona Bureau of Geology and Mineral Technology were able to measure temperatures in over 100 domestic and irrigation wells and mineral test holes. Thirteen holes were drilled solely for the purpose of obtaining gradient or heat flow information. The temperature measurements were made using a portable temperature logging system that consists of a thermistor mounted on the end of lightweight cable, which is carried on a light aluminum reel. The thermistor resistance is measured by a digital meter supplied by rechargeable batteries. Resistance values were converted into temperature for each reading by using tables constructed from thermistor temperature calibration.Documents in the AZGS Document Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.

Irrigation pumping using geothermal energy

The potential of using geothermal energy in an isobutane binary system to drive directly a cluster of irrigation pumps was evaluated. This three well geothermal system, based at 150{sup 0}C (302{sup 0}F) resource at 2000 m (6560 ft), would cost an estimated $7,800,000 in capital investment to provide 6000 gpm of irrigation water from 12 water wells. It would serve approximately 4.5 square miles of irrigated agricultural land, with the delivered water costing$106.76 per acre-foot. This compares with an estimated cost of $60.78 per acre-foot for a conventional irrigation system driven by natural gas at the current price (1980 dollars) of$2.72/mm Btu. It is obvious that if natural gas prices continue to rise, or if geothermal resources can be found at depths less than 2000 meters, then the geothermal irrigation pumping system would be attractive economically. The importance of water to the economy and growth of Arizona was summarized. Total water consumption in Arizona is about 7,600,000 acre-feet annually of which about 87% is used for agriculture. Total supply from the Colorado River and water runoff is only 2,600,000 acre-feet per year, resulting in a net potable groundwater depletion of about 4,000,000 acre-feet per year assuming a recharge rate of about 1,000,000 acre-feet per year
