Design of a water jet drill for development of geothermal resources. Progress report, October 1--November 30, 1977
Progress is reported in the evaluation of the performance of a water jet drill in a stressed rock, particularly in drilling at hole diameters in excess of one inch. Drilling tests are being carried out in a barrier pillar in a layer of coarse, lead-bearing sandstone. Problems encountered in the test drilling are discussed. (JGB)

Cadmium sulfide/copper sulfide heterojunction cell research. Quarterly technical progress report, June 1-September 30, 1979
Off-stoiciometry CdS coatings with resistivities of about 10..cap omega..-cm have been deposited by a cyclic reactive sputtering process where the H/sub 2/S injection is periodically switched on and off. Cells with CdS layer fabricated in this way have yielded efficiencies of about 0.6% with short circuit currents of about 3.5 mA/cm/sup 2/, open circuit voltages of about 0.43V, and fill factors of about 0.40. CdS resistivity control by In doping has been achieved both by diffusion from a pre-deposited In layer and by using an In-doped Cd sputtering target. Resistivities of about 30..cap omega..-cm are achieved in CdS coatings about 5 um thick deposited at 250/sup 0/C over 50 nm thick In layers. A Cd cathode doped with 1 atomic percent In has yielded CdS coatings with resistivities of about 0.1 ..cap omega..-cm at substrate temperatures in the 100 to 300/sup 0/C range. Cells fabricated from the 0.1 ..cap omega..-cm CdS with a 0.5 um undoped layer adjacent to the junction have yielded encouraging diode characteristics with a strong photovoltaic effect and will be used to an optimization study. Cu/sub x/S coatings deposited onto CdS under various conditions have been found to have the same properties as those deposited onto …

Assessment of proposed federal tax credits for residential wood burning equipment
This report summarizes the results of a study of tax incentives for residential wood burning equipment. It presents an overview of the major issues affecting inclusion or exclusion of this equipment in the NEA tax credit program. The report was prepared as a quick response task within a six week period. Because of these time constraints, many simplifying assumptions had to be made in order to provide information in accordance with the decisionmaking schedule. The report is not meant to be considered as an exhaustive analysis of any particular issue area. (TFD)

Circulating pump impeller: Presbyterian Intercommunity Hospital, Klamath Falls, Oregon, geothermal heating system. Failure analysis report
The Presbyterian Intercommunity Hospital located in Klamath Falls, Oregon utilizes geothermal fluid pumped from its own well to provide space heat and domestic hot water. During an inspection of the heating system after a chemical cleaning of the heat exchangers, the circulating pump was dismantled to replace its seals which were found to be leaking. At that time, the impeller was found to contain many cracks. The analysis of those cracks and a scale sample removed from the impeller is presented. (MHR)
