The contract objective is to complete the design and development actions that upgrade the 40-kW fuel cell power plant to a configuration suitable for on-site demonstration testing. The modifications will improve operating capability, durability and maintenance interval and lead to reduced production costs. Equipment to recover and use the by-product heat of electric generation will be available on the power plant for field verification of on-site heat recovery. The 40-kW power plant will be compatible with the power characteristics required for conventional heat pumps and conventional 60 Hz, 120/208 volts electrically operated equipment. Progress is reported. (WHK)

three separate technologies were discussed but, because of the background of the discussants, the greater part of the discussion focused on geopressure aquifers. In general, there was considerable agreement with regard to the level and types of technological and economic uncertainty, the institutional barriers, and the role that the federal government should take in enhancing commercialization. The resource is considered to be vast and if the market were allowed to operate freely the demand for the gas would be considerable. It was estimated that in a free market an annual demand of up to 30 trillion cubic feet could be expected in the near future. The industry representatives think that the market demand would be greater than estimates compiled by the government because those demand estimates were influenced downward by assumptions of relatively constrained supply. It was agreed that the economic incentives available to industrry, given the current regulation of price, are not sufficient to induce significant risk captial into well drilling in search of geopressurized gas. A common industry position is that the government needs to provide front-end funds to at least assist in well drillings, or for additional research within existing wells. The goal of this research would …

To predict the dimensions and characteristics of impact- and explosion-induced craters, one must know the equation of state of the rocks in which the crater is formed. Recent experimental data shed light upon inelastic processes that influence the stress/strain behavior of rocks. We examine these data with a view to developing models that could be used in predicting cratering phenomena. New data is presented on the volume behavior of two dissimilar rocks subjected to tensile stresses.

It is shown that substantial amounts of untransformed austenite may be obtained in low alloy steels by a combination of alloy modification (addition of silicon) and heat treatment. In silicon modified AISI 4330 steel, the amount of untransformed austenite is varied by utilizing isothermal treatments both above and below the M/sub s/. The stability of the untransformed austenite is found to be dependent on the amount of silicon and also on the tempering temperature. A magnetic saturation technique was utilized to monitor the transformation of the austenite under uniaxial tensile loading. An improvement in the plane strain fracture toughness (K/sub Ic/) was observed when the retained austenite transformed with respect to strain. This improvement was optimized with particular combinations of stability and volume fractions of retained austenite. The addition of silicon resulted in an increase of both the strength and the fracture toughness (K/sub Ic/) of the quenched and tempered AISI 4330 steel. Yield strengths in the range of 200-220 ksi and K/sub Ic/ values as high as 107 ksi..sqrt..in were obtained. The microstructure was characterized using both optical and electron microscopy and is correlated with the mechanical properties.

Early in 1976, JPL conducted a survey of California utilities to ascertain their views on the probable rate of geothermal development in the State of California in the immediate future (Reference 1). At the time the survey was conducted, the only firm utility plans for geothermal generating capacity were for the Geysers dry steam field in Northern California; experimental work on utilization of the hot water fields of the Imperial Valley was in its early stages. All of the utilities contacted indicated a willingness to consider geothermal energy as an alternative to gas- and oil-fired plants, but most emphasized that their prime reliance would be on nuclear power to meet future demand growth. Over the ten-year period 1976-1986, they foresaw a maximum of 2500 MW of geothermal capacity coming on-line, and, of this, 2150 NW was at The Geysers (see Figure 1). Since that survey was conducted, a number of new factors have entered the utility planning picture. Most significant has been the hardening of attitudes in the State against the installation of nuclear plants, and the emphasis on seeking alternative energy sources. Two major nuclear projects, Sundesert and San Joaquin, have been abandoned, and the passage of stiff regulatory …

The requirements a heavy ion accelerator must meet in order to initiate practical thermonuclear microexplosions are summarized. Particular emphasis is given to the question of maximum allowable ion energy.

Absolute rate coefficients for the reaction of O-atoms and H-atoms with formaldehyde were determined over the temperature range of 250 o 500 K. Rate parameters were determined from plots of log k vs. 1/T which were found to follow the linear Arrhenius behavior. These results are compared with those of previous studies and further discussed in terms of a formaldehyde conversion mechanism.

Experimental work in the area of the ambient-temperature, steady-state behavior of the lithium electrode was completed. The following conclusions were drawn: 100 percent coulombic efficiency may be approached over a wide range of concentrations, flow conditions, and current densities; coulombic efficiency is approximately equal to I/sub e//I/sub l/, and I/sub e/ is the current in the external circuit, and I/sub l/ is the diffusion-limited current. Li electrode resistivities of (0.4 to 1.0) x 10/sup -4/ ..cap omega..-m/sup 2/ were obtained, and thus the plane-parallel configuration is suitable for batteries of the lithium-water type. Work on the characterization of Li/I/sub 2/ and Li/Br/sub 2/ analog batteries was begun. (RWR)

Polymer coated spherical targets have been irradiated by the Shiva laser system in an effort to compress the contained 10 mg/cc DT fuel to super liquid densities. Glass microspheres of 140 ..mu..m ID and 5 ..mu..m wall thickness with polymer coatings 15 ..mu..m to 100 ..mu..m thick have been irradiated with laser pulses of 4 kilojoules in 200 psec FWHM. Target performance was diagnosed with neutron yield measurements, radiochemistry, Argon line imaging, and x-ray imaging techniques. Ball in plate targets achieved greater implosion symmetry than free-standing ball targets. With yields of 10/sup 7/ to 10/sup 8/ neutrons, targets reached DT fuel compressions of several times liquid density.

Research and development of a solar desiccant dehumidifier featuring a rotary bed of granular silica gel and a rotary regenerator for air conditioning is described. The results of the system optimization studies are presented. The studies involved an extensive investigation of the energy saving potential and economic viability of the solar desiccant dehumidifier in different locations in the United States. Conventional electric vapor compression, and solar absorption and Rankine systems also were investigated for comparison. In general, it was found that the solar desiccant equipment, either by itself or in a hybrid system with an electric vapor compression air conditioner, is economically viable for all three locations considered. Substantial energy savings can be effected as well. Seal tests done at AiResearch to develop practical dynamic air seals are described. Leakage and friction tests were performed on a variety of material combinations and configurations. Dacron felt and silicone rubber were found to give an acceptable combination of leakage, friction, and cost characteristics. As part of the commercialization studies for the desiccant equipment, a questionnaire was sent to residential air conditioning equipment distributors. The results of the questionnaire are presented. The specifications and drawings for the 1.5-ton prototype are included. (WHK)
