Establish Feasibility for Providing Passive Cooling With Solar Updraft and Evaporative Downdraft Chimneys

Description: Natural draft towers can be used for cooling and ventilating structures. From an operational perspective, the downdraft evaporatively cooled tower is preferred for a dry climate. Solar chimneys, when used alone, tend to require an excessively large solar collector area when appreciable quantities of air must be moved. When used in combination with a downdraft tower, the roof and attic of buildings may assist the solar chimney and their use becomes more attractive. Both a frame building and a gr… more

Expectations for a second US Hot Dry Rock Site

Description: The worlds first hot dry rock (HDR) reservoir was created at Fenton Hill, NM in the late 1970's. Today, Fenton Hill is the site of the largest, deepest, and hottest HDR reservoir. Over the past two decades, HDR systems have also been developed in a number of other countries. However, HDR reservoirs to date have always been created as part of research and development programs aimed at understanding the fundamentals of HDR technology. The time has come to begin planning the construction of a comm… more

Magnitude and value of electric vehicle emissions reductions for six driving cycles in four US cities with varying air quality problems

Description: The emissions of logically competing mid-1990 gasoline vehicles (GVs) and electric vehicles (EVs) are estimated as if the vehicles were driven in the same pattern of driving. Six different driving cycles are evaluated, ranging in speed from 7 to 49 miles per hour (mph). These steps are repeated using specifics of fuel composition, electric power mix, and environmental conditions applicable to Chicago, Denver, Los Angeles, and New York in the month of July. The year 2000 emissions differences fo… more

Experimental and theoretical investigation of the production of HCl and some metal chlorides in magmatic/hydrothermal systems

Description: In the calculations we have assumed that all apatites are magmatic. The presence of chlorite and altered plagioclase within the granite and quartz-monzodiorite suggests that alteration may play a role in leading to erroneous estimates of initial melt Cl and F for 2 reasons: (1) the apatites may in fact not be magmatic in origin, but are hydrothermal, and (2) the halogen signature of magmatic apatite may be changed due to subsolidus exchange with a hydrothermal fluid. We are currently endeavorin… more

Fuel cells for extraterrestrial and terrestrial applications

Description: The fuel cell is a nineteenth century invention and a twentieth century technology development. Due to the high power and energy density, high efficiency, reliability, and production of pure water, hydrogen-oxygen fuel cell systems have no competition as auxiliary power sources for space vehicles. The alkaline fuel cell system is a well developed and proven technology for this application. The solid polymer electrolyte system may be its future competitor. The energy crisis of 1973 stimulated re… more

Search for UHE emission from Cygnus X-3

Description: Data from the CYGNUS experiment has been searched for evidence of ultra high energy (UHE) emission from Cygnus X-3. An upper limit to continuous flux from the source is given. In addition, we find no evidence for episodic emission from Cygnus X-3 on any time scale from 3.3 minutes to 4 years. The results of searches for periodic emission from Cygnus X-3 will be presented at the conference.

Identification of environmentally derived cesium-137 burdens in a worker population

Description: During 1990, whole body measurements of a number of workers with little probability of onsite occupational exposure showed positive evidence of [sup 137]Cs. Further investigation revealed that many of these workers supplemented their diet with a significant portion of wild game, mainly deer and elk. To validate the assumption of an environmental source, donated samples of venison and other game were analyzed by gamma spectroscopy. Results ranged from less than 0.1 to almost 100 Bq kg[sup [minus… more

Upper ocean model of dissolved atmospheric gases

Description: The goal of this project is to estimate the rate of biological oxygen production at Hawaiian Ocean Time-series station ALOHA in the central North Pacific ocean. Our approach is to use an upper ocean model together with measurements to interpret an annual cycle of temperature, salinity, dissolved oxygen, argon, nitrogen, and the stable isotope ratio of oxygen at station ALOHA. This project represents the first upper ocean geochemical study in which model predictions are verifiable by independent… more
