Magma fuel cell. [For energy extraction from magma or for electrochemical protection of heat exchangers in magma]

Description: A high temperature, solid-electrolyte fuel cell is described which uses molten rock having oxidizable constituents as a fuel. The principles of this magma fuel cell have been successfully demonstrated and power densities of 88 W/m/sup 2/ have been achieved. If power densities can be substantially increased, the magma fuel cell may find numerous applications in magma tap projects to increase the efficiency of energy extraction from magma sources or may provide the energy necessary for the electr… more

Inspection of aluminum components from freeze desalting facility at Wrightsville Beach, NC

Description: An inspection was made of a freeze-type desalting pilot plant that has operated for approximately four years. The purpose of this inspection was to document the seawater service experience of the various aluminum alloys present in the plant. The components inspected include two tube-type heat exchangers, one plate-type heat exchanger, and the freezing compartment. Photographs are used to illustrate the corrosion behavior of these components.

Potential effects of hydrogen sulfide gas from geothermal energy conversion on two plant species native to northern New Mexico

Description: Dry weight of topgrowth, water content of topgrowth, leaf nitrogen content, and leaf chlorophyll content were measured in well-watered, field-exposed little bluestem (Schizachyrium scoparium Nash.) and mountain brome (Bromus marginatus Nees.) plants fumigated with various mean levels of H/sub 2/S ranging from 0.05 to 3.58 ppM. The youngest fully expanded leaves were sampled for chlorophyll content after 60, 80, 100, and 140 and 60, 80, 120, and 140 h total of fumigation for little bluestem and … more

Plasmadynamics and ionization kinetics of thermionic energy conversion

Description: To reduce the plasma arc-drop, thermionic energy conversion is studied with both analytical and numerical tools. Simplifications are made in both the plasmadynamic and ionization-recombination theories. These are applied to a scheme proposed presently using laser irradiation to enhance the ionization kinetics of the thermionic plasma and thereby reduce the arc-drop. It is also predicted that it is possible to generate the required laser light from a thermionic-type cesium plasma. The analysis t… more

Electrokinetic Power Generation from Liquid Water Microjets

Description: Although electrokinetic effects are not new, only recently have they been investigated for possible use in energy conversion devices. We have recently reported the electrokinetic generation of molecular hydrogen from rapidly flowing liquid water microjets [Duffin et al. JPCC 2007, 111, 12031]. Here, we describe the use of liquid water microjets for direct conversion of electrokinetic energy to electrical power. Previous studies of electrokinetic power production have reported low efficiencies (… more

Longitudinal Density Modulation and Energy Conversion in Intense Beams

Description: Density modulation of charged particle beams may occur as a consequence of deliberate action, or may occur inadvertently because of imperfections in the particle source or acceleration method. In the case of intense beams, where space charge and external focusing govern the beam dynamics, density modulation may under some circumstances be converted to velocity modulation, with a corresponding conversion of potential energy to kinetic energy. Whether this will occur depends on the properties of … more

Application of Gamma code coupled with turbomachinery models for high temperature gas-cooled reactors

Description: The very high-temperature gas-cooled reactor (VHTR) is envisioned as a single- or dual-purpose reactor for electricity and hydrogen generation. The concept has average coolant temperatures above 9000C and operational fuel temperatures above 12500C. The concept provides the potential for increased energy conversion efficiency and for high-temperature process heat application in addition to power generation. While all the High Temperature Gas Cooled Reactor (HTGR) concepts have sufficiently high … more

Applications of laser diagnostics in energy conservation research

Description: During the past decade, intensive research and development has demonstrated the feasibility, checked the accuracy, and extended the sensitivity of laser diagnostics for combustion systems. Combinations of diagnostics can now provide in-situ, time-, and space-resolved measurements of temperature, velocity, and species concentration. Although these tools are powerful, they also can be exceedingly difficult to use, and their application remains largely in the hands of specialized instrument develo… more

Dynamic Theory: some shock wave and energy implications

Description: The Dynamic Theory, a unifying five-dimensional theory of space, time, and matter, is examined. The theory predicts an observed discrepancy between shock wave viscosity measurements at low and high pressures in aluminum, a limiting mass-to-energy conversion rate consistent with the available data, and reduced pressures in electromagneticaly contained controlled-fusion plasmas.
