Application of microfabrication technology to thermionic energy conversion. Final report, 1 April 1979-31 March 1981
The first-year effort emphasized study of the kind of microstructures that could improve the performance of thermionic converters. Two ideas considered to have a fair chance of success emerged from this study: (1) use of a very closely spaced diode to eliminate the space-charge limitation of electron flow from emitter to collector, cesium vapor being used to control the work function of the emitter; and (2) use of field emission electrons, injected into a relatively large diode gap from microcathodes built into the collector, to produce ions to neutralize the space charge. The gas in the diode gap would be a mixture of cesium (to control the emitter work function) and xenon to optimize the ionization. A number of schemes were attempted to build closely spaced diodes with spacing in the 1 to 5 ..mu..m range, which overcame the problems of lateral differential expansion, surface irregularities on the electrodes, and heat loss down the pillars holding the gap spacing. Theoretical studies on using field emitter electrons to produce the space charge neutralizing ions showed that this approach was feasible. However, the program was terminated before any experimental work could be initiated in this area.

Preliminary assessment of Fort Hood solar cogeneration plant performance
An analysis has been performed to enable a preliminary assessment of the performance that can be expected of a solar thermal cogeneration system designed to serve a selected group of buildings at Fort Hood, Texas. A central receiver system utilizing a molten salts mixture as the receiver coolant, heat transfer fluid, and storage medium is assumed. The system is to supply a large share of the space heating, air conditioning, domestic hot water, and electricity needs of a 20-building Troop Housing Complex. Principal energy loads are graphed and tabulated, and the principal electric parasitic loads are tabulated and the methodology by which they are estimated is reviewed. The plant model and the performance calculations are discussed. Annual energy displacement results are given. (LEW)

Conceptual design of a solar cogeneration facility at Pioneer Mill Co. , Ltd
Results are reported of a conceptual design study of the retrofit of a solar central receiver system to an existing cogeneration facility at a Hawaii raw sugar factory. Background information on the site, the existing facility, and the project organization is given. Then the results are presented o the work to select the site specific configuration, including the working fluid, receiver concept, heliostat field site, and the determination of the solar facility size and of the role of thermal storage. The system selected would use water-steam as its working fluid in a twin-cavity receiver collecting sunlight from 41,420 m/sup 2/ of heliostat mirrors. The lates version of the system specification is appended, as are descriptions of work to measure site insolation and a site insolation mathematical model and interface data for the local utility.

Static reactive power compensators for high-voltage power systems. Final report
A study conducted to summarize the role of static reactive power compensators for high voltage power system applications is described. This information should be useful to the utility system planning engineer in applying static var systems (SVS) to high voltage as (HVAC) systems. The static var system is defined as a form of reactive power compensator. The general need for reactive power compensation in HVAC systems is discussed, and the static var system is compared to other devices utilized to provide reactive power compensation. Examples are presented of applying SVS for specific functions, such as the prevention of voltage collapse. The operating principles of commercially available SVS's are discussed in detail. The perormance and active power loss characteristics of SVS types are compared.

Power recovery system for coal-liquefaction process. [Patent application]
Method and apparatus for minimizing energy required to inject reactant such as coal-oil slurry into a reaction vessel, using high pressure effluent from the latter to displace the reactant from a containment vessel into the reaction vessel with assistance of low pressure pump. Effluent is degassed in the containment vessel, and a heel of the degassed effluent is maintained between incoming effluent and reactant in the containment vessel.

Equipment for drilling miniature holes
Miniature holes are produced on 16 different types of mechanical drilling equipment. Each equipment type has significant advantages for a specific type of part. The basic capabilities vary greatly between equipment types. Some produce very precise holes and others produce very high volumes of commercial tolerance holes. At the present time machines are available for mechanicaly drilling up to 100,000 miniature holes per hour. Lasers currently are drilling as many as 15,000,000 ultra-miniature holes per hour.

Air separation by the Moltox process
The report describes results of a development program on a new and energy saving process for air separation. The Moltox process involves reversibly reacting oxygen in air with a recirculating salt solution, such that oxygen is extracted without depressurizing the remaining nitrogen. Energy savings of approximately 50% are indicated for this process compared to conventional cryogenic air separation. The development program consisted of design, construction, and operation of a 6 liter/minute pilot plant; optimization of the process flowsheet through computer modelling; investigation of engineering aspects of the process including corrosion, safety, and NO/sub x/ generation; and an economic comparison to conventional cryogenic practice. All objectives were satisfactorily achieved except for continuous operation of the pilot plant, and the modifications necessary to achieve that have been identified. Economically the Moltox process shows a substantial advantage over large scale cryogenic plants which are powered by fuel vice electricity.
