The purpose of this project is to create a comfortable, low-cost heating system for a single-family house, without dependence on non-renewable energy sources. I have attempted to combine a simple solar air-heating collector with the thermal envelop concept (for thermal air circulation) and massive interior stone walls for heat storage. All building materials, with the exception of the solar glazing material and certain other solar components, are inexpensive and locally produced. Examples are: rough-cut hardwood lumber, sandstone (free for the gathering), galvanized roofing for absorberplate, concrete, concrete block, and cellulose insulation. The collector has operated with a relatively high degree of efficiency, though three 0.6 amp duct fans had to be installed in order to increase air circulation. The interior stonework has provided more than adequate heat storage, along with even heat radiation throughout cloudy periods. My main problem has been heat loss around the foundation.

A need for continuous sampling of the dimensions of superconducting cable has lead to the development of a machine for that purpose. This device measures average thickness, width, and keystone angle for a wide variety of cable sizes while under the mechanical loading anticipated in the final coil structure. Linear dimensions can be measured to {plus minus}0.0001 in. and angle to {plus minus}0. 01{degree}. Cable can be measured with and without insulation. Loading is variable up to 25 ksi. This device has applications in epoxy free coil winding where the cable dimensions must be well understood before coil winding in order to predict the size of the finished coil package. As a diagnostic device, it has application in the cable making process to help understand causes for subtle inconsistencies in cable dimensions. A possible quality control application exists. Current cable quality control requires destructive techniques with very small samplings, usually two samples for 5000 ft of cable. We have evaluated device performance by repeated measurements of lengths of SSC cable. 7 figs.

For a check of the yield estimates expected for the new ACOL target station, calculations have been performed for the CERN parameters using the relatively, simple semi-analytical techniques outlined in pbar note 449. These calculations correspond to operation with a 15 cm long, 1 cm radius lithium lens at 750 T/m gradient, and a 6.5 cm tungsten production target. Comparison with the current calculated yield number for the AA with the present target station configuration (10**7 pbars per 10**13 protons, into dp/p = 1.5%) indicates an increase of a factor of 15 using the normal ACOL parameters (dp/p = 6%, a(transverse acceptance) = 240 pi mm-mrad). As explained in the report, the above lens parameters are not optimized, that is, increases in lens gradient and/or radius will result in an increase in yield, providing the corresponding changes in focal distance, beam line matching, etc. are made.

On Jan. 1, 1981 the Soviet Union's Eleventh Five Year Plan (1981-85) began. An analysis of the new plan provides some insights into Soviet priorities and economic prospects for the next half-decade. The following are the plan's main goals: to allocate sufficient investment funds to ensure adequate growth of output in the industry, agriculture, transportation, energy, and other sectors; to raise consumer income sufficiently to provide needed incentives and increase consumer satisfaction; to meet security needs at home and abroad; and to import technology, grain and other goods needed to meet priority domestic goals.

The prevention of sedimentation or siltation in aquatic ecosystems is always a key environmental issue in the development and operation of power plant units. This report describes a field program which will assess the amount of sedimentation in the streams and tributaties of the Geysers-Calistoga Known Geothermal Resource Area (KGRA) due to development-related or other site-specific activities. This sediment plan is one part of a four part venture - the others are water quality, benthic invertebrates and fisheries studies - initiated by the California Energy Commission and involving numerous California organizations. Included in this report are the cost breakdowns for each phase, maps and rationale of the sampling sites, the methodology for the laboratory sample processing, and examples of the type of graphic and tabular output expected.

More than thirty-seven design concepts have been proposed for terrestrial ICF power plants. The design space is large because of the many allowable driver and reaction chamber combinations. These design studies have illustrated advantages of ICF power plants over other sources in lower impact on the environment, high safety, and almost no dependence on consumables like fuel. The fact that, once built, a 1000 MW/sub e/ ICF power plant would require only 240 kg of deuterium and from 770 to 9260 kg of lithium to run for five years (at 70% capacity factor) makes it potentially attractive for space power also. However, the designs proposed to date have emphasized features that would make the plant attractive for terrestrial applications, where economics, efficiency, and environmental considerations dominate. The resulting plants are large and contain many very heavy components that would not be at attractive for space applications. In this paper, we evaluate alternative ICF driver and reactor technologies using space application criteria and also discuss how some of those technologies can be altered to produce smaller, lighter fusion power sources for space.

316L stainless steel is a candidate material for construction of equipment that will be exposed to tritium. Proper design of the equipment will require an understanding of how tritium and its decay product helium affect mechanical properties. This memorandum describes results of rapid heating tensile testing of hydrogen-charged specimens of high-energy-rate-forged (HERF) 316L stainless steel. These results provide a data base for comparison with uncharged and tritium-charged-and-aged specimens to distinguish the effects of hydrogen and helium. Details of the experimental equipment and procedures and results for uncharged specimens were reported previously. 3 refs., 10 figs.

The TNX Area post-Cretaceous hydrogeological section consists of an unconfined aquifer in recent to Pliestocene age sediments and a confined aquifer in tertiary aged sediments. The unconfined aquifer is a local water bearing reservoir and will not be correlated to a specific stratigraphic unit at this time. Depth to the water table ranges from 25 feet at the New TNX Seepage Basin to 50 feet at the Old TNX Seepage Basin. The unconfined aquifer is 45--50 feet thick and outcrops in the swamp to the west of TNX. The hydraulic gradient in the unconfined aquifer decreases westerly across the TNX Area from 0.05 to 0.01. The unconfined aquifer is separated from the underlying confined aquifer by a sandy slit aquitard (A1) which is approximately 5--10 feet thick. Researchers reported an increase in hydraulic head across this unit of approximately 8 feet which results in an upward gradient between the unconfined and confined aquifer. The confined Tertiary aquifer (C1) at TNX is 25--30 feet thick and can generally be found 60 to 90 feet below the surface. The C1 aquifer is part of the aquifer commonly referred to as the Congaree'' which occurs in the Congaree Formation. The C1 aquifer lies …

The design and implementation of the downhole portion of a measuring system for gamma rays is presented. Included are three alternative designs for radiation-resistant collimating and condensing lenses, sample cells, turning mirrors, and fiber-optic termination techniques. Also discussed are mechanical mounts and positioners, shielding, alignment, test methods, and field installation. Some general design suggestions for optical systems in adverse environments are also presented.

This report consists of three major sections which are: progress made on the development of a generic plant growth model, progress made on the holistic ecosystem model, and a summary outlining future directions of our modeling efforts. The major accomplishments of the plant growth modeling have been the identification and implementation of components for the photosynthesis module, development of a plant canopy module, and further refinement of the various modules that make up the basic structure for a generic plant growth mode. Research examined several implementations of a leaf-based, CO{sub 2} responsive, photosynthesis model that incorporates information at the enzyme-kinetics level. Also presented, are several models of forest canopies, transpiration, and photosynthesis.

Wave heating of ELMO BUMPY TORUS-SCALE (EBT-S) in the ion-cyclotron range of frequencies will be strongly influenced by the geometry of the plasma. In particular, the short finite length of the mirror sections means that the electron bounce frequency is of comparable magnitude to the ion-cyclotron frequency. Consequently, the bouncing motion of trapped particles impacts the electron absorption of wave energy. Furthermore, the varying magnetic field strength along magnetic field lines influences the ion-cyclotron absorption of waves because the ion-cyclotron resonance conditions are satisfied only at discrete points along the field lines. Expressions are given for trapped and passing electron absorption as well as ion-cyclotron absorption. A numerical example is also discussed.

The control system for the Nova laser must operate reliably in a harsh pulse power environment and satisfy requirements of technical functionality, flexibility, maintainability and operability. It is composed of four fundamental subsystems: Power Conditioning, Alignment, Laser Diagnostics, and Target Diagnostics, together with a fifth, unifying subsystem called Central Controls. The system architecture utilizes a collection of distributed microcomputers, minicomputers, and components interconnected through high speed fiber optic communications systems. The design objectives, development strategy and architecture of the overall control system and each of its four fundamental subsystems are discussed. Specific hardware and software developments in several areas are also covered.
