Natural Resource Pricing And Economic Development, Vaman Rao
Natural Resource Pricing And Economic Development, Vaman Rao
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In a competitive equilibrium the price of a natural resource will be increasing at a rate equal to the social time preference rate, but in a monopoly market, the price will be increasing at less than social time preference rate. If the producer countries utilise their monopoly of production and sale of a natural resource for the purpose of developing their economies, the price of the natural resource will be growing at the rate at which the producer countries' economies are growing, whether or not the sales proceeds are used to finance their investment programmes, fully or partly.

A preliminary engineering, geological, and hydrological environmental assessment of a proposed 250 MMSCFD dry ash Lurgi coal gasification facility is discussed.
The facility's emission spectrum is examined on the basis of the proposed design and empirical data. This system utilizes approximately 13 million tons of lignite and 17,000 acre feet of water per year and consumes 6500 tons of oxygen per day. The results of the study indicate that the major gaseous effluent is CO2, that the federal limits on SO2 effluent may be met, and that the atmospheric degradation criterion will be the most difficult one …
Solar Assisted Power Systems, A. G. Potter
Solar Assisted Power Systems, A. G. Potter
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Except for hydroelectric power, solar electric generation has not been widely used in the past to assist power system generation because of its relatively high cost. This situation has now started to change with the advent of the energy crisis as exemplified by decreasing natural gas supplies and increasing fossil fuel prices. One possible response to this situation which appears to have a relatively good chance for economic success is the utilization of wind and solar thermal energy for space and water heating loads served by natural gas or electric power. Unfortunately, a large portion of the energy collected in …
Wind Energy Concentrators, John L. Loth
Wind Energy Concentrators, John L. Loth
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper presents two alternatives to the shrouded propeller wind energy concentrator. Their operation is based on generating a low pressure area, with high local wind velocity, around the windmill rotor.
The two types of wind energy concentrators considered are: (1) the "obstruction type" concentrator where a vertical cylinder or vertical flat surface is used to produce high local velocities around two counter-rotating vertical axis rotors, and (2) the "vortex type" concentrator where a horizontal vortex is generated by a vertical high lift wing of finite span. The high local wind kinetic energy inside the vortex is harnessed by a …

Energy From Agriculture, E. C. Clausen, D. L. Million, Efton Park, J. L. Gaddy
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
During the past few years, the demand for energy and petrochemicals has grown at a pace so rapid that our reserves of fossil fuels, once considered inexhaustible, are now being quickly depleted. To help lessen this impending problem, alternative sources of energy must be rapidly developed.
Of the many new sources of energy being studied, solar energy, undisputedly, is the most inexhaustible. Energy from the sun, incident upon the earth's surface, exceeds by nearly three orders of magnitude the total energy consumption today. Furthermore, it is not subject to nationalistic boundaries and its use would be compatible with our environmental …

Planned Reduction In Electrical Energy Use In Nashville - Davidson County, Tennessee: A Preliminary Assessment, Barry D. Lichter, William F. Flanagan, Robert S. Goodrich, James K. Sebenius, C. Paul Beach
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
An assessment was carried out of the impacts of the various alternative strategies designed to reduce the rate of electrical energy use in the Nashville-Davidson County area, in the light of a potential crisis in supply. Seven strategies were identified among the major categories of voluntary reduction, price regulation, and mandatory reduction. Thirty-three sub-sectors were identified among residential, commercial and industrial users, and the consequences of imposing the strategies were assessed using a cross-impact matrix. The value of the methodology as an aid to public policy formulation lies in its possible extension to allow direct participation of various affected publics.

Energy Conservation Program At Ralston Purina, George A. Bossman
Energy Conservation Program At Ralston Purina, George A. Bossman
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
While the food industry as a whole uses only about 5 per cent of total manufacturing energy, we at Ralston Purina Company recognize our dependence upon energy and the importance of a strong energy management program. Last year, as part of this program, we established and implemented an energy conservation program designed to identify opportunities for conservation.
The major thrust of this program has been directed at manufacturing facilities where usages can be traced, wastes detected, and appropriate action taken. These are separate from a general overall corporate effort to make employees more energy conscious in every phase of their …

Osmo - Power. Osmotic Work; Energy Production From Osmosis Of Fresh Water/Sea-Water Systems, H. H. G. Jellinek
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
It is imperative that new and ecologically acceptable energy sources are made available. Solar energy is a source which seems to be inexhaustible and free of pollution hazards. One vast source, which can be considered to be a solar energy source consists of the system fresh water/sea water. Fresh water is continually removed by the hydrological cycle where water evaporates from the ocean due to solar radiation and is eventually precipitated again in the form of fresh water feeding various rivers. Fresh water and ocean (salt) water mix when rivers flow into the oceans. The different chemical potentials are equalized …

Alternative Approaches To Energy Modeling, Alan S. Cohen, Kenneth W. Costello
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The effects of government and private sector energy policies are varied and interrelated. Before implementing research and development programs, new technologies, environmental and price regulations, import quotas, and other energy-related policies, the consequences of these programs must be identified and quantified on a regional basis. To evaluate the regional impacts of energy policies, we need to consider production costs, transportation costs, and the location of reserves, as well as the demands for energy and nonenergy goods. Developing techniques for analyzing these factors was the objective of many previous research efforts. The strengths and weaknesses of the resulting models are discussed …
Energy Management In The Food Store, Paul Adams
Energy Management In The Food Store, Paul Adams
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Food store refrigeration is vital to the food distribution system and consumes much of the energy used in a supermarket. The manufacturers of food store display equipment have worked long and hard to develop new ideas in supermarket energy conservation. Hussmann's studies have uncovered a number of facts invaluable to anyone concerned with energy conservation in the supermarket.
The first fact is to realize that supermarkets are different from any other retail stores. They consume more energy each year per sq. ft. of store - or per customer - or per dollar sales than other retail stores and most commercial …
Efficiency In The Use Of Energy Has Been Effected Through Industrial Use Of Subsurface Space, Truman Stauffer Sr.
Efficiency In The Use Of Energy Has Been Effected Through Industrial Use Of Subsurface Space, Truman Stauffer Sr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Our Nation, with its high standard of living made possible by industrialization, draws heavily on energy producing natural resources. Self reliance mandates the use of every measure of conservation in order to extend the yet finite supply of energy to meet our national needs. Efficiency in the use of energy has been and can increasingly be effected through industrial use of subsurface space. The use of mined rooms for industry and warehousing utilizes the natural stable underground temperature and the low coefficient of heat transfer existing naturally in the lithosperic materials of the subsurface environment. The small amount of energy …

Oil Shale R & D -- A Bureau Of Mines Program, Steve Utter
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy is one of our basic natural resources. Oil constitutes an important part of this resource but domestic production is dropping while imports are rising. Today, oil represents about one-half of the total energy consumed in this country, and demand is expected to grow at the rate of about 2 percent per year during the next 10 years. Increased reliance on imports can be reduced by synthetic fuels produced from the oil shale deposits of the Green River Formation in Colorado, Utah, and Wyoming. These deposits are so enormous (600 billion barrels in high- grade shale alone), that any limitations …

The performance of the two laboratory machines and the potential …
Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley
Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A methodology for evaluating the total or life-cycle cost of an on-site solar energy system is presented. The costs represent after-tax or effective costs realized by the owner of the energy system. The methodology addresses: (1) capital costs; (2) fuel costs; (3) maintenance and operating costs; (4) property taxes; (5) the tax benefits of depreciation; and (6) the investment tax credit. The model was developed for evaluating solar energy systems located at the point where the energy is demanded. However, the methodology also has applicability to many other types of energy systems.

Creating The Electric Energy Economy, L. G. Hauser
Creating The Electric Energy Economy, L. G. Hauser
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
My remarks will be directed to four points:
First, that energy is the life blood of our economy, and that its use or conservation is far from a simple matter of personal habits of waste or frugality. In other words, the vital role energy plays in the production of goods and services should be distinguished from its use in their consumption.
Second, that our excessive dependence on our two scarcest energy resources -- oil and natural gas -- is the core of the energy problem, both U.S. and worldwide.
Third, that limiting our time horizon to this winter, next summer, …
Energy And Transportation Policy, James S. Sagner
Energy And Transportation Policy, James S. Sagner
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy shortages of recent years suggest a re-examination of national transportation policy. The lack of a coordinated approach to the solution of urban cogestion inhibits potential short-run responses to gasoline shortfalls. Longer-range policy, particularly in the context of severe financial constraints, must be carefully integrated with demonstrated patterns of urban travel and population and employment densities. Given these considerations, metropolitan areas now planning or constructing rapid rail facilities may be selecting inappropriate responses to the problem of urban access.

Collector thermal performance is illustrated for typical operating and environmental conditions. A cost analysis is presented to demonstrate that material and assembly costs are substantially lower than for any collector presently on the market.
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy self-sufficiency for the U. S. requires substantially increased use of coal. Direct combustion of coal without adequate environmental controls, as would occur if coal were used as a fuel for homes and offices throughout the country, would result in severe air pollution problems„ Synthetic fuels from coal such as methane, low BTU gas, or hydrogen, when utilized by the homes and businesses as gas or as electricity from gas, will contribute a much smaller amount of air pollution. However, to make these synthetic fuels available, it is necessary to mine more coal than would have to be mined for …

Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado, Adel H. Eltimsahy
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Results of the investigation of the performance of solar cells when directly coupled to a conventional three-phase power network are presented. This approach dissociates the electricity production problem from the electric energy storage problem. Extensive studies of the required power inverter are performed. Preliminary simulation results indicate that ac power outputs of better than 90% of the optimum cell power output can be easily achieved by means of a suitably controlled inverter, thereby justifying the elimination of dc loads or local dc electric energy storage devices. It is also shown that the controlling policy for the inverter must depend on …

Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A series of models has been developed for regional studies of energy supply- demand systems. The models are based on dynamic simulation of components of the system using equations derived from the technical details of the system. The models contain sufficient detail to make in-depth studies and specific recommendations. The final goal is to include all aspects of regional energy systems from native supplies of energy resources to the economic activities of the region.
To develop a comprehensive model, the system has been partitioned into subsystems, so that a detailed model can be made for each subsystem. The detailed model …
