The Energy Conservation And Safety Dilemma, Burns E. Hegler Oct 1980

The Energy Conservation And Safety Dilemma, Burns E. Hegler

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Since the beginning of the energy crisis, efforts to conserve energy often have seemed to be diametrically opposed to the precepts of safety. This is true if conservation is not planned and conducted properly. However, energy and safety can be quite compatible and may work to their mutual advantage if effectively managed.


Superconducting Magnetic Energy Storage: A Cost And Sizing Study, Haur D. Shaw, J. Derald Morgan, Max Darwin Anderson Oct 1980

Superconducting Magnetic Energy Storage: A Cost And Sizing Study, Haur D. Shaw, J. Derald Morgan, Max Darwin Anderson

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Two applications for superconducting magnetic energy storage (SMES) devices in power systems are studied. One is for peak shaving, and the other is for load leveling. Consideration is given to placing these devices near load centers to reduce the line losses. For (SMES) cases studied using smaller size devices at several load centers, the line losses are lowered. However, the efficiency of SMES is proportional to its size, and the capitol cost per MWH is much greater for a smaller size SMES unit when compared to a larger SMES unit. Once the location or locations for SMES have been selected, …

The Solar Connection -- Promise Or Peril?, Paul S. Strong Oct 1978

The Solar Connection -- Promise Or Peril?, Paul S. Strong

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

During the past decade important progress has been made in understanding the sun-earth environmental system. Modern observations of solar activity document changes in solar output over time scales ranging from seconds to decades, and evidence for longer term variations have been found in historical records. It follows that the sun cannot be considered to be a totally non-variable energy source. Continued research progress into solar-terrestrial interactions will hopefully provide an understanding of sun-weather/climate relationships resulting in energy conservation through more efficient energy utilization of our planet's atmospheric energy system.


Commercially Available Vacuum Tube Solar Collectors, Stanley J. Ring Oct 1978

Commercially Available Vacuum Tube Solar Collectors, Stanley J. Ring

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Efficiencies on the order of 50 percent with high differential temperature (150° C) have been advertised with the current distribution of commercially available evacuated tube collectors. Product specifications and, where possible, experimental data have been gathered and presented. The paper also develops a mathematical model for evaluation of these collectors. Results conclude that, although performance is high, collector expense limits the cost effectiveness to necessary high-temperature, high-volume applications. These include both residential cooling and industrial processing.

Application of economic criteria to modeling also enables the analysis of alternate designs in terms of their installed and operating costs, as well as allowing calculation of payback periods for the various system configurations.

This program was intended to aid in the design of solar hot water collector systems. Design parameters of the system are used as inputs to the program. System configuration and design can then be …


To Light Or Not To Light? -- That Is The Energy Question, J. Byron Nelson, Burns E. Hegler Oct 1978

To Light Or Not To Light? -- That Is The Energy Question, J. Byron Nelson, Burns E. Hegler

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The controversy over lighting levels has existed for some time. Interest in methods of lighting has been heightened by the energy crisis. It has been estimated that lighting consumes approximately five percent of the nation's energy, therefore lighting is a relatively small energy user when compared to transportation and industrial processes which consume the bulk of the nation's energy. However, any saving that will make a contribution to the energy crisis should be considered. Consequently, this paper shows how energy for lighting may be reduced without sacrificing the present quality of lighting and in some cases, actually improve the lighting …

Combining Solar Heating With A Wood Burning Furnace, Kenneth Bechtold, William E. Stewart Jr.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The objective is to minimize the use of high-cost heating fuels in rural areas with the assistance of a wood burning furnace and a solar collector.

It was discovered that when the output of a wood burning furnace can be diverted into a solar storage battery, more useful heat can be supplied to a house with little extra inconvenience to the homeowner. The total amortized system of the wood burning furnace combined with the solar system will be less than if the systems were operated independently.

A Solar-Cooling Pool Assisted Heat Pump System, Walter J. Schaetzle Oct 1978

A Solar-Cooling Pool Assisted Heat Pump System, Walter J. Schaetzle

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A swimming pool is used in parallel with a water-source heat pump for both cooling and heating. For cooling, the pool is used as a spray pond (cooling tower); and for heating, the pool is used as a solar collector, and thermal energy storage. Both theoretical studies and experimental work have been done on this system. A full scale system is almost complete and has been used during the summer for cooling. Economically, on both an operating basis and a capital basis, the system appears feasible.
