UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The status of the residential heat pump industry is reviewed. Some potential improvements in energy efficiency, operational reliability, and initial cost are described and delineated. These possible innovations include two-speed or variable speed compressors, reliable defrost initiation and termination, improved system components, modifications to the basic thermodynamic cycle, add-on-heat pumps, solar assisted heat pumps, annual cycle energy system, chemical heat pumps, and gas fired heat pumps.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy, technical, social, political, economic, and environmental problems are all people related problems which will continue to increase along with the world's population. With the growing demands for more energy and minerals along with the constraints of protecting the environment, new approaches must be considered to these complex problems.
Energy sources, modifications, alternatives, and new developments must be considered for the present as short term resources (next 25- 30 years) and in the future as long range research necessary to develop and implement new technology (25 years on). Major energy sources and their environmental considerations are generally classified as:

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand
Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand
Masters Theses
"Presented herein is a brief analysis of the economic justification practices of the Corps of Engineers as commonly implemented in proposals concerning water resources projects. Where applicable, recommended methods are compared to similar methods advocated for, and accepted by, private engineering firms in similar situations.
The major problem exists in the lack of a profit motive in programs undertaken with the use of public funds. However, a profit can be said to have been realized in public works programs if the total benefits of the programs to all the people exceed the costs of these programs and, further, if the …
