The Prediction Of The Optimum Performance Of Venturi-Type Wind-Energy Concentrators, J. A. C. Kentfield

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

A simple theoretical analysis is presented which allows the optimum performance to be predicted for venturi-type wind-energy concentrators. The results of the analysis are presented in convenient parametric form in such a manner that, for example, the influence on optimum performance of reducing the outlet area of the exit diffuser, an obvious means of reducing the bulk and cost of a venturi-type concentrator, can be established directly from the curves. It is shown that the most important parameters affecting concentrator performance are: the effectiveness of the exit diffuser, the area ratio of that diffuser and the magnitude of the base-drag …

Low Btu Producer Gas -- A Fuel Of The Past And A Fuel Of The Future, Lee Carter

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

A prime purpose of this paper is to give conscious emphasis to an important type of coal gasification, one that does not demand hundreds of millions of dollars to launch an experimental program but instead is essentially ready to use after a reasonable and straightforward engineering check-out of the local coal sources and the prospective gas demand.

That type of coal gasification results in low Btu producer gas. This paper deals with its history, its technology and its economics. In the light of that information, the future of low Btu producer gas in America then is assessed.

The Advantages Of Local Extremes Of Systems When Considering Energy Supply Trends Toward Size And Complexity, Harold A. Kurstedt Jr., Arthur M. Squires, William A. Kramer

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

Recent discussions of new energy sources, including some debate concerning the relative merits of a number of approaches, reflect an emerging trend toward extremes in size and complexity of sources. This trend is justified as a fundamental premise for future energy development. The trend is related to similar trends in commerce, business, medical service, and transportation. The recent sharp increases in marginal energy costs, along with governmental intervention in the energy scene, are accelerating a focus on the concept of an energy park, at one extreme, and on small locally-controlled sources of energy, at the other A key to successful …

Luncheon Speaker -- Future Energy Needs: Myths Vs. Reality, Margaret N. Maxey

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

It is self-evident that energy is that kind of power which generates and sustains a vital, dynamic, complex, industrial, social organism. Considered in and of itself, "energy" is not the kind of power we commonly call "political!' But in less than a decade, we have seen how rapidly and easily "energy" has been turned into an instrument for generating and sustaining a form of political power as pervasive and far reaching in its vital effects as energy itself. Those in an officially-sanctioned position to devise, impose and enforce an "energy policy" for a nation or a globe of humankind. As …

Carrying Water To Newcastle, Lloyd Lore Wartes

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

Western coals, now being shipped by unit trains to eastern and southern markets, contain from 13% to 32% moisture. Drying of these coals at the mine would reduce the cost of coal to the utilities from 10% to 16% IF the railroads do not materially increase rates on higher BTU coal.

The spontaneous combustion of dry coal can be inhibited, and the savings per unit train should range from $1,375,000 to $4,129,000 per year according to the various minimum tonnage rates. The shipment of dried coal will reduce the tonnages being shipped by 15%, or increase the railroad carrying capacity …
