Sell-Off
In 1996, the city of Fairbanks, Alaska, offered its Fairbanks Municipal Utilities System for sale to private bidders. Four different entities assumed ownership of the water and wastewater,...
Advanced Seawater Desalination Plant
A project that will demonstrate an enhanced seawater desalination process that operates in combination with upgraded existing coastal power plants to meet part of the projected water needs...
Update of the Implications of Recent Space Resource Discovery
Immense resources have been discovered in the space near Earth during the last decade. Last August, 1992, one of the resource objects was discovered to contain a key ingredient that might...
Microworlds for Learning Through Inquiry
We discuss several computer-based environments to support learning through inquiry, called microworlds, including two focused on steam power plant operation and electronic troubleshooting....
High Speed Ground Transportation: Some Historical Perspectives
The definition of `high speed' ground transportation is relative to the transportation technology of a period. Thus it might be argued that high speed ground transportation began early...
Speedy Backfilling for Old Mines
In November 1992, the U.S. Bureau of Mines, in cooperation with the Office of Surface Mining (OSM), used two recently-developed pneumatic backfilling devices to completely fill an abandoned...
Steam Injection System for Lunar Concrete
Since January 1989, the Department of Civil Engineering at the United States Air Force Academy has been conducting research on the use of concrete for constructing permanent facilities...
Seawater Experimental Results of Direct-Contact Condensation for OC-OTEC Applications
Tests of a direct-contact condenser (DCC) for open-cycle ocean thermal energy conversion systems (OC-OTEC) have been conducted using seawater and exchanging up to 1.25 MWth...
Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...
Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO2 release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...
Real Time Modeling to Meet Flow Requirements at a Fossil Steam Plant
A real time modeling system has been developed to schedule hydropower operations in order to comply with discharge permit requirements at a downstream fossil steam plant. The modeling...
Energy Recovery
In Albany, N.Y. the state and city cooperated in designing and building a refuse-into-steam energy plant that has several unique features. In most such facilities, the entire plant is...
Operating Experience--Fine-Mesh Traveling Screens
Start-up and operating results for a new screenhouse at the Prairie Island Nuclear Generating Plant, 50 miles (80 km) downstream from Minneapolis/St. Paul, are compared to design assumptions....
Japanese Experience with Intake Designs
To diversify its power sources, Japan has operating or under construction some 37 nuclear power units. This technology and the design criteria are imported from the U. S. The power plants...
Dual Source Water Supply Facilitates Power Plant Start-Up
The make-up cooling water supply for a four unit coal-fired steam turbine generating station required a peak demand of 28,000 gallons per minute (62. 4 cubic feet per second). Following...
Dirt and Steam
Mechanization came late to the construction industry, and it was not until the middle of the nineteenth century that power earth moving machinery began to be used. Steam powered floating...
Automatic Steam Gathering Reduces Emissions at The Geysers
At the site of The Geysers, America's only geothermal power plant and the largest such plant in the world, the first completely computerized steam gathering system has been...
Harrisburg Pioneering Codisposal of Refuse and Sludge
Harrisburg, Pa. is doing something that sounds like common sense yet which has been done by very few communities in the U.S.: disposing of both its municipal refuse and sewage sludge in...
Recycling Refuse Into Energy
Some 50% of large cities, 10% of small ones reportedly are talking about recycling their municipal refuse. Several are building facilities or have recently begun operations. This article...
International Engineering Congress 1904
Topics covered: purification of water for the production of steam; mining engineering; harbors; engineering education; the light-house and other aid to navigation; the manufacturing of...
