Time resources represent our understanding of the time factor in our designing situation. This kind of resource not only includes times when our team members are available and when experts are available but also information about the timing of the construction and manufacturing of the individual structural members. It may also contain information on how much time is available for our project. Space resources provide information about available space for our system, access to it from various directions, penalties for using more space than originally assigned, and so on. 

Mining and Harvesting of Space Resources. Human settlements in space could help solve specific resource needs feced by humans on Earth, such as environmental and power needs. One proposed endeavor would be to use lunar regohth as a source of energy that could be beamed back to Earth through microwaves. Other possibilities include using the he-lium-3 found in the lunar soil as a fusion-power source to fuel rockets. If proper transport was arranged, helium-3 could also be used for Earth s power needs. Perhaps the most important use for resources found in space would be to sustain human settlements and help them become self-sufficient. 

The National Vision for Space Exploration (NASA, 2004) laid out by President Bush in January 2004, calls for a return to the Moon in preparation for the human exploration of Mars and other destinations. According to this plan, the Moon will provide an operational enviromnent for demonstrating human exploration technologies and capabilities within relatively safe reach of Earth. These capabilities included sustainable exploration techniques, such as the utilization of space resources, and human-scale exploration systems, such as power generation, surface mobility, and habitation and life support systems. In addition, lunar... 

Many computational chemistry techniques are extremely computer-intensive. Depending on the type of calculation desired, it could take anywhere from seconds to weeks to do a single calculation. There are many calculations, such as ah initio analysis of biomolecules, that cannot be done on the largest computers in existence. Likewise, calculations can take very large amounts of computer memory and hard disk space. In order to complete work in a reasonable amount of time, it is necessary to understand what factors contribute to the computer resource requirements. Ideally, the user should be able to predict in advance how much computing power will be needed. 

Direct Uses of Geopressured Fluids. Many of the uses typical of hydrothermal energy, such as greenhouse, fish farm, and space heating, have been proposed for geopressured resources, but none has been commercially developed (34). Hydrothermal fluids are widely used in enhanced oil recovery, however, to increase production from depleted oil fields. 

On the positive side, the three-dimensional nature of the resource provides it with a distinct advantage compared to other solar technologies. Specifically, because siting usually involves placing the individual turbines as high as possible, typically spacing turbines about 2 to 3 blade diameters apart crosswind and 10 diameters apart downwind, only a small fraction of a wind farm area is actually occupied. The rest of the land remains available for other appHcations, such as crop production or Hvestock grazing. 

There are four principal ways ia which biomass is used as a reaewable eaergy resource. The first, and most common, is as a fuel used directiy for space and process heat and for cooking. The second is as a fuel for electric power generation. The third is by gasification iato a fuel used oa the site. The fourth is by coaversioa iato a Hquid fuel that provides the portabiUty aeeded for transportatioa and other mobile appHcations of energy. Figure 7 shows the varied pathways which can be followed to convert biomass feedstocks to useful fuels or electricity. 

The EPA I.D. Number is a 12-digit number assigned to facilities covered by hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA). Facilities not covered by RCRA are not likely to have an assigned I.D. Number. If your facility is not required to have an I.D. Number, enter not applicable. NA, in box a. If your facility has been assigned EPA Identification Numbers, you must enter those numbers in the spaces provided in Section 3.8. 

A basis set is a mathematical representation of the molecular orbitals within a molecule. The basis set can be interpreted as restricting each electron to a particular region of space. Larger basis sets impose fewer constraints on electrons and more accurately approximate exact molecular orbitals. They require correspondingly more computational resources. Available basis sets and their characteristics are discussed in Chapter 5. 

Infill drilling is another possible way to extend production. For a variety of reasons, some oil may not be available to the original wells in the resei voir. Some wells may be spaced too far apart to capture the oil between them. Gas or water flooding may have bypassed some oil, or fractures or faults may block off certain parts of the reservoir from the rest so that they cannot be drained from existing wells. In these cases drilling new wells between existing ones call be an effective way to capture more of the resource. 

The first experiments with the thermal electric engine were conducted in Russia in 1929 by its inventor, Valentin P. Glushko, who later became a world-famous authority in rocket propulsion. For more than forty years, the United States and Russia have devoted many resources to research and development of various kinds of EREs. First tested in space by the Russians in 1964, these engines have found some limited applications in modern space technology. For more than two decades Russian weather and communication satellites have regularly used electric rocket engines for orbital stabilization. The first spacecraft to employ ERE for main propulsion was the American asteroid exploration probe Deep Space 1, launched in 1998. The performance of...
