SYNTHETIC FUELS. The vast resources of coal could be used to produce a variety of synthetic fuels. In coal gasification, for instance, coal is brought in contact with steam. Hydrogen atoms in the vapor combine with the coal's carbon atoms to produce a hydrocarbon similar to natural...
GEOTHERMAL POWER. Though underground reservoirs of steam and water have long been tapped in Iceland, New Zealand, Italy and Japan, the only large geothermal enterprise in the U.S. is a steam field known as the Geysers in California's Sonoma County. There, steam from deep in the earth drives turbogenerators that produce some 302,000 kw. of electricity, roughly 40% of San Francisco's total requirements...
...water. One proposal, under test by the AEC's Los Alamos Scientific Laboratory, involves sinking two side-by-side holes deep into the earth until they reach hot basement rock (approximately 1,000° F.). Then by pumping cold water into one hole, the scientists hope to extract steam from the other. Project Director Morton Smith reports that test borings to a depth of only 2,500 ft. (v. the final goal of 7,500 ft.) already have produced significant heating. Battelle Memorial Institute is proposing a similar experiment in Montana...
...technique, proposed by Aden and Marjorie Meinel, a man-and-wife team of scientists at the University of Arizona, involves spreading a "solar farm," consisting of piping containing a mixture of chemicals, over 25 sq. mi. of desert. Heated by the sun, the mix would be used to make steam, which would power turbines capable of producing some 1,000 megawatts of electricity...
...open meeting Thursday night that scared up only 22 graduate students, Union members declared that they had run out of steam and voted to postpone organizing activities until next Fall...
