Open-pit mining methods, like those used to get copper in Butte, Mont., may also be tested, probably at one of the Colorado tracts. Great earth-moving machines would first peel back the sagebrush and grass over thousands of acres, next remove billions of tons of earth and rock, and finally gouge out the oil-shale beds 100 ft. to 850 ft. below the surface. The other technique, to be tried at the remaining leaseholds, will be to deep-mine with conventional pillar-and-room tunneling, as is done with coal-but on a gargantuan scale. More than...
...COLC this week will probably allow aluminum, copper and zinc producers large-but limited-price increases in exchange for a pledge to use the added revenue to build more plants. Earlier, the COLC sought a similar agreement with the fertilizer industry. Fertilizer has been short partly because of a scarcity of ingredients, including natural gas, and partly because foreigners were buying up so much of what was produced domestically by paying $25 a ton more than the controlled U.S. price. Dunlop got only a grudging commitment that fertilizer firms would reopen a few shuttered plants and expand production at some...
Flaming Rowboat. To test his assumptions, Sakkas ordered the construction of dozens of flat mirrors that were covered with a thin reflecting sheet of polished copper. Each was about 5 ft. long and 3 ft. wide, small enough to be handled by one person. The Greek navy provided the men, the site and the target: a wooden rowboat with a tar-coated, plywood silhouette of a Roman galley attached to one side. When all was ready, Sakkas' burning-glass experiment took place early this month at the Skaramanga naval base outside Athens. After lining up 70 mirror-bearing sailors...
...Rippe's engines look as if they might have provided the angel Morani's means of levitation. There are about twelve of them, large ceramic pyramids crowned with shiny lengths of copper pipe and arcs of lavender plastic tubing. They bristle with brass nozzles and colored buttons and toggle switches. Overlaid on their basic gray-green, Boston beanpot color are gleaming red and blue zigzags, rows of tiny gold stars, and a gaudy, iridescent rainbow glaze. They have no discernible source of power and no visible moving parts, though at least one of them (The Rippe 1921 Virgin Gas Engine...
Though Saenz has given the highest priority to reopening Chile to foreign investors-he held at least 120 meetings with businessmen during recent visits to the U.S. and Canada-he stresses that the government will maintain tight control of its industry. Copper is, of course, Chile's chief source of foreign income. Under Allende's highly political management of the mines, which he seized from such U.S. firms as Kennecott and Anaconda, disastrous strikes badly hurt production. The government will continue to own the mines, but it is willing to negotiate at least partial restitution...
