...days in Italy. He brought along gas for his motor scooter, canned food, which he cooked over a portable stove with German canned heat, a tent, blankets, and other necessities for independent outdoor living. Cost of his trip: nothing. Said he: "The only thing I took from Italy was water from the public fountains...
...areas in the world could profit more from water than Tunisia's Sahel region, where some 4,000 farmers scratch out a living. But U.S. Development Loan Fund technicians argued that there was not enough water in the Nebana River to warrant building a dam. "It might be no more than a beautiful white elephant," said an observer...
Tunisians insisted that there was enough water underground which could be tapped by wells to supplement the river supply. DLF officials mulled it over. Finally, when President Eisenhower paid his brief visit to Tunisia last December, Bourguiba told him that a Soviet trade mission had suggested that Russia would be only too willing to help build the dam if the U.S. did not. The DLF sent an expert to make a study. He reported tnat the Tunisians were right: there was enough underground water. Last week DLF announced that it would lend Tunisia $18 million, enough to assure the building...
Cruising endlessly under water, the Navy's subs have a private atmosphere all their own in which a single supply of air is breathed again and again. Whenever the oxygen level gets low, huge high-pressure cylinders of oxygen refresh the air, and there is also an electrolytic cell that turns sea water into oxygen and hydrogen, shooting the latter out of the submarine. For emergencies, the Naval Research Laboratory has provided ingenious "candles" made of sodium chlorate and powdered iron. When they are ignited, they emit oxygen, not the carbon dioxide that is given off by ordinary candles...
...there is hydrogen, which emanates from batteries, can form an explosive mixture if as little as 4% accumulates anywhere. The smelly organic vapors from garbage and human sources must also be removed. Most of this unwanted stuff is eliminated by a hot catalyst that oxidizes it to CO2 and water. All traces of organic matter that escape the catalyst are mopped up by a bed of activated carbon, and finally an electrostatic precipitator removes the last aerosols (dust or smoke particles) from the sub's fresh, clean world. In case of an atmosphere-fouling emergency, the crew can plug...
