Coiled Tubing. The new steamer, a brainchild of William Lear, developer of the Lear Jet, supposedly has none of the liabilities of the old. It is powered by an external-combustion motor (which burns fuel outside the cylinders), uses yards of coiled tubing instead of an old-fashioned steam boiler and a special chemical preparation (to prevent freezing) instead of water. The fluid is sealed in, so it can't boil away. It is superheated to vapor by a burner that, according to Lear, "can burn anything from ground camel dung to high-grade gasoline"-although he recommends kerosene...
...smaller second motor-a plain steam turbine-will power the car's auxiliary systems and cut the time required to fire the boiler to 15 seconds or so. Although Lear's car has not been road tested (the auxiliary motor is not completed), the main power plant has been "run in," and Lear claims that it can generate up to 500 h.p. More important, since the fuel used to fire the boiler is burned rather than exploded (as it is in a gas engine) the car will leave practically no products of incomplete combustion behind to pollute...
...hearing specialists used to worry about loud noise as a cause of deafness only in industrial and military situations. They knew that eight hours of daily exposure, year in and year out, to the din of the proverbial boiler factory would eventually result in permanent, irreversible hearing loss. Riveters were particularly susceptible. Then they learned that the same thing happened to aviators. And after the advent of jets, the hazard applied to ground crews at airports and flight-deck personnel aboard aircraft carriers-hence the introduction of insulated, noise-absorbing plastic earmuffs...
...injured in the blaze, which broke out at 1:30 a.m. Fire Department officials said that a faulty heating unit--probably a defective boiler--caused the fire...
With Western clothes on, the Masai may lose their lucrative business of posing for camera-carrying tourists for a 1-shilling (14?) fee; they adopt a menacing pose for 2 shillings. Nyerere, who himself usually wears a Chinese-style boiler suit, does not seem to care about the tourist revenues that he may lose. His policy reflects not only the prudish nationalism of his socialist state but a black backlash against foreigners who, Mkwang'ata claims, romanticize the Masai as "walking, talking specimens of the noble savage." However, as an English-language newspaper, the Tanzania Standard, points out, Nyerere...
