The Pacific Intertie: 1970

Article Abstract:

The Pacific Northwest-Southwest Intertie, an 846-mile high-voltage dc transmission line from the Bonneville Power Administration in Oregon to Los Angeles was completed in 1970 and provides more than one-third of the city's power. The goal of the project, first seriously proposed in the 1930s, was to convey cheap Northwest hydroelectric power to the fast-growing Southern California region. Bonneville Power Administration head Charles F Luce had the major role in promoting the project in the President Kennedy and Johnson administrations, with Sweden's Asea Co electrotechnical Dir A Uno Lamm providing the design concepts. Asea and General Electric formed a firm, Joint Venture, which eventually build the dc lines. A complementary ac transmission system was built by a consortium of power firms and government agencies. Details and problems of system implementation are described.

On the front lines of the pay phone war at New York Telephone

Article Abstract:

New York City has 58,000 public phones on the street. New York Telephone owns 8,000 of them. The company logged 160,000 problems with them in 1989, 59 percent due to vandalism. Only 250 arrests were made in connection with the damage, which cost $10 million. The company is beginning to use technology to correct the problems sooner. New microprocessor-based internal-diagnostic circuitry in about 12 percent of the pay phones now automatically notifies a host computer when problems occur. New coin detectors built by Mars Electronics are being installed to thwart the use of slugs. The detector identifies coins by magnetic field, instead of by weight and size.

Are they watching Milton Berle on Mu Arae III?

Article Abstract:

The search for extra-terrestrial intelligence (SETI), though not successful, has provided new information about the Universe. SETI projects require specially designed equipment that can receive radio signals originating from different astronomical bodies. The decoding of these signals may reveal the origin and development of life on the Universe. A few of these signals help identify new astronomical objects and explain their evolution.
