...anyone who has dropped a dinner plate knows that ceramics do not. And a flexible material has a big advantage over a brittle one if it is to be coiled around an electromagnet. Says Osamu Horigami, chief researcher at Toshiba's Energy Science and Technology Laboratory: "To get a magnet or coil or even a wire we could use with complete confidence could take another five years." Agrees Hulm: "It will take extraordinary engineering to solve the brittleness problem...
...sense of triumph." Argonne Ceramist Roger Poeppel now talks of building a furnace ten feet long to fire his group's wire almost continuously as it is extruded. "We think it will be flexible enough to twist into cable," he says, "and cable is the building block for magnetic coils and electrical transmission lines. With two miles of wire, we'll make a superconducting magnet. To get a practical device + is now the race...
...professional journals -- of new superconducting materials and ever higher temperature ranges. An effect that once could be detected only with sophisticated equipment has become a common sideshow at conferences: a sample of one of the new materials is placed in a dish of liquid nitrogen, and a magnet placed above it. Since superconductors repel magnetic fields, a phenomenon called the Meissner effect, the magnet remains suspended in midair...
High-temperature superconducting magnets may become important in the maglev, or magnetically levitated, trains under development in Japan and West Germany. And scientists at Japan's Mercantile Marine University in Kobe have already developed a working scale model of a ship with a propulsion system based on magnetism. Physicist Yoshiro Saji sends current through the seawater from an onboard electric generator via ship-bottom electrodes. A superconducting magnet, also on board, creates a strong magnetic field. As the electromagnetic field produced by the electric current pushes against the field of the magnet, the ship moves forward. Saji has already moved...
...increase of 115% over the same period in 1985. Two attractions: Spain's low labor costs, which run 15% less than the European average, and the country's large population of consumers (39 million). Says Courtenay Worthington, Citibank Espana's general manager: "Spain is becoming a magnet for foreign investment. Many companies are putting up money, and those that aren't are wondering if they should...
