...hundredth of the current capacity of conventional superconductors. And because the amount of current flowing through the magnetic field determines its strength, scientists are concerned that a quick fix may not be in sight. Warns GE's Robb: "What we need now is a second invention that would modify copper oxides to allow high currents to flow at high temperatures. There's a fifty-fifty chance that second invention will ever be made...
Take the transmission of electricity, for example. As much as 20% of the energy sent through high-tension lines is now lost in the form of heat generated as the current encounters resistance in the copper wire. If the electricity could be sent through superconducting cable, however, not a kilowatt-second of energy would be lost, thus saving the utilities, and presumably consumers, billions of dollars. Furthermore, at least in theory, all of a large city's electrical energy needs could be supplied through a handful of underground cables...
...bugs in the building will ever be found. To do so might require conducting what one expert calls a "destructive search" -- which means nothing less than tearing the building apart. But some optimists believe that at least some rooms can be made secure, mostly by shielding them in copper, lead or other materials that foil electromagnetic emissions...
...much sought-after goal proved to be elusive. In the early 1970s scientists found an alloy of niobium and germanium that lost all resistance at 23 K. Then, last April, a group at the IBM Zurich Research Laboratory in Switzerland announced development of a compound of barium, lanthanum, copper and oxygen that appeared to begin the transition to superconductivity...
...those loyalist forces helped Reagan sustain, although narrowly, a presidential veto of a protectionist trade bill that had passed both the House and the Senate. That bill took a piecemeal approach, among other things setting a new system of country-by-country quotas on imports of textiles, shoes and copper from such places as Taiwan, South Korea and Thailand...
