...plasma thermocouple differs little in principle from the well-known bimetallic thermocouple that has been in use for a century to measure temperatures. In a bimetallic thermocouple, two pieces of unlike metals are joined. When the joint is heated, a feeble electric current is generated, flows through a wire connecting the cold ends. Chief obstacle to commercial use is the difficulty in finding metals that can operate efficiently at the high temperature required for large-scale power production (TIME, April...
Under vacuum, cesium turns partly to gas. As the uranium heats up. it ionizes the cesium gas to a plasma of charged particles (electrons wrenched from their atoms). As in conventional thermocouples, there is a flow of electric current between hot and cold: from the hot (2,000° C.) junction of the uranium and ionized cesium to the cold (300° C.) junction of the cesium and the oil coolant...
Although the Society will ponder current and controversial topics, Green said that discussions would be for the sake of controversy itself rather than any hope of resolving issues. "What the club will be depends on who comes," he added, but already tutors and graduate students connected with the House have shown interest, "so the outcome looks propitious...
Williams is strongest where current American policy is weakest (in the uncommitted areas) and muddled where policy is sensibly firm (in direct relations with Russia). His analysis, although not completely convincing, is nonetheless provocative and worth while...
