Floating Power Pile. A teacup of water has enough nuclear power, potentially to drive a large steamship across the Atlantic Ocean. But physicists who have studied the problem believe that an atomic engine will be no teacup affair; the only method they have found to date for releasing nuclear energy is the fission of considerable quantities of a heavy element like uranium...
Assuming that the power source is uranium or plutonium, such an engine would require: 1) a chain-reacting pile of several tons (which would provide energy in the form of heat); 2) boilers and other equipment for converting the pile's heat into steam; 3) massive shields to protect crews from the pile's deadly radiation; 4) a conventional turbine...
...would also need equipment for: 1) removing the pile's "ash" (fission products), which slows down the chain reaction and eventually stops it altogether; 2) periodic repurifying of the uranium in the pile; 3) making repairs by remote control in case the battleship's engine broke down...
Then Mary got married, and set up school in 1904 in Daytona Beach, Fla. "on $1.50 and faith." Her first pupils were five little girls and her son. They used charcoal for pencils, mashed elderberries to make ink. The curriculum included manual training; her pupils repaired junk-pile furniture so they would have something...
...highest since 1920. Even with the bumper crops expected this year, most grain traders think that wheat will stay up there because of the world demand. Moreover, farmers were having a tough time getting their grain to market. The shortage of railroad cars had forced many of them to pile it up in the open fields alongside the tracks (see cut). At week's end, drenching rains had spoiled half the grain stored in some fields...
