...possibility of generating useful amounts of electricity by blowing hot gas between the poles of a magnet has long intrigued adventurous physicists. Many have tried to turn the trick, but until Dr. Arthur Kantrowitz, chief of Avco Corp.'s Everett, Mass.. laboratory, reported impressive progress last week, large-scale magnetohydrodynamic power seemed as improbable as its nonstop name...
...moving parts; yet it generates 1,350 kilowatts of electric power. Dr. Kantrowitz likes to say that his creation is just like an ordinary rotary generator, but simpler. In one sense he is correct: a conventional generator has electrical conductors (copper wires) that are spun in a magnetic field by a steam turbine. Their motion causes a current to flow through them. In an MHD generator the conductor is a hot gas (plasma) that has been ionized by having electrons knocked off some of its atoms. When the plasma squirts rapidly between the poles of a powerful magnet, a current...
...cost of labor increases, advertising is an indispensable substitute for the personal salesmanship of times past. The genial clerk who used to sell undecided customers with the assurance that "my own family uses it" is steadily giving way to the self-service shopping cart. Today, advertising is the magnet that draws customers into the nation's supermarkets and department stores, and the prime mover of human inventiveness. Emerson notwithstanding, a man has small inspiration to build a better mousetrap unless he can mass-produce it and shout to the world about...
...area in between has lost−in population and power, in industry, and even in intellect. Michigan, long the symbol of American industrial go-getiveness, last year got only 2.7% of the defense prime contracts (against 9.5% in 1951-53)-Illinois got 2%. The seaboard centers have been a magnet in a selective sense−the populations flocking to California are not merely the sun-seeking oldsters, and certainly not the Okies of the 1930s, but often the youngest and brightest, most proficient and promising, most ambitious and adventurous. The more daring the project, the more attracted they...
...Korean war, Glenn flew F9F5 Panther jets, again on ground-support missions. After going on several missions with Glenn, Ted Williams, the Red Sox leftfielder recalled to duty as a Marine pilot, declared flatly: "The man is crazy," Says Lieut. Colonel Edward Lovette: "We called Glenn ol' magnet tail because his plane was hit so many times in combat...
