...Germany and France, the industrial nations of continental Europe have boosted their gross national product 100% (to $212 billion) in ten years, turn out 250 million tons of coal (17% of the world total), some 65 million tons of steel (20% of the total), 1,500,000 tons of copper, zinc and lead (16% of world total). Across the English Channel, Britain's economy this year alone grew some 8% to $68.8 billion...
...fact. "Too often," he explained, "one group of people makes the theories while another assembles the facts." His early work was done in "partial theory," by which the market is dissected and sections of it studied. Such problems as the market effect of a change in the price of copper, or an increase in the supply of meat, were tackled by him and his co-workers during these years...
Electric-power production is a conservative business; it makes electricity just as it did more than a century ago-by driving copper wires through magnetic fields. That is all that happens in the huge, spinning generators of a power station. The rest of the massive apparatus-furnaces, boilers, turbines, condensers, etc. -is only to make the generators spin. Last week Avco Corp. described an infant invention that may grow into a wholly different and more efficient way to generate electricity...
Avco's apparatus, called a magneto-hydrodynamic (MHD) electric generator, works on the principle that any conductor of electricity that is moved through a magnetic field will generate in itself a current of electricity. This applies not only to copper wires (as in conventional generators), but to gases, which become conductors when they are made so hot that some of their atoms separate (ionize) into electrically charged particles. If forced through a magnetic field, a stream of ionized gas causes an electrical current to flow across it. This principle has been known for years, and many efforts have been...
