...moved in, said Lefkowitz. Knowing the stock was astronomically overpriced, they began selling short. Among those known to have sold short, said Lefkowitz, were two ex-convicts, Sidney Barcley and Morris ("The Weasel") Miller, who got one-year prison terms in 1958 for SEC violations involving Canadian oil and uranium stocks. After the price plummeted, Barcley made the rounds of sweating brokerage houses offering "mob money" to bail the brokers out and take over their businesses...
...those substances." The dwindling of usable supplies of fresh water is being matched by steady progress toward a cheap method of desalinizing sea water; nuclear energy has dispelled the neo-Malthusians' favorite bogeyman of exhausted coal and oil deposits; and should the earth's supply of uranium ever be used up, men could turn to solar energy-which is already used in Japan to operate 200,000 water heaters...
Largely a brainchild of Dr. Weinberg, the reactor HRE-2 (for Homogeneous Reactor Experiment No. 2) is an attempt to avoid some of the worst disadvantages of solid-fuel reactors. Since solid uranium is quickly corroded at high temperature, it must be enclosed in a more resistant metal such as zirconium or stainless steel. As the uranium fissions, it generates gases that tend to burst the container. Other fission products absorb neutrons, and when too much of this "poison" has accumulated, it makes the nuclear reaction slow down or stop. At intervals, the fuel elements must be removed and their...
...fuel is uranyl sulphate dissolved in heavy water (which does not absorb as many neutrons as ordinary water). When this solution is flowing in a small-bore pipe, it does not react, because the fissionable uranium atoms are too strung out to form a critical mass. But when the fuel solution flows into a spherical reaction chamber, the compact mass becomes critical. A nuclear chain reaction starts, and heats the solution. Before the reaction goes too far, the solution is sucked away by pumps and forced through a heat exchanger, where it heats ordinary water to produce high-pressure steam...
Better Football. Crisscrossing the route of the spacemen, an equally eminent group of nine Russian atomic scientists was also touring the U.S. Led by Professor Vasily S. Emelyanov, chief of the Soviet Administration for Peaceful Utilization of Atomic Energy, they visited laboratories from California to Long Island, uranium mines, nuclear-power reactors and the nuclear merchant ship Savannah, now under construction at Camden, N.J. The prime matter on Emelyanov's mind seemed to be peaceful atomic cooperation between Russia and the U.S. The two nations are now engaged, he said, in a "football game" of senseless competition, but they...
