...Great gaseous bubbles of oil and blood erupted, bringing up torn bodies and a ghastly debris. Two diesel engines and the first two coaches lay 35 ft. under water. The third coach, hooked on a bridge abutment, dangled crazily at 80°. Down in the second coach, Broker Land, a nonswimmer, drifted to a small air pocket at the top of the coach and filled his lungs. "What a lousy way to die." he thought. Then he found a window, kicked it out, and surged suddenly up to the surface and a helicopter's rescue line...
Light Molecules. The simplest kind of atomic engine uses a nuclear reactor to heat a gaseous propellant and shoot it out of a nozzle. Its chief advantage over chemical rocket engines: its propellant can be liquid hydrogen, whose molecules are light and therefore move faster at a given temperature. The best possible chemical combination (hydrogen and ozone), burning at 5,000° F. and 500 lbs.-per-sq.-in. chamber pressure, gives an exhaust velocity of 13,000 ft. per sec. A nuclear rocket, using hydrogen at the same pressure and only 3,000° F., shoots...
Both Britain and the U.S. use complex machines that work in about the same way toward the same simple purpose: to heat gaseous deuterium (heavy hydrogen) as hot as possible and confine it in a small space as long as possible. When deuterium atoms get hot enough, they hit each other so hard that they "fuse," forming helium 3 (and a neutron) or tritium (and a proton), and give off energy. This process happens explosively in H-bombs, but to control the reaction, the deuterium must be confined. Since ordinary, solid walls cannot hold the gas at the necessary temperature...
...past two years Stanford Physicist Robert Hofstadter, 42, has been probing the neutron by firing electrons down Stanford's 220-ft. accelerator at target nuclei of gaseous hydrogen and other elements. The electrons bounced off, said Hofstadter, "like tennis balls thrown at a target...
Doctors have long fretted because peptic ulcer patients stubbornly ignored their warnings that sodium bicarbonate, the kitchen's ever-present help in time of heartburn, may cause alkali poisoning and dangerous gaseous distention of the stomach. But it remained for Glasgow's Dr. Andrew Greig Melrose to report, in the Scottish Medical Journal, a case of outright addiction to bicarb, an addiction so intense that the victim suffered severe withdrawal sickness when taken off the stuff...
