...Pollution-Toward a Cleaner Car" [Oct. 17]: natural gas is certainly a clean-burning fuel. However, for automotive use it must be stored as a cryogenic (supercold) liquid in a large, well-insulated tank. Unfortunately, if you do not drive a large number of miles in a relatively short time, the liquefied natural gas boils off. If your car sits in the driveway for a few weeks while you're on vacation, you may return to find your fuel has evaporated. Not only is this bothersome and expensive, but I suspect this evaporated hydrocarbon fuel may pollute the atmosphere...
...cell's hydrogen and oxygen are both stored in spherical tanks in a supercold liquid state. Warmed by electric heaters, they turn to gas, build up pressure and push themselves into the cells. And those heaters are among the least complicated devices on the spacecraft: a filament of gold-plated wire curving around the tank. The same type of device is a veteran of all the manned Mer cury and Gemini flights, being used to convert liquid oxygen into gas for the astronauts to breathe. When oxygen pressure started falling in Gemini 5, it was a sure sign that...
...With a probe-or sometimes with two, one in each lobe-held at this freeze level for 15 minutes, Dr. Rand's group has safely achieved the desired degree of pituitary destruction in more than 50 cases. Other neurosurgeons agree that for the pituitary, the supercold technique is "superior to all the rest"-such as scooping out the pituitary with a tiny, long-handled spoon, always with the danger that too much of the pituitary would be left...
Medical researchers have not yet found the cause of the disease, but surgeons have succeeded in treating its symptoms. New York's Dr. Irving S. Cooper uses supercold liquid nitrogen to destroy an area of the brain that is responsible for the patient's characteristic tremors...
