...bills climbed out of sight last winter. When President Carter in April proposed homeowner tax credits for installing insulation, Coleman figured he could at least afford to make his four-bedroom house more energy efficient. But when he went to the lumber store to buy 750 sq. ft. of fiber-glass insulation for his attic, he could not get one square inch. The store had been sold out for weeks, and no one had any idea when new shipments would arrive. Gripes Coleman: "It's ridiculous. I've been waiting for nearly three months, and now winter...
Since midsummer, a nationwide shortage of insulation, fiber glass and rock wool, has turned the fuel conservation plans of tens of thousands of other Americans into near-impossible dreams. Fiber glass today no longer comes only in the familiar batts (rolls) tacked up between wall and ceiling joists; it has also largely replaced rock wool as the preferred fluffy insulation material blown into wall spaces...

...feels like a ton (actual weight: 3 Ibs. 4 oz.) and a soldier has to hold it on when he runs. At last, relief is in sight. The U.S. Army Research and Development Command at Natick, Mass., is field-testing a new design. Made of a high-strength organic fiber, it features a flattened top and "skirts" that come down over the ears and nape of the neck; it looks unnervingly like the German model of World War II, but offers 30% more protection against shrapnel than the old Ml. The weight is about the same but it comes...
...Dietary fiber, said Dr. Ruth M. Kay of the University of Toronto, consists of those parts of edible plants that are resistant to the human digestive enzymes, so that they pass through the system virtually unchanged until they encounter bacteria in the large bowel. There are three basic kinds of fiber. The simplest is cellulose; the four-chambered stomach of cattle can readily digest this form, but the single human stomach cannot. Next comes a group of polysaccharides, consisting of complex sugar chains. The third type is lignin, which not even intestinal bacteria can degrade. Fiber of any kind provides...
