...help me celebrate, they issued us new helmets, made of one of the latest fibers -"Kevlar." It's very light and is supposed to be strong enough to turn away high-velocity frags like it was armor plate or something. The only trouble is, it looks like those coal scuttles the Germans wore in World War I. And I'm not so sure you could make stew...
...singing about them yet, but power company officials are whistling about 130,000 long-stemmed beauties they grew in an experimental greenhouse in Sherburne County, Minn. The structure needs no fuel: excess heat from a coal-burning electricity plant near by is used to keep temperatures in the 60°-to-75° range. Hot waste water from the plant is pumped into the greenhouse through pipes buried in the soil. The sponsors of the $700,000 experiment -the Northern States Power Co., the University of Minnesota and the Environmental Protection Agency-found its potential intriguing. Along with the roses...
Most of the coal to fire President Carter's energy program (TIME, May 2) will be shipped by rail. But if other states or Congress pass laws like the one signed by Texas Governor Dolph Briscoe Jr. last week, an increasing amount will be transported by slurry pipelines. Working much like toilets, the pipelines are supposed to "flush" a slurry mixture of water and pulverized coal from mine to market. When the blend gets to its destination, usually an electric utility plant, the coal is separated from the water by filter or centrifuge and used to heat boilers...
Briscoe's signature granted the right of eminent domain in Texas to a 1,100-mile slurry pipeline proposed by Houston Natural Gas Corp.-only the second slurry line in the entire country. It would run from coal fields in southern Colorado to an area just outside Houston, crossing rail tracks 28 times. Fearing competition from the $500 million slurry, railroads had refused to give up rights of way. That hurdle was overcome by the new legislation, and the pipeline could be pumping 15 million tons of coal annually to utilities in the Houston area by the 1980s...
...first coal slurry pipeline was used in London in 1914. Currently, the only one functioning in the U.S. is the Black Mesa Pipeline, which runs 273 miles from Kayenta, Ariz., to the Mohave Generating Station in southern Nevada. But since pressures are sure to mount on the nation's coal delivery system, four other slurry pipelines are in various planning stages, all in the West or Southwest...
