...stay. Announcing that the airlift would be stepped up once more, the U.S. commander, Brigadier General Frank Howley, declared last Sunday: "Tomorrow is the first day of spring. Neither the Soviet blockade at the Elbe nor winter's ice or snow have kept food, medical aid and coal from coming into the city. Attempts to scare the population have failed ... It must be clear even to the densest and most ill-willed Communists that their tactics are not succeeding...
...Alabama Power Co., cooperating with the U.S. Bureau of Mines in the $500,000 test, was donating 500,000 tons of coal, willing to see it all go up in smoke and flame. The initial rate of burn-up was only 50 tons a day. The test would probably go on for a year...
Every year, millions of tons of coal are laboriously mined (at costs averaging $2.50 a ton), dumped into ovens and distilled, producing gas. For 80 years, scientists have been thinking of producing the gas without bothering to mine the coal. Lenin, picking up a British suggestion, wanted to try it in Russia. Since his death the Russians claim to have produced this kind of cheap power in many places...
...mine, 55 miles northwest of Birmingham. (A small-scale test at the same site two years ago gave promising but inconclusive results.) A thermite bomb was exploded 160 ft. below the surface, at the bottom of a borehole at the south end of the seam. Running northward through the coal for 1,200 ft. were two parallel entries (tapped by additional boreholes every 300 ft.) through which air could be driven under pressure...
...limiting the combustion to the first 300-ft. stretch. The underground temperature went up to 900° F. Later it might go as high as 3,000° F. No immediate attempt was made to produce a useful, combustible gas: the first thing was to see how steadily the coal could be made to burn. Later, hot air, steam or oxygen could be fed into Borehole No. 1 to make a variety of gases with different chemical and thermal properties...
