...around a circuit and used repeatedly, but jet engines or ram-jets poison the air with their exhaust gases. New air must be taken from the atmosphere, and its excess moisture eliminated. So the tunnel is provided with a monstrous air dryer stocked with 1,890 tons of activated alumina, which soaks up 1.5 tons (ten bathtubs) of water per minute. On a muggy day the alumina has to be dried out after two hours, and this takes enough gas burners to keep the whole city of Berea, Ohio (pop. 13,200) warm in winter. The air in the tunnel...

The alumina ore came in Alcan freighters from Jamaica through the Panama Canal to Kitimat's newly dredged harbor. In the Kitimat smelter, the power processed the alumina into the first 4O-lb. ingot of Kitimat aluminum. Now set to produce 180 million Ibs. of aluminum a year, Kitimat eventually can climb...
