...After the shale is mined, the rock is crushed. Union Oil then moves shale chunks through a towering surface retort, where hot gases heat it to release the kerogen. Colony uses a different process: it cooks finely ground shale in giant drums by mixing the marl with superheated, marble-size ceramic balls that distribute the temperature evenly and vaporize the kerogen. The balls are then separated from the spent shale by a screen, reheated and used again...
...second, more radical method involves cooking the shale underground. Occidental, which has pioneered this process, plans to dig at least 2,000 chambers connected by tunnels under a 5,000-acre shale tract leased from the Government. The chambers, each about the size of a football field and 250 ft. to 300 ft. high, are created by drilling parallel tunnels leading from a vertical mineshaft into the rock at two different depths. The shale in between is then reduced to rubble by explosions in both the top and bottom. Each chamber is sealed, and pilot-light burners are lowered...
Whatever extraction method is used, the investment will be enormous. Union's proposed 9,000-bbl.-a-day plant would cost $130 million; Occidental's 50,000-bbl.-a-day operation carries a $1 billion price tag. Colony's process, because of its size and capital investment, would be the most expensive: $1.5 billion to $2 billion...
...school performance follows Brecht's script faithfully, but does not venture into new or experimental theatrical terrain. The result is a bit spare, even stingy. In a major omission, Seoh leaves out the celebratory dance at the end of the play, perhaps because of the limited size of the auditorium. Such a formalistic rendering of the play shortchanges the audience...
While Kingberg is much smaller than the average defenseman, she makes up for her size with her speed--"I can force players to the outside if I can't make the tackle."--and her ability to fake. Also, Kingsberg has grown more aggressive over the past two years and has improved her kick so that now she feels confident at fullback...
