...returning to Harvard, almost half of V.T.A.'s participants have written theses dealing with Africa or have gone away to graduate school in African Studies. This year, one former member is going to the Ivory Coast as a geologist, another is in Zambia as an educational evaluator, a third is working with African students...
...until last November, though, did anyone offer reasonable answers. Then Consulting Geologist David Evans suggested that the quakes under the suddenly shaky Colorado terrain could be traced to a deep well at the nearby Rocky Mountain Arsenal. Military and civilian experts scoffed, but Evans backed up his theory with impressive evidence...
...determining melting points of iron (and all other substances that increase in volume as they melt), scientists have long used Lindemann's Law, a complicated mathematical formula describing the relationship between the melting temperature of a substance and the pressure upon it. But Geologist Kennedy was disturbed by the widely varying and apparently inaccurate results obtained when the law was applied at higher pressures. He decided that something was wrong...
...Yugoslav Geologist Bozidar Djordjevitch had an ingenious idea. Every spring, he said, water from melting snow pours into Yugoslavia's Karst caves, compressing air that whistles out through vents in the earth's surface. Why not seal the caves and funnel the escaping air to gas turbines, which could convert it into useful energy? Djordjevitch soon had an answer: the caves are vented in too many places; they are almost impossible to seal...
Pumping Water Up. Geologist Martini already had evidence that his scheme would work. There was no doubt that compressed air could be stored underground; it is often used for testing the sealing of caverns that many nations use to store natural gas. In addition, off-peak-hour electricity is already used to pump water up into a reservoir above the level of a water-driven turbine. During hours of peak demand, the water is released to flow down against the blades of the turbine, which drives an electric generator...
