...consumers could also greatly accelerate research into ways of efficiently developing non-Arab sources of fuel. The Rocky Mountain shale and Athabascan tar sands of Canada may hold more oil than all the sands of the Arab deserts; some estimates run as high as 1.5 trillion bbl. Liquefication and gasification of coal could provide a low-polluting way of using that superabundant fuel. But the capital investment required is staggering: $5 billion to $7 billion to get 1,000,000 bbl. of oil a day out of shale or tar sands. Senator Jackson has been advocating a U.S. emergency research...
...reject the cynical view that politics is inevitably or even usually a dirty business. Let us not allow what a few over-zealous people did in Watergate to tar the reputation of the millions of ded icated Americans who fought hard but clean for the candidates of their choice...
...sabertooth's days were also numbered. Slower afoot than modern tigers and possessed of a smaller brain, the sabertooth could not keep up with speedier prey that might have assured its survival. Indeed, archaeological dating of the remains of sabertooths found in Los Angeles' Rancho La Brea tar pits suggests that the last sabertooths vanished from North America about 13,000 years...
...basic diet of microorganisms that can trigger a natural sequence of soil enrichment. Stanford proposes to plow cellulose-containing material in garbage into the desert soil. Next, he would fertilize it with "sludge," a purified end product of sewage treatment that looks like gruel, smells like tar and is loaded with nutrients. Using a little sewage water for irrigation, Stanford says, will then turn the desert into a vast garden. His theory makes eminent sense to scientists-and to Odessans, who believe him even when he rhapsodizes about Sunday strolls through the city's future "forests...
...needs. However, said Drake, "Our estimate is that the remaining proven conventional reserves of oil amount to 570 billion bbl." Sir Eric stated: "We believe there are potential reserves of another 1,080 billion bbl. In addition, we think we could get about 700 billion bbl. of oil from tar sands and another 3,140 billion bbl. from oil-bearing shale." Not all those actual and potential reserves are recoverable at current prices, he pointed out. Moreover, as several speakers said, some two-thirds of conventional oil reserves lie beneath Middle Eastern and North African countries, and all of them...
