...idea of a global shortage seems incredible when 70% of the earth's surface is covered by H2O. But 98% of that water is salty, making it unusable for drinking or agriculture. Desalinization is technically feasible, but it is far too expensive to use anywhere except in an ultra-rich, sparsely populated country like Saudi Arabia. Other options, like towing icebergs from the poles, are also beyond the means of poor nations...
...well runs dry. Several communities located near the sea have built desalinization plants. Denver, meanwhile, has pioneered the unsavory concept of turning sewer water into drinking water. In 1985 the city opened an experimental plant that produces 1 million gal. a day of high-quality H2O from treated effluent...
Environmentalists and engineers know that hydrogen would make a better jet fuel than the standard aviation kerosene. In its liquid form, hydrogen packs more energy per pound than any other non-nuclear fuel and, burning, produces a plume of H2O. But there are major drawbacks, including cost. Extracting hydrogen from water or natural gas and cooling it to -423 degrees F make the fuel many times more expensive than kerosene, which goes for about...

...dinner specials are the best introduction to Portuguese dining. Most seafood dishes consist of salty slabs of off-white flesh with tangy blobs of lemon sliding across the top and flanks of the deceased H2O breather. But the Casa's seafood is served up as a steamy, eye-tingling gumbo of rice and hors d'oeuvres-size bits of fish, mussels, shrimp or clams, all wrapped up in a deliciously meaty, spicy sauce which takes away the nasty oceanic tang that clings to most fish...
