“…A curb weight of 2800 Ib (1273 kg), only 12% below the 1991 US average of �2180 Ib, is also assumed, but is �2.0-2.7 times as heavy as some four-to five-passenger prototypes. Indeed, a US car fleet averaging 2000 Ib and hence 50 mi/gal could be achieved by materials substitution alone (45); each 200-lb reduction improves fuel economy by �5% (46).…”

“…Though each prototype has individual design peculiarities, collectively they prove that cars more than three times as efficient as the world fleet can be at least as comfortable, peppy, safe, 18 and low in emissions as today's typical new OECD cars . Comparable opportunities apply also to light trucks (46).…”

“…The world's half-billion motor vehicles-12 times the 1945 fleet, and now consuming nearly half the world's oil-has grown by about 5%/y for two decades (46) . If this growth continues, we will run out of land and air long before we run out of oil.…”

“…In-car computers linked to computer-driven transmitters that suggest time-minimizing route changes are already under test in Berlin. Automatic proximity-control systems could safely pack 2-3 times as many cars per lane-mile and "save up to 20% of the fuel consumed" (46) .…”

Offering safe and convenient bicycle (and pedestrian) lanes or paths, and coordinating with public transit (so bikes can be taken on trains and buses or rented at stations) , enables bikes to carry 9% of all Dutch commuter traffic, and "in some cities, they account for more than 40% of all passenger trips" (46). In contrast, although 54% of working US residents work within five miles of home, only 3% bike to work.…”

The threat of serious, unpredictable, and probably irreversible changes in the earth's climate has moved from conjecture to suspicion to near-certainty (1). Denial is now confined to the uninformed (2). Yet the threat's cause continues to be widely misunderstood even by many experts on its mechanisms.Global warming is not a natural result of normal , optimal economic activ ity. Rather, it is an artifact of the economically inefficient use of resources, especially energy. Advanced technologies for resource efficiency, and proven ways to implement them, can now support present or greatly expanded worldwide economic activity while stabilizing global climate-and saving money. New resource-saving techniques--chiefly in energy, farming, and forestry-generally work better and cost less than present methods that destabilize the earth 's climate .In short, even based on energy-efficiency assessments by such organiza tions as the Electric Power Research Institute (the utility industry's think tank) and leading US national laboratories , most of the best ways known today to abate climatic change ("stabilize" the climate) are

p PACA. See Rodentia. PACIFIC COD. See Codfishes.PACIFIC EQUATORIAL WATER. An immense surface oceanic water mass, extending from Central America to the East Indies. It is broader on the east, extending from 20°N to 20°S latitude, but it narrows greatly on the western side of the Ocean. Its surface temperature range is 8-15°C (46.4 to 59°F), salinity range 34.6-35.15%, but both properties decrease with depth below the lower values.PACIFIC HIGH. See Atmosphere (Earth). PACKING (Absorption Column). See Absorption (Process).PADDLEFISHES (Osteichthyes). Of the order Chondrostei, family Polyodontidae, the paddlefishes resemble to some extent some species of shark. Although classified as Osteichthyes, they are a strange combination of cartilage and bone. These fishes are named for the rather tremendous paddle that is attached to the nose, equal in length to about one-third the length of the body of the fish. The small barbels under the paddle are reminiscent of sturgeons.Paddlefishes are known for very rapid growth and development. ~hen fully grown, a paddlefish may measure up to 6 feet (1.8 meters) m length, with a paddle an additional 2 feet (0.6 meter) in length and about 4 inches (I 0 centimeters) in width. Biologists have not determined the use for the paddle because the fish obtains its food by swimming with its mouth wide open. The main diet is comprised of crustaceans and planktonic organisms.Only two kinds of paddlefishes are known: (1) the Psephurus gladius, found in the Yangtse River valley; and (2) the Polyodon spathula, found in the Mississippi valley. It is considered to be an acceptable food fish. In the United States, the fish is sometimes called the spoon-bill, spoon-beaked sturgeon, and spoon-billed catfish, or simply spooner.PAGET'S DISEASE. See Bone; Dermatitis and Dermatosis. PAINTS AND COATINGS.Traditionally, paints and other coatings have been considered in terms of protecting and decorating buildings, houses, furniture, automobiles, toys, boats, machines, and the like. These products represent a large industry estimated at about $15 billion per year worldwide. Nevertheless, these kinds of coatings account for only I 0-15% of the total coatings industry.One researcher 1 has classified coatings in two technically defined categories.Type !~Products manufactured and sold with several coating layers.Examples are the aforementioned applications, but also include color photographic film, graphic arts films for printing, coated papers for printing, coated containers for food packaging, magnetic storage media for computers and audio/visual equipment, optical 'E.

Type JJ~Coatings that become an integral part or a key intermediary for a device or piece of equipment. Sometimes, the term core technology is used for such applications. There is a wide variety of coating products in this classification and would include photoresists for circuit board manufacture, thickand t...
