Vent dampers. Before a furnace or boiler can heat a house, it first must heat itself. Only after the inside temperature climbs to about 130° F does the furnace begin transferring warmth. Yet whenever the system shuts off, much of the accumulated heat within the furnace escapes up the flue. The vent damper is an electrically operated plate that blocks the flue during an oil-or gas-burning furnace's off cycle, thus retaining the heat. The plate then rotates to an open position when the unit trips on again. Department of Energy studies show that dampers...
This winter, when the weather outside is frightful, it may not seem much better inside: thermostats must by law not be set above a chilly 65° F in offices. The best defense against 9-to-5 frostbite is clearly the layered look. At the risk of violating stodgy dress codes, men are buying sweaters and knit vests to slip under suits.

Impulse buying is on the wane. "Shoppers are more...
...controversy surrounding Aramco underscores the internal tensions within the U.S. over the nation's alarming dependence on foreign crude. The oil industry must have billions of dollars to expand U.S. drilling, exploration and other energy-producing investments that are needed to escape OPEC's hold, and Aramco's megaprofits are a big help. But to ensure those profits and continued access to foreign crude, the company has to walk a finer and finer line between the steadily diverging interests of producing and consuming states...
...Interior Department has required the companies to take costly environmental precautions in the area. Oilmen will mount their rigs on artificial islands built of gravel. Those located in water depths of more than 42 ft., the Government insists, must be left unused for two years, to see if they can withstand the ice; moving ice packs could knock over the rigs, causing oil spills. Moreover, the companies will be allowed to drill only five to seven months each year, starting in November. Reason: at other times the big bowheads, which weigh as much as 45 tons, migrate through...
