...steel and shipping containers and priced as low as $76,000, not including land. And Frank Gehry protege Michelle Kaufmann recently debuted Glidehouse, a moderately priced modular home (averaging 1,350 sq. ft.), so named for a series of sliding panels that hide storage spaces and regulate light and airflow. Although prefabs account for less than 30% of new home construction, they are ushering in affordability with style. "Prefab is making good design available to the masses," says Jill Herbers, author of the book Prefab Modern, "and as more people discover it as an option, it will become a competitive...
Today's fleet is both more comfortable and safer than the generation of '70s-era Pontiac GTOs. Higher-tensile steels enable manufacturers to make frames that vibrate less and are stiffer and lighter (the bane of convertibles past was lumbering weight and rattle). "Airflow management" is now a priority--with windshields shaped to reduce wind so you can actually hear that nine-speaker stereo. And upscale roadsters like the Mercedes SL500 feature pop-up roll bars that can deploy in a third of a second. (Such bars, however, won't necessarily save you in a rollover. The National Highway Traffic...
...nausea and fainting. Poor air distribution led to still pockets of air forming at head height in parts of the airplanes, says BA, forcing some staff to work in conditions that were "like a hot day with no breeze." Boeing has said it is studying ways to improve the airflow. For passengers, too, air distribution has become an issue: many new planes no longer have individually controlled air ducts above their seats. About half the cabin air passengers breathe is recirculated, meaning it has been sucked out of the cabin, passed through filters and returned mixed with fresh air drawn...
Wind has the edge. It's fast catching up with oil and gas in cost efficiency with the help of experiments such as the one at Ames Research Center. By comparing what they learn from the wind tunnel's smooth airflow with data from the turbulent breezes at the National Renewable Energy Laboratory's test range near Golden, Colorado, engineers expect to build a new generation of superefficient wind turbines with blades well over 200 ft. (60 m) across...
...history is their guide, the National Transportation Safety Board (NTSB) staff will take a hard look at a problematic piece of equipment on the Boeing 767--the thrust reverser. These devices slow the aircraft down during landing by reversing the airflow from the engines. And while the devices are great for shortening landing rolls--or stopping a plane during an aborted takeoff--they can be deadly if accidentally deployed in flight. In 1991 a thrust reverser on a Lauda Air Boeing 767 deployed in midair, sending the plane into a death plunge over Thailand. That...
