...when it was slathered over Western cities in the 1960s, but newfangled, bright - and still relatively expensive - concrete that has come onto the market this decade. High-performance or ultra-high-performance concrete, as it's known in the industry, is up to 10 times stronger than regular concrete. Although, pound-by-pound, it costs several times as much as regular concrete, industry officials say price comparisons are misleading because the high-tech versions have different properties that make them more comparable to materials such as stainless steel or aluminum - which are often more expensive still. The latest concretes have...
...High-tech concrete is just one of the products that has emerged from the research and development labs of cement, steel and chemicals firms this decade, and it signals a growing commitment by heavy industry to the notion of "sustainability." As public pressure has grown to reduce energy use and carbon emissions - and in general tread more lightly on the environment - companies in these industries have poured money into R&D efforts. Much of the work has focused on internal processes, especially on the critical task of finding out how to cut down on emissions during manufacturing. But in their...
Bijlsma runs the consumer luminaries business for Dutch company Royal Philips Electronics. He's feeling particularly upbeat these days because he's about to launch a new line of high-tech products that use only a fraction of the energy of traditional lighting. The oblong object he's holding is a table lamp. It's just one of 50-plus lighting fixtures (luminaries, in the industry jargon) in a new range based on the latest in digital light-emitting diode (LED) technology, which can produce a warm, white light that comes close to rivaling halogen lamps but uses only...
...aren't cheap - they can range up to $800 - but as "fuel costs rise, the payback improves," notes Trethewey. A good auditor will use a blower test, which lowers the air pressure inside a home - air from the outside will then rush through openings, revealing any leaks. A truly high-tech test will use thermographic cameras, which detect infrared light, to detect exactly where heat might be leaking...
...surge in bluefin-tuna-fishing over the past decade has been driven by the proliferation of sushi restaurants across the world. The bluefin industry, once the province of rustic local fishing fleets in the Mediterranean, was last year worth about $1.6 billion. Today tuna fleets use high-tech spotter planes buzzing over the Med during the summertime tuna-spawning season in search of shoals that have escaped the trappers. The industry's major players are massive multinational corporations like Mitsubishi, the world's biggest tuna trader - Japan imports the bulk of bluefin tuna caught in the Med. Some...
