...industry experts say price comparisons are misleading because the high-tech versions have properties that make them more comparable to materials such as stainless steel and aluminum, which can be even pricier. Those attributes give architects, engineers and builders far greater flexibility to use concrete's long-lasting thermal and acoustic properties in everything from pedestrian bridges to bus stations. That in turn contributes to big energy and other environmental savings. Some of the innovations are startling: the white concrete that American architect Richard Meier used for the Jubilee Church in Rome, for example, contains titanium dioxide, which keeps...
...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 other advantages, including setting much faster. That's giving architects, engineers and builders far greater flexibility to use the material's long-lasting, thermal and acoustic properties in everything from pedestrian bridges to bus stations - and, in turn, contributing to big energy and other environmental savings. Some of the innovations are startling: the white concrete used by American architect Richard Meier for the Jubilee Church in Rome contains titanium dioxide, which keeps the concrete...
Congratulations, guys, as heroes of the environment I would expect no less from France. But what about France's contribution to energy efficiency in solar/laser and mechanical dynamo power expertise, not forgetting France's fashion expertise for thermal underwear, socks and gloves and a lightweight oversuit with shoe gloves. Keep innovating, guys. Your country needs you, and so does our planet. If you need further support, remember marathon runner Mavis Lindgren who, at 78, recorded a VO2 max equal to the average sedentary 20-year-old. Aerobic exercise rocks, and offers no-risk economies to the health service...
...Americans from around the country coming together to build a wind turbine - the soaring symbol of green power - while a narrator spoke of the need to "repower America" by pushing politicians in Washington for a rapid switch to 100% clean energy in 10 years. Other ads showcased gleaming solar thermal plants, and other new clean technologies breaking the horizon...
...campaign promises to pursue an aggressive alternative energy program along with offshore drilling.) Without those tax credits, the renewable energy industry "is grinding to a halt," says Peter Duprey, CEO of the North American arm of the Spanish renewable company Acciona Energy, which has a 64-megawatt solar thermal plant operating outside Las Vegas, and recently launched a 180-megawatt wind farm on the border between North Dakota and South Dakota. "Everyone says America is the land of opportunity for renewables," says Duprey. "We have to get serious about...
