...explaining blog vocabulary (CAPTCHA; commenter; troll; vlog), as well as various means of measuring traffic (hits, page views, unique visitors). Surprisingly, the book is congratulatory towards Arianna Huffington without taking a completely hagiographic tone. A must read for blog newbies, of which there are increasingly few. Ironically, the tech savvy reader could probably find much of this information somewhere online...
Alternative (or "complementary") currencies range from quaint to robust, simple to high tech. There are Greens from the Lettuce Patch Bank at the Dancing Rabbit Ecovillage in rural northeastern Missouri. In western Massachusetts one finds fine-artist-designed BerkShares, which are convertible to U.S. dollars. More than $2 million in BerkShares have been issued through the 12 branches of five local banks, according to Susan Witt, executive director of the E.F. Schumacher Society, the nonprofit behind the currency. And in South Africa, proprietary software keeps track of Community Exchange System (CES) Talents; one ambitious plan is to make Khayelitsha...
...market this decade. High-performance concrete (or ultra-high-performance, as it's known in the industry) is up to 10 times as strong as regular concrete. It costs several times as much as standard concrete, yet 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...
...High-tech concrete is just one of the products that have emerged from the research-and-development labs of cement, steel and chemicals firms this decade, and it signals an increasing commitment by heavy industry to the notion of "sustainability." As public pressure has grown to reduce energy use and carbon emissions--and in general to 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 how to lower emissions during manufacturing. But in their labs, scientists have...
...Vertical farming could allow food to be grown locally and sustainably," says Glen Kertz, CEO of Valcent, a tech company based in El Paso, Texas, that's trying out the process. His firm uses hydroponic greenhouse methods to grow upward rather than out. The result saves space--vital in urban areas--and allows farmers to irrigate and fertilize with far less waste...
