Stealth on the Water

   Posted by: admin

An undercover team of navy seal is not worth much if their transport boat’s wake betrays their approach. Nor  does it help if they come ashore with the back pain and possible organ damage from the boats constant bouncing. A sleek new hull design could help troops slip through waves undetected and unscathed, while also setting a new standard for efficient nautical design. While experimenting with high speed yacht designs for the america cup sailing race, aerospace engineer began investigating ways to reduce the wake that builds around the vessel’s bow. Sides and stern as it cruises through water and draining fuel. The bow of concept, called the transonic hull, is shaped like a tight v and cuts through water like a knife, diverting the wake sideways and under the boat to nearly eliminate it all together. Preliminary tests of a 20 foot wood and fiberglass prototype indicate that the model incurs 28 to 38 percent less drag than an ultra streamlined, which says could translate to 30 percent better fuel economy than similar boats. And it powered through waves four fell tall without bouncing.

The design is still unproven. The early results look promissing, but worries that the hull’s efficiently might not translate well to slow speeds. People focused on the right part of the boat to make real progress in reducing bow wake, but adds that he needs to see more test data and computer simulations to vouch for the concept.

Up on the Farm

   Posted by: admin

Point your cursor to any corner of the Interest specializing in speculations on the future of architecture and design, and you will likely stumble upon boards of highly developed and intricately rendered schemes for vertical farming. Not unlike the way in which tart frozen yougurt, cupcakes, pork belly, and mobile eateries have all become unlikely culinary phenomena, vertical farms appear to have usurped the collective consciousness of imaginative designers everywhere. Leaving aside the questions of who would own and be responsible for the the thins, they’re an attractive solution to a number of issues, food supply and demand, sustainable farming practices, water and energy consumption, and shipping costs among them. As more of us find ourselves living in metropolices, where our food will come from and who will produce it become ever more pressing questions. These vertical farms, multi story urban sites with crops and vegetables growing in green house like conditions in their levels and livestock and fish thriving below could conceivably alleviate many of those issues.

Through today’s vertical farms may well go the way of yesterday’s walking cities, there are a number of promising developments that point to a symbiosis of urbanism and agriculture. Look no further than new york city, of all places. There you’ll find what is perhaps the most exciting and improbable design achievement of the last decade, the high line, a decommissioned elevated railway on Manhattan’s west side that was transformed into a public park.
