Do All Good Ideas Come From Bad Needs-liuxiaobo

Arts-and-Entertainment In 1994 MIT researchers built their first robotic fish. However, the 2009 version is a new species. It’s made of a single, soft polymer and modeled after both bass and trout. At 5 to 18 inches long, the new robofish is much smaller, with only 10 moving parts instead of thousands. It’s able to mimic the motions of real fish, be released in oceans and costs only a few hundred dollars. Plans for these fish include mapping the ocean floor, detecting pollution, surveying submerged pipelines and surveillance. When used in groups, robofish provide a new school of thought. In 2009 Florida researchers are still using doughnuts to bait traps for black bears. However, after the bears are caught and tranquilized, they are fitted with GPS collars that use cell phone technology to text messages regarding their location every 15 minutes. To stay healthy bears need to travel to different locations and to different bear populations. As development has increased, the bears’ habitat has decreased and become fragmented by roads. The isolation causes inbreeding, which causes unhealthy bears. The GPS collars allow the researchers to know what habitat needs protecting and then land conservation decisions can be made using those "bearings". In 2009 the federal Cash for Clunkers program took 690,000 gas-guzzling cars off the road. Because only their engines had to be destroyed, everything else was available for recycling. Functioning car parts are stripped and reused in other cars. What’s left of the car becomes reincarnated into different things. For example, tires become asphalt, mud flaps or fuel. Windshields become drinking glasses, lamps or counter tops. Oil filters become cans, refrigerators or structural beams. The remaining scrap metal is melted down and could become part of another car in 30 days. It seems that recycling devours almost 100% of the "car-cus". In 2011 NASA’s new office building, "Sustainability Base", is expected to be finished. It will be the federal government’s greenest building. Costing $20.6 million, it will utilize solar panels, fuel cells and water recycling systems to power itself. A computer based on spacecraft technology will connect to local weather forecasts for environment control. It will access employees’ electronic calendars to adjust heating and cooling appropriately. Instead of air conditioning, water from geothermal wells will be piped to the building’s cooling panels. The computer will also control windows to take advantage of cool nighttime breezes. Obviously, this is cool technology. About the Author: 相关的主题文章:
