Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle-named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon. Terrafugia公司星期一说,它的新飞车已经完成了首次飞行,公司明年销售飞车的目标更近了。这款名为Transition的汽车有两个座位、四个车轮和可折叠的翼子板,这样它就可以像汽车一样驾驶了。上个月在1400英尺的高空飞行了8分钟,在公路上的时速可达70英里,在空中的时速可达115英里。它使用23加仑的油箱飞行,每小时在空中燃烧5加仑。在地面上,每加仑汽油可以行驶35英里。 Around 100 people have already put down a 279, it won’t help if you’re stuck in traffic. The car needs a runway. 大约有100人已经存了1万美元的定金,以便在上市时获得过渡,而在本周晚些时候的纽约车展上Terrafugia向公众介绍Transition后,这一数字可能会上升。但别指望它会出现在太多车道上。预计花费万美元,如果堵车也没用。这辆车需要一条跑道。 Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The govemment has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards. 航空业专家罗伯特•曼恩表示,发明家们从上世纪30年代就开始尝试制造飞行汽车。但是曼恩认为Terrafugia比任何都更接近于让飞行汽车成为现实。政府已经允许该公司使用特殊材料,以使车辆更容易飞行。目前,Transition正在进行碰撞测试,以确保符合联邦安全标准。 Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find redatively easy to meet. 曼恩说,五年前联邦航空管理局决定为轻型运动飞机制定一套单独的标准,这一标准比大型飞机的飞行员要低,这对Terrafugia来说是一个帮助。Terrafugia说,飞机员需要通过测试,完成20小时的飞行时间,才能驾驶Transition,飞行员会发现这一要求很容易满足。

A build-it-yourself solar still is one of the best ways to obtain drinking water in areas where the liquid is not readily available.Developed by two doctors in the . Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5'×5' sheet of clear or slightly milky plastic, six feet of plastic tube, and a container-perhaps just a drinking cup-to catch the water. These pieces can be folded into a neat little pack and fastened on your belt. 自行建造太阳能蒸馏器是在很难获得水的地区获取饮用水的最佳方法之一。这是一种出色的集水器,由美国农业部的两位博士研制。不好的是,你必须随身携带必要的设备,因为几乎不可能找到天然替代品。尽管需要的配件是一块5’×5’的透明或淡乳色塑料片、6英尺长的塑料管和一个容器(可能只是一个用来盛水的杯子)。这些配件可以折叠成整洁的小包装,系在腰带上。 To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up-and out-the side of the hole. 要建造蒸馏器,可以用锋利的木棍或石块挖一个四英尺宽、三英尺深的洞穴。在潮湿的地方挖洞,可以提高集水器的工作效率。将杯子放置在洞穴最深处,然后将管子放好,一头完全放入杯中,其余部分从洞穴中伸出。 Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's center down with a rock. The plastic should now form a cone with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup. 接下来,用塑料片盖住洞穴,用泥土固定塑料片边缘,并用石块压住塑料板中心。塑料片现在应该会形成一个45度角边的圆锥体。塑料片的低点必须位于杯子正上方中心位置,且不高于杯子上方三英寸。 The solar still works by creating a greenhouse under the plastic. Ground water evaporates and collects on the sheet until small drops of water form, run down the material, and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink. 在塑料片下方形成一个温室,太阳能蒸馏器就开始工作了。地下水蒸发并聚集在塑料片上,直至形成小水滴,顺着材料流下来,落入杯中。当容器装满时,可以通过管子吸出淡水,不必每次需要喝水时都要拆除蒸馏器。
