Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An exp

2、eriment under way off the coast of Norway, however, could help put them anywhere. The project, called Hywind, is the worlds first large-scale deepwater wind turbine (涡轮发电机). Although it uses a fairly standard 152-ton, 2. 3-megawatt turbine, Hywind represents totally new technology. The turbine will

3、be fixed 213 feet above the water on a floating spar(see picture), a technology Hywinds creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables (缆索); thes

4、e will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywinds stability (稳定性) in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity

5、six miles off the coast of southwestern Norway as early as September. To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but its difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To

6、make that turbine heavier, the whole spars centre of gravity must be moved much closer to the oceans surface. To do that, the company plans to design a new kind of wind turbine, one whose gearbox (变速箱) sits at sea level rather than behind the blades (see picture). Hywind is a test run, but the benef

7、its for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If th

8、e technology catches on, it will open up vast areas of the planets surface to one of the best low-carbon power sources available. 1. The Hywind project uses totally new technology to ensure the stability of.A. the cables which tie the spar to the ocean floorB. the spar which is floating in deep-sea

To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting.A. on the sea floorB. on the spar topC. at sea level D. behind the bla

The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot

21、(赤脚). Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot.
