According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see pic-ture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.
The project, called Hywind, is the world's first large-scale deep-water 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 be fixed 213 feet above the water on a floating spar (鄉 picture )，a technology Hywind's creator, the Norwegian company Statoil Hydro , 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）；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind's 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 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 it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar's centre of gravity must be moved much closer to the ocean's 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 benefits 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. Deepsea farms are in-visible from land, which helps overcome the windmill-as -eyesore objection. If the technology catches on, it will open up vast areas of the planet，s surface to one of the best low-carbon power sources available.
The Hywind project uses totally new technology to ensure the stability of __________.

To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting __________
