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抯 rcenter 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.
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. Deep-sea farms are invisible 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.
1. The Hywind project uses totally new technology to ensure the stability of
.
A. the cables which tie the spar to the ocean floor

C. the blades driven by strong and steady sea wind
D. the stones filled in the spar below the sea surface
2. To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed
