AccordingtotheUSgovernment, windfarmsoffthePacificcoast could produce 900 gigawatts of electricity every year. Unfortunately,thewater there is far too deep for eventhetallest windmills (see picture)totouch bottom. An experiment under way offthecoast of Norway, however, could help put them anywhere.
Theproject, called Hywind, istheworld's 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.Theturbine will be fixed 213 feet abovethewater on a floating spar (see picture), a technology Hywind's creator,theNorwegian company StatoilHydro, has developed recently.Thesteel spar, which is filled with stones and goes 328 feet belowthesea surface, will be tiedtotheocean floor by? three cable (缆索); these will keepthespar stable and preventtheturbine from moving up and down inthewaves. Hywind's stability (稳定性) inthecold and rough sea would prove that eventhedeepest corners oftheocean are suitable for wind power. If all goesaccordingtoplan,theturbine will start producing electricity six miles offthecoast of southwestern Norway as early as September.
Toproduce electricity on a large scale, a commercial wind farm will havetouse bigger turbines than Hywind does, but it's difficult enoughtobalance such a large turbine so high on a floating spar inthemiddle oftheocean.Tomake that turbine heavier,thewhole spar's centre of gravity must be moved much closertotheocean's surface.Todo that,thecompany planstodesign a new kind of wind turbine, one whose gearbox (变速箱) sits at sea level rather than behindtheblades (see picture).
Hywind is a test run, butthebenefits for perfecting floating wind-farm technology could be extremely large. Out at sea,thewind is often stronger and steadier than closetoshore, where all existing offshore windmills are planted. Deep-seafarmsare invisible from land, which helps overcomethewindmill-as-eyesore objection. Ifthetechnology catches on, it will open up vast areas oftheplanet's surfacetoone ofthebest low-carbon power sources available.
