The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical Power Research Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States’ power grid from lightning strikes. ‘We can cause the lightning to strike where we want it to using rockets’: says Ralph Bernstein, manager of lightning projects at EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.

  2. voltage noun [ C or U ] UK /ˈvɒl.tɪdʒ/ US /ˈvoʊl.t̬ɪdʒ/ the force of an electric current, measured in volts电压;伏特数
    high/low voltages 高/低电压
  3. bear up — phrasal verb with bear UK /beər/ US /ber/ verb bore, borne or us also born
    to deal with a very sad or difficult situation in a brave and determined way勇敢地支撑下去,咬紧牙关坚持
    “How has she been since the funeral?” “Oh, she’s bearing up.”“葬礼以后她怎么样了?”“哦,她一直在挺着。”

Bad behaviour
But while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1,200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. ‘Lightning is not perfectly well behaved: says Bernstein. ‘Occasionally, it will take a branch分支 and go someplace it wasn’t supposed to go.’

And anyway, who would want to fire streams of rockets in a populated area? ‘What goes up must come down,’ points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed支持 by EPRI, to try to use lasers to discharge lightning safely — and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500,000 invested so far, a promising system is just emerging from the laboratory.

  1.  a populated area;人口稠密的地区

The idea began some 20 years ago, when high-powered lasers were revealing their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionisation电离 in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge. To stop the laser itself being struck击中, it would not be pointed straight at the clouds. Instead, it would be directed at a mirror, and from there into the sky. The mirror would be protected by placing lightning conductors避雷针 close by. Ideally, the cloud-zapper (gun) would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.

  1. brew verb (BAD SITUATION) [ I ] If an unpleasant situation or a storm is brewing, you feel that it is about to happen.(坏事或暴风雨)即将来临,酝酿

  4. ion noun [ C ] UK /ˈaɪ.ɒn/ US /ˈaɪ.ɑːn/ specialized离子
  5. electron noun [ C ] UK /iˈlek.trɒn/ US /iˈlek.trɑːn/
    an extremely small piece of matter with a negative electrical charge电子
  6. ionization  noun [ U ] uk usually ionisation UK /ˌaɪ.ə.naɪˈzeɪ.ʃən/ US /ˌaɪ.ə.nəˈzeɪ.ʃən/电离

    a sudden increase of an emotion(情感的)涌起,翻涌

A stumbling block绊脚石
However, there is still a big stumbling block. The laser is no nifty portable: it’s a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.

  1. in the offing: likely to happen soon即将来临的;即将发生的
    With an election in the offing, the prime minister is keen to maintain his popularity.选举在即,首相非常注意保持其声望。
  2. nifty adjective UK /ˈnɪf.ti/ US /ˈnɪf.ti/ informal,  good, pleasing, or effective绝妙的;有吸引力的;利落的

  3. stumble verb UK /ˈstʌm.bəl/ US /ˈstʌm.bəl/         stumble verb (WALK)C2 [ I ] to step awkwardly while walking or running and fall or begin to fall绊脚;绊倒。   Running along the beach, she stumbled on a log and fell on the sand.她沿着海滩跑步时绊到一块木头上摔倒了。In the final straight Meyers stumbled, and although he didn’t fall it was enough to lose him first place.迈耶斯在最后的直道绊了一下,虽然没有摔倒,但也足以使他丢掉第一的位置。[ I usually + adv/prep ] to walk in a way that does not seem controlled跌跌撞撞地走,蹒跚而行

    When the poet stumbled over a line in the middle of a poem, someone in the audience corrected him.诗人在朗诵一首诗的过程中念错了一句,听众中有人纠正了他。

Bernstein says that Diels’s system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. `I cannot say I have money yet, but I’m working on it,’ says Bernstein. He reckons that the forthcoming field tests will be the turning point — and he’s hoping for good news. Bernstein predicts `an avalanche of interest and support’ if all goes well. He expects to see cloud-zappers eventually costing $50,000 to $100,000 each.

  1. reckon verb UK /ˈrek.ən/ US /ˈrek.ən/

    We were swamped by an avalanche of letters/phone calls/complaints.大批的来信/电话/投诉让我们疲于应付。

Other scientists could also benefit. With a lightning `switch’ at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of `interactive meteorology‘ — not just forecasting the weather but controlling it. `If we could discharge clouds, we might affect the weather,’ he says.

    Some scientists believe that there is about ten times as much matter in the universe as astronomers have observed.有些科学家认为,宇宙中的物质约有天文学家所观测到的10倍之多。

And perhaps, says Diels, we’ll be able to confront some other meteorological menaces. `We think we could prevent hail by inducing诱发 lightning,’ he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones冰雹 that threaten crops. With luck, as the storm clouds gather this winter, laser-toting researchers could, for the first time, strike back.

  1. moist adj. 潮湿的—-moisten v. /ˈmɔɪ.sən/ 弄湿,沾湿;(使)变潮湿—- moisture
