  • Oil and water don't mix.
  • 油与水不能混合。
  • Despite that age-old axiom, it sure is hard to get spilled petroleum out of seawater, as was evident during BP's blowout in the Gulf of Mexico.
  • 尽管有这样古老的公理,也很难将泄漏的石油从海水中弄出来,而且英国石油公司在墨西哥湾一事确是证明了这一点。
  • But what if you could make oil magnetic?
  • 但是如果你能让石油变得磁化会怎样呢?
  • That thought came to physicist Arden Warner while he watched coverage of the spill back in 2010.
  • 这个想法来自于物理学家雅顿华纳,他是在2010年看过有关泄漏的报道后迸发出这样的灵感。
  • And it launched some garage tinkering for Warner,
  • 华纳晚上在车库中致力于自己的奇思妙想研究。
  • who by day works on improving particle accelerators at Fermilab.
  • 于是白天在费米实验室进行粒子加速器的改进工作后,
  • He shaved iron bits from a shovel and sprinkled them atop some engine oil.
  • 他将铲子上的铁去除,在顶部撒上一些机油。
  • Lo and behold, a refrigerator magnet pulled the blob of oil wherever he wanted.
  • 你瞧, 无论他去到那里,冰箱磁铁都可以将油滴剥离。
  • Now he's got a patent on the concept that he's refined over the past few years.
  • 现在经过几年的改善他获得了这一理念的专利。
  • The Warner method requires only a relatively small amount of magnetic metal dust.
  • 华纳的这种方法只需要相对少量的磁性金属粉末。
  • And the iron particles mix better with oil than with water, or with anything else the oil might get on,
  • 而铁颗粒与油水相比混合,或者同其它石油可能的附着物,
  • like bird feathers or plants.
  • 比如鸟的羽毛或植物等效果更好。
  • Another plus: once the oil is collected, the filings can be dried off and reused.
  • 另一个好处是:一旦石油被收集起来,这些碎末可以变干并且再次循环利用。
  • And iron is more environmentally friendly than the chemicals currently used to disperse oil.
  • 而且铁比目前在分散石油方面使用的化学品更为环保。
  • So maybe next time there's an oil spill-
  • 也许下次的石油泄露,
  • and fortunately there will be a next time-we can clean up the mess with magnets.
  • 肯定会有下一次,可以使用磁铁收拾残局。
