　　Not all solar energy capture devices make electricitydirectly.

　　并不是所有的太阳能吸收装置都可以直接转换成电能。

　　For example, steam generated from solar energy canturn turbines, which then produce electricity.

　　比如太阳能所产生的水蒸汽需要转动涡轮进而产生电能。

　　And, in what could be especially useful in remoteregions, solar steam can desalinate water and be used in sanitation and equipmentsterilization.

　　而且这样的做法在偏远地区非常有效，太阳能水蒸汽不仅可以淡化海水，还可以对环境卫生设备进行消毒。

　　Now a new technique looks to be the most efficient way yet created to use solar energy togenerate steam.

　　而现在一项新技术是利用太阳能产生水蒸汽最为有效的方法。

　　To absorb sunlight, M.I.T. researchers created a porous disc of graphite flakes.

　　为了吸收阳光，麻省理工学院的研究人员制造了一个多孔渗水的石墨薄片圆盘。

　　Underneath the disk is a layer of insulating carbon foam that floats on water.

　　圆盘下面有一层漂浮在水面上的绝缘泡沫碳。

　　The foam prevents heat from being lost to the water, and has a tangle of interconnected smallpores.

　　泡沫可以防止热量流失到水中，也可产生互通的小气孔。

　　As sun heats the graphite, it creates a pressure difference that pulls water up through thefoam pores, like a sponge.

　　随着太阳不断对石墨进行加热，就会产生一个压力差，而后像挤海绵一样，水分从泡沫孔隙中被挤压出来。

　　When the water hits the graphite hot spot, it turns into steam.

　　当水落在石墨的加热点就会转化成水蒸汽。

　　The scientists report that this inexpensive system reaches 85 percent efficiency in convertingthe solar energy into steam.

　　科学家们称这种廉价的系统在转化太阳能为水蒸汽方面效率可以达到85%。

　　The study is in the journal Nature Communications.

　　这项研究已经在《自然通讯》杂志上发表。

　　The researchers hope to up the efficiency further with different materials or an improveddesign.

　　研究人员希望可以通过利用不同的材料或者进一步改进设计增加效率。

　　All of which could cause steampunk fans to update their wardrobes.

　　所有这些都会引得蒸汽朋克粉丝去更新他们的装备。

　　词语解释

　　1.pull up 拔起;停下来

　　The tornado pulled up the old tree by its roots.

　　龙卷风把那根古树连根拔起。

　　The policeman pulled up the motorist and asked tosee his licence.

　　警察让那个开车的人停下来，要求看他的执照。

　　2.convert into 使转变;把…转化成

　　These investors seem simply to be agreeing to convert into the next round no matter what theterms of the next round are.

　　这些人基本都同意转换为下一轮融资的股权，不管下一轮融资的条款怎么样。

　　That gives it the opportunity to absorb, and thus convert into electricity, most of the redlight falling on it, as well as the blue.

　　这使得它有机 会将大部分照在它上面的红光光线以及蓝光光线吸收并且转换成电能。
