Not all solar energy capture devices make electricity directly.
并不是所有的太陽(yáng)能吸收裝置都可以直接轉(zhuǎn)換成電能。
For example, steam generated from solar energy can turn turbines, which then produce electricity.
比如太陽(yáng)能所產(chǎn)生的水蒸汽需要轉(zhuǎn)動(dòng)渦輪進(jìn)而產(chǎn)生電能。
And, in what could be especially useful in remote regions, solar steam can desalinate water and be used in sanitation and equipment sterilization.
而且這樣的做法在偏遠(yuǎn)地區(qū)非常有效，太陽(yáng)能水蒸汽不僅可以淡化海水，還可以對(duì)環(huán)境衛(wèi)生設(shè)備進(jìn)行消毒。
Now a new technique looks to be the most efficient way yet created to use solar energy to generate steam.
而現(xiàn)在一項(xiàng)新技術(shù)是利用太陽(yáng)能產(chǎn)生水蒸汽最為有效的方法。
To absorb sunlight, M.I.T. researchers created a porous disc of graphite flakes.
為了吸收陽(yáng)光，麻省理工學(xué)院的研究人員制造了一個(gè)多孔滲水的石墨薄片圓盤(pán)。
Underneath the disk is a layer of insulating carbon foam that floats on water.
圓盤(pán)下面有一層漂浮在水面上的絕緣泡沫碳。
The foam prevents heat from being lost to the water, and has a tangle of interconnected small pores.
泡沫可以防止熱量流失到水中，也可產(chǎn)生互通的小氣孔。
As sun heats the graphite, it creates a pressure difference that pulls water up through the foam pores, like a sponge.
隨著太陽(yáng)不斷對(duì)石墨進(jìn)行加熱，就會(huì)產(chǎn)生一個(gè)壓力差，而后像擠海綿一樣，水分從泡沫孔隙中被擠壓出來(lái)。
When the water hits the graphite hot spot, it turns into steam.
當(dāng)水落在石墨的加熱點(diǎn)就會(huì)轉(zhuǎn)化成水蒸汽。
The scientists report that this inexpensive system reaches 85 percent efficiency in converting the solar energy into steam.
科學(xué)家們稱這種廉價(jià)的系統(tǒng)在轉(zhuǎn)化太陽(yáng)能為水蒸汽方面效率可以達(dá)到85%。
The study is in the journal Nature Communications.
這項(xiàng)研究已經(jīng)在《自然通訊》雜志上發(fā)表。
The researchers hope to up the efficiency further with different materials or an improved design.
研究人員希望可以通過(guò)利用不同的材料或者進(jìn)一步改進(jìn)設(shè)計(jì)增加效率。
All of which could cause steampunk fans to update their wardrobes.
所有這些都會(huì)引得蒸汽朋克粉絲去更新他們的裝備。
