Cheap Photovoltaics Wins M.I.T. Clean Energy Prize
Time for M.I.T.’s Clean Energy Prize. The annual competition gives teams of university students a chance to compete for $200,000 to kick-start their new clean energy business.
又到麻省理工學院清潔能源獎的時間了。這個一年一度的競賽給了大學生一個贏得20萬美金以開始自己新清潔能源事業(yè)的機會。
One finalist designed a compression technology for natural gas wells that will allow so-called marginal wells to produce much longer than they can today. They say this will reduce costs and increase production.
參加決賽的選手為天然氣井設計了一種壓縮技術，使得所謂邊際井的生產時間比現(xiàn)在更長。他們說這能減少投入并增加產量。
Another came up with a new technique to reengineer concrete at the molecular scale––a process they say makes it stronger and uses significantly less energy. The students say their technology could save the equivalent output of 100 nuclear power plants per year.
另一組發(fā)明了在分子級別上重新設計混凝土的技術，這種技術能讓混凝土更堅固，而且大大減少了所耗能源。學生們說他們的技術每年節(jié)省的能源相當于100座核電站的產量。
And the winner? A team from Stanford called C3Nano. They’ve developed a novel material––a transparent electrode, like the screens on computer monitors and phones. But while our screens are brittle, theirs is flexible––at what they say is one tenth the price. The young inventors note that the somewhat transparent electrode used today in solar cells absorbs as much as 20 percent of available light––but theirs is significantly more transparent and will gobble up more light. Greater efficiency for less money? That’s an idea worth 200K.
贏家是斯坦福大學的C3Nano組。他們發(fā)明了一種新材料——透明的電極，就像我們顯示器和手機的屏幕那樣。但我們的屏幕都很脆弱，他們的卻很柔軟，而且價錢是我們的十分之一。這些年輕的發(fā)明家解釋道，現(xiàn)在在太陽電池中使用的透明電極只能吸收可利用光源的20%，而他們的材料更加透明，可以吸收更多的光。低投入高效率的方法？這可值20萬美元呢。
