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.
又到麻省理工学院清洁能源奖的时间了。这个一年一度的竞赛给了大学生一个赢得20万美金以开始自己新清洁能源事业的机会。
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.
参加决赛的选手为天然气井设计了一种压缩技术，使得所谓边际井的生产时间比现在更长。他们说这能减少投入并增加产量。
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.
另一组发明了在分子级别上重新设计混凝土的技术，这种技术能让混凝土更坚固，而且大大减少了所耗能源。学生们说他们的技术每年节省的能源相当于100座核电站的产量。
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.
赢家是斯坦福大学的C3Nano组。他们发明了一种新材料——透明的电极，就像我们显示器和手机的屏幕那样。但我们的屏幕都很脆弱，他们的却很柔软，而且价钱是我们的十分之一。这些年轻的发明家解释道，现在在太阳电池中使用的透明电极只能吸收可利用光源的20%，而他们的材料更加透明，可以吸收更多的光。低投入高效率的方法？这可值20万美元呢。
