法国生化学家Pierre Calleja研发出一种街灯,能利用海藻清除空气中的二氧化碳和释出氧气.这目的为著减少二氧化碳,有人认为碳排放正是全球变暖的原因之一.
在大多数情况下,藻类在水中生长,并通过光合作用利用光能将碳转化来制造养分.研究人员正从多方面研究使用海藻作为食品、肥料、生物燃料来源,以及处理工业废水的方法.
Calleja的想法是在电灯下放置一圆柱形容器,里面装有水及藻类围绕著灯.其结果是街灯释出绿色的光,就像20世纪50年代的科幻电影场景一样,吸入二氧化碳,呼出氧气.这种灯可以放置在碳排放特高的公共区域,如街道和停车场.Calleja正与来自一家名为Fermentalg的公司的团队合作,试图研发以藻类为基础的产品,从生物燃料以至化妆品.
即使有不赞同全球暖化见解的人,设置有效的天然空气净化物这想法也有一定的说服力.另一方面,许多在技术上似乎可行及能收到效益的想法将十分昂贵.一个典型的城市很可能要数以千计这些海藻街灯,比起普通街灯建造这些灯的成本要高昂很多.虽然清洁空气的益处可节省医疗开支,但省来的与这成本相比划算吗?
再者,就是把市区的街灯都变成绿灯的美观问题.无疑,有些人会觉得美观,但其他人在黑夜里就觉得阴森恐怖.能有方法把灯光的颜色变得更暖和及明亮吗?这些问题以及其他问题的答案,将决定Calleja的想法能否现实.
原文如下：
A French biochemist named Pierre Calleja has developed a street light that also cleans carbon dioxide out of the air and produces oxygen using green algae.The idea is to reduce carbon dioxide that some thinks is a cause of global warming.
Algae exists,for the most part,in the water and feeds on light through photosynthesis and carbon.Researchers are working on a number of ways to use algae for food,fertilizer,a source of biofuel,and as a means of dealing with industrial waste water.
Calleja's idea is to take an electric light and surround it with a cylinder filled with water with algae in it.The result is a street light that gives out green light,like something on the set of a 1950s science-fiction movie,and breathes in carbon dioxide and breathes out oxygen.Such lights could be placed in public areas where carbon is heavily produced,such as streets and parking garages.Calleja is working with a team from a company called Fermentalg which is attempting to develop algae-based products from biofuels to cosmetics.
Even if one does not agree with the idea of global warming,the idea of setting up what are in effect natural air cleaners has a certain influence.On the other hand,many ideas that are technologically sound and seem to serve a useful purpose will be costly.A typical city would likely have thousands of these green algae street lights,which would cost more to build and use than ordinary lights.Will the advantages of cleaner air with the savings in health costs be worth the price?
Then there is the question of beauty concerning filling the urban air with green lights.Some will no doubt find the beauty.Others will be extremely scared in the night.Could there be some ways to make the light a warmer and brighter color?The answer to these and other questions will determine Calleja's idea can become a reality.
