It has long been the holy grail for those who believe that technology can save us from catastrophic climate change: a device that can "suck" carbon dioxide (CO2) from the air, reducing the warming effect of the billions of tonnes of greenhouse gas produced each year.
Now a group of US scientists say they have made a breakthrough towards creating such a machine. Led by Klaus Lackner, a physicist at Columbia University in New York, they plan to build and demonstrate a prototype within two years that could economically capture a tonne of CO2 a day from the air, about the same per passenger as a flight from London to New York.
The prototype so-called scrubber will be small enough to fit inside a shipping container. Lackner estimates it will initially cost around £100,000 to build, but the carbon cost of making each device would be "small potatoes" compared with the amount each would capture, he said.

減碳風潮似乎在國內近三個月已經發動!
歌林冷氣的廣告最好笑:
3C商品要環保，除了使用上夠節能省電，在行銷活動上也大有綠意。歌林2008年新品充滿環保味，液晶電視及全直流變頻冷氣皆較傳統機型替消費者省下更多電費支出，並將於2008年主打「愛地球、省能源」新主張，每銷售一台全直流變頻冷氣，即替消費者在宜蘭大學所屬大礁溪實驗林場種下一棵台灣原生種小樹苗，預計在2008年種下2萬棵新苗，為減緩地球暖化盡一份心力。
減碳節能, 應該是專業技術, 不只是粗淺直覺！
