Cars and electric powerplants release billions of tons of carbon dioxide or CO2 into the air every year. The amounts of this colorless, odorless gas have been increasing and contributing to Global warming Unusual amounts of CO2 have been collecting in the atmosphere for a long time. Now, CO2 acts like a huge invisible blanket, trapping the sun’s heat so that the earth’s climate gets warmer and levels of CO2 in the air may double in the years ahead. About half of the carbon dioxide pollution comes from the smokestacks of electric powerplants that burn coal. Scientists are working hard on technology that can capture and store that CO2 before it gets into the air. Unfortunately, there is no good way of catching CO2 that’s already in the air from other sources including the tailpipes of cars and trucks. Once CO2 gets into the air, it spreads out like a drop of food coloring in a swimming pool full of water. If you removed all the CO2 from the air inside a huge railroad box car for instance, you’d wind up with only 2 ounces of CO2. A New York Scientist, Dr Frank Zamond may have a solution to this big problem. Dr Zamond’s machine sucks up carbon dioxide that’s spread out in the air around us. His so-called “air capture systems” could be installed anywhere outdoors trapping excess CO2 from cars, forest fires and other sources like a big vacuum cleaner! Dr Zamond figured out a way of using natural draughts, or air currents, to bring gigantic amounts of air into the machine without using a lot of energy. By spreading these machines all over the planet, Zamond’s Carbon Vacuum could be an enormous help at lowering the earth’s carbon dioxide levels. For our warming planet, this could be very cool news indeed! ☺ Cécile Canu - Emilangues 2010 2 New vocabulary and expressions English To slurp up damage worlwide Electric powerplants billions Global warming Have been collecting in the atmosphere..
