Carbondioxide Catcher: New Hope in Climate Change?
Anything which gives a hope to reduce greenhouse gases is exciting!. New inventions and technologies are awaited to tackle the problem of growing greenhouse gases in the atmosphere. The recent claim on carbondioxide catcher using ion exchange resins, by a group of scientists is probably in the right direction.
The level of heat trapping carbondioxide is increasing every year and it has been recorded that its level, about 280 ppm ,before industrial revelution has now reached about 387 ppm; the figure rises about 2 ppm each year. A device that could reduce carbondioxide level in the air is thus enormously relevent. A group of US scientists claim that they have made a break through towards creating a machine called carbon scrubber that can catch greenhouse gases from the air. 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 , the Guardian reports.
"I wouldn't write across the front page that the problem is solved, but this will help," said the physicist, who hopes to have the $200,000 device operating within two years. The team's breakthrough occurred in finding a practical way to strip the CO2 from the device once it's trapped. That has long been the technological hurdle for scientists.
