New Device Vacuums Away Carbon Dioxide

A new device placed in say, Iceland, could suck up atmospheric carbon dioxide emitted from vehicles as far away as Tokyo, making it a potentially useful tool in battling ever-rising levels of this greenhouse gas.

But unlike these solutions, which reduce emissions, the new device captures carbon dioxide molecules that are already in the air and releases them as a pure carbon dioxide stream. This stream can be sequestered or used to enhance oil recovery.

“We are trapping carbon dioxide about 1,000 times faster than a tree does,” said study leader Klaus Lackner of Columbia University.

The device has an opening that pulls air in and the carbon dioxide in the air sticks to absorbent compounds (or sorbents) inside the device.

This is a very useful device.

Of course it will not be the panancea for our problems, it is definately
good to have another weapon in the battle against AICC.
