Sounds extremely promising. This machine, called a 'CO2 scrubber' is designed to suck carbon dioxide from the air. There are technical details scientist have yet to resolve - like what to do with the CO2 once it has been scrubbed from the air. The prototype will cost £100,000 and take about two years to construct. And these sorts of machines should not stop us from continuing on our quest for a greener lifestyle. Like not cutting trees and planting even more. Best CO2 scrubbers I know of :-)
A group of scientists are devising a 'CO2 scrubber’ which they claim will capture one tonne of CO2 from the air every day, about the same per passenger as a flight from London to New York, reducing the warming effect of greenhouse gases produced each year.
Although the idea has been mooted as a possible weapon in the battle against climate change, it falls far short of a quick fix solution. The 'scrubber’ devices – small enough to fit inside a shipping container – would need to be produced in their millions to soak up human carbon emissions, and the CO2 trapped would still need to be disposed of.
