The Atmospheric Carbon CapturE SystemS (ACCESS) Air-Capture System, developed by Global Research Technologies in Tucson, Ariz., holds sheets of material capable of capturing CO2 molecules directly from open air. (The chemical makeup of the fabriclike sorbent is being kept under wraps.) While that may sound tricky enough, the hard part is in prying the carbon dioxide loose once you absorb it.

To remove the molecules, the sheets are sprayed with a chemical solution that bonds to the carbon dioxide. The solution is then drained off to a separation unit, where the CO2 is isolated as pure gas through electrodialysis. A design goal was to avoid using toxic or corrosive chemicals that would require special handling, so ordinary PVC pipe is used to transfer the solution back to a collection unit so that it can be recycled.

    Wouldnt planting trees be more viable and practical than this technology ?
