Global research Technologies and Columbia university have announced the successful test of a device to extract carbon dioxide from air. The link is here .
If this works and can be made commercial, it could allow the removal of emissions from a Thai taxi in Iceland, centralising CO2 removal from the atmosphere where it could be used (for enhanced oil recovery, chemical feedstocks or putting the bubbles into Coke).
The article pointedly doesn't say anything about costs or efficiency though, so probably best not to bet the ranch just yet.
