Having read the Link below, "Best/ CO2 Absorbing Plants"
I was very surprised to find this extraordinary article that was posted on the web, just a week ago
First Successful Demonstration of Carbon Dioxide Air Capture Technology Achieved by Columbia University Scientist and Private CompanyGlobal Research Technologies, LLC (GRT), a technology research and development company, and Klaus Lackner from Columbia University have achieved the successful demonstration of a bold new technology to capture carbon from the air.
*It seems to use a large Vacuum-cleaner housed in a tall tower*
A Tucson-based technology company began development of the device in 2004 and has recently successfully demonstrated its efficacy. The air extraction device, in which sorbents capture carbon dioxide molecules from free-flowing air and release those molecules as a pure stream of carbon dioxide for sequestration, has met a wide range of performance standards in the GRT research facility.
A device with an opening of one square meter can extract about 10 tons of carbon dioxide from the atmosphere each year. If a single device were to measure 10 meters by 10 meters it could extract 1,000 tons each year. On this scale, one million devices would be required to remove one billion tons of carbon dioxide from the atmosphere. According to the U.K. Treasury’s Stern Review on climate change, the world will need to reduce carbon emissions by 11 billion tons by 2025 in order to maintain a concentration of carbon dioxide at twice pre-industrial level
*I suggest you re-read that.*
The technology shows, for the first time, that carbon dioxide emissions from vehicles on the streets of Bangkok could be removed from the atmosphere by devices located in Iceland.
For example, the CO2 originating from all those vehicles in Bangkok can be captured in an oil field in Alberta, Canada, where it could be used on-site for enhanced oil recovery (EOR) operations or it could be captured in South Africa to feed a growing demand in that country for feed stocks for petrochemical production.
*Exciting, isnt it? Sounds like a fairy tale.
*Just what chemicals are they going to use to capture the CO2?
*Which itself, has to be cleaned and re-activated.
*Maybe they will use Zeolites, and dump it in the sea?
*Or some sort of thin membrain that holds CO2 back, allowing the *rest to exaust back into the atmosphere?
*Well they dont actually say - -convenient?
I guess you would need two of these Towers in every street in the World, to bring down CO2 to level it was in 1910
