List: 1. I thought this list had a very useful dialog a few months ago on the CDR technology called Direct Air Capture (DAC - sometimes "Artificial Trees"). I have just become aware of an invitation-only meeting on this topic - hosted by the group "ISEEE" at the University of Calgary on March 6 and 7. A preliminary agenda is available at: http://www.iseee.ca/dacs/
2. Two useful recent descriptions of the dialog are given at: http://www.economist.com/node/21550241 and http://www.marcgunther.com/2012/03/11/direct-air-capture-of-co2-is-becoming-a-business-for-better-or-worse/ 3. Marc Gunther also had an article on the major DAC companies just as the meeting was starting at: http://chimalaya.org/2012/03/06/rethinking-carbon-dioxide-from-a-pollutant-to-an-asset/ 4. I gather from this material that Prof. Socolow was under considerable pressure to lower his (and APS') decidedly negative projection on costs. I wonder if any list member in attendance can comment on this controversy - that was covered nicely on this list. 5. I also gather there was considerable unhappiness in the present emphasis of all (?) of these DAC companies away from CDR - and instead on to uses of the captured CO2 for enhanced oil/gas production and for combination with H2 for appreciably lower carbon footprint fuel production. Any comments on these aspects - or any other part of the meeting? Thanks in advance for any additional information.
