[Terrapreta] Ice-age anyone? - RWL part 2.

[Greg and April]

Hmmm.....

I have heard of this technology, but I always end up wondering just how effective and truly long lasting it is.

I may not agree with the theory of AGW, but if CO2 is the issue, I can't help but wonder about the 2 oxygen atoms attached to that carbon atom - they had to have come from somewhere, and the supply is not infinite.

  Just plain compressed CO2 Greg. It's not my gig, but there has been quite a lot of R&D here in Alberta to evaluate the likelihood it will stay underground. Bill Gunter at Alberta Research Council is one of the researchers taking a lead on this should you wish to do some Googling.



  Some of it is to be used to help recover more oil. I was actually peripherally involved in that aspect of it some 40 years ago. I understand most is simply to be pumped underground to keep it out of the atmosphere. That's why I comment I'm glad to see a potential use for it as suggested by Peter Read.



  Personally, I have a feeling that using it to produce char and build up the soil might be more beneficial.



  Sincerely,



  Duane Pendergast

  What form is that CO2 going to be in when pumped underground, and what make you sure it's going to stay there?

              Good points Peter. It's good to see someone has identified a positive use for that CO2 we Canadians are preparing to pump underground at great expense.
