Short answer is that it happens naturally in snow covered serpentinite mine tailings, so they're trying to figure out how to enhance/ speed the mechanisms and apply it to the world.<BR/><BR/>Have you considered getting the head geo for the local coal bed project to come in and give a seminar? Could do the same for the sequestration pilot folks, if they're in the close corner of AZ.C W Mageehttps://www.blogger.com/profile/09706100504739548720noreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-87127140326073370492008-11-10T13:55:00.000-08:002008-11-10T13:55:00.000-08:00I commented on this back in July- I am, as I said ...<A HREF="http://outsidetheinterzone.blogspot.com/2008/07/dont-pass-gas.html" REL="nofollow">I commented on this</A> back in July- I am, as I said in the post, uncomfortable with simply shoving the gas underground and expecting it to stay put. The appealing thing about basalt sequestration is that stable minerals would form. I'm not really advocating that approach- I don't know enough, for example, about the dynamics of the process. How long would it take to decompose the silicates and tie up the CO2? I do think it's worthy of further study.Lockwoodhttps://www.blogger.com/profile/05960762797349483760noreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-78082568953512101342008-11-09T20:58:00.000-08:002008-11-09T20:58:00.000-08:00Google must have seen your question coming - they ...Google must have seen your question coming - they just recently posted a Google Tech Talk titled, "Carbon Dioxide Capture and Sequestration: Hype or Hope?" (<A HREF="http://www.youtube.com/watch?v=Qw4iJmzSywA" REL="nofollow">http://www.youtube.com/watch?v=Qw4iJmzSywA</A>). I watched it and found it relevant and educational. It's primarily concerned with existing technologies for carbon sequestration and gives some good detail of the geologic requirements/considerations. If memory serves me there was mention made of another upcoming talk on the same general subject; no idea when or if that will be published, too.<BR/><BR/>There have also been a couple of recent news releases/blog posts about carbon sequestration by weathering of peridotite (<A HREF="http://www.eurekalert.org/pub_releases/2008-11/teia-rc110508.php" REL="nofollow">http://www.eurekalert.org/pub_releases/2008-11/teia-rc110508.php</A>). Much less practical at the moment, but an interesting pathway for future development.Ron Schotthttps://www.blogger.com/profile/10020094512548523216noreply@blogger.comtag:blogger.com,1999:blog-7563205518828267408.post-81271847622947657232008-11-09T20:56:00.000-08:002008-11-09T20:56:00.000-08:00This comment has been removed by the author.Ron Schotthttps://www.blogger.com/profile/10020094512548523216noreply@blogger.com
