Well, some olivine dust has caused a little storm, happy to see that it is taken seriously. Some people are asking questions for which some answers are contained in the paper that I sent you a few days ago. (A natural strategy against climate change). Several of the other questions I recognize, but are beyond my capacities to answer, any help is welcome. One fact is clear, fortunately. The Earth’s mantle is almost completely composed of olivine, thanks to plate tectonics, we won’t have to mine it at 30 km depth. Huge slabs have been pushed up, and are now at the surface, often with a thin cover of their own weathering crust, so there is more available than we will ever need to solve the problems of climate change and ocean acidification. I am not implying that we shouldn’t use other solutions as well. I am happy to see that you all realize that the huge CO2 problem cannot be solved with a teaspoon of some miracle stuff, Olaf Schuiling
From: [email protected] [mailto:[email protected]] On Behalf Of Bill Stahl Sent: maandag 26 januari 2015 23:15 To: [email protected] Subject: [geo] Re: Energy Planning and Decarbonization Technology | The Energy Collective I hesitate to add to what is already a leviathan of a thread... but here goes. Assuming a carbon price were in effect, could coastal governments and landowners offset the cost of beach enhancement & sand replacement with CO2-sequestering sand? It would not have to optimally efficient to be substantial. On the face of it, getting permitted to use olivine on beaches seems a huge hurdle, but there is a already a tremendous amount of stirring-up of shallow coastal waters, budgeted and permitted. Transportation has already been arranged. Based on my familiarity of the Jersey Shore, coastal towns throw enough money at replacing sand that will quickly erode away, so why not put it to some long-term use? (Perhaps Atlantic City's unemployed croupiers can be sent out stirring the beaches). I have no idea how to calculate the potential scale, but perhaps this has already been done. Convince homeowners' associations to link CDR to property values and you've harnessed an unstoppable force... And is dredging relevant here?
