Thoughts about the relationships between transport and the urban area it serves

Direct capture of CO2 from the air

I heard about this while listening to Tom Allen on CBC Radio2 this morning. Thanks to BCEN Landwatch I can give you this link to David Keith’s homepage. I did try reading his presentation which is a the top pdf document on that page, but I am afraid I need one of those really smart people who can turn science into journalism and that’s not me.

I doubt that one invention is going to allow us to continue with business as usual – but it will help with the transition. For one thing, CO2 release is only one of the problems we face. We need several more planets identical to earth if the human race is to consume resources at the same rate as North Americans (sorry Canada is as bad as the USA in that regard).

The second catch, of course, is finding somewhere to store the CO2.

While some scientists have suggested storing it deep underground or at the bottom of the ocean, it’s not yet clear how effective or affordable that would be on a large scale.
