All the proposals envisage a giant pipe starting with a coal plant, but then collecting carbon dioxide from anyone who will capture it before bringing it out to be buried under the sea bed.

BBC: Carbon dioxide from industry could be buried offshore

Sorry, I'll tune in again at bed time, but right now I've just got to hand-sharpen my new Japanese carbon-steel knife and mince shallots for the red-wine reduction sauce I'm slathering on those dry-aged rib-eyes that I got from Joe the Butcher, my new best friend.
