Are you sufficiently convinced about the maturity of the technologies that we could put a regulation in tomorrow--or at some point--that all new major carbon-emitting facilities be built, not with a facility to capture it, but capture-ready? In other words, you just set aside enough land and you make sure the pipes line up. It's a whole lot cheaper than actually putting in the rest of the system, but at least it's also a lot cheaper than having to do it later.
