Great. Thank you.
Mr. Kaufman, to move forward with carbon capture and storage, we're looking at existing infrastructure and also at new infrastructure as technology.... Well, Dr. Keith has said we already have the technology, and he's encouraged us by saying let's start cutting metal and building it.
What's the cost of building new infrastructure, as opposed to retrofitting existing infrastructure? What are the dynamics here, particularly in getting investors to invest in existing infrastructure, not in creating it?
