Mr. Egan, you said you see improvements to existing natural gas end-use technologies focusing on four specific areas of focus.
This may get to be too big a question, but I'm wondering where you see the innovation coming in industrial use, in transportation—I'm interested in that, in where the innovations are going to come in transportation, and we talked a little bit about that earlier—in renewable natural gas, and integrated community energy systems.
I wish we had more time to talk today about integrated systems. We haven't done much on that.
Where are the improvements going to come in those four areas?
