I'll just comment on water, because I'd like to use a marketing ploy, if I could.
I was out at our lab in Devon, Alberta, the other day. Some of you may know that, traditionally, to produce one barrel of bitumen out of the oil sands, you have to use five gallons of water. We have a lab in Devon that has been working with industry. It used to be four to five gallons, and we now have it down from four gallons to three. So we've significantly reduced the use of water already. They're now working on trying to reduce it by another factor of 20%.
I think the bottom line is that the basic science is there, but the way to make it operational is what's going to take some time.
But the marketing effort I wanted to make with you and the chair is that, as you move to understand the department, I would really urge you to visit some of our labs. They will give you a very practical understanding, and if you do that, being able to talk with our stakeholders on whether we're doing a good thing or a bad thing might help the deliberations of the committee.
On water, for example, some efforts have been made. We have had results, and we need to do some more.
I wonder if I can defer to either Mr. Brown or Ms. Buckley.
