Thank you.
This is a question for Mr. Bush and Mr. Doyle.
In your last response to Mr. Fisher you started getting into the details of what your technology actually does. Mr. Bush, you didn't get into the biogas part of it. I won't get you to expand too much on that. Tell us a little bit about the challenge you had. You actually have implemented this technology in the United States in a very large dairy operation. How did that go? Why did you go to the United States?
