I would say that's a difficult question to answer, because when we do research and development, it's just that, research and development, and all of those things that are tested in the lab and work in the lab might not work when we go up to pilot scale. For example, there are technologies that really work well in the lab, but to scale them up poses a whole host of new challenges.
So I don't think we're investing dollars that aren't going to bear fruit. Eventually, there might be some other innovation that comes out of that, but there are some technologies.... I guess we feel, my collaborators and I on this project, that there seems to be a chasm that makes going from that basic small pilot scale to the large pilot scale a very difficult leap. We found there has been a little bit of movement with private and venture capitalists, if you will, or angel investors. Those seem to be the people who are willing to take a little bit more of a risk.
