There are some developments that are happening in the lab, looking at waterless extraction technologies, for example. You might have seen some of the work that I've been doing in looking at a waterless extraction process. We've been working on that in the lab. And I've seen some others publicized a little bit in the newspapers, and less so in the peer-reviewed journals, because I think there are a lot of issues regarding patents and what not. But there are technologies out there. Which technology is the best? We still don't have the answers.
If I can speak a little bit from personal experience, one of the challenges we've been facing with this research—and which I've also seen from other people who have been doing similar work—is that going from the lab to a pilot scale project to prove its economic potential and environmental gains is a very expensive process. We're talking several millions of dollars, and it's very high risk. So balancing the cost of that with the high risk is a difficult sell for a researcher and potentially for some of the people proposing some new innovative technologies.
Then, as I mentioned in my presentation, there's the issue that if we have such large infrastructure in place, how can we move ahead with these new technologies and leave that infrastructure in behind? I think those have been two of the challenges that I have faced, basically the risk and the associated costs of moving it into a provable—
