I would just add that we have invested in these demonstration projects. Industry has done the same kind of analysis that we've done, and it's not economically viable at the moment. They're not going to invest in it because they're going to do better with the open-net pen.
The only way you're going to be able to test these things.... Actually, it's not the only way, because government is not the only funder. But generally, when you're at the demonstration project level, these are usually public-private partnerships. There are a number of funding sources that contribute to these things. That is what is happening now.
