I'm coming to that. I'm sorry, I just wanted to set that straight first.
We have been working in this area for maybe twelve years or so. You have visited the oil sands and seen how large they are. It is very difficult to move all that huge machinery. So we have worked with the industry since that time to convince them to try new technologies. They started with this consortium. They started implementing consolidated tailings, adding some gypsum and so on to it to make it more trafficable and get the water out quickly. Suncor started using it in one or two applications. They had to give it a couple of years before they could evaluate the results to see if it works or not. Actually, in this case it works very well. There were some problems, but they worked on the problems. Syncrude had started doing that also. So this was one technology.
But since then we've come up with two or three technologies, and one of them is, I would say, close to commercialization. It is in the field now. It's called dry stackable tailings. But dry is a misnomer. It's not really dry; it still has about 15% water in it. But you can drive a Caterpillar and things like that on it, which is the criterion for that.
So we have been working with them for quite a while. We have been publishing for quite a while, because this is the influence we have. We can influence what's going on by publishing in the general--
