Industry is starting to take a serious look at external technologies that they are not developing themselves within their corporate structure. They like to own the technologies that they use.
Secondly, they have a certain scaling-up process. When you take a technology from an incubation stage and ramp it up to a commercial deployment stage, you have to be able to handle large volumes. That's material handling, and those are engineering design issues. You have to make those steps. That is a standard procedure, and it's very hard to circumvent that and say, “I've got it in a test tube. Now it's going to work on a 48-inch pipeline.” A lot of things can go wrong.
This is why. It's a procedure that takes time. You have to demonstrate it, prove it out, see how robust the process is, because the greater the size, the more problems can crop up.
