 We're going to have to have a set of guidances how to enter any dam. If it has to be washed before, it has to be washed before. Right now, the same dam requires 15 to 20 people to inspect. They have to call the ambulance. They have to call the fire department if something happens. So they're already waiting by. They have to have multiple personnel outside. If we can reduce that by, let's say, have four people, five people there, that's all we need. We need somebody to close the dam, the top of the dam we need.
