We're thinking about building the wall as a solar wall, so it creates energy, and pays for itself. And this way Mexico will have to pay much less money, and that's good, right, is that good? You're the first group I've told that to, a solar wall, makes sense, let's see, we're working it out, we'll see, solar wall, panels, beautiful.
