Question: You were joking about solar, right?
Trump: No, not joking, no. There is a chance that we can do a solar wall. We have major companies looking at that. Look, there's no better place for solar than the Mexico border -- the southern border. And there is a very good chance we can do a solar wall, which would actually look good. But there is a very good chance we could do a solar wall.
One of the things with the wall is you need transparency. You have to be able to see through it. In other words, if you can't see through that wall — so it could be a steel wall with openings, but you have to have openings because you have to see what's on the other side of the wall.
And I'll give you an example. As horrible as it sounds, when they throw the large sacks of drugs over, and if you have people on the other side of the wall, you don't see them -- they hit you on the head with 60 pounds of stuff? It's over. As cray as that sounds, you need transparency through that wall. But we have some incredible designs.
