"No, not joking, no,” Trump said. “There is a chance that we can do a solar wall.” He also elaborated on other feature he’d like to see: “transparency.” Literal transparency. “You have to be able to see through it,” Trump said. “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.” Because drugs, Trump explained:
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 crazy as that sounds, you need transparency through that wall. But we have some incredible designs.
