Donald Trump has suggested his proposed wall on the US-Mexico border could be made cheaper by attaching solar panels to it.
Addressing a rally in Iowa, the US President said the panels would provide cheap energy and help to pay for the controversial project, which he used as a rallying point against illegal immigration and drug smuggling in his election campaign.
Although he suggested the plan was his own, saying: “Pretty good imagination, right? My idea”, a number of designs for the wall submitted by companies have reportedly featured solar panels.
President Trump has said he would make Mexico foot the bill for the wall, an idea the Mexican President has dismissed.
He said: “We’re thinking of something that’s unique, we’re talking about the southern border, lots of sun, lots of heat.
“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?”
He also suggested the higher the wall goes, the more solar panels it could accommodate and so be more profitable.
The Trump Administration has been accused of violating the law by not publishing energy efficiency standards.
