President Donald Trump has proposed building a “solar wall” on the Mexican border that would pay for itself by generating electricity.

At a campaign rally in Cedar Rapids, Iowa.“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. Is that good?” he said.

“Think about it, the higher it goes, the more valuable it is. Pretty good imagination, right, good?” Trump said in Iowa. “My idea.”

The full year budget released in May, proposes a $1.6bn down payment for new and replacement sections of a border wall though estimated that completing the wall would cost $8bn to $12bn, though experts say the costs would run even higher.
