Comment: "...Fixing the panels vertically could lead to an efficiency loss of around 50 percent, the analysis says, with the angle at which the sun would hit the wall losing an additional 10 percent in efficiency...this leaves the solar border wall operating at just 8 percent efficiency...."

It's become obvious that Trump is little more than a figure head in his businesses.  The guy is clueless what goes into business plans.  Additionally, he's shown no negotiation skills and no general knowledge of the basics around him like our government and even construction.  He just vomits any stupid idea that enters that head of his, then lets others around him figure it out.

That's what you get when you elect someone who's been raised with a silver spoon in their mouth.  Same garbage happened with GW Bush.
