Trump's Mexican border wall: See the proposals

One proposal "for a wall that's covered on the southern side with solar panels, and has panels on the top that an be tilted during the day to capture the greatest amount of sunlight. Both suggest selling the electricity that the solar panels generate to offset the cost of the wall."


Here's the best plan I have seen yet for a wall yet. Doubt that Trump is farsighted enough to try something like this, but it would at least be useful rather than a total waste of money!
