I’d like to see photos of each prototype individually. Curious about what would make one better than another.
Mitch McConnell doesn’t want a wall.
Modularity, ease of repair, cost, difficulty of scaling (as in climb), visibility, speed of construction... lots of ways they could differ.
Let us they need to be double walls. This way when they climb the outer wall an alarm can be triggered and we can arrest them before they finish climbing the second wall.
High sensitivity sensors at the footings to detect even deep tunnelling, ability to withstand ramming by machinery and dynamite blasts, methods that prevent scaling (embedded high pressure steam and chemical discharge nozzles that release with motion detection, built in high decibel loudspeakers (and infrasound)... and on and on.
Round top is proven design. Grappling hooks slide off and no way to grab the top
Heck, I want to know which one has those power lines attached to it in the pic that dragnet2 posted above.
Run 17Kv across the wall and they get fried trying to climb it. :D
