Climb any wall with big vacuum-powered suction cups
Engineers at Utah State University recently won a contest put on by the Air Force, which asked people to invent a way for soldiers to get over tall walls.
From Oh Gizmo…
They developed what they call a PVAC, or Personal Vacuum Assisted Climber and it works just as you’d imagine: a loud-as-hell vacuum strapped to your back connects to two suction cups and lets you climb pretty much anything, even if the surface wouldn’t have been so good for regular suctions cups.
It’s loud, and heavy, and it’s still in the development stages, but the work they’ve done so far is impressive enough that the Air Force coughed up $100,000 to let them keep working on it.
