6. Grapnel Gun
In Batman: The Dark Knight isnt restricted to the ground, not by a long shot, even outside of the Batwing. Youll have seen Bats use this iconic piece of gadgetry more than once in whatever youve been exposed to over the years.
In Reality: There have recently been some exciting developments in this technology that takes the grapnel gun out of fantasy and places it firmly into the realm of reality. From the good people at
Digital Force Technologies comes the T-PLS (or Tactical Pneumatic Launch System). This badboy is a pneumatically powered tactical line launcher developed for the US Army that fires a titanium grappling hook towing a 7mm Kevlar line in excess of 120 vertical feet.
Of course its massive and has about a tenth of the practicality of Batmans own Grapnel Gun but Christ, its one huge step in the right direction.
