Cut to the bottom of the Hudson River where some electrical “transmission lines” rest. Tony in his Iron Man supersuit has his palm-mounted repulsor rays configured such that they create a focused beam, capable of cutting through an iron pipe to reveal power cables within. Once the pipe casing is removed, he slides a circular device onto the cabling. The cuff automatically closes, screws itself tight, and expands to replace the section of casing. Dim white lights burn brighter as hospital-green rings glow brightly around the cable’s circumference. His task done, he underwater-flies away, flying up the southern tip of Manhattan to Stark Tower.
It’s quick scene that sets up the fact that they’re using Tony’s arc reactor technology to liberate Stark Tower from the electrical grid (incidentally implying that the Avengers will never locate a satellite headquarters anywhere in Florida. Sorry, Jeb.) So, since it’s a quick scene, we can just skip the details and interaction design issues, right?
Of course not. You know better from this blog.
