Mr. Stark’s reactor. Mr. Stark had fought hard to wire the clean energy into New York’s electrical grid, and the reactor under Stark Tower powered hundreds (if not thousands) of buildings around the city. It was supposed to last upwards of a hundred years, even with the strain on it, and, along with preventing power surges and being immune to blackouts, be virtually indestructible. You needed to sedate me with that fic! DVD commentary?
Aha I really loved that fic! I wanted something that reminded people that Spider-Man is, canonically, the strongest Marvel superhero to exist, but also I love Peter Parker having adorable hero-worship for Mr. Stark, so of course Peter would know almost everything there is to know about what Tony does and how hard he fought to do it, especially with the arc reactor which is goddamn revolutionary. Overall, I think it turned out really well, although no one questioned the end of the story which I was kinda disappointed about. I included some easter eggs just to make myself happy but no one seemed to pick up on it.
