Iron Man's Suit Defies Physics — Mostly

Tony Stark’s amazing suit is a long way from realization, mostly due to practical energy constraints. As a comic book fan and physics professor, I am looking forward to the big screen debut of Iron Man. This is due, in part, to the fact that instead of getting belted with gamma rays or being born a demon from hell, industrialist and scientist Tony Stark got his super powers by means of his engineering genius.

But just how realistic is Stark’s amazing suit?
