You take beam of electrons (in your accelerator) and shoot it through an area of alternating magnetic fields literally called a wiggler field (or an undulator field if you're boring). All that scene in Iron Man 2 needed was a bit more technobabble about how he figured out how he can stabilize the nucleus using a Casimir quark suspensor field or some other crap like that.Īctually Free Electron Lasers are created using particle accelerators, and they're fucking awesome. One of those has enough random technobabble that I'm perfectly happy to accept it, the other is cringeworthy wrongness. "I'm going to travel backwards in time by pushing the Earth so it rotates backwards" "I'm going to travel backwards in time using a hyper-Newtonian supermagnetic Kwizacch-field generator", and You're not going to enjoy Iron Man if you're saying "but hooooww do arc reactors and repulsor jets work?"īut this scene in Iron Man 2 bugged me, I guess because he was doing real things using vaguely real-looking technology, in a way that just doesn't work.

On one hand, you're an idiot if you can't just sit there and accept "Look, it's science fiction, it has to work for the sake of the plot, it's fictional technology, get over it, let's move on".
