Does the arc reactor have infinite energy or what? How does it work?

Imagine fallout universe discover arc reactor tech.

@Abdalla1234 my understanding is the upgraded version of the arc reactor is based on tesseract energy. Which he does make after finding out the blueprint in the model of stark expo.

Either way, if the arc reactor is applied everywhere it does look like it will save us some trouble.

@LimittlesRealm they discovered cold fusion, which is similar.

But it's very oversized.
