Is the Doom Plasma Rifle technically feasible, or is it just Sci-fi nonsense? In this analysis we will try to figure out the technology behind the Plasma Rifle, and how it could be implemented in the real world.

Disclaimer:
This video tries to explain the operation of a fictional weapon with real world physics. Some concepts are vastly simplified and some bold assumptions are made.
