"At the focal point of two beams, it sets up a field where molecules can't hold together anymore. Electrons can't be shared. [...]The field spreads out in a sphere, but it gets weaker the farther it spreads. Except that where it actually runs into a lot of molecules, it gets stronger and starts over. [...]Then the field dies down, the molecules come back together, and where you had ship, you now have a lump of dirt with a lot of iron molecules in it. No radioactivity, no mess. Just dirt"
