Ray nods. "I don't know how much further I can miniaturize the proton packs. They're already the miniaturization of a device that normally takes up two or three rooms in a university basement in my world. If we could render them smaller without losing the amount of shielding and structural integrity I built into them, that'd make it a heck of a lot easier to deploy the robotic solution. Of course we'd somehow have to do all this and test it in time, but still."
