The Apparatus

Hello! For all of you guys who know, one way of winning is mining 200 kilos of this element called Neptunium. I've done some simple research over this radioactive element, and have wondered why we are mining this stuff. If you dig deeper (by deeper I mean the Subterfuge guide and forums
) you'll find that this material is used in the construction of the "Apparatus". Any thoughts on what this could be?
