The chemical extractor is a machine that is used to 1. obtain a fissle fuel rod or 2. deuterium. This machine requires power, and an infinite battery will not work. It can be connected to mechanical pipes or liquiducts to obtain water. In order to make deuterium, you must place a battery in the energy slot, an empty cell in the top left slot, and the extractor will make deuterium. To make a fission fissle rod, the uranite goes in the left slot, and the yellowcake (which is made by pulverizing uranium) goes in the next right slot. The battery goes in the energy slot, and the extractor will make the fuel rod to power the fission reactor.
