Charcoal - A fix for the Coal Generator

[ThatOtherGuyDupe]

So one of the most effective ways to produce energy in oxygen not included is the Coal Generator. However while an effective source of energy it is not efficient as it relies on a finite source in order to produce energy. I have an Idea that could be balanced way to keep them relevant in the later game, with an addition of charcoal. Charcoal could be produced through a module, something along the lines of some kind of oven or bio-combuster (name not yet decided), using organic materials such as algae or plants in order to make an alternative fuel source. The ways to balance this would be to make charcoal less efficient, maybe being only 2/3 or 3/4 as efficient as standard coal.
