I feel like usually mods for biochamber that don't use nutrients, are made by people who hate one of the coolest mechanics in game.
And as result all atempts for alternativly powered biochamber I have seen so far just suck.
By restricting it to certain planets, it preserves the intended complexity on agricultural planets where the biochamber has a lot more recipes and the nutrient/spoilage system makes more sense.
And your mod is different.
You clearly want to preserve what makes biochamber cool, and just use it more.
High power consumption (for burner scale) should it even make player feel like fuel usage is similar to nutrient usage.
Have not played it but bookmarked to try it next time.
It feels like good idea, and I thought it would be nice for you to hear it :D
