Every wanted to be independent of electricity?
Now you can. With the Burn the World mod. You get every kind of machinery in a "burner" form, which means they need fuel to operate instead of electricity. This also comes with alternative research options, so you do not need to research any of the pesky electricity related technologies.
Everything from assemblers to science labs to oil facilities has a fuel burning alternative.
Difficulty
This mod is a step up in difficulty from stock Factorio. Not only the logistics of adding fuel everywhere is complex. The recipes that make the burner related items are also a step up in complexity.
WIP
Currently it is possible to play this "fuel only" up to tear 3 science. Which should provide you with hours of work already.
There is no "burner roboport" yet, and the "burner rocket silo" is made but not available yet.
