I wanted to do a playthrough with Krastorio 2 and Space Exploration. SE uses AAI Industry.
This is just an example and is probably not what the recipe is anymore.
The AAI Industry belt recipe uses 1 motor / 2 belt segments which seems like a bad ratio to me.
Vanilla Factorio: 2 transport belt: 0.5 sec, 1 iron gear, 1 iron plate,
AAI Industry: 2 transport belt: 0.5 sec 1 iron plate, 1 single cylinder engine
Tweak: 10 transport belt: 2.5 sec, 1 iron gear, 5 iron plate, 1 single cylinder engine, 1 coal
Each plate will still make two belt segments and conceptually the engine can drive >2 segments with a gear at one end of each section to link to the motor.
A type of motor called Pyréolophore https://en.wikipedia.org/wiki/Pyreolophore can run on powdered combustibles so coal is included.
It is difficult to determine how much coal to include since it would be consumed on operation but at least this is in the realm of sense.
