[Factorio] How do the conveyor belts operate without power?
gpt
Conveyor belts don't need power, they just need to have less friction than the force of objects bring thrown into them. The precision of an engineer's personal assembler should not be underestimated, and any conveyor system big enough for friction to be much of a problem has inserters constantly feeding it momentum.
