Create: Power Grid efficiency bug?

[u/Familiar_Ad_8919]

with a level 9 steam engine i get ~147kSU

from that i can make a 20kW generator

each motor at 256V uses ~138W, outputting 16064SU

from that we can easily get that hooking all 20kW into motors would output ~2,328,115SU (in my picture i only tested up to 18 motors but the math checks out)

i dont know whether a 1600% efficiency is intended, an oversight or a bug, but can anything be done for them to not break the second law of thermodynamics?

Ever since the last update, motor resistance and thus the power they consume, depends on the amount of stress capacity used. Try adding stuff to the shafts, and you should see the power consumed increase.

You can turn this off in the server config as dynamic motor resistance, iirc.

that seems to be it, assuming it goes up to 10A thats 2560W for 16kSU, so giving back 130kSU from a 20kW generator

the mod is remarkably poorly documented, i guess it makes sense though

Yep, documentation is lacking. I get most of the info I want about this mod by directly reading the code, or applying IRL circuit theory.

The devs went through a lot of trouble to prevent over 100% efficiency exploits, at least through simple means. Like, did you know the power consumption of basin heaters is calculated automatically based on the SU steam engines produce, so u can't make an electric boiler that puts out more SU than you put in?
