Hi. This is mostly personal consumption but to explain the changes:
I lowered the cost of loaders from 50x /100x of a material to cost /10, e.g.:
100 gears -> 10 gears
50 circuits-> 5 circuits
I didn't change the recipe regarding this.
The electrolysis plant and fuel refineries have their power usages restored. I think you can make a positive feedback loop regarding lower power usages on these machines but IMO, it's so absurdly space inefficient that I'd rather build a nuclear power plant.
