Large Bronze boiler has 20% efficienty compared to High Pressure Coal Boiler... Soo, why someone would make big boiler instead of small ones beside liquid fuel? Or is it better material = better efficienty ?
nevermind, portable debuger sad my problem.
Yeah how did you get the 20% efficiency figure? I have wanted to see math on the Large Boilers for a while, but haven't gotten to do it myself yet.
