-- MV Electric Furnace |
K |
2 |
-- This is a faster version of the stone furnace which runs on EUs |
|
3 |
-- In addition to this it can be upgraded with microcontrollers and batteries |
|
4 |
-- This new version uses the batteries to lower the power consumption of the machine |
|
5 |
-- Also in addition this furnace can be attached to the pipe system from the pipeworks mod. |
