The Rotary excavator mines coal deposits in the ground, and is the easiest and cheapest way for Tycoon players to get coal in the start of the game. Eco players may not build these without unlocking Tycoon buildings.
Coal is needed for both the Coal Power Production Chain and anything dependent upon iron, though the Rotary Excavator may be replaced with the Coal Mine which is twice as productive. The primary benefit of the Rotary Excavator is that it doesn't use a mine slot like a Coal Mine. The extractor also does not consume power like the mine. However, for the same amount of coal, The extractor produces 5x the pollution, and takes up a large amount of space.
