Its probably stupid but I actually think that a good addition to this game would be a steam engine. The inputs would be water and either coal or lava and obviously the output would be power.
I thought of it while on the map caldera when I saw the water and the lava next to each other
I like this .. I was thinking about the same thing.. although the water/lava is already done with the stone farmer and so it would be like taking that one reskinning it to look like a generator ie the coal gen but with blue/red/grey out putting maybe 10% less power but even cheaper build than the oil refinery but a distribution method like that of the power amplifier... O.o idk if anyone can understand that thought process lol
