Thought I'd share a view of my short-lived geothermal plant. It didn't last long, charging lapotron crystals drained the lava lake.
I'm thinking of rebuilding it over a new borehole.
The second one is really odd, I've noticed that flowing lava seems to spontaneously turn to cobble, possibly at server restart?
In this case it seems to have turned to stair blocks?
Unless someone actually built that?
