Finding a magma pocket on a planet with no current volcanoes is a bit lucky, but ok.
Build a electrical plant/water facility;
We will pump sea water into our facility, boil the water to power electric turbines and sell as distilled water, then take the melted salt and cast it, then sell it.
Suppose I should terraform too; Since we’re drastically increasing volcanic activity, we’re going to build some air filters to start removing volcanic gases from both our atmosphere and our facilities.
Notes:
Salt can be perfectly melted by lava, as lava is temperature of 1200C, while salt melts at 400C and boils at 1800C.
I’m likely going to have import the seawater for now, I’ll remedy that soon.
Since I’m now using heat, I’ll likely start having to remove slag from the lava pipes soon.
