simple. Geothermal power is by far cheaper and more accessible. Space solar is a side show, it won't get us habitats in space and it won't compete well at all with terrestrial forms of power.

In fact, the awkward truth is that space solar is a way to make solar power so exorbitantly expensive to start up that nuclear power starts looking rosy by comparison. Thats not a good sign.

all geothermal power options are not equal. Dry rock for instance is a lot more hazardous.
The ideal would simply create a closed circuit with a pooling area at the bottom, and this would not cause
problems like this place did because the water would not be going out into the surrounding rock.

this is just to be fair. It should be noted that this is all about one plant thats operating too close to the magma
and not using double closed circuit.
