Geothermal energy has insurmountable problems that go way beyond the drilling.
The corrosive environment destroys all the mechanical and metal components in record time. Perpetually expensive to maintain.

ah that’s what it is. probably worse than desalination where fully 1/3 of the costs are involved with maintenance. (the other two thirds are 1/3 capital costs & 1/3 energy costs.)
Hmm, I would hazard that sometime in the next 10 years or so the people doing materials research will come up with coatings that are both super water phobic and super resistant to corrosion. If you ever read physorg you see a relatively constant flow (as in 2-4 times a year) of materials with these characteristics. The addressable market for this in the water desal business alone is huge.
