I wasn't even counting the combustion part, just the heat to steam to electricity part (common to coal and nuclear plants).
I had assumed they would need to transfer the heat rather than pipe geothermal steam directly into the turbine, but either way, solar and wind is very cheap and hard to compete with. Even magical free energy connected to a steam turbine struggles when you do the sums, which is the baseline before you start including cost and risk from super deep drilling.
