Stirling engines work, but they tend to be rather low power, low torque devices.
But they’re definitely a solution for .023% of our energy problems, and certainly ripe material on which to write many grant requests, conduct studies, and get tremendous government funding.
Very astute analysis! LOL.
Al Gore said last month that the center of the earth is several million degrees and all we have to do is dig a few holes a couple miles deep to get unlimited free energy.
The demonstration engines certainly are low power/torque devices, but they don’t have to be.
What is needed (and feasible in a fix/stationary situation like this) is to get the temperature differential as wide as possible, and set it up with as long a stroke as possible.
The attraction here is high thermal efficiency in converting an external heat source to mechanical energy - ie, at better efficiencies than many solar cells are going to do for you today.

Yup, low power, low torque, usually with high operating pressures required.
