I think this problem may be one if the classic solid state is not actually better than the old-school mechanical solution.

As an experiment, it would be fun to architect 2 designs. One that has a fancy microwave or thermal rock melting setup, one that has a traditional rock drilling approach, both powered by a nuclear power source. Add up the cost of ownership for both, and I'd bet the mechanical solution comes out on top.

Fully agree

With current technology. But the point of this is to get a starting point for solid state and improve afterwards. Very much like how jet engines came to be better than propellers.
