I wanna plug Fervo energy, as advanced geothermal, where they've got a plant in the US where it's up and running. They tunnel into the Earth and use that to heat up water, and use that temperature differential to generate electricity. Expertise in drilling oil wells can be translated into drilling geothermal pipes instead!
How many wells (and how deep) and on what area one needs for a 1 (one) GWe sustained over 100 years? Timespan is critical too you know, you are cooling the rock below, so heat flow must be kept constant over the life of the plant.
