Brought back memories of Jules Verne's "Journey to the Center of the Earth".
Interesting premise : If a geothermal well could tap into a reservoir of supercritical fluids and use them to spin a turbine on the surface, it would be one of the most energy-dense forms of renewable power in the world.
Several challenges though - First is earthquakes an then "Even without an increased risk of earthquakes, supercritical geothermal wells have other drawbacks. Reservoirs of supercritical fluids appear to be somewhat rare, which limits their usefulness in transitioning the world to geothermal energy. And the fluids themselves wreak havoc on boreholes by destroying their liners and concrete plugs."
Will be interesting to see where this goes.
