What do you mean? It's already in the core and gradually reaches us through the crust. What's your point/distinction here, exactly?

It was not initially in the rocks that we are tapping for geothermal energy, which would be a few kilometers. I wasn't talking about the Earth as a whole. Remember, this is about why so much more thickness is needed for the rocks for ordinary geothermal energy systems, vs. artificial geothermal.
