Were you expecting a massive meteor impact in the near future that the rest of us are unaware of?
If not, exactly how were you planning to get enough heat at the surface of the Earth to warm-up the core?
- ComradePhil 5y agoDo you think we drill to the very core to get thermal energy? Well, I have disappointing news for you: The earths radius is 6,371 km; for thermal plants, we dig like 5 km. While the core is 5000 degrees celcius, the point we dig to is more like 150. Concentrated solar power can generate 1000 degree celcius. If we pump this down when we have excess, the area remains hotter than it would otherwise be... letting us use it when the sun sets. This can also work through much longer timescales, like you could dump energy heat down in the summer and harvest it in the winter. The post I was replying to was worried about gradual loss of core heat. This will be minimized if we pump heat in.
