Thread: Could we use Earth's mantel for electricity.

Could we put an electric generator that works on heat into Earth's mantel?

mantle...

Yes. It's called geothermal electricity.

Strictly speaking we are not tapping the mantle, but the crust. Now you could argue that the heat was coming to the crust from the mantle. In which case I would ask why you do not say we are tapping the heat of the accretion disc.
