I've wondered as well about the effect of pumping all of that heat - energy - out of the core and into (effectively) space. Best case, our use falls in the .003% mentioned in another thread of heat that contributes to warming the Earth's crust, and the surface is that .003% cooler. The worst case, though, is we start slowing (maybe even stopping) the flows of molten rock as it's cooled down. I don't even have the beginnings of a background to comment - does anybody?
