Luckily there are these rocks which get hot just lying around, more so if you concentrate them, and we have millions of years of current power consumption of those to use. Perfectly CO2 free too.

Unless you're Australia, where we shut down our geothermal trials after some early success.

Ignore those rocks that are already hot, let's keep digging up these black ones and burning them!
