But how do you access the heat of a cubic km of rock three km below ground?
It would take more than a well. A lot of wells.
I love this idea in general but it seems to me it will only work if you find water underground to carry the heat. I am not a geologist
- Retric 4y agoSame basic idea as a well. When you extract water from underground it gets to your borehole through lot’s of tiny cracks greatly increasing the surface area. In some places you can tap into an underground very hot aquifer. In others with sufficient permeability need only need to supply your own cold water. Worst case you also need to crack the rock: https://en.wikipedia.org/wiki/Enhanced_geothermal_system https://en.wikipedia.org/wiki/Enhanced_geothermal_system
