Now all we need to do is borrow the drills, take them somewhere other than Chile (the middle of Argentina, say) and see how far down they can drill. At the bottom of the shaft, measure the temperature. If it's above 100°C, we know how far we have to drill to achieve geothermal powerplants without being next to a tectonic plate boundary or a hot spot. It'll be a double whammy of brilliance!
