>build geothermal powerstation above large caldera and/ or volcanic hotspot
>adapt oil drilling technology to pump in water and return steam
>liquid water jacket on the outside of the drill tubing for cooling/ heat absorption
>steam return in the center
>heat transfer from the flowing water keeps the drill cool, allowing the rig to get closer to the magma chamber and extract much more energy
>each borehole would be equivalent to a coal fired powerplant
>it's about as hard to make a borehole as it is to make one for extracting oil
>make lots of boreholes for cheap
>vast amounts of extremely cheap clean energy
>???
>profit!
