Nasa believes drilling up to six miles (10km) down into the supervolcano beneath Yellowstone National Park to pump in water at high pressure could cool it.

This would be one of the only times I would be in favor of a private/public partnership.

The US government could fund the drilling of the wells.

A private investor owned electric company would build a geothermal electric generating plant to use the steam generated by the wells.

It would be a true win win endeavor.

The electric company would get the power generated by the volcanic vent and the government would be freed from the cost of building and operating the plant and of the cost of maintaining the plant and cooling water pumps (and various other things).

Methinks the heat sink in the Earth’s mantle and core exceeds the cooling water reservoir capacity, possibly even that of the world’s oceans. Gravity then just keeps it coming.

Problems even if attempted, melting the pipes, water chemistry, water source for the volume of water required to transfer the heat, cooling towers and the atmospheric impacts,...no more blue sky over the area, won’t even talk about acid rain possible systems evolving.
