CSIRO Supercomputer to use Geothermal Cooling

Over at The Register, Richard Chirgwin writes Australia’s CSIRO plans to use Geothermal cooling for a new petascale supercomputer. Located in bone-dry Perth, the system will be used to process data from the Square Kilometer Array Pathfinder (ASKAP) telescope.

The water to cool the Pawsey machine will be drawn from an aquifer 100 meters below the surface, into a heat exchanger to provide cooling for the computer, and then returned under pressure to the aquifer, with no net loss of groundwater.
