Spike, most of the current issue of the IEEE Spectrum is about cooling
processors.

But that's not the problem.  Data centers are designed to minimise
cost. If they could make them cheaper in van-sized units, they would.

Submerge the processors in water, perhaps in pressure cookers, pump
down to about 3 kPa, where water boils at about room temperature, cool
with that.  The... hey let's borrow the name CyberTruck would then
need a compressor to pump water vapor from 3 kPa to 100 kPa.  That
would be more reliable than air cooling.
