> closed circuit cooling systems don't evaporate any fucking water.
Nobody uses closed circuit cooling systems anymore. Pretty much every datacenter is cooled by evaporative (open loop) cooling.
The enthalpy of vaporization of water is pretty high, so for a relatively large energy use, they only need to evaporate quite small amounts of water. A single household water supply (10GPM), on full blast, could cool 1.5 megawatts of computers - a small datacenter.
