"The water-cooled supercomputers require 1.7 million gallons of water per day to function."

Anyone have a citation for that? I suspect that water is in circulation. I doubt they send almost two million gallons into the sewage system everyday.

I did a quick calculation for the energy consumption of Tianhe-2, which has a power consumption of 17808 kW ...

1,538,611,200,000 J per day. Of course the Tianhe-2 is rated as the fastest, and the NSA won't be using something as big, but it gives you a rough idea of the power consumption of these machines.

Water could be lost in evaporative cooling towers.
