Google even has “smart” water, as it showed off its water recycling program today that cools off its data center in Georgia:
Google’s data centers use half the energy of a typical data center in part because we rely on free cooling rather than energy hungry mechanical chillers. In Douglas County, like at most of our facilities, we use evaporative cooling, which brings cold water into the data center to cool the servers, then releases it as water vapor through cooling towers.
Have a look for yourself:
It’s pretty cool that the pipes they use are painted with Google colors.
