Imagine if you built a data center was on a river that was fed by mountain snow melt, and you created a diversion that took some of that water, ran it along heat exchangers in your racks and the out through a hydro-power unit and back into the river on the other side. You might be able to build the first negative PUE data center in the world.
But you wouldn't tell anyone about it lest you lose your competitive advantage!
The Google datacenter a few miles from my house my house is right next to the Chattahoochee river. They take water from the treatment plant that was going to be pumped into the river to use in their heat exchangers. Then they clean it and pump it into the river.
