Do you honestly think that the very detailed understanding of cooling systems that you have has anything in common with the popular opinion that datacenters use lots of water?

Also, you are arguing jargon...and data centers use completely closed loop designs where it makes sense (very cheap power) and use what you describe where it makes sense (with more expensive power and cheaper water). Finally, nothing you said disproves that there is a significant propaganda effort to demonize datacenters by a foreign power.
