These are some very innovative ideas and they totally and completely side step the need of AI for fresh water, leakages and alternative coolants.

No they don’t, if you remove evaporative cooling and go to a closed loop system, the coefficient of performance is almost cut in half. The people building data centers will almost invariably choose evaporative cooling because opex is substantially cheaper.

Why is this downvoted? It's a simple fact of physics that's been fully understood for literal centuries, taught in high school [1]. For a given heat exchanger size, evaporative cooling will always win (well, unless it's raining), with drastically lower thermal resistance.
