They use adiabatic coolers to minimize electrical cost for cooling and maximize cooling capacity. The water isn’t directly used as the cooling fluid. It’s just used to provide evaporative cooling to boost the efficiency of a conventional refrigeration system. I also suspect that many of them are starting to switch to CO2 based refrigeration systems which heavily benefit from adiabatic gas coolers due to the low critical temp of CO2. Without an adiabatic cooler the efficiency of a CO2 based system starts dropping heavily when the ambient temp gets much above 80F.

They could acheive the same results without using water, however their refrigeration systems would need larger gas coolers which would increase their electricity usage.

Technically yes, but in the current political climate phrases like your initial one are frequently said by right wing wackos to alude to various protected classes indirectly. For example. With your initial comment

and as such the system is beneficial to minorities (specific ones, not all).

The first thing that pops into my head isn’t billionares, it’s alex jones ranting about “the jews” and “the world order”, because the way you wrote that comment had a lot in common with the way those people talk when they’re trying to not say the quiet part out loud.

I think they were meaning the billionare class and they just phrased it very suspiciously.
