Hadley cells bring them inland does it not where it condenses and rains flowing back towards the ocean where it again evaporates and travels inland rains and goes back to the ocean.
Comment on How do AI data centers manage to *consume* water, but when I cool my house, my A/C *makes* water?
cRazi_man@europe.pub 2 days agoEven though there is loads and loads of water on the planet, the amount of fresh/drinkable/usable/accessible water is tiny. This water evaporates and rains back down, but this will most likely fall over the ocean, or on land and go I to the ground, or into some other unusable area/form.
Water suitable for human use is a scarce commodity and needs to be preserved. Of all the water lost to the atmosphere from server cooling systems, almost none of it can be recaptured again.

Why are they not using a closed loop system with condensers collecting the evaporated water?

A condenser will generate the same amount of heat that they are trying to dissipate.

Collect and condense the hot water vapor, concentrate the heat until you’ve got steam; then pump it through a steam turbine recapturing that energy as electricity.
I’m sure there’s some difficulties and nuances I’m not seeing right away, but it would be nice to see some sort of system like this. Most power plants generate heat, then turn that into electricity. Data centers take electricity and turn it back into heat. There’s gotta be a way to combine the two concepts.

The difficulty is, to put it in very simple terms, is that physics doesn’t allow that. The less simple explanation is a thermodynamics textbook, and trust me, you don’t want that.
Everything generates heat. Everything. Everything. Anything that seems to generate “cold” is generating more heat somewhere else.

Actually more because thermodynamics is a cruel mistress.

A condenser can be as simple as a glass dome in a cool room. There is no need for any electricity or heat.

Pretty sure the glass dome traps the heat they’re trying to dissipate.

Note your use of the word “cool.”
