Trying to educate them that water and power usage are the less problematic parts and not as bad as everyone thinks. It's the noise and lack of green power that are the problems.

Can you please provide us the details how much water an open-air, evaporative cooling system loses due to evaporation and other system-wide losses?

Also can you tell us which chemicals need to be added to the outer and inner loops of the systems, and do the inner loop has the same losses or it is different.

If there's water loss into the ground, and if the water is treated with chemicals, is it required or is it in fact treated to remove these chemicals so the used water can be reused for livestock, agriculture, or non-consumable use in the cities like for watering greenery or other processes which needs water but can accept non-potable variety.

I also heard that there's a closed loop version for outer loop. Is it used widely in US, if yes, what percentage of the large datacenters use it? Because as I heard it, it's more expensive, but doesn't lose water as much.

Adding some references if possible is greatly appreciated so we can dive deeper, as the community.

Same is also valid for power usage metrics. I'm especially interested in how a datacenter full of 800VDC systems (aka Megawatt Rack) can be fed without any difficulty with our current power generation and transfer infra.

Imagine taking half the cars off the road because they no longer need to be there, and then re-run your ecological calculations.

Can you elaborate a little more? I failed to catch what you're trying to say. Sorry.

> water ... usage are the less problematic parts

Except when some rich clown from another country comes into a drought-stressed desert area where residents have already been under increasingly draconic water usage restrictions for goin' on a decade now, wantin' to build a datacenter right on a lake that's already under severe stress with record low water levels, tellin' everyone it won't have any effect on anything and it's all just rainbows and sunshine and nothin' but benefits for everyone all around (lies). But yeah, no worries. We can surely trust the billionaire wouldn't lie to us to enrich himself at our expense.
