5:40 I think you mean trending towards solar?
It's Crack, not Sea Rack
This reminds me of Rain World, minor spoilers but not too bad:
In rain world one of the main plot premises is that these superstructure city-sized, absolutely gargantuan biomechanical supercomputers require a small sea's worth of water to cool themselves while running their computations and processes. The reason the game is called rain world is because the exhausted steam and evaporated water accumulates in such mass that it completely altered the world's global climate. What we're doing is a much smaller scale but still a massive amount of water being displaced and evaporated in places that water typically isn't found. I wouldn't be surprised if we notice effects on the local climates these massive data centers are located.

Love it. The video not the datacenters
Green people , Comments ?
4:18 Wow, subtle face reveal.
Both pronunciations are acceptable for 'gigawatt'
dave turn you r mu sic Down sin dr home
71% of the earth surface is water.. you need hella lot of databases to even impact the amount of water available on earth. Like you will need a significant volume of the northcap because that is significant for our waters to keep level.. you see the northcaps fit on a tiny amount of 30% available land on earth? Think twice please..
What if we got rid of the Golf Courses
Well, when you take out the heat, and use that to heat neighboring apartments and their hot water, you get much better power efficiency. Problems with legacy operators, like Google, is that they boast loudly "how efficiently we can loose the heat", when the real question is "where can we dump this heat, for re-use?". Google uses cold sea water, and boasts about their "efficiency of loosing heat energy!", while real and smart engineers, pump the heating to the area to be used elsewhere.
Again, not too applicable in Singapore, but there are data centers, also Google data centers, in the areas where heating is needed, and a lot of it in certain months of the year.
Sounds like we need to get rid of golf courses.
Data Center HVAC Engineer here. Your description of the recooling stages is mostly outdated today. No datacenter that i know of uses a open secondary chiller. They have allmost all been phased out. We use 2 closed loops, one for the whitespace, one as a recooling loop for the chillers. They can be run in "free cooling" wereas the system just chills the water via plate heat exchangers without running compression based cooling. Here in europe we run free cooling around 60% of the year round. If we need emergency cooling, we can switch to a adiabatic solution witch uses watermist to increase the efficency of the recoolers.
Watercooling is nice, but except from some high density solutions we build, the cost to use and maintenace isnt worth it.
Everybody seems to hate on the energy used by datacenters, but what is the alternative? We are operating about 13 DCs with PoEs from 1.37 to 1.19. There is not mutch more to gain here.

Heat = power = send to people
Water isn´t a problem. It literally falls from the sky.
Telia's Helsinki HDC dumps the heat to district heating, so reusing the heat that way. It wasn't still online couple of years ago when i visited because the datacenter didn't produce enough heat at that point as migrations to the new datacenter were still on-going, but i think it's online these days.
PV panels will deliver substantially better performance if the panel temperature is kept under 30C.
One major flaw of that technology.
I think you addressed another issue. Why do 2 golf courses use as much water as a datacenter. These datacenters serve millions of people and handle banking, communications etc. While these golf courses serve like 1000 members for leisure. 😊
Just today I was trying to find an ASHRAE diagram reference document… Their site is all marketing, I haven't found any actual engineering documents
How many bottles of Coca Cola is that ?
In Minnesota, we get free cooling for data centers when the ambient outside temp is below about 32 degrees. It works using an external machine called a "dry cooler" which is basically a large fan cooled radiator that cools the external water loop. It gets rid of enough heat to require no evaporative cooling during colder months, so evaporative cooling works in the summer and free cooling in the winter.
One quick correction – in an evaporative cooling tower, part of the water falling down against the forced air coming upward evaporates and absorbs (not loses) heat energy, evaporation being an energy absorbing process. Source: I've been a data center manager for about 10 years, running both University and corporate DCs, and I'm the one who got to do all the statistics, models, and try to find efficiency improvements.
More ways to enslave and spy on people . . . No perception of privacy – Prison Planet?
4:41 "The evaporated water leaves the tower as steam." No, it does not. It leaves the tower as water vapor. Steam is another thing entirely. It only exists at temperatures much higher than those associated with cooling computers.
A closed loop system, is a closed loop system. So most cooling is, almost all cooling is closed loop. So your premises is not completely honest. It is suggestive and misleading. Most datacenters use virtualization to exactly use most compute capacity, so your assumption is wrong, virtualization starting in 2003 forward radically changed utilization curves. I designed and built datacenters, so I can tell you utilization is since 2003 is actually well over 90% at the low end, and pushes 95% at the high end, regardless of scale using virtualization of various types, such as VMware, docker, etc. Sorry but you should be careful to qualify the use of closed loops, and localized electrical sources such as solar or geothermal. Datacenters even use termal ground loops or taps were applicable. You clearly made many generalizations and assumptions that are not sound from a global implementation stand point.
Watching this while pooping in a large data center
Metric!!!! 99% of us are not in the Dark Ages when it comes to water
Can you please elaborate more on the Microsoft barrels? They seem to be interested in putting them in my country (Greece) and I have many questions on how they work. Tbh it looks like a great power saving idea. It would be great a video about them ❤
"gallons" is a measuring unit that is used in ONE single country that I am aware of, and it's unknown by everybody else in the world. Your videos would look more profesional and way more quality if you use international units instead. I suggest you to avoid these local units altogether and switch to international instead. You must understand that MANY people would really appreciate that. Thank you
The clear takeaway from this video is the fact that a golf course takes more water than a hospital 😮
Why can't a data Center have its own miniature nuclear reactor for power, they need cooling water circulation as well couldn't they work together?
Please do more videos like this one discussing the cooling infrastructure of modern data centers!
"or 2 18 hole golf courses" Golf sucks.
Data centers should be built in cooler climates, cooler due to the region being at a higher altitude or cooler due to being farther North.
1:10 I think you forgot some digits here. 5000 servers is nothing. With 1U servers, 25-30 servers per square metre of datacenter floor is very conservative.
12:39 Hehe…do do.
Generating 5 tited asian waifus in a second is worth not having glaciers
Honestly there are ways to transfare the heat towards the air without releasing so much water they just cost more.
It would make more sense to manufacture chips that aren't so ridiculously compact, that they become an oven, at last when it comes to data centers. Of course that would impede the "endless growth model" for chip makers, so that's obviously never going to happen.
I would love a video on how a natural gas power plant works compared to Coral
Guys, hear me out. Have you ever played Rain Worl…
hyperscale? 5k servers? lol boy DCs can have well over 100k servers
Ah yes, the American football field metric. One of the most useless metric ever existed.
I wish I had a heat pipe to my home.
People need to get back to on-premise computing. cloud costs can be ridiculous.
@12:40 – you said "do do"
And all of this heat, domestic and commercial, is sunk into the atmosphere where it further increases global heating. And before I get tongue lashed, yes, I do understand that globally it is not a significant increase and to that I invite you to come spend an August afternoon in Central Texas sitting outdoors next to my condenser unit where we can discuss the significance. You'll require plenty of iced sweet tea; Fortunately I, Texan through and through, have plenty on hand.
This only happens because we have, historically and currently, dramatically underpriced water. When your water is nearly free, it makes sense to reduce your power bill (which costs you actual money) by consuming some water for evaporative cooling (which is close to free). Same thing with power plants; they use evaporative cooling because the water costs them a tiny fraction of what it's worth.
It's entirely possible to have an electric grid that consumes no water whatsoever; renewables do this naturally, and even thermal power plants can be cooled in other ways (at the cost of consuming some of the produced electricity to drive the cooling). Data centers could entirely operate from air conditioning (to air or ground) or, even more efficiently as you note, with free-cooling (potentially coupled to watercooling inside the facility). As you pointed out, hard drives are one of the more temperature-sensitive components, and they'll still tolerate 45C or so just fine; well above ambient temperatures in most locations. There's no reason you even need to use air conditioning if you can transfer the heat from your components (which only need to be kept somewhere between 40c and 90c) directly to the surrounding air and get rid of the heat passively.
