Obviously you'd need to light up the chillers in the summer, but running them 4 months out of the year seems like a huge energy savings than running them year round.

	<htmltext>If it wasn't for the required internet connectivity google could go off the grid completely. But they already own so much fibre and the public internet seems to need google more than they need it. <br> <br>

Soon they will generate all their own power from wind and solar, convert all their employees shit to power so they don't need the sewerage system either, send all their traffic through the network of low earth orbit satellites they are about to launch which also conveniently beam solar power back down to them.<br> <br>

So basically at the end of the day they will be able to buy or swindle a plot of land from some country with low tax, bring in all their own employees, contribute absolutely nothing to the local economy and leave when the sun goes down. It's great really, saves them on lawyers that would otherwise help them pussyfoot through the swaths of modern over-regulation and the satellites will help them get past any censorship / connectivity problems.<br> <br>

And if China start shooting down their satellites, Google will make satellites that shoot back</htmltext>

Of course, for the rest of the world, having just one major data center is a big investment and the idea of maintaining excess capacity in case the weather in Belgium is not favorable is a complete fantasy.

	<htmltext><p>The short answer is yes --- water takes a staggering amount of energy to change temperature (it's one of the many properties the stuff's got that's really weird). A big lake makes an ideal dumping ground for waste heat. What's more, the environmental impact is going to be minimal: even the biggest data centre isn't going to produce enough waste energy to have much effect.

The specific heat capacity of water is about 4kJ/kg.K, which means that it takes 4kJ to raise the temperature on one kilogram of water by one kelvin.

A small lake, say 1km x 1km x 10m, contains 10000000000 litres! So you're going to need to run your data centre for ten million seconds, or about 110 days, to raise the temperature by one measly degree.

	<htmltext>Remember that even on hot days not all of the traffic through the datacenter needs to be rerouted, and I'd imagine that a location selected for a datacenter like this was chosen for the infrequency of days that will require rerouting.  Do you know how much it costs to cool a datacenter, and how much this will save?  I don't, but Google probably does, and they probably wouldn't make a decision to do something like this without comparing the savings with the potential cost from decreased lifespan of computers running hot and losses due to downtime.  I would also imagine that Google will be working to greatly increase stability during rerouting, given the comments from the end of TFA about other power saving uses, such as routing traffic to datacenters where it's night, meaning "free cooling" can be used since it's colder outside, and off-peak electricity rates are in effect.
<br> <br>
I think the concept is interesting, and it makes me wonder if we'll see more datacenters built in areas of the world more conducive to projects like this in the future.</htmltext>

<sentencetext>Remember that even on hot days not all of the traffic through the datacenter needs to be rerouted, and I'd imagine that a location selected for a datacenter like this was chosen for the infrequency of days that will require rerouting.
Do you know how much it costs to cool a datacenter, and how much this will save?
I don't, but Google probably does, and they probably wouldn't make a decision to do something like this without comparing the savings with the potential cost from decreased lifespan of computers running hot and losses due to downtime.
I would also imagine that Google will be working to greatly increase stability during rerouting, given the comments from the end of TFA about other power saving uses, such as routing traffic to datacenters where it's night, meaning "free cooling" can be used since it's colder outside, and off-peak electricity rates are in effect.
I think the concept is interesting, and it makes me wonder if we'll see more datacenters built in areas of the world more conducive to projects like this in the future.</sentencetext>

	<htmltext>I've got one word for you:  Iceland.
<br> <br>
They sit where temperate ocean water meets cold arctic air, resulting in a relatively narrow and predictable temperature band which happens to be perfect for cooling datacenters with minimal, if any, conventional HVAC.  Their power is green, and they have lots of it.  They use a combination of hydropower and incredibly abundant geothermal heat for power generation.  Recently, undersea fiber cables have been laid down, greatly increasing their connectivity to the outside world.  Not to mention that these days, the cost of doing business there is fairly attractive.
<br> <br>
I suppose that a detractor could observe that Iceland is a geologically active area, but then again so is Silicon Valley.

If Google had some real foresight, they'd be investing in an Icelandic datacenter right now.</htmltext>

<sentencetext>A check of one weather site indicated that the maximum recorded temperature it had for Brussels was 96  F. Most server equipment is happy with a true ambient temperature of 90.
That may put the exhaust temperature at 110 or so.
With a single pass system (venting the exhaust directly outdoors, and bringing in new air from outside) an external temperature of 90 could work.
Since the average high temperature in Brussels is apparently 71, only in pretty severe heat waves where temperatures exceed 90 would a data center need to shut down.At cooler temperatures more traditional systems could be utilized to manage internal external heat exchange.</sentencetext>
